When to Plant Hydrangeas
The ideal time to plant hydrangeas is early spring or fall. Avoid planting in extreme weather, whether cold or hot. Extreme conditions can suppress their growth.
Where to Plant Hydrangeas
Hydrangeas thrive in areas that receive at least 6 to 8 hours of light per day, whether they are in full sun or partial shade. In USDA zones 3 to 9, limelight hydrangeas prefer well-drained soil and organic compost to be added to poor soil.
How to Plant Hydrangeas
For planting hydrangeas, first dig a hole twice as wide and as deep as the root ball. After carefully loosening the roots and removing the plant from the container, plant the shrub in the hole, making sure the top of the root ball is level with the ground.
Fill the hole with soil and water immediately. Apply mulch to retain soil moisture and reduce weed growth.
How to Care for Hydrangeas
Limelight hydrangeas are hardy and drought-tolerant flowering shrubs. They need regular watering during the first growing season. Once a plant is established, the continuous moisture helps it to grow vigorously.
When to Fertilize Hydrangeas
The best time to apply a balanced slow-release fertilizer is in early spring when growth begins. The second dose should be given in the middle of the summer to encourage development. Avoid over-fertilization or applying too late in the growing season; these can encourage foliage growth and reduce flowering.
How to Prune Hydrangeas
Limelight hydrangeas are pruned in late winter or early spring before new growth starts. Concentrate on removing dead wood, crossing branches, diseased parts, and damaged ones to give a shape and encourage healthy growth. To prevent the shrub from becoming stressed, don’t cut off more than one-third of its overall growth.
When do you trim hydrangeas?
Hydrangeas can be trimmed at any point during the growing season to give the shrub shape and to get rid of diseased or dead wood. Trimming too late in the fall promotes the growth of plants that are vulnerable to frost damage the following season.
