Hydrangea lovers have an impressive variety of cultivars from which to choose as they design a partly sunny landscape area. A popular variety of the big leaf hydrangeas is the endless summer hydrangea. Many hydrangea enthusiasts are embracing this variety for its hardiness and blossom characteristics. Not only are the blossoms impressively large, but their color depends upon the pH level of your soil. This means that you have the ability to alter the blossom color of an endless summer hydrangea to suit your tastes.
Prepare a growing area for planting in the early autumn or spring. Select an area that receives dappled shade or early morning sun and afternoon shade, because endless summer hydrangeas will suffer under intense sun and heat. Spread the tarp near the digging spot for holding the soil you remove. Use the shovel to dig a hole that is twice as wide and an equal depth as the root system of the hydrangea, placing all the soil directly onto the tarp.
Mix 1 part compost into the soil on the tarp, and mix the two mediums well to combine them.
Remove the endless summer hydrangea from its temporary container and place it directly into the hole. If the hydrangea is a bare root shrub, soak the roots for approximately eight hours prior to planting the shrub to hydrate the roots.
Fill the combined soil and compost back into the hole to cover the roots. Continue adding soil, packing it down firmly with your hands, until the soil is level with the surrounding ground level.
Provide water for the hydrangeas immediately after you finish planting them, saturating the soil completely. Strive to keep the soil evenly moist at all times without allowing the soil to dry between watering.
Fertilize the endless summer hydrangea in early spring, late spring and midsummer. Sprinkle the fertilizer over the soil, using approximately 30 lbs. of fertilizer for each 100 square feet of planting area. Do not allow the fertilizer to contact the plant foliage, and scratch it into the soil with the hand rake after you apply it. Provide a generous watering immediately after fertilizing.
Deadhead the spent blossoms with the pruning shears by clipping the blossoms from the stems. Deadheading will promote continuous blooming. Remove dead and diseased stems from the hydrangea shrubs early in the spring by cutting them off at the base of the shrub.
Apply approximately 4 inches of shredded mulch around the base of the endless summer hydrangeas in late autumn to insulate the shrub from winter temperatures. Remove the mulch the following spring after the ground thaws.
