watering

Forsythia 'Happy Centennial' should be watered deeply once a week. To ensure the Forsythia is receiving enough water, check in the first few inches of soil to make sure it is damp. Once the soil is dry, provide a thorough deep watering to ensure the Forsythia has access to the moisture it needs for optimal health. By providing regular watering and avoiding over-watering, the Forsythia will remain healthy and happy throughout its growing season.

sunlight

Forsythia 'Happy Centennial' requires at least 6 hours of full sun each day to remain healthy, and will thrive in 8 to 10 hours of sunlight each day. This plant species prefers direct sunlight in the morning and afternoon, and will benefit from some shade in the hottest part of the day. However, too much shade will prevent the plants from producing flowers. When planting this species in hot climates, try to provide afternoon shade from trees or other structures.

pruning

For Forsythia 'Happy Centennial', pruning should take place regularly during the spring and early summer. Start pruning just as the flowers start to drop off the bush. It is best to use pruning shears or small lopping shears for this type of pruning. You will want to take off any dead, diseased, or broken branches, as well as any that are growing in an undesired direction. You should also remove any branches that are growing too close together; this should be done to encourage air circulation and to allow light to reach the entire bush. Finally, prune back some of the older branches to the ground to encourage new growth at the base of the shrub.
