Bulb Planting
Fall is a great time to plant bulbs for spring beauty. In this webinar, you’ll learn essential tips on how to select the perfect bulbs, correctly plant them, and protect new plantings.
Extend the Season
Cold frames and hot beds, hoop houses, cloches, and floating row covers allow gardeners to grow plants earlier in spring and later in fall. Although these structures are used primarily for growing vegetables, they may be used for growing ornamentals, including flowering plants, as well.
