spanish lavender dying one after another
I planted several of the spanish lavender plants in my front south facing (sandy soiled) bed and I have 3 out of 10 plants left. Itis in with Moss Rose and chrysanthimums and sedum. Everything has survived except the spanish lavenders. I thought lavender was a drought tolerant plant, but is this variety (lavendula stoechas) needing more water than most? It also didnt flower very good even when I added some fertilizer. What have I done wrong? I tried to water it as often as possible, but the soil must be the problem??????
