Succulent Care Guide: Keeping 25 Popular Varieties Alive Indoors

The Soil That Kills and the Soil That Saves

Standard potting soil holds 40 to 50 percent water by volume. Succulents need soil that holds 15 to 25 percent water by volume and drains completely within 30 seconds of watering. The difference between these two soil types determines whether your succulents thrive or rot.

The Standard Succulent Mix

Combine 1 part standard potting soil, 1 part coarse perlite (size 3, 4 to 8 millimeter granules), and 1 part coarse builder's sand or poultry grit (granite chips, 1 to 3 millimeters). This ratio produces a mix with 25 to 30 percent water-holding capacity and excellent drainage. For a single 4-inch pot, mix 1/2 cup of each ingredient. For a 6-inch pot, use 1 cup of each. For a batch to fill ten 4-inch pots, combine 5 cups of each ingredient in a bucket. This mix costs $0.15 to $0.25 per 4-inch pot using bagged ingredients.

The Gritty Mix (for Species Prone to Rot)

Species like Lithops, Conophytum, and sensitive Echeveria varieties benefit from an even leaner mix: 1 part standard potting soil, 2 parts coarse perlite, and 2 parts poultry grit. This mix holds only 10 to 15 percent water and forces the roots to grow in search of moisture, producing a denser, healthier root system. The gritty mix also prevents the soil from compacting around the stem base, which is a common cause of basal stem rot in Echeveria and Graptopetalum.

Top Dressing

Apply a 1/4-inch layer of clean gravel or poultry grit on the soil surface after planting. The top dressing keeps the lower leaves of rosette succulents (Echeveria, Sempervivum, Aeonium) elevated above the moist soil surface, preventing contact rot. It also discourages fungus gnats (Bradysia species), which lay eggs in moist organic soil. Fungus gnat larvae feed on succulent roots and create entry wounds for fungal pathogens. The gravel layer eliminates the moist organic surface that attracts egg-laying adults.

Light: The Second Most Critical Factor

Succulents native to desert and semi-desert environments require 6 to 8 hours of direct sunlight per day to maintain compact growth and vibrant color. Indoors, a south-facing window provides 4 to 6 hours of direct light in winter and 5 to 8 hours in summer, depending on latitude and window overhang. An east-facing window provides 2 to 4 hours of morning direct light. A west-facing window provides 3 to 5 hours of afternoon direct light. A north-facing window provides no direct light and is unsuitable for most succulents.

Recognizing Insufficient Light

When succulents do not receive enough light, they etiolate: the stems stretch toward the nearest light source, the internodes (spaces between leaves) elongate, and the leaves become smaller, paler, and more widely spaced. An Echeveria elegans that should form a 3-inch rosette with tightly packed leaves will stretch into an 8-inch-tall stem with a 1.5-inch rosette at the tip within 4 to 6 weeks of low light. Etiolation is irreversible. The stretched growth cannot be compressed back into a compact form. The solution is to move the plant to a brighter location or supplement with a grow light.

Grow Light Options

A full-spectrum LED grow light (45-watt panel, $25 to $40) positioned 12 to 18 inches above the succulents provides sufficient light for 4 to 6 hours per day. Run the light on a timer set for 12 hours on and 12 hours off to simulate a natural day-night cycle. Succulents under LED grow lights develop more compact growth and stronger leaf coloration than those relying on window light alone, particularly from November through February when daylength drops below 10 hours at northern latitudes. A single 45-watt LED panel covers a 2x4-foot shelf area and is sufficient for 15 to 20 small succulents.

Acclimating to Direct Sun

Succulents grown indoors under low light will sunburn if moved directly into full outdoor sun. Sunburn appears as white, brown, or black scorched patches on the leaves, typically on the side facing the light source. Acclimate plants by placing them in dappled shade for 3 to 5 days, then partial shade for 3 to 5 days, then full sun. The entire acclimation process takes 7 to 14 days. Sunburned leaves do not recover but the plant will produce new, sun-adapted growth if the damaged leaves are left in place to provide some shade to the developing growth tips.

Watering: How, When, and How Much

The soak-and-dry method is the standard watering approach for all succulents. Water thoroughly until it drains from the pot's drainage holes, then wait until the soil is completely dry before watering again. The interval between waterings varies by species, pot size, temperature, and humidity. The guidelines below assume indoor conditions at 65 to 75 degrees Fahrenheit and 30 to 50 percent relative humidity.

The Finger Test

Insert your finger into the soil to the second knuckle (approximately 1.5 inches). If the soil feels moist at that depth, do not water. If it feels dry, water. For small pots (2 to 3 inches), insert a wooden toothpick into the soil. If the toothpick comes out clean and dry, the soil is ready for water. If it comes out with moist soil particles clinging to it, wait 2 to 3 more days. This test prevents the most common mistake: watering a succulent whose soil surface is dry but whose root zone is still moist 2 inches below.

Watering Frequency by Season

Spring and summer (active growth period): water every 7 to 14 days for most species. Fall: reduce to every 14 to 21 days as growth slows. Winter (dormant period for most species): water every 21 to 35 days. Some winter-dormant species (Lithops, most Echeveria) need no water at all from November through February if kept below 60 degrees Fahrenheit. Summer-dormant species (Aeonium, Aloe, Gasteria) need reduced water from June through August. The seasonal adjustment is critical. Watering a winter-dormant succulent on a summer schedule causes root rot within 3 to 4 weeks.

Water Quality

Tap water contains dissolved minerals (calcium, magnesium, sodium) that accumulate in succulent soil over time. After 6 to 12 months of tap-water irrigation, a white crust of calcium carbonate forms on the soil surface and pot edges. This crust is harmless to the plant but indicates mineral buildup that can eventually affect root function. Use filtered water, rainwater, or distilled water if mineral buildup is visible. Alternatively, flush the soil every 3 to 4 months by pouring water through the pot until it runs clear from the drainage holes for 30 seconds. This leaching flush dissolves and carries away accumulated salts.

25 Species: Individual Care Profiles

Each species below has specific requirements that differ from the general guidelines. Treat these profiles as your primary reference for each plant in your collection.

1. Echeveria elegans (Mexican Snowball)

Rosette to 4 inches, powdery blue-green leaves. Light: 6 hours direct sun. Water: every 10 to 14 days in summer, every 21 to 28 days in winter. Temperature: 50 to 80 degrees Fahrenheit. Soil: standard succulent mix. Common problem: mealybugs in leaf axils. Treat with 70 percent isopropyl alcohol on a cotton swab applied to each visible insect. Reapply every 5 to 7 days for 3 weeks.

2. Echeveria 'Lola'

Rosette to 3 inches, lavender-pink leaves with powdery coating. Light: 6 hours direct sun. Water: every 10 to 14 days in summer, every 21 to 28 days in winter. Temperature: 50 to 80 degrees Fahrenheit. Soil: standard succulent mix. This variety is prone to etiolation in low light and basal rot in humid conditions. Ensure excellent airflow around the rosette.

3. Haworthia fasciata (Zebra Plant)

Clumping rosette to 5 inches, white horizontal stripes on dark green leaves. Light: 4 to 6 hours, tolerates bright indirect light better than most succulents. Water: every 14 to 21 days year-round. Temperature: 55 to 80 degrees Fahrenheit. Soil: standard succulent mix. One of the best succulents for offices and rooms without south-facing windows. The windowed tips on the leaves are translucent and function as light conduits to the interior leaf tissue, allowing photosynthesis even when the plant is partially shaded by surrounding vegetation in its native South African habitat.

4. Haworthia cooperi

Clumping rosette to 2 inches, translucent bubble-tipped leaves. Light: 4 to 6 hours with some direct sun. Water: every 14 to 21 days. Temperature: 55 to 80 degrees Fahrenheit. Soil: gritty mix (extra drainage). The translucent leaf tips are the plant's most distinctive feature and become more pronounced in bright light. Protect from direct midday sun, which scorches the translucent tips.

5. Aloe vera (Aloe barbadensis)

Rosette to 24 inches, thick gray-green spotted leaves. Light: 6 to 8 hours direct sun. Water: every 14 to 21 days in summer, every 28 to 42 days in winter. Temperature: 55 to 85 degrees Fahrenheit. Soil: standard succulent mix. Aloe vera produces gel containing acemannan, a polysaccharide with documented wound-healing properties. The gel from a mature leaf (3 years old or older) contains the highest concentration of active compounds. Cut a leaf from the outer base of the rosette with a clean knife. The leaf does not regrow from the cut point, but the plant produces 2 to 3 new leaves per year from the center of the rosette.

6. Aloe 'Delta Lights'

Clumping rosette to 12 inches, variegated green and cream leaves with pink edges. Light: 6 hours direct sun. Water: every 14 to 21 days. Temperature: 55 to 85 degrees Fahrenheit. Soil: standard succulent mix. The variegation is stable and does not revert. More sun exposure intensifies the pink leaf margins.

7. Crassula ovata (Jade Plant)

Shrub to 36 inches, thick oval leaves on woody stems. Light: 4 to 6 hours direct sun. Water: every 14 to 21 days in summer, every 28 to 35 days in winter. Temperature: 55 to 75 degrees Fahrenheit. Soil: standard succulent mix. Jade plants live 50 to 100 years indoors with proper care. They bloom in winter (December to February) when exposed to cool night temperatures (50 to 55 degrees Fahrenheit) and dry conditions for 4 to 6 weeks in fall. The flowers are star-shaped, white to pale pink, and appear in clusters at the stem tips.

8. Crassula ovata 'Gollum' (Trumpet Jade)

Shrub to 36 inches, tubular leaves with red-tipped suction-cup ends. Light: 6 hours direct sun. Water: every 14 to 21 days. Temperature: 55 to 75 degrees Fahrenheit. Soil: standard succulent mix. Same care as standard jade plant. The tubular leaves are a somatic mutation that is stable in cultivation.

9. Sempervivum tectorum (Common Houseleek)

Rosette to 3 inches, green to burgundy leaves with cobwebby hairs. Light: 6 hours direct sun. Water: every 14 to 21 days. Temperature: 40 to 80 degrees Fahrenheit (cold-hardy to zone 3 outdoors). Soil: gritty mix. Sempervivums are monocarpic: each rosette flowers once and then dies. The plant produces offsets (chicks) around the base of the mother rosette (hen) before flowering, ensuring the colony continues. Remove dead rosettes after flowering to prevent fungal growth on the decaying material.

10. Aeonium arboreum 'Zwartkop' (Black Rose)

Rosette to 8 inches on a 36-inch stem, dark burgundy-black leaves. Light: 6 hours direct sun. Water: every 14 to 21 days in fall through spring (active growth period). Every 28 to 35 days in summer (dormant period). Temperature: 45 to 75 degrees Fahrenheit. Soil: standard succulent mix. Aeoniums are summer-dormant, the opposite of most succulents. They actively grow from October through May and slow or stop growth from June through September. Watering on a summer schedule during dormancy causes root rot.

11. Kalanchoe blossfeldiana

Shrub to 12 inches, scalloped green leaves with clusters of red, pink, orange, or yellow flowers. Light: 6 hours direct sun. Water: every 14 to 21 days. Temperature: 60 to 80 degrees Fahrenheit. Soil: standard succulent mix. Kalanchoes require 14 hours of darkness per night for 6 to 8 weeks to initiate flower buds. In a typical home with artificial lighting, this photoperiod does not occur naturally. Place the plant in a dark closet from 6 PM to 8 AM for 8 weeks starting in October to trigger flowering for the holiday season.

12. Kalanchoe tomentosa (Panda Plant)

Shrub to 24 inches, fuzzy gray-green leaves with brown toothed edges. Light: 6 hours direct sun. Water: every 14 to 21 days. Temperature: 60 to 80 degrees Fahrenheit. Soil: standard succulent mix. The fuzzy leaf coating (tomentum) repels water and traps a layer of still air that insulates the leaf surface. Do not mist this plant. Water droplets that sit on the fuzzy leaves promote fungal spotting.

13. Graptopetalum paraguayense (Ghost Plant)

Trailing rosettes to 6 inches, silvery-lavender leaves. Light: 6 hours direct sun. Water: every 10 to 14 days. Temperature: 45 to 85 degrees Fahrenheit. Soil: standard succulent mix. Ghost plant changes color dramatically in response to stress: silvery-lavender in moderate light, pinkish-purple in bright sun or cool temperatures, and blue-gray in shade. The trailing stems root where they contact soil, making it easy to propagate from cuttings.

14. Sedum morganianum (Burro's Tail)

Trailing stems to 36 inches, plump blue-green leaves. Light: 6 hours direct sun. Water: every 14 to 21 days. Temperature: 55 to 80 degrees Fahrenheit. Soil: standard succulent mix. The leaves detach easily when the stems are bumped or brushed. Handle this plant only when necessary. Broken leaves root readily when placed on top of moist soil, producing new plants within 3 to 4 weeks. Do not mist the trailing stems. Water only at the soil surface.

15. Sedum rubrotinctum (Jelly Bean Plant)

Trailing stems to 12 inches, bean-shaped green leaves that turn red in bright sun. Light: 6 hours direct sun. Water: every 14 to 21 days. Temperature: 45 to 80 degrees Fahrenheit. Soil: standard succulent mix. The color change from green to red is a stress response triggered by UV exposure. Maximum color develops with 6 to 8 hours of direct sun. In low light, the leaves remain green and the stems stretch.

16. Lithops (Living Stones)

Paired leaves to 1 inch tall, gray-brown with patterned surface. Light: 4 to 6 hours direct sun. Water: every 21 to 35 days in summer (active growth). Do not water from November through March (dormant period when the old leaves are splitting to reveal new leaves). Temperature: 55 to 80 degrees Fahrenheit. Soil: gritty mix (80 percent mineral, 20 percent organic). Watering during the November to March dormancy period causes the new leaves to burst through the old leaf pair prematurely, producing a deformed plant that often dies. This is the most common mistake with Lithops.

17. Gasteria 'Little Warty'

Rosette to 6 inches, dark green bumpy leaves with white spots. Light: 4 to 6 hours, tolerates lower light than most succulents. Water: every 14 to 21 days. Temperature: 55 to 80 degrees Fahrenheit. Soil: standard succulent mix. Gasterias are closely related to Aloe and share the same preference for bright indirect light with some direct sun. They are summer-dormant and grow most actively from fall through spring.

18. Senecio rowleyanus (String of Pearls)

Trailing stems to 36 inches, spherical green leaves like peas on a string. Light: 6 hours direct sun or 12 hours under a grow light. Water: every 14 to 21 days. Temperature: 60 to 80 degrees Fahrenheit. Soil: gritty mix. String of Pearls requires more light than most trailing succulents and etiolates rapidly in low light. Water only when the pearls begin to look slightly deflated and wrinkled. Plump, turgid pearls indicate the plant has adequate water. The stems root where they contact soil, making propagation straightforward.

19. Senecio herreianus (String of Beads)

Trailing stems to 24 inches, larger oval beads than String of Pearls with a translucent stripe. Light: 6 hours direct sun. Water: every 14 to 21 days. Temperature: 60 to 80 degrees Fahrenheit. Soil: gritty mix. Care is identical to String of Pearls. This species is slightly more tolerant of underwatering and slightly less tolerant of overwatering.

20. Portulacaria afra (Elephant Bush)

Shrub to 72 inches indoors (can be pruned to any size), small round green leaves on red stems. Light: 6 hours direct sun. Water: every 14 to 21 days. Temperature: 50 to 85 degrees Fahrenheit. Soil: standard succulent mix. Elephant bush is one of the fastest-growing succulents, adding 6 to 12 inches of new growth per year. Prune to maintain shape. The cuttings root in moist soil within 2 to 3 weeks. This species is used as livestock fodder in its native South Africa (hence the common name) and is non-toxic to dogs and cats.

21. Peperomia obtusifolia

Upright to 12 inches, thick glossy dark green leaves. Light: 4 to 6 hours, tolerates lower light. Water: every 10 to 14 days. Temperature: 60 to 80 degrees Fahrenheit. Soil: standard succulent mix. Peperomias are semi-succulent, meaning their water storage is less developed than true desert succulents. They tolerate slightly more frequent watering than most succulents but still require excellent drainage. The leaves droop visibly when the plant needs water, providing a reliable watering indicator.

22. Sansevieria trifasciata (Snake Plant)

Upright to 36 inches, stiff sword-shaped leaves with yellow margins. Light: any light level from low indirect to full sun. Water: every 21 to 35 days. Temperature: 55 to 85 degrees Fahrenheit. Soil: standard succulent mix. Snake plants are the most tolerant of all succulents for indoor conditions. They survive in low light (though they grow slowly), tolerate irregular watering, and purify indoor air by removing formaldehyde, benzene, and trichloroethylene according to NASA Clean Air Study research. They are toxic to cats and dogs if ingested, causing nausea and vomiting.

23. Sansevieria 'Hahnii' (Bird's Nest Sansevieria)

Rosette to 6 inches, short V-shaped leaves in a nest-like arrangement. Light: 4 to 6 hours. Water: every 14 to 21 days. Temperature: 55 to 85 degrees Fahrenheit. Soil: standard succulent mix. Same care as the standard snake plant. The compact rosette form makes it suitable for desk planters and small containers.

24. Cotyledon tomentosa (Bear's Paw)

Shrub to 12 inches, fuzzy green leaves with reddish teeth resembling bear claws. Light: 6 hours direct sun. Water: every 14 to 21 days in spring and fall. Every 21 to 28 days in summer (slightly dormant). Every 28 to 35 days in winter. Temperature: 50 to 75 degrees Fahrenheit. Soil: standard succulent mix. The fuzzy leaves are sensitive to water sitting on the surface. Water at the soil base, not overhead. The red teeth color intensifies in bright sun and cool temperatures.

25. Pachyphytum oviferum (Moonstones)

Rosette to 4 inches, plump rounded lavender-pink leaves with a powdery coating. Light: 6 hours direct sun. Water: every 14 to 21 days. Temperature: 50 to 80 degrees Fahrenheit. Soil: gritty mix. The powdery coating (farina) is a UV-protective wax that is easily marred by fingerprints. Handle by the roots or the base of the rosette, not the leaves. Once the farina is rubbed off, it does not regenerate on the affected area. The leaves detach easily from the stem; propagate fallen leaves by placing them on dry soil. New plantlets emerge from the leaf base in 3 to 6 weeks.

Diagnosing the 6 Most Common Indoor Succulent Problems

Every symptom below has a specific cause. Match the symptom to the cause and apply the corrective action. Do not guess. Guessing leads to applying the wrong treatment, which makes the problem worse.

Symptom: Mushy, Translucent Leaves at the Base

Cause: overwatering and root rot. The roots have died from saturated soil, and the lower leaves are absorbing water directly from the soil faster than they can metabolize it, causing the cells to burst. Corrective action: unpot the plant immediately. Cut away all brown, black, or mushy roots with a clean knife. Dust the remaining healthy roots with cinnamon powder (a natural fungicide) or sulfur powder. Let the plant dry bare-root for 24 to 48 hours in a shaded location. Repot in fresh gritty mix. Do not water for 7 to 10 days after repotting to allow the cut roots to callus. Resume watering at half the previous frequency.

Symptom: Shrinking, Wrinkled Leaves

Cause: underwatering or root loss from overwatering. If the soil is bone-dry and the plant has not been watered in 3 or more weeks, underwatering is the cause. Water thoroughly and the leaves will plump within 24 to 48 hours. If the soil is moist and the leaves are still wrinkled, the roots have rotted from overwatering and can no longer absorb water. Follow the root rot corrective action above.

Symptom: White Cottony Masses in Leaf Axils

Cause: mealybugs (Pseudococcus longispinus). These 2 to 4 millimeter insects suck sap from the plant and secrete honeydew, which promotes sooty mold growth. Treat by dabbing each visible insect with a cotton swab dipped in 70 percent isopropyl alcohol. The alcohol dissolves the waxy coating that protects the insect, killing it on contact. Repeat every 5 to 7 days for 3 weeks to catch newly hatched nymphs. For severe infestations, spray the entire plant with a solution of 1 teaspoon of neem oil and 1 teaspoon of liquid dish soap per quart of water. Apply the spray every 7 days for 3 weeks.

Symptom: Brown, Crispy Leaf Tips

Cause: sunburn or extreme temperature fluctuation. If the brown tips are on the side of the plant facing the window, sunburn is the cause. Move the plant 12 to 18 inches back from the window or add a sheer curtain to filter the light. If the brown tips appear after moving the plant from a cool room to a warm one (or vice versa), temperature stress is the cause. Acclimate plants to temperature changes gradually over 3 to 5 days. Brown tips do not recover. The plant will shed the damaged leaves naturally over 2 to 4 weeks.

Symptom: Stretching with Wide Gaps Between Leaves

Cause: insufficient light. The plant is producing elongated growth to reach the nearest light source. Move the plant to a brighter location or add a grow light. If the stretched stem is unsightly, behead the plant by cutting the stem 1 to 2 inches below the rosette with a clean knife. Let the cutting dry for 2 to 3 days, then place it on dry soil. It will root in 2 to 4 weeks. The remaining stem will produce 2 to 4 new rosettes from dormant buds at the leaf scars.

Symptom: White Fluffy Substance on Soil Surface

Cause: saprophytic soil fungus or mold growing on organic matter in the soil mix. This is harmless to the plant but indicates the soil is staying too moist for too long. Scrape off the moldy layer and replace it with fresh gritty top dressing. Reduce watering frequency. Improve airflow around the pot by moving it away from other plants or adding a small fan nearby. If the mold returns after reducing watering, repot the plant in a grittier soil mix with less organic content.
