UMass Extension's Garden Calendar

The intense petal color of some tulip varieties helped to spark the historical European interest in tulips. A renewal of a long-standing annual tradition… a useful, stimulating, and educational monthly wall calendar from UMass Extension.

Our Extension Specialists have compiled the latest collection of uplifting images of garden and landscape plants well-suited for the Northeast. Each date features a timely, research-based tip such as when to fertilize, insect and disease alerts, or when to be especially tick-aware.

Purchasing plants for the landscape can be a considerable investment in both time and money. Selecting the right plant for the right place is the first step in making the most of this investment. This means selecting the best-suited plant material for your location according to light exposure, water availability, hardiness zone, soil conditions, and environmental exposure. The next step, and just as important to success, is following proper planting procedure.

Our 2024 calendar includes guidelines for preparing the planting hole, avoiding problems with circling roots, amending the soil before planting, and shares the results of a two-year UMass study looking at plant establishment success using different root preparation methods at planting.
