forsythia

Forsythia plants should be deeply watered twice a week when temperature and soil conditions are dry. Water slowly and deeply to allow the water to penetrate 6-8 inches into the soil. Once established, water once a week during times of drought, preferably in the morning. Check for moisture in the top several inches of soil and water if the soil is dry. Avoid overwatering, since this can cause the roots to rot.

Forsythia (Forsythia intermedia 'Gold Leaf') require a minimum of 5 hours of direct sunlight per day to thrive. For best growth and flowering, it should receive as much as 6 or 8 hours of direct sunlight each day. If possible, the sun should be provided from mid-morning to mid-afternoon, with some shade during the hottest part of the day being beneficial. On days with extreme heat, it may be beneficial to provide some protection in the form of a shade cloth or awning. Ensure that your Forsythia is not placed in an area that will receive heavy frost or winds, as these can be damaging to the plant.

Forsythia (Forsythia intermedia 'Gold Leaf') should be pruned lightly immediately after flowering. Pruners should remove dead or damaged branches and thin out weak and overcrowded stems. Cutting back 1/3 of the oldest stems each year will help promote new growth. Light pruning can also be done in late winter to early spring to help shape the plant or remove unneeded stems. It is best to avoid heavy or drastic pruning as this can significantly reduce flowering for the following season.
