The soil in one of my flowerbeds that gets the morning and early afternoon sun needs enriching. It is very dry. Seems like roses is the only thing that grows there. How do I make that soil richer in the Fall. I have planted some of my WS plants there but they don't seem to be showing much growth. Last Fall, I was given a garden phlox and a black eye susan. Those have great growth so I am hoping they will bloom this summer. The 3 rose bushes that are planted there do beautifully. With the exception of the minature rosebush that I planted, the other two rose bushes were there when we moved here so I have no idea what variety they are, except what color blooms they produce. An ice plant that my daughter bought back from the beach has managed to grow there but hey, they should grow anywhere, right? I am surprized that the roses grow there. Most of that flowerbed is under the eaves of the house, so it doesn't get a lot of rainfall. I just transplanted a monarda that somebody gave me there, so I am hoping it takes off. Somebody else sent me some liatris and they have taken off and are showing potential. Would love to get more low maintence perennials started there. Any suggestions about enriching that soil? What do I add? top soil or garden soil or soil with composted manure?
