As autumn settles in, now is the perfect time to consider planting bulbs that will bring your garden to life next spring. While both spring and fall bulbs exist, understanding their differences is essential for successful gardening.
Timing is Everything
Fall bulbs, such as tulips, daffodils, crocus, and garlic, are typically planted around mid-October, when soil temperatures hover around 15°C (59°F) but before the ground freezes. In contrast, spring bulbs—like lilies, dahlias, and onions—are planted in May, usually around our last frost date. Always take note of your hardiness zone, as bulbs rated above a 4 may not return year after year.
Why Plant Fall Bulbs?
Planting fall bulbs comes with a host of benefits. For one, many fall varieties are among the earliest risers in spring, providing a vibrant splash of color well before most perennial plants start to awaken. Additionally, garlic planted in the fall tends to be ready for harvest sooner than spring-planted varieties. The best part? Once planted, these bulbs require minimal care, allowing you to enjoy your garden with less effort.
Choosing the Right Location
When selecting a spot for your bulbs, drainage is crucial. Bulbs are highly susceptible to rot if they sit in waterlogged soil for extended periods. Look for well-draining areas in your garden, and remember to consider spacing based on the specific requirements of each bulb type. As a general guideline, space tulips 4-6 inches apart, daffodils 3-6 inches apart, and garlic 3-6 inches in rows 12-14 inches apart.
The Planting Process
Once you've chosen your location and spaced out your bulbs, it’s time to dig. Follow the depth instructions on your bulb packaging. For tulips, plant 6-8 inches deep; for daffodils, plant at a depth 1.5-5 times the bulb’s length, remembering that larger bulbs need to be buried deeper. Garlic cloves should be planted 2-3 times their length.
As you dig, consider adding a tablespoon of low-nitrogen organic fertilizer, like bone meal, at the bottom of each hole. Choose a fertilizer with a low first number (nitrogen) and a higher second number (phosphorus) to promote root growth while minimizing leaf production.
After planting, cover the bulbs with soil and lightly compact it. Add at least 2 inches of mulch on top, and water them thoroughly—just once! This initial watering should saturate the soil, but be careful not to overwater as fall progresses into winter. To avoid disturbing the bulbs, it’s wise to mark their locations.
Spring Care and Maintenance
When spring arrives, try to resist the urge to water your bulbs, as excess moisture can lead to rot. After the blooms fade, trim the stalks back to the ground, but don’t be alarmed if the plant appears to die back completely. This is simply a natural dormancy phase. You can choose to leave the bulbs in the ground, which is the easiest option, or carefully dig them up for storage.
If you opt for storage, do so in late spring after the plants have died back. Carefully dig up the bulbs, clean off the dirt, and store them in a dry, cool, dark place in paper or mesh bags (egg cartons work well too). Check periodically for any signs of rot and discard any that show decay.
Special Considerations for Garlic
Garlic, unlike most other bulbs, needs to be harvested each year. After harvesting, select the largest and healthiest bulbs to use as seed garlic for the next planting. Cure them for at least two weeks before replanting in October.
Planting fall bulbs is an easy and rewarding way to inject early spring color into your garden while also getting a head start on your garlic harvest. So grab your gardening gloves and trowel—now is the best time to get those bulbs in the ground for a stunning spring display! Happy planting!
