As September ends, and October begins most of the country if you live in the U.S. is in prime bulb planting season! However, for us down South - thats a pretty warm time of year still. September is Augusts cousin, and the majority of October is still warm enough to be in shorts and a T-shirt. We then get a breeze move through around Halloween for a few days, then right back to warm and humid yet again until maybe around Thanksgiving. Then there is false winter that moves in around December.
Most of the time its not until mid-January that the deep south gets any consistent cold weather, which is promptly shooed-off come the end of February, and thus the cycle begins again!
So, if you're wondering when on EARTH you are supposed to stick those bulbs in the ground... winter (or at least what we call winter) is the time to act.
For USDA hardiness zones 8+ Mid-December through Mid-January is prime time to plant bulbs, when the majority of the country is under snow and ice.
Why Plant Bulbs in Winter?
1. Embracing the Mild Southern Winter:
One of the primary advantages of winter bulb planting in the Deep South is the mild climate. Unlike their northern counterparts, Southern winters are relatively gentle, allowing for extended periods of ground activity. This creates an ideal environment for bulbs to establish robust root systems before the arrival of spring.
2. Early Spring Revelry:
Planting bulbs in winter means you're setting the stage for a grand spring performance. By providing bulbs with a head start, you're ensuring an early burst of color and fragrance that will put your garden in the spotlight long before the rest of the country.
3. Frost-Proof Beginnings:
Winter bulb planting reduces the risk of frost damage that can plague spring-planted bulbs. Often times if bulbs are planted too early in the South they can awaken prematurely and end up getting damaged. With this approach, bulbs acclimate to the soil and settle in, minimizing the vulnerability that comes with the transitional period between winter and spring.
4. Opportune Soil Preparation:
Winter's cool embrace is the perfect time to prepare your soil in the Deep South. With more manageable temperatures, gardeners can focus on creating the optimal conditions for their bulbs, ensuring a robust and thriving garden come spring. Adding compost where needed, and a great quality starter fertilizer like Espoma's Bio-Tone Starter Plus and Bone Meal Fertilizer can really set the stage for success by spring. Use a bulb auger like the THIS ONE, and you're good to go!
Here are 5 Great Bulb Suggestions for the Deep South!
1. Amaryllis (Hippeastrum):
Yes indeed! Those holiday beauties can grow in USDA zones 8+ in most cases. Red Lion is a tried and true variety that returns and blooms reliably even after 10F!
Planting Time: Very Late Fall to Early Winter
Bloom Time: April - May typically
Amaryllis bulbs are the showstoppers of Southern gardens. Don't let these Christmas time flowers fool you; they are a spring surprise when planted in the landscape. With their large, trumpet-shaped flowers in an array of colors, they bring elegance and drama to any planting bed. Plant amaryllis bulbs in well-draining soil, burying them with about one-third of the bulb above the soil surface. You want just the neck of the bulbs where the leaves emerge to be above ground level. Ensure they receive ample sunlight (5+hrs direct sun) for optimal blooming. Many times, if you purchase these blooming bulbs during the holidays, they can be planted in the garden and once established will bloom in the spring the following year forward.
2. Crinum Lily (Crinum spp.):
Planting Time: Fall to Early Winter
Bloom Time: Late Spring/Early Summer - nearly year-round in warmest climates
Crinum lilies are well-suited to the Southern climate, offering large, fragrant blooms in various shades. Plant bulbs in a sunny or partially shaded location with rich, well-draining soil. Crinums prefer slightly acidic to neutral soil pH. Space bulbs about 12 to 18 inches apart, burying them at a depth of 4 to 6 inches.
3. Rain Lily (Zephyranthes spp.):
Planting Time: Late Fall to Early Winter
Bloom Time: Spring - Fall depending on the variety
Rain lilies are petite, resilient bulbs that produce charming, trumpet-shaped flowers. These bulbs are adaptable and thrive in well-draining soil. Plant them in clusters for a more impactful display. Rain lilies prefer full sun to partial shade and will reward you with blooms after a good rainfall.
4. Narcissus (Narcissus spp.):
Planting Time: Late Fall to Early Winter
Bloom Time: Late Winter - Mid-Spring variety dependent
Narcissus, commonly known as daffodils, are reliable and low-maintenance bulbs for Southern gardens. Great varieties for the South are Erlicheer, Ice Follies, Mount Hood, and Pink Charm. Plant them in well-draining soil, about 4 to 5 inches deep and 4 to 6 inches apart. Choose a location with full sun to partial shade. Daffodils naturalize well, meaning they multiply and come back year after year.
5. Gladiolus (Gladiolus spp.):
With their iris like leaves, and towering blooms gladiolus make great additions to a cottage theme garden in USDA zones 7b-10. (some varieties are as cold hardy as zone 5!)
Planting Time: Late Fall to Early Winter
Bloom Time: Late Spring - Summer
Gladiolus bulbs add vertical interest with their tall spikes of colorful flowers. Plant them in well-draining soil, about 6 inches deep and 6 inches apart. Provide support with flower stakes for the tall flower spikes to prevent them from bending or breaking. Gladioli prefer full sun and can be staggered in planting for a prolonged bloom period.
Tips for Successful Winter Bulb Planting:
1. Site Selection:
Choose a well-draining location for your bulbs to prevent waterlogged soil, which can lead to bulb rot. Most bulbs prefer full sun, so select a spot that receives at least 6 hours of direct sunlight each day.
2. Soil Preparation:
Enrich your soil with organic matter, such as compost, to improve fertility and drainage. Well-amended soil provides a welcoming environment for bulbs to establish healthy root systems. To learn more about organic matter check out our blog article: What is organic matter anyway?
3. Planting Depth:
Follow the recommended planting depth for each type of bulb. As a general rule, plant bulbs two to three times their diameter deep. This ensures they have enough soil cover for protection and stability. With heavy flowering daffodils and gladiolus stability is a must!
4. Watering:
While bulbs need moisture for growth, it's crucial to avoid waterlogged conditions. Water the bulbs after planting and keep the soil consistently moist but not soggy. Mulching can help retain soil moisture. Once planted bulbs in the soil typically don't require addtional moisture during the cool season. If the soil is dry when planting, give them a good deep drink to settle them in. Unless rainfall is scarce watering too much in winter will lead to rot.
5. Fertilization:
Apply a balanced, slow-release fertilizer at planting time, like the one's mentioned above and below, to provide essential nutrients. Avoid excessive use of high-nitrogen fertilizers, as this can encourage foliage growth at the expense of flower development.
Conclusion:
Winter bulb planting in the Deep South is a strategic and rewarding endeavor for gardeners eager to embrace the beauty of spring a little earlier. By selecting the right bulbs and adhering to essential planting tips, you can cultivate a garden that bursts forth with color, fragrance, and vitality. So, roll up your sleeves, grab your gardening gloves, and let the Southern winter be the canvas for your botanical masterpiece. Happy planting!
