Pink or Blue????? There isn’t one universal answer for planting time and it really depends on the weather. It’s best to wait until the last chance of frost or severe heat has passed so the plants have the best possible chance of survival. If it’s over 85 degrees consistently, it’s probably too warm. If temperatures are less than 40 degrees, it’s probably too cold. A late frost can nip the buds and reduce the number of blooms. If your hydrangea macrophyllas are blue and you want them to be pink or red, add Hydrated Lime. But if you want your pinks to be blue or purple, add Aluminum Sulphate. Blossom colors of some varieties, such as arborescens (Annabelles), or serratas, aren’t very pH sensitive and won’t change colors. Serratas tend to give a mixture of colors that change as they age. Good soil is important for root growth and supplying water to the hydrangea’s leaf and stem structure, but most importantly the flowers. And here are some great components that can be added to improve your soil: grass clippings, clean and disease free leaves, homemade compost, well-aged manure, mushroom compost, store bought potting mix, perlite, or peat moss. Mix these into the soil in early spring a few weeks before you begin planting. When to Prune. . . The timing and method depends on the species and the age of the hydrangea. Pruning is always a matter of debate but in the case of the Hydrangea macrophyllas too little is preferable to too much. Do not prune by shortening stems, except to remove just the old flowerheads, as you are likely to cut off your flower buds. Actually, it’s best to leave the dried heads of old blooms on the plant until winter’s end to help protect new flower buds. When danger of late frost is past, carefully deadhead old blooms by cutting off above the first pair of vigorous new buds. If needed, a young plant may be cut back in June/July to enhance it’s structure or fullness and this should not harm next year’s bloom. Likewise, if you need to rejuvenate an overgrown, tired, or non-blooming older macrophylla, you should do this corrective pruning, shaping and thinning in the middle of mid-summer for the same reason: your shrub will have the maximum time to produce new branches and harden off before the first fall freezes. A few of the macrophyllas are remontant, re-blooming, with flowers forming on old growth and new growth. This means that even if all preformed flower buds are killed by cold, new flowers will develop on the current season’s growth. As for Hydrangea arborescens and Hydrangea paniculata, you can prune them in late winter as they bloom on new growth and will respond to this pruning by sending out new growth and flowers. Hydrangea quercifolia is much like Hydrangea macrophylla in that it blooms on the previous year's growth and so should not be pruned at the end of winter as flowers will be lost. Renewal pruning (removing 1/4th of the old wood at the base) is suggested on an annual basis. Mid-South Hydrangea Society 635 West Dr. Memphis, TN 38112 (901)452-4667 E-Mail: [email protected]
