Weigela Weigela All Summer Red = 'Slingco 1' (PBR)

Water

The Weigela All Summer Red prefers regular watering to maintain evenly moist soil, especially during the hot summer months. Newly planted shrubs require more frequent watering to help establish their root systems, perhaps twice a week. However, once established, the Weigela can tolerate some drought and may only need supplemental watering during prolonged dry spells. Use a soaker hose or drip irrigation to deliver water directly to the base of the plant, focusing on the root zone. Aim to provide about 1 inch of water per week through rainfall or irrigation, which is roughly equivalent to 0.62 gallons per square foot across the rooting area.

Light

The Weigela All Summer Red thrives in full sun to partial shade. It performs best when it receives at least six hours of direct sunlight each day, which encourages prolific blooming and healthy foliage. Partial shade is also acceptable, but too much shade may result in fewer flowers and a less dense plant. A spot that offers morning sunlight with some respite from the intense afternoon heat is ideal for this plant.

Temperature

The Weigela All Summer Red is a hardy shrub that can withstand a range of temperatures. It prefers a temperate climate and can generally survive winter temperatures as low as 5 to -10 degrees Fahrenheit, while its ideal growing conditions range from 60 to 75 degrees Fahrenheit during the growing season. It is tolerant to a maximum temperature around 90 degrees Fahrenheit, but prolonged exposure to extreme heat may stress the plant.

Pruning

Prune the Weigela All Summer Red immediately after flowering, which usually occurs in late spring to early summer. Pruning at this time helps promote new growth and more abundant blooms for the next season. Remove any dead or crossed branches to maintain good air circulation and shape the plant as desired. Periodic thinning of older stems can rejuvenate the plant and improve its overall health and appearance. Avoid late season pruning as it can reduce the number of next year's blooms.

Cleaning

As needed

Soil

Weigela prefers well-draining soil enriched with organic matter, such as compost or peat moss, to retain moisture but avoid waterlogging. A slightly acidic to neutral pH, ranging from 5.5 to 7.0, is ideal for this plant.

Repotting

Weigelas, including the All Summer Red variety, are shrubs that do not typically require frequent repotting. They are often planted directly in the garden and can thrive for years without the need to repot.

Humidity & Misting

Weigela All Summer Red is tolerant of a wide range of humidity levels and does not require specific humidity conditions to grow well, making it versatile and suitable for various outdoor climates.

Suitable locations

• Indoor

  Indoors, provide Weigela with bright light and cool temperatures.

• Outdoor

  Plant Weigela in full sun to part shade and well-draining soil.

• Hardiness zone

  4-8 USDA

Life cycle

The Weigela All Summer Red, commonly known simply as Weigela, begins its life cycle as a seed, which, when sown in well-drained soil and given proper warmth and moisture, will germinate and sprout. The seedling then grows into a young plant with leafy shoots, developing a root system and foliage as it becomes more established. As a fast-growing shrub, Weigela enters its vegetative stage, producing dense, green leaves and stems, and will mature in a few years, reaching its full height and spread. It subsequently enters the flowering stage, typically in late spring to early summer, producing a distinctive display of trumpet-shaped, vibrant red flowers that attract pollinators like bees and hummingbirds. After pollination, the flowers may develop into small, inconspicuous fruits containing seeds, completing the sexual reproduction cycle. Finally, in the late stages of its life, the Weigela may experience reduced vigor, and if not properly maintained, can succumb to environmental stresses, pests, or diseases, eventually leading to the plant's death.

Propogation

• Propogation time

  Spring-Early Summer

• Weigela All Summer Red is commonly propagated through softwood cuttings. This technique is ideally performed in late spring to early summer when new growth is mature enough to be firm yet still young and pliable. You take cuttings about 4 to 6 inches (10 to 15 centimeters) long, making sure each cutting has several leaves. The lower leaves are removed, and the cut end is dipped in rooting hormone to enhance root development. The treated cuttings are then planted into a well-draining soil mix, kept moist, and under high humidity. Roots typically begin to form within a few weeks, at which point cuttings can gradually be acclimated to less humid conditions before eventual transplanting.
