Overview of Haworthia Cooperi

Haworthia cooperi, also known as Cooper’s haworthia, is a petite succulent hailing from South Africa Here are some key facts about this plant

• It has a low, rounded rosette shape, reaching just 3-5 inches tall and 4 inches wide at maturity

• Tiny white or pinkish-white flowers may emerge on slender stalks during the summer. However, the blooms are fairly insignificant.

• There are many cultivars, including popular varieties like ‘Obtusa’, ‘Pilifera’, ‘Venusta’, and ‘Dielsiana’.

• Hardiness zones 9-11 suit it best, but zone 8 is possible with winter protection.

• With proper care, haworthia cooperi is a low-maintenance plant ideal for beginners. It stays compact enough for dish gardens or desktops.

Choosing the Best Growing Site

When grown outdoors, haworthia cooperi does best in partial shade where it will get 4-6 hours of gentle morning or late afternoon sunlight. Direct hot midday sun can scorch the leaves.

For indoor cultivation, place pots near an east or west-facing window. Use a sheer curtain to filter intense rays. Remember to rotate the plants regularly so all sides receive even lighting.

Well-draining, sandy soil amended with some organic matter keeps roots healthy. Maintain a soil pH between 6-7. Allow the soil to dry out somewhat between waterings.

Watering Needs

Haworthia cooperi stores moisture in its leaves, so it’s better to underwater than overwater these plants. Wait until the top inch of soil is totally dry before watering again. This may mean watering only every 2-3 weeks in winter when growth slows.

In spring and summer, allow the top half of the soil to dry before watering. Always soak the soil thoroughly when you do water, taking care that excess drains away rapidly to prevent rot.

Signs of overwatering include mushy, translucent leaves, leaf drop, foul odors, and rotting stems/roots. Underwatered plants will have shriveled, wrinkled leaves. Adjust your practices if you notice either extreme.

Fertilizer Recommendations

Haworthia cooperi grows slowly and has low nutritional requirements. At most, use a diluted balanced liquid fertilizer every 2-4 weeks during the active growing season. Don’t fertilize at all in fall and winter when dormant.

If leaves redden or look weak and pale, try an organic nitrogen fertilizer to perk them up. But use fertilizer sparingly, as overfeeding causes more issues than underfeeding.

Growing Indoors

The petite size of haworthia cooperi makes it perfect for windowsills and dish gardens. Place near an east or west-facing window for bright indirect sun. Rotate periodically for even coverage.

Use a fast-draining potting mix amended with perlite, orchid bark or pumice. Clay or terra cotta pots allow airflow around the roots.

Room temperatures between 65-80°F suit them best. Avoid cold drafts. The low humidity of most homes won’t bother this drought-resistant succulent.

Propagation

Haworthia cooperi propagates easily from offsets, leaves, or stem cuttings:

• Detach offsets from the base with a sterile knife. Allow to dry 3-5 days before replanting.

• Remove healthy leaves and let callous over 24 hours before placing on moist soil. New plants will sprout.

• Take 3-4 inch stem cuttings in spring. Allow to callous, then plant in sandy soil.

• Sow fresh seeds in a sandy cactus mix. Keep warm (70°F) and moist. Germination takes several weeks.

Potential Pests and Diseases

Haworthia cooperi resists most common succulent pests. Watch for:

• Mealybugs – Treat with alcohol, insecticidal soap

• Spider mites – Apply neem oil or soapy water

• Root rot – Improve drainage, allow soil to dry out

• Leaf spot – Increase air circulation, use fungicides

• Etiolation – Give more sunlight

Encouraging Flowers

Getting haworthia cooperi to bloom indoors is challenging but possible:

• Acclimate to 4-6 hours of direct sun in spring.

• Avoid overwatering which prevents blooms.

• Use a blooming fertilizer in spring.

• Cool overnight temps (55-60°F) mimic winter dormancy.

• Have patience! May take several seasons to flower.
