The Q&A Archives: Why are my perennials dying??

Question: Every yoear we palnt my new pernnials and take very good care during the growing season. But in the spring our beds are gone. They look like we never planted any thing. Help!! (We live in VT And we do mulch)

Answer: I wonder if the drainage is poor during the winter months? If roots remain soggy they can die out over the winter months. The best way to avoid that is to incorporate some organic matter into the soil prior to planting this spring. Organic matter will loosen the soil, help it drain quickly and release nutrients as it decomposes - all the things your plants will love.
