How should I plant my Endless Summer Bloomstruck Hydrangea?
Planting your Endless Summer® BloomStruck® Hydrangea properly is the first step to enjoying a season-long display of vibrant blooms. Choose a location that receives morning sun and afternoon shade, especially in warmer climates, to prevent stress and leaf scorch. Begin by digging a hole that is twice as wide and just as deep as the root ball. Place the hydrangea in the hole so that the top of the root ball is level with the surrounding soil. Backfill with a mixture of native soil and compost to improve drainage and fertility, and water thoroughly after planting to eliminate air pockets. For best results, space your BloomStruck® Hydrangeas 3 to 4 feet apart to allow for air circulation and mature growth. Apply a 2–3 inch layer of mulch around the base to conserve moisture and regulate soil temperature, keeping it a few inches away from the stems to prevent rot. These hydrangeas thrive in rich, well-drained soil and benefit from regular watering, especially during dry spells. With proper planting and care, your BloomStruck® will establish quickly and reward you with repeat blooming clusters of pink, blue, or purple flowers, depending on your soil pH.
How should I water my Endless Summer Bloomstruck Hydrangea shrubs?
Watering your Endless Summer® BloomStruck® Hydrangea consistently is key to maintaining its vibrant blooms and lush foliage. During the first growing season, water deeply 2 to 3 times per week to help the roots establish, especially in warm or dry conditions. These hydrangeas prefer moist but well-drained soil, so avoid letting the ground become overly saturated or bone dry. For established plants, continue to water during dry spells, providing about 1 inch of water per week. Early morning watering is best to minimize evaporation and reduce the risk of fungal diseases. To help retain soil moisture and protect the roots, apply a 2–3 inch layer of mulch around the base of your BloomStruck® Hydrangea, keeping it a few inches away from the main stem. In hotter climates or when planted in full sun, you may need to increase the watering frequency slightly, as the large leaves and abundant blooms can lead to higher moisture loss. Container-grown BloomStruck® hydrangeas will also need more frequent watering, often daily during summer. With proper hydration, your hydrangea will thrive, producing repeat blooms in vibrant pink, purple, or blue hues all season long.
How do I fertilize an Endless Summer Bloomstruck Hydrangea shrub?
Fertilizing your Endless Summer® BloomStruck® Hydrangea correctly helps promote vibrant blooms and healthy, vigorous growth throughout the season. In early spring, apply a balanced, slow-release fertilizer such as 10-10-10 or one specifically formulated for flowering shrubs. Spread the fertilizer evenly around the drip line of the plant, avoiding direct contact with the stems, and water thoroughly to activate the nutrients. For even better results, amend the soil with organic compost to improve structure and nutrient availability, especially if your soil is heavy clay or sandy. To enhance bloom color and performance, you can also adjust your fertilization based on your desired flower color. Use a soil acidifier or aluminum sulfate for blue flowers, or garden lime to encourage pink blooms. Reapply fertilizer once more in mid-summer if growth is slow or flower production wanes, but avoid feeding after August to prevent soft, tender growth heading into fall. With the right fertilization routine, your BloomStruck® Hydrangea will reward you with lush foliage and vibrant reblooming flowers from late spring through fall.
How and When should I Prune my Endless Summer Bloomstruck Hydrangea?
Pruning your Endless Summer® BloomStruck® Hydrangea should be done with care, as this variety blooms on both old and new wood, making timing and technique essential. The best time to prune lightly is in late winter or early spring, just as new growth begins to emerge. Remove any dead, damaged, or weak stems, and thin out older canes at the base to encourage fresh, healthy growth. Avoid cutting back all stems aggressively, as this could remove buds formed on old wood, reducing your flower display. A light shaping of the plant can also be done in early summer, but avoid pruning in late summer or fall. To maintain a compact, tidy appearance, you can deadhead spent blooms throughout the season, which encourages new flower formation and keeps the shrub looking fresh. Always use clean, sharp pruning shears and cut just above a pair of healthy buds. Since BloomStruck® is a reblooming hydrangea, proper pruning ensures continuous blooming from late spring through fall. With a gentle, strategic pruning routine, your BloomStruck® Hydrangea will remain full, healthy, and covered in vibrant pink, blue, or purple blooms all season long.
