How to fertilize forsythia

Forsythias do well without fertilizer and it only takes a little nitrogen to make them skip blooming and produce leaves, so be careful when fertilizing the lawn. You can propagate some of those low-hanging branches by pinning them to the ground for a season, then cutting them from the mother plant.

How often do you fertilize forsythia?

Use a balanced fertilizer once every two to three months in the spring and summer. Do not fertilize them in the fall and winter. Good care of forsythia also requires that forsythia bushes be pruned yearly. Without pruning, these fast growing shrubs can quickly get overgrown.

This type of rejuvenation, which is called thinning, will encourage new branches to form. Thin your forsythia in late fall or early spring before the flowers form.

How do you make forsythia bloom more?

Though somewhat drought tolerant once established, forsythia does best with regular watering.

Take care not to overwater, which can cause root rot or make plants more susceptible to disease.

Can forsythia get too much water?
