Is your soil on the heavy side? Your echinaceas would probably benefit from being lifted or protected over winter. Get them through the winter and they will prob do well for you in the summer
Hi Verdun, no, I've got a centuries old Roman Sand Quarry about 25 yards from the front of my House and I garden on around 350' or more of sand. I've improved the soil over the years with an initial 200 tons of top soil, followed by decades of adding farm manure, horse manure, home made compost [the heap is well over 8' and climbing], and hundreds of litres of commercial compost from containers and the like.
Armandii, gosh, you have worked hard. I'm on sandy loam so quite similar. Then, I think you can grow echinaceas but need to prevent flowering too early. Allow root system to build up first. Masses of compost too....am I envious or what?
Hi Verdun, I'm envious of other members gardens believe me!!! Some of the gardens displayed in the pics are tremendous and show a lot of devotion and passion. I'm afraid I just bumble along and keep packing plants in the borders and try to grow anything I see and like: I get plenty waste from the borders and the pond which all goes on the Compost Heap. I think I prefer gardening on sand as while it might be a hungry soil you can improve it more easily with manure, etc. As you can see I tend to plant everything on top of each other.
