Care Guide

Leionema is a relatively easy plant to care for, but it does require some attention to ensure it grows and thrives as it should. Here are some tips to help you care for your Leionema:

• Water: Leionema prefers well-drained soil that is kept consistently moist. Water your plant regularly, but do not let it sit in standing water.
• Fertilization: Feed your Leionema with a balanced fertilizer once a month during the growing season (spring and summer).
• Soil: Leionema prefers well-drained, slightly acidic soil. If your soil is heavy, amend it with compost or perlite to improve drainage.

Common Pests & Diseases

Leionema is generally a healthy plant, but it can be susceptible to certain pests and diseases. Here are some common issues to look out for:

• Aphids: These small insects can suck the sap from your Leionema and cause the leaves to curl and distort.
• Spider mites: These tiny pests can also damage your Leionema by feeding on the leaves and causing them to turn yellow and fall off.
• Root rot: Overwatering or poorly-drained soil can cause root rot, which can be fatal to your Leionema.
