Planting & Maintenance
NOTE: SPACE EACH FORSYTHIA 4-6' APART TO CREATE A HEDGE
Before you plant - Take Note! This plant has deep spreading roots that can be considered invasive and damaging if planted near water lines, sewer lines or septic tank fields. Avoid these areas.
This may be planted in both the Spring & Fall.
1. Dig the hole at least 2x's larger than the root ball and add compost to the planting hole.
2. Then add a little water to the hole and then place the plant into the hole.
3. Fill hole with soil, tamp down gently but firmly.
4. Water in the plant.
5. Add a 2" deep layer of mulch around the plant, making sure that the mulch is at least 2" from the plants trunk to prevent rotting it. Mulch helps retain moisture, keep the roots cool on hot days, and keep down weeds.
Watering: Water 1-2” weekly.
Pruning: Prune the branches in the spring. Forsythia flowers bloom on old wood produced the previous growing season, so it is best to prune in the spring. If you prune in the fall, you will cut off next spring’s growth.
Pests/Treatment: Forsythia shrubs can be prone to knobby galls forming along the stems, as well as fungal twig blights. Both problems are best treated by removing affected stems. Twig blights can be prevented by keeping the plant well pruned to improve air circulation, and by applying a fungicide.
