There are various Hippeastrums growing in my garden, sending up scapes. I used to grow them along the concrete path by the front gate where they were thriving, but in the narrow strip along the path, they tended to hang over the path and make it difficult to get past. So planted them elsewhere with good drainage but after 2 years realised I was going to lose the lot if I didn't do something about it. As they had been happy by the concrete path, had to relocate to another concrete path, by the clothesline. So now they are thriving again. It will be interesting to see which ones have survived, 9 scapes so far, and I hope that not just one or two will be repeated over and over. What I am wondering, why are they happy by a concrete path? I also have a few further up the slightly sloping area where they are now, but have put brick strips by them hoping that may do the same as the concrete path, and it seems to be working. But why?
