Everything it needs
9 essentials at a glance
Watering
Clerodendrum smithianum prefers consistently moist soil but should not be waterlogged.
Water when the top inch of soil feels dry, typically every 5-7 days in warmer months and less frequently in winter. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and leaf drop.
Light
This plant thrives in bright, indirect light but can tolerate partial shade.
Ideally, it should receive 6-8 hours of light daily, with some morning sun being beneficial. Too much direct sunlight can scorch the leaves, while too little light may hinder growth.
Soil
A well-draining potting mix is ideal, with a pH range of 6.0-7.0.
A mix of peat, perlite, and compost works well to ensure proper drainage and aeration. Avoid heavy soils that retain too much moisture.
Humidity
Clerodendrum smithianum prefers high humidity levels, ideally between 50-70%.
To increase humidity, mist the leaves regularly or place a humidity tray filled with water and pebbles beneath the pot. Signs of humidity stress include browning leaf tips and edges.
Temperature
The ideal temperature range for this plant is 65-80°F (18-27°C).
It is best suited for USDA hardiness zones 10-12. Protect it from temperatures below 50°F (10°C) as it is sensitive to cold drafts.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 10-10-10 every 4-6 weeks during the growing season.
Reduce feeding in fall and winter when growth slows. Signs of nutrient deficiency include yellowing leaves, stunted growth, and poor flowering.
Pruning
Prune Clerodendrum smithianum in late winter or early spring to encourage bushier growth and remove any dead or damaged stems.
Use clean, sharp pruning shears for best results. Deadheading spent flowers can promote further blooming.
Repotting
Repot every 1-2 years or when the roots outgrow the pot, typically in spring.
Choose a pot that is 1-2 inches larger in diameter. Signs that it needs repotting include roots growing out of the drainage holes and stunted growth. Carefully remove the plant from its pot, loosen any tightly bound roots, and place it in fresh potting mix.
Propagation
Propagation can be done through stem cuttings or seeds.
For stem cuttings, take 4-6 inch cuttings from healthy stems, remove lower leaves, and place them in a moist potting mix. Keep the cuttings in a warm, humid environment until roots develop, typically within 4-6 weeks. Spring is the best time for propagation.
When it's unhappy
Yellow leaves
Why it happens
This can be caused by over-watering or nutrient deficiency.
How to fix it
Check the soil moisture and adjust watering accordingly. Fertilize if nutrient deficiency is suspected.
Wilting leaves
Why it happens
Under-watering or extreme heat can lead to wilting.
How to fix it
Ensure consistent watering and check for adequate humidity levels.
Browning leaf tips
Why it happens
Low humidity or over-fertilization can cause leaf tip burn.
How to fix it
Increase humidity by misting or using a humidity tray, and reduce fertilizer application.
Root rot
Why it happens
Over-watering or poorly draining soil can lead to root rot.
How to fix it
Allow the soil to dry out between waterings and ensure the pot has proper drainage.
Pest infestations (e.g., aphids, spider mites)
Why it happens
Pests can be attracted to stressed plants or low humidity.
How to fix it
Inspect regularly and treat with insecticidal soap or neem oil as needed.
Care through the year
Spring
In spring, increase watering as the plant begins to actively grow. Fertilize every 4-6 weeks to support new growth.
Summer
During summer, maintain consistent moisture and humidity levels. Monitor for pests and provide support if the plant becomes top-heavy.
Fall
In fall, gradually reduce watering as growth slows. Continue fertilizing until late fall, then stop for the winter.
Winter
In winter, keep the plant in a warm location and reduce watering. Ensure it receives adequate light to prevent leggy growth.
