Everything it needs
9 essentials at a glance
Watering
Weigela florida prefers consistently moist soil, especially during its growing season in spring and summer.
Water deeply once a week, allowing the top inch of soil to dry out between waterings. In the fall and winter, reduce watering frequency as the plant enters dormancy. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and leaf drop.
Light
This plant thrives in full sun, requiring at least 6 hours of direct sunlight daily for optimal blooming.
It can tolerate partial shade but may produce fewer flowers. Ideal placement includes a sunny garden bed or border, where it can receive morning sun and some afternoon shade in hotter climates.
Soil
Weigela prefers well-draining soil with a pH range of 6.0 to 7.5.
A mix of loamy soil with organic matter, such as compost, is ideal. Ensure good drainage to prevent waterlogging, which can lead to root rot. A recommended potting mix is a combination of peat, perlite, and garden soil.
Humidity
Weigela florida prefers moderate humidity levels but is quite adaptable.
If grown indoors, increase humidity by misting the leaves or placing a humidifier nearby. Signs of humidity stress include browning leaf edges and leaf drop.
Temperature
This plant thrives in temperatures between 60-75°F (15-24°C) and is hardy in USDA zones 4-8.
It can tolerate cold down to -30°F (-34°C) and is moderately heat tolerant, but extreme temperatures may affect blooming.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 or 20-20-20.
Fertilize in early spring as new growth begins and again in mid-summer. Signs of nutrient deficiency include stunted growth and pale leaves.
Pruning
Prune Weigela in late winter or early spring before new growth begins.
Use sharp, clean pruning shears to remove dead or damaged branches and to shape the plant. Deadheading spent flowers after blooming can encourage additional blooms and maintain a tidy appearance.
Repotting
Repot Weigela every 2-3 years or when it outgrows its pot, typically in spring.
Choose a pot that is 1-2 inches larger in diameter than the current one. Signs it needs repotting include roots growing out of the drainage holes and stunted growth. To repot, gently remove the plant from its pot, loosen any tightly bound roots, and place it in fresh potting mix.
Propagation
Weigela can be propagated through stem cuttings, division, or seeds.
For stem cuttings, take 4-6 inch cuttings in late spring or early summer, remove the lower leaves, and place them in a pot with moist potting mix. Cover with a plastic bag to maintain humidity until roots develop, which usually takes 4-6 weeks. Division is best done in early spring or fall.

Care through the year
Spring
In spring, prune any dead or damaged branches and fertilize as new growth begins. Water regularly to support blooming.
Summer
During summer, ensure consistent watering, especially during dry spells. Deadhead spent flowers to encourage additional blooms.
Fall
In fall, reduce watering as the plant prepares for dormancy. Apply a layer of mulch to protect the roots from freezing temperatures.
Winter
In winter, protect the plant from extreme cold by covering with burlap or mulch. Avoid watering unless the soil is extremely dry.
