Hydrangea Care Guide for Endless Summer Varieties at Lukas Nursery

Introduction

Hydrangeas are a classic favorite for Florida gardens, and the reblooming Endless Summer series offers reliable color and repeat blooms when grown in the right conditions. At Lukas Nursery, you may find Hydrangea 'Endless Summer' Bailmer #1, Hydrangea 'Endless Summer' TwistNShout #3, and Hydrangea 'Endless Summer' BloomStruck #3. These hydrangeas bloom on both old and new wood, which helps extend the flowering season and improves performance after pruning or winter damage. They are considered moderate in difficulty in Florida because they need extra attention to moisture, shade, and soil quality in our heat and humidity.

Growing conditions

Light: Plant in morning sun with afternoon shade, or bright filtered shade. In Central and North Florida, they can take a little more sun if soil moisture is consistent. In South Florida, protect them from harsh afternoon sun and reflected heat.

Water: Keep soil evenly moist, especially during establishment and hot weather. Water deeply when the top inch of soil begins to dry, and avoid letting the plant wilt repeatedly. Mulch helps conserve moisture and keep roots cooler.

Soil: Use rich, well-drained soil with plenty of organic matter. Hydrangeas prefer slightly acidic soil, but Florida soils often need improvement with compost and mulch to hold moisture and support healthy growth.

Fertilizer: Feed lightly in spring and again in early summer with a balanced, slow-release fertilizer formulated for flowering shrubs. Avoid overfertilizing, which can cause lush leaves with fewer blooms.

Season: These reblooming hydrangeas typically flower from late spring through summer and may continue into fall with good care and cooler weather. In Florida, bloom performance is best when plants are protected from heat stress and drought.

Planting tips

Spacing: Space plants about 3 to 5 feet apart, depending on the mature size of the variety and the look you want in the landscape. Allow extra room for air circulation in humid Florida conditions.

Depth: Plant at the same depth the hydrangea was growing in its container. Do not bury the crown. Water thoroughly after planting and add 2 to 3 inches of mulch around the base, keeping mulch away from the stems.

Location: Choose a site with morning sun, afternoon shade, and protection from hot, drying winds. Near a porch, under light tree cover, or on the east side of a home are often good Florida locations.

Container suitability: These hydrangeas can be grown in large containers if the pot drains well and the soil stays consistently moist. Container plants dry out faster in Florida heat, so they need more frequent watering and monitoring.

Bloom season: Endless Summer hydrangeas are rebloomers, so they can flower on both old and new wood. This makes them a strong choice for gardeners who want more dependable color across the season.

Troubleshooting

1. Leaves wilt in the afternoon

Fix: This is often caused by heat stress or dry soil. Water deeply in the morning, add mulch, and move container plants to a shadier spot if needed. If the plant receives too much hot afternoon sun, consider transplanting it to a cooler location.

2. Few or no blooms

Fix: Check for too much shade, too much nitrogen, or pruning at the wrong time. These hydrangeas bloom on old and new wood, so light pruning is best. Remove only dead stems and spent flowers, and avoid heavy pruning in late summer or fall.

3. Yellowing leaves

Fix: Yellow leaves may point to poor drainage, overwatering, or nutrient imbalance. Make sure the soil drains well, reduce watering if the root zone stays soggy, and apply a balanced fertilizer if the plant appears pale overall. In alkaline soils, iron deficiency may also contribute to yellowing.

Pet safety

Hydrangeas are considered toxic to pets if ingested. Keep Hydrangea 'Endless Summer' varieties out of reach of dogs and cats, and contact a veterinarian if your pet chews on the leaves, flowers, or stems.
