Middendorf weigela Weigela middendorffiana

Water

Middendorff weigela prefers evenly moist soil, so it's important to water the plant deeply to encourage root growth. During the first growing season, water the plant regularly to establish a strong root system, which usually translates to about once a week. Depending on the weather, this may mean providing approximately 1-2 gallons of water each week. After establishment, the plant is somewhat drought tolerant but should still be watered whenever the top inch of soil feels dry to the touch, usually reducing watering frequency to every other week. Ensure good drainage to prevent waterlogging, which can lead to root rot.

Light

Middendorff weigela thrives in full sun to partial shade conditions. Full sun is ideal and promotes the most abundant blooms; this means at least 6 hours of direct sunlight daily. However, the plant can also tolerate and do quite well in partial shade, especially in areas with very hot afternoon sun. Avoid deep shade as this will reduce flowering and can cause the plant to become leggy. Position the plant in a spot where it will receive the necessary sunlight throughout the day for optimal growth.

Temperature

Middendorff weigela is hardy and can withstand a range of temperature conditions. The plant is suited for USDA hardiness zones 4 through 8, which means it can handle minimum temperatures down to -30 to -20 degrees Fahrenheit. Ideal growing temperatures for the plant are between 60 and 75 degrees Fahrenheit, which encourages healthy growth and blooming. During hot summer days, middendorff weigela can tolerate temperatures up into the high 80s, but prolonged heat may stress the plant.

Pruning

Prune middendorff weigela to maintain its shape and encourage healthy growth after it has finished blooming, usually in late spring or early summer. Pruning helps remove dead or crossed branches, promotes air circulation, and encourages new blooms for the following season. Cut back about one-third of the oldest stems to ground level each year, which stimulates new growth. It is best to avoid heavy pruning late in the season, as this can cut off next year's flower buds.

Cleaning

As needed

Soil

Weigela, known as Weigela middendorffiana, thrives best in a soil mix that is rich in organic matter, well-draining, and has a slightly acidic to neutral pH of around 5.5 to 7.0. A good soil recipe would be a blend of loamy garden soil, compost, and a small amount of sand or perlite to improve drainage.

Repotting

Weigela (Weigela middendorffiana) should generally be repotted every 2 to 3 years to ensure it has enough room for root growth and access to fresh nutrients. However, mature weigelas are typically planted outdoors and may not require repotting if they have sufficient space.

Humidity & Misting

Weigela (Weigela middendorffiana) prefers average humidity levels found in a typical outdoor garden environment. It does not require excessively high humidity and can tolerate the humidity levels commonly found in temperate regions.

Suitable locations

• Indoor

  Provide ample light and do not overwater Weigela indoors.

• Outdoor

  Plant in well-draining soil; full sun to partial shade.

• Hardiness zone

  4-8 USDA

Life cycle

Weigela middendorffiana, commonly known as Middendorf Weigela, begins its life cycle when seeds germinate, typically in the spring, after overwintering in the soil. Seedlings emerge and establish a root system, followed by shoots that grow into young plants. As the Weigela middendorffiana matures, it develops sturdy stems and a bushy form, displaying its characteristic lance-shaped leaves. This deciduous shrub enters a phase of rapid vegetative growth each spring, and in late spring to early summer, it produces clusters of bell-shaped yellow to yellow-orange flowers that are attractive to bees, butterflies, and other pollinators. After pollination, the flowers develop into capsule-like fruits that contain small winged seeds, which are dispersed by wind, expanding the plant's range. The plant enters dormancy in the fall, with leaves falling off as it prepares to withstand winter conditions before the cycle begins anew the following spring.

Propogation

  Spring-Early Summer

• Weigela middendorffiana, commonly known as Weigela, is typically propagated through softwood cuttings in late spring or early summer. To do this, a gardener selects a healthy, new-growth stem and cuts a piece roughly 4 to 6 inches (10 to 15 centimeters) in length, ensuring there are several leaves on the cutting. The lower leaves are removed, and the cut end is often dipped in rooting hormone to encourage root development. This cutting is then placed in a pot with a well-draining soil mix, and the soil is kept moist until roots have established, which can take several weeks. During this time, the cutting should be kept in indirect light and at a consistent temperature to promote growth. Once the cutting has rooted sufficiently, it can be transplanted to its desired location in the garden.
