General Care Tips for Hydrangeas
To ensure your hydrangeas thrive and produce abundant blooms, follow these general care guidelines:
Watering: These plants crave water, especially during hot summers and dry spells. Their soil should be evenly moist but not too wet; to prevent waterlogging and root rot.
Soil Conditions: Plant in well-draining soil rich in organic matter to promote healthy and sustainable growth. Improve drainage and fertility by adding compost or manure to the soil.
Sunlight: Hydrangeas prefer morning sun and afternoon shade or dappled sunlight. Too much direct sunlight can cause leaves and blooms to wilt or burn, while limited sunlight can reduce blooming.
Pruning: This all depends on the type of hydrangea. For varieties that bloom on old wood, (last year’s growth), Bigleaf, Climbing, Mountain, and Oakleaf, lightly prune them after flowering to shape them and remove any dead or damaged wood. For varieties like Panicle and Smooth varieties that bloom on new wood from the current year’s growth, prune them back more aggressively in late winter or early spring.
Fertilizing: Hydrangeas benefit from fertilizer to support healthy growth and abundant blooms. Use a balanced slow-release fertilizer in spring or early summer and avoid over-fertilizing. Too much nitrogen can result in more foliage rather than flowers.
