Fall is the Time to Plant Spring-Flowering Bulbs
Posted on September 13, 2019
Spring-flowering bulbs, like tulips, daffodils, hyacinths, and crocus, are the first group of plants to bloom in the spring. The vibrant colors and new green growth announce to us spring is on the way. However, even though we enjoy these beautiful flowers in spring, fall is the season to plant these bulbs.
When buying your bulbs, keep the following in mind:
Choose a sunny site for your spring-flowering bulbs. Most bulbs need at least six hours of full or partial sun each day and do best when planted in an area that has good drainage. If the soil contains considerable clay, mix in some organic matter such as compost, peat moss, or rotted manure. At planting time, you may also want to mix into the soil a slow-release bulb fertilizer,
Plant spring-flowering bulbs from mid-September until the soil freezes (usually in November). For best results, plant bulbs by mid-October. This will give them a chance to establish a healthy root system before the ground freezes and will assure a quick start in the spring. But … if time gets away from you and it is late fall, plant your bulbs anyway. Many a bulb has bloomed in the spring after being planted late in the season.
Plant bulbs at a depth equal to two to three times their diameter. Plant bulbs a little shallower in heavy (clay) soils. When planting, be sure to identify either the root plate and face it downwards or find last year’s shriveled flower stalk and face it upwards. If unsure, compare with pictures/diagrams often found on the bulb package wrapper or in gardening books/magazines.
After planting, bulbs will start to form roots immediately and need water for this process. Soak the bulbs thoroughly so that the soil around the bulbs is moist. One good soaking is usually enough unless we experience an unusual hot and dry fall.
Although spring-flowering bulbs are hardy, they need winter protection. Once the ground freezes in late fall, place two to four inches of mulch over the soil. This will keep the soil frozen once it freezes and help prevent freeze/thaw damage. Remove the mulch in spring after the first leaves appear. The new leaves may rot if you allow them to remain in contact with the mulch.
