Transplanting mature azalea
We got word of an old victorian house being torn down, and a number of very old azaleas in immanent danger of being destroyed, and we were offered as many as we could take. We transplanted two--about 5 feet tall (not including roots), and one of them was that height because it had been pruned in years past, from the look of the very thick limb that had been pruned. So we're talking MATURE. We dug a wide root ball, and put them in two even wider holes, with high quality compost. But the soil into which we put them was very clayish, and rocky (though we removed a bunch of rocks), compost aside. Been watering daily, will cut back to every other day after they've been in six weeks (been three weeks so far). Anything else we should be doing? Because of the last minute information on the tear-down, we didn't have time to prepare for this; but they look fabulous, like they've been there for years, and we want them to take, of course. So any further suggestions are welcome. I've read on other websites that there are liquid additions you can use in your watering to minimize shock, but none of the gardening centers near us have heard of this: anyone know anything about them? And is it too late to use such a product? PS, we live in a wooded area in SE PA, the azaleas get a few hours of sun each day, but not too much. We've been having drought, hence the vigorous watering.
