Horticulture Questions Hot Line
The Horticulture hotline (HortLine) of the Penn State Extension Philadelphia Master Gardeners is a free service for residents of Philadelphia. Master Gardeners are ready to answer questions pertaining to the appropriate selection of vegetables, ornamental plants, pesticides, soil, plant identification, pruning, compost, mulch, insect control, plant diseases and more.
The HortLine can also answer questions about canning garden produce and food safety. If we cannot answer the question ourselves we will refer it to the Penn State University Hotline.
