I live in Victoria, on Vancouver Island, so typical northwest mild climate, wet winters and warm, dry summers. We just moved into a house this April which has a large L-shaped wildflower garden in the back yard.
The wildflowers have bloomed from March-October, at least 30 species, very nice. However, since early October they have died off, leaving stalks (which we pulled after shaking off seeds), but now there is a mat of weeds and fine grass growing throughout the bed, through which I do not think some wildflowers will be able to get through in the spring.
I have consequently taken a hoe and scraped and raked the upper 1-2" of soil, thereby loosening it and removing all the weed and grass, ensuring I have taken as little soil and seeds out as possible.
I am unsure whether that was the right thing to do for this annuals wildflower garden? Any other ideas appreciated.
Also, would a thin layer of leaf mulch be ok for this bed and what sort of fertilizer shall I apply in the spring?
thanks....Larry Gagnon
