Temperatures in our area during early spring are notoriously fickle. As a gardener, you should keep in mind that you are always taking a chance when you move plants outdoors in early spring. If you want to move plants outdoors safely, please pay attention to weather reports for frost and freeze warnings. Some plants are hardier than others, known as cold tolerance, but that isn't the only factor. Important conditions include where your home is located geographically and how well the new plants have been hardened off. As a concerned grower, Russell's follows these general guidelines for hardening off plants, that we grow in the greenhouse, from UMass Amherst.
When you have questions, don't hesitate to ask our knowledgeable staff for suggestions of the best cool tolerant plants for your landscape plus advice for providing protective coverage during cold snaps.
