How to water during flowering period

Hydrangea is a plant that likes moisture very much, but it cannot be watered too much. If water accumulates in the pot, it will also cause the death of the plant.

Hydrangeas are best watered with rainwater or well water. If you use tap water, you need to wait for more than 12 hours until the chlorine in the water evaporates before watering. In addition, hydrangeas should be watered in the morning or evening, not in the hot sun at noon.

If you want to adjust the color of hydrangea, you can add an appropriate amount of vinegar or baking soda to the water. However, the amount added each time must meet the requirements, and the concentration cannot exceed 10%, otherwise it will easily lead to poor growth or death of the plant.

What fertilizer to apply during flowering period

Hydrangeas like fertilizer, but they are also very sensitive to fertilizer, especially in the bud stage. Our general advice is to pay attention to the use of fertilizer after the hydrangea begins to bloom, and no fertilizer is needed during the flowering period. Fertilizing during the flowering period is prone to fertilizer damage, which will shorten the flowering period.

If we want to fertilize, we can apply some diluted phosphorus and potassium fertilizers. But we need to pay attention to the concentration. Or we can spray 0.2% potassium dihydrogen phosphate solution, which can also promote flowering.

Pruning after flowering

In spring and summer, hydrangeas should be pruned after they have faded. When pruning, find the first pair of full buds below the hydrangeas and cut them off one centimeter above the buds.

Generally, we need to regularly prune dead branches, diseased branches, thin branches, and inward-growing cross branches. Because these are useless branches, this kind of pruning is not seasonal and can be done in all seasons.

Preventing pests and diseases

Hydrangeas are also prone to diseases and pests, such as aphids, scale insects, sooty mold, etc. If the ventilation is poor during the bud stage of hydrangeas, the branches are dense and wet for a long time, it is easy for diseases and pests to break out.
