The usual term is cuttings rather than rootings, you should find much more searching with the customary word. With cuttings of deciduous trees and shrubs it is often necessary to follow a comparatively strict procedure in order to get them to both form roots and then grow away again the following spring. If the tips of the rooted cuttings do not have time to flush a new stem growth, form overwintering terminal bud the cuttings may fail to continue growing the following spring - despite having had roots and remained alive up to that point. To overcome this more difficult kinds are taken as early as possible in the growing season, put under mist to keep them from shriveling before the roots form. But if you are getting some new top growth from at least the one cutting this may not be your problem - at least with the one cutting. If it did not form very many roots there may not be enough of a root system yet to support a full top growth. Or there could be some other problem or limitation present, it sounds like it may have died back a bit.

Yes: amending of individual planting holes with organic material when setting out long-term plants like trees and shrubs is counterproductive, due to how it affects movement of water into and out of the amended planting hole.

Somebody from another forum told me the term was rootings. Okay I will use the term cuttings for my research then.

I have two photos, but I am not sure how to attach photos to this forum. How do I attach the photos so that I can show you what these cuttings look like?

Thanks!
