Leaves are simple or trifoliate (3 leaflets) borne in opposite phyllotaxy. Bright yellow flowers bloom in the spring. Hence, this bush is widely grown in parks and yards.
Growth and Care
Based on your garden plans, select a suitable bush cultivar. While some varieties grow mere 1-2 feet in height, others can grow more than 8 feet. Most species are hardy within USDA zones 4-9. Hence, hardiness is not a prime concern while choosing a cultivar. Take into account the plant's height, flower color, and flower size when selecting a bush.
The best method to propagate forsythia is cutting the stem. Commercial propagation is done as soon as flowering period is over in late spring and continues till early summer. Another way is by putting a weight over the branches and forcing them to touch the ground soil. With time, the lower boughs develop roots, after which cutting and transplanting is done.
Forsythia thrives well in full sun, though it can bear partial shade. Soil should be rich and well-drained for healthy growth. You can supplement garden soil with peat moss and farmyard compost to restore plant nutrients. You can use forsythia for mass plantation, shrub borders, and screening purposes. Any way, the bush will liven up your yard with blossoms.
Even though the forsythia is adaptable to highly polluted and less hospitable areas, providing optimal growth conditions is best for timely flowering. The watering schedule is not specific. You can irrigate the bush whenever the top soil dries out.
Applying an all-purpose liquid fertilizer in mid-February will bring about heavy blooms. Though the bush is resistant to most pests, weevils, bugs, fungus, and aphids may infest the plants when they are exposed to prolonged stress conditions.
It is to be borne in mind that flowers bloom in the last stage of growth, prior to development of leaves. So best time for pruning is when the blooms start fading in color. Mark the lower branches (about 4 inches from the ground) and diseased twigs to be pruned down. Removing one-fourth of old branches is sufficient to promote healthy growth of the bush.
Similar to other shrubs and bushes, pruning is a basic routine for healthy forsythia bushes. Being one of the earliest spring-flowering plants, your forsythia plant will bear spectacular blossoms as soon as spring arrives. Hobbyists often practice the technique of inducing flowers by the end of winter.
