Planting & Care for Eclipse® Hydrangea
Preparation
- Eclipse® Hydrangeas thrive in partial shade, though they can tolerate more sun in cooler climates. Consider planting in a place with morning sunlight and afternoon shade to protect the blooms from too much heat.
- This plant prefers well-draining, slightly acidic soil. If your soil is heavy or clay-like, mix in organic matter like compost to improve drainage and nutrition.
- The best time to plant is in the spring or early fall. This gives the shrub enough time to establish its roots before the extreme temperatures of summer or winter.
- Space multiple plants about 3-4 feet apart to give them room to grow.
- Hardiness zone 5.
Opening Plant Material
- Container - Completely saturate all container plants by putting in a larger container of water until stops bubbling, then remove the plant from the container.
Planting Containers
- Dig a hole no deeper than the depth of the container and 6" or more wider on the sides.
- Slide plant from pot by tapping on the bottom of the pot.
- With shovel or knife trim bottom 2" off of the root ball for plants in plastic containers.
- Rotate the plant to the proper position. Never lift or move plants by the tops.
- Place the root ball in the hole.
- Adjust the plant height so the root crown is slightly higher than the ground.
- Place fertilizer packets into the bottom of the hole (if purchased). *Use Our Recommended Fertilizer
- Back-fill the hole with soil, making sure the top of the root ball is visible and slightly higher than the soil around it.
- Firm the soil around the plant. Water well to settle soil around the root ball.
- Water frequently when newly planted.
Pruning - After Planting
- Container - Although it is not essential for container plants to be pruned after planting, a light pruning to remove any broken branches during shipment and improve shape will help the looks of your new planting.
Pruning - Throughout the Season
- Eclipse Hydrangeas bloom on old wood, which means they flower on the previous year's growth. To avoid cutting off next season’s blooms, be mindful of when you prune.
- The best time to prune is right after flowering, usually in late summer or early fall. This allows the plant time to set buds for the next year.
- Trim off any spent flowers just above a healthy set of leaves. This helps redirect energy into forming new buds rather than maintaining old blooms.
Watering - After Planting
- Plants typically take approximately 6 weeks to establish new roots in your soil. During this period, water plants as oft en as every 2-4 days at the start and at least a minimum of once per week.
- Beyond the 6 week establishment period, water once per week, unless rains occur.
Watering - Throughout the Season
- After the first season, plants should only be watered during extended periods without rain.
- How do you know if your plants need water? The easiest way to tell is to touch the soil around the roots. If it is moist, there is no need to water. If it is dry, give it a good soaking with the hose end (no nozzle) watering the soil only, not the leaves.
