Hydrangeas in Tennessee generally benefit from morning sun and afternoon shade. You should protect them from the intense heat, especially in summer. A slightly acidic soil is ideal. Ensure good drainage to avoid root rot. Consistent moisture during the first growing season.
Hydrangeas usually bloom in the early summer. These flowers will reach their peak from June to September. Some varieties only bloom once per growing season. Others bloom continuously throughout the summer.
Advantages: Hydrangeas will establish strong root systems before summer. This reduces the stress on the plants and increases the likelihood of survival.
Ideal Conditions: You should plant hydrangeas in Tennessee after the last frost. This is typically around late March to early April. Choose a location with well-draining soil and morning sun. The gentle rays will dry dew and prevent diseases.
Prepare the soil before growing hydrangeas in Tennessee. Mixing in organic matter for added nutrients and moisture retention. Water generously for the first few weeks to help roots settle.
Recommended Cultivars: Annabelle boasts large, round flowers that turn green as they age. Endless Summer provides the unique opportunity to enjoy blooms on both old and new wood. This gives you a more extended flowering season.
Advantages: Timed correctly, fall planting allows hydrangeas to continue to develop strong roots without the threat of drought. The cooling temperatures prompt the plant to focus on developing a root system. This is vital for winter hardiness and vigorous growth in the next growing season.
Ideal Conditions: In Tennessee, fall planting is best after the first frost. This is usually in mid to late October. When planting in the fall, the native soil is still relatively warm. This can promote root growth.
Recommended Cultivars: You can choose Pee Gee and Tardiva for fall planting. These varieties produce large, elongated flower clusters. These can turn pink and then bronze as the season progresses.
Ensure the soil is well-draining with a pH 5.5-6.5. Hydrangeas love dappled sunlight. So choose a spot with some morning sun and shaded in the harsh afternoon. Your plants will produce an abundance of colorful blooms.
Be sure to space your hydrangeas correctly. This is typically 3 to 10 feet apart, depending on the variety. The space allows for their mature size without overcrowding.
Make sure the hole is twice as wide as the root ball. The depth is the same. The top of the root ball should be level with the surrounding soil. Backfill with the amended soil. Gently tamping it down to remove air pockets.
Gently remove the plant from its container. Loosen any encircling roots before placing it in the prepared hole. Water your newly planted hydrangeas thoroughly. This provides the moisture and helps the soil settle.
Hydrangeas are thirsty. So regular watering, especially in hot and humid summers. You should provide an inch of water per week.
Feed in early spring before new growth begins. You can use a balanced and slow-release fertilizer. A second feeding in late spring can help promote healthy foliage and robust blooms.
Mulching can retain soil moisture and keep weeds at bay. Keep the mulch away from the stem. This can prevent rot.
Extreme temperatures are tough on new hydrangeas. Cover your plants with frost cloth can protect them from frost. Make sure they don't parch in summer. Adding mulch to retain the precious moisture.
Transplant shock is a stress response to the plant's new environment. To help your hydrangea cope, water generously but avoid overwatering. Also, prune any damaged or wilted foliage. This reduces the demand on the limited root system's resources.
Regular soil testing will detect any pH drift. You can make amendments as needed. Soil pH impacts bloom color in some varieties. Lower pH resulting in blue flowers and higher pH for pink.
Inspect regularly for any signs of trouble. For example, holes in leaves or wilting without reason. You should choose a mildew-resistant variety.
Understand the specific pruning needs of your hydrangea variety. Pruning after the plant has finished blooming. This is the best time for most varieties. You can also prune in early spring.
