What Spring Bulbs Can You Plant Now?
If you're looking for spring bulbs to plant now, you're in luck. While many spring-flowering bulbs are best planted in autumn, there are still options that can be planted in late winter or very early spring for a later spring or even early summer bloom. The key is selecting varieties that tolerate cooler soil temperatures and have a shorter development cycle. Planting now ensures you can enjoy fresh growth and colour as the weather improves, potentially filling gaps or extending your garden's blooming season.
- Late winter/early spring planting is possible for some bulbs.
- Focus on varieties with shorter development times.
- These bulbs offer late spring to early summer colour.
- Consider filling gaps in existing displays.
The success of planting bulbs now hinges on choosing the right types and ensuring they have adequate time to establish roots before the peak growing season. Some bulbs might have been stored and are available for late planting, offering a chance to add more colour to your garden even if you missed the autumn window. These late-planted bulbs might take slightly longer to emerge but will reward your efforts with beautiful blooms.
This approach is particularly useful if you're looking to fill unexpected gaps in borders or containers, or if you've decided to add more colour to your garden later in the season. By selecting appropriately, you can still achieve a wonderful display.
Choosing the Right Bulbs for Late Planting
Not all spring bulbs are forgiving of late planting. Those with a longer dormancy period or requiring extended chilling are less likely to perform well. Instead, focus on bulbs known for their resilience and ability to grow quickly once soil temperatures rise. Many types of Liatris, Gladiolus (if planting for summer colour), and some Alliums are good candidates for planting in early spring. If your aim is strictly spring bloom, look for those that are often sold specifically as 'pre-chilled' or 'forced' bulbs, as these have had their chilling requirements met and can often be planted a little later.
It's crucial to check the specific planting recommendations for any bulb variety you consider. Some suppliers may offer bulbs that have been specifically prepared for late-season planting, making them ideal for your current gardening needs. These can often be found under categories like 'spring planting' or 'summer flowering' bulbs.
What to Plant in March for Spring and Summer Colour
March is a pivotal month for gardeners, marking a transition from winter to spring. For those keen on planting spring bulbs now, March offers a good opportunity, especially in milder climates. While the earliest spring flowers like crocuses and snowdrops are usually planted in autumn, bulbs planted in March can still yield impressive results, often providing late spring or early summer displays.
Late Spring Bloomers
Many types of Allium (ornamental onions) are excellent choices for planting in March. Varieties such as Allium 'Purple Sensation' or Allium hollandicum 'Persian Pearls' will bloom in late spring to early summer, offering striking architectural flowers. They are robust and generally perform well even with a later start.
Another reliable option is the Agapanthus. While often planted in late spring or early summer for summer blooms, planting them in March can give them a head start in establishing their root systems. They will produce beautiful globe-shaped flowers in shades of blue and white.
Summer Flowering Bulbs for Early Planting
If your interest lies in summer colour, then March is an ideal time to plant many summer-flowering bulbs. Dahlias, for instance, can be planted now, either directly into well-prepared beds or started off indoors in pots. They require protection from frost if planted outdoors early. Begonias and Cannas are also great options, offering vibrant foliage and flowers throughout the summer months.
Consider planting Gladioli corms in succession from March through to May for a continuous display of their elegant spikes throughout summer. For a more exotic feel, plant Tigridia (Mexican Shell Flower) now; their intricate blooms are a delightful surprise.
The success of planting bulbs in March lies in selecting varieties that benefit from a cooler start and can grow rapidly once warmer weather arrives.
When planting now, ensure the soil is workable – not waterlogged or frozen. Good drainage is paramount to prevent bulbs from rotting. Amending the soil with compost or grit can improve structure and drainage, giving your bulbs the best possible start.
Alternative Planting Strategies and Considerations
Beyond selecting the right varieties, timing and location are crucial when planting spring bulbs now. Understanding the soil temperature and moisture levels will directly impact your success. If the ground is still quite cold and wet, it might be prudent to delay planting slightly or opt for container planting where soil conditions can be controlled more effectively.
Container Planting for Control
Containers offer a significant advantage when planting bulbs late. You can fill them with a high-quality potting mix that provides excellent drainage and aeration, irrespective of your garden soil's condition. This is especially useful for bulbs that are more sensitive to waterlogging. Many spring bulbs, from tulips and daffodils to hyacinths and crocuses, can be planted in pots for a concentrated display on patios or balconies.
Planting in containers also allows you to move them to a sheltered spot if unexpected frosts occur, protecting vulnerable new growth. For bulbs like Alliums or even dahlias, starting them in pots indoors or in a sheltered cold frame can give them a crucial head start.
Soil Preparation is Key
Regardless of whether you're planting in the ground or in containers, good soil preparation is non-negotiable. For beds, dig in plenty of organic matter like compost or well-rotted manure to improve fertility and drainage. If you have heavy clay soil, adding grit or perlite will help prevent the bulbs from sitting in water. For bulbs planted now, a balanced, slow-release fertiliser can provide essential nutrients for strong root and stem development.
Ensure bulbs are planted at the correct depth; generally, this is about two to three times the bulb's height, but always check the specific variety's needs. Planting too shallow can expose them to frost damage, while planting too deep can delay or prevent emergence.
Extending the Bloom Season
By carefully selecting a range of bulbs that have different flowering times, you can create a succession of colour from early spring right through to early summer. This involves planning which bulbs to plant now, alongside those already in the ground from previous seasons. Consider grouping bulbs that require similar conditions and planting depths. This strategic approach ensures your garden remains vibrant and attractive for an extended period, making the most of every planting opportunity.
