I realy need your help. I have a raised flower bed in the front of my house and cannot keep flowers alive. There is a rose bush, columbine, cora bells, blackeye suesans, hostas, dasies and a lilly. all not doing so well (turning yellow, wilting and/or just stoped blooming). They get plenty of sun light and water, soil has been turned and fertilized (Scotts rose and bloming flower pellates) and i use peet moss instead of mulch. I do the same for the back yard and my plants are doing great! what am i doing wrong?
