While my grandparents are out of town, I am going to add a layer of compost to her flower beds and look into whiteflies(she has had a problem with them for a few years). They take excellent care of thier yard, but have never used compost!, she just put down some mulch for the first time(redwood). I am going to put the compost under this.
Anyhow, any other suggestions for quick and easy things I could do??
