How fast hydrangeas grow
Hydrangeas respond well to several propagation techniques, including layering and dividing. But Dirr's method for rooting softwood cuttings in summer will yield a bunch of new plants in about four weeks. To do it, locate a stem of softwood between the hard, woody growth at the bottom of the plant and the fleshy green tip by bending it; softwood should snap cleanly. Cut a softwood shoot that has several leaves. Trim it into 5-inch-long pieces that each have a leaf toward the top.
Remove extra leaves; Dirr goes a step further and cuts the remaining leaf in half to minimize evaporation and the need for watering. Dip the other end in powdered rooting hormone; plant the cuttings in trays filled with a soilless mix and perlite.
Cover with a plastic bag, and stash in a shady location, misting regularly to keep the leaf hydrated. After four weeks, tug on it to check for roots; once roots are developed, transplant to a bigger pot and feed with a slow-release fertilizer.
By next spring, cuttings will be ready to go in the ground.

You can prune these hydrangeas to shape them into trees with single or multiple trunks. Urban growing conditions suppress the growth rate of many plants. Hydrangea paniculata cultivars are not among them. They will grow rapidly in partial shade to full sun and will tolerate air pollution. These hydrangeas like organically rich soil with medium moisture that drains well.
If you want a hydrangea tree to grow rapidly and flourish, do not plant it where it will be growing in the shade all day. A hydrangea in the shade may not blossom or may look scraggly. Flush the soil with water to remove the salts and other problems. Then, let the top of the soil dry for a day or two before watering again, and abstain from fertilizing until the plant is healthy once again. Yes and no. Oftentimes potted hydrangeas are given as springtime gifts that can be kept indoors, but it can be tricky to help them respond well to live past a season.

It may be best to plant your potted hydrangea outdoors in your garden for best results. You can change the color of your hydrangea flowers by tinkering with the soil. Change blue flowers to pink flowers by decreasing the acidity of your soil. Do this by adding hydrated lime to the soil in the spring.

These terms can be confusing, which often leads to pruning off the wood that could hold next season's blooms. Make a note of the type of hydrangea you have, when it blooms, and the best pruning practices for the plant. If your hydrangea flowers in the early summer, you have a plant that blooms on old wood previous year's stems. If your hydrangea flowers mid- to late summer, you have a plant that blooms on new wood the current year's stems.
Yes, you can train a hydrangea shrub into a small flowering tree with a single trunk, but be patient because the process can take a few seasons to complete.
