Forsythia, a symbol of spring’s arrival, can leave gardeners perplexed when they fail to bloom. Here’s why your ornamentals forsythia not bloom and how to fix it:
1. Pruning Blunder: Forsythia bloom on old wood. Pruning in late spring or summer snips off next year’s flower buds. Instead, prune after blooming to encourage new growth for future blooms.
2. Nitrogen Overdose: Excess nitrogen boosts leafy growth at the expense of blooms. Use a balanced fertilizer with reduced nitrogen and ample phosphorus and potassium.
3. Thirsty Roots: Forsythia thrives in moist but well-drained soil. Water regularly, especially during dry spells.
4. Shady Spot: Forsythia needs at least six hours of direct sunlight daily to produce abundant blooms. If your plant is shaded, consider moving it to a sunnier location.
5. Old Age: Older plants tend to produce fewer flowers. If your forsythia is aging, it may be time to replace it with a younger plant.
6. Winter Woes: Late freezes can damage flower buds. Protect your forsythia with burlap or frost cloth during cold snaps.
7. Pests and Diseases: Aphids and powdery mildew can hamper blooming. Treat promptly with appropriate insecticides or fungicides.
8. Buried Crown: The crown, where roots meet stems, should be exposed. If it’s buried, dig away excess soil to promote proper growth and flowering.
9. Premature Bloom: Flowers that open too early may be damaged by frost. Delay blooming by planting late-blooming varieties.
10. Lack of Deadheading: Deadheading spent flowers prevents seed production, which can divert energy away from blooming. Remove faded blooms regularly.
Remember: Patience is key. It may take a season or two for your ornamentals forsythia to recover and bloom profusely.
