Everything it needs
9 essentials at a glance
Watering
Davidson's Plum prefers consistently moist soil, so water regularly, allowing the top inch of soil to dry out between waterings.
In warmer months, this may mean watering every 1-2 weeks, while in cooler months, reduce frequency to every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering can cause wilting and leaf drop.
Light
This plant thrives in partial shade to full sun, ideally receiving 4-6 hours of direct sunlight daily.
It can tolerate some shade, especially in hotter climates, but too much shade may hinder fruit production. Ideal placement includes a spot that gets morning sun and afternoon shade.
Soil
Davidson's Plum prefers well-draining, loamy soil with a pH range of 5.5 to 7.0.
A mix of peat, compost, and perlite can create an ideal potting mix. Ensure good drainage to prevent root rot, as this plant does not tolerate soggy conditions.
Humidity
This plant enjoys moderate to high humidity levels, ideally around 50-70%.
To increase humidity, consider misting the leaves, using a pebble tray with water, or placing a humidifier nearby. Signs of low humidity include browning leaf tips and leaf drop.
Temperature
Davidson's Plum thrives in temperatures between 60-80°F (15-27°C) and is hardy in zones 9-11.
It can tolerate brief periods of cold down to 30°F (-1°C) but should be protected from frost. During extreme heat, ensure adequate watering to prevent stress.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 during the growing season, applying every 4-6 weeks.
In fall and winter, reduce or stop fertilizing as the plant enters dormancy. Signs of nutrient deficiency include yellowing leaves, poor growth, and reduced fruit production.
Pruning
Prune Davidson's Plum in late winter or early spring before new growth begins.
Use clean, sharp pruning shears to remove dead or damaged branches and to shape the plant. Deadheading spent flowers can encourage more blooms and fruit production.
Repotting
Repot every 2-3 years or when the roots outgrow the current pot.
Signs it needs repotting include roots growing out of the drainage holes or stunted growth. Choose a pot 1-2 inches larger in diameter, and gently loosen the roots before placing it in fresh potting mix.
Propagation
Propagation can be achieved through seeds or semi-hardwood cuttings.
For seeds, collect ripe fruit, extract seeds, and plant them in a seed-starting mix, keeping them moist until germination, which can take several weeks. For cuttings, take 4-6 inch sections from healthy stems in late summer, dip in rooting hormone, and plant in a well-draining mix, keeping them humid until roots develop.
When it's unhappy
Yellow leaves
Why it happens
Often caused by over-watering or nutrient deficiency.
How to fix it
Check soil moisture levels and adjust watering accordingly. Fertilize with a balanced fertilizer if nutrient deficiency is suspected.
Root rot
Why it happens
Caused by overly wet soil conditions.
How to fix it
Ensure proper drainage and reduce watering frequency. If root rot is severe, consider repotting into fresh, dry soil.
Wilting leaves
Why it happens
Typically a sign of under-watering or extreme heat.
How to fix it
Increase watering frequency and ensure the plant is not exposed to excessive heat without adequate moisture.
Browning leaf tips
Why it happens
Usually due to low humidity or over-fertilization.
How to fix it
Increase humidity around the plant and reduce fertilizer application to prevent nutrient burn.
Poor fruit production
Why it happens
Can be caused by insufficient sunlight or nutrient deficiency.
How to fix it
Ensure the plant receives adequate sunlight and fertilize appropriately to encourage fruiting.
Care through the year
Spring
In spring, prune any dead or damaged branches and begin fertilizing every 4-6 weeks to support new growth.
Summer
During summer, ensure consistent watering and provide some afternoon shade if temperatures soar to prevent leaf scorch.
Fall
In fall, reduce watering as the plant prepares for dormancy and stop fertilizing to allow it to rest.
Winter
In winter, protect the plant from frost and cold drafts, and reduce watering frequency as the plant enters dormancy.
Toxicity & Safety
Davidson's Plum is non-toxic to pets and children. However, the fruit should be consumed in moderation as excessive intake may cause digestive upset.
