What Veggies to Plant in March for Early Spring Success
March is a key month for gardeners looking to get a head start on the growing season. While the weather can still be unpredictable, it’s an ideal time to sow seeds for many hardy vegetables that can tolerate cooler soil temperatures and potential frosts. Success with veggies to plant in March often hinges on choosing the right varieties and understanding your local climate’s specific conditions.
- Direct sow hardy greens and root vegetables.
- Start tender crops indoors for later transplanting.
- Prepare soil beds for optimal growth.
- Select varieties suited for cooler spring conditions.
The focus for March planting is typically on crops that benefit from a long, cool growing period or those that can be protected from harsher late-winter conditions. Many gardeners begin with direct sowing, placing seeds straight into the ground where they will grow. Others opt to start seeds indoors, nurturing them into sturdy seedlings before transplanting them outside once the risk of severe frost has passed.
Hardy Greens for Direct Sowing
Leafy greens are often the stars of early spring gardens. Spinach, for instance, thrives in cool weather and can be sown directly into the soil as soon as it’s workable. Its quick growth cycle means you could be harvesting fresh leaves within weeks. Similarly, lettuce varieties, particularly loose-leaf and romaine types, are excellent choices. They grow rapidly and can be succession-sown every few weeks to ensure a continuous supply throughout spring. Other robust greens like Swiss chard, kale, and rocket (arugula) are also well-suited for March planting. These varieties are generally cold-tolerant, meaning they can endure light frosts, making them reliable options for sowing outdoors this month.
Root Vegetables to Consider
The cool, moist soil of early spring is perfect for many root vegetables. Carrots, particularly shorter or round varieties, can be sown directly into well-dug, stony-free soil. Radishes are renowned for their speed; many types mature in under a month, making them a satisfying crop for impatient gardeners. Beetroots can also be sown now, offering both delicious roots and edible greens. For those with slightly deeper soil, parsnips and turnips are good candidates for a March sowing, though they will require a longer growing season to reach maturity. Peas, while technically legumes, are often treated like root vegetables in terms of planting time and preference for cool soil; they can be sown directly as soon as the ground is workable.
Starting Tender Crops Indoors
While many veggies to plant in March focus on cold tolerance, this month is also crucial for initiating the growth of tender crops that cannot withstand frost. Tomatoes, peppers, aubergines (eggplants), and cucumbers are prime examples. These require warmth to germinate and establish strong seedlings. Sowing them indoors in pots or trays, in a warm, bright location, allows them to develop sufficiently before the last frost date. It’s vital to use a good quality seed compost and ensure consistent moisture and warmth. These young plants will be transplanted outdoors into their final positions later in spring, usually after all danger of frost has passed.
Preparing Your Garden Beds
Regardless of what you choose to plant, preparing the soil is paramount. As soon as the ground is dry enough to work – meaning it doesn’t clump excessively when squeezed – turn it over. Incorporate well-rotted compost or manure to enrich the soil and improve drainage. This is especially important for root vegetables, which need loose soil to develop unimpeded. For direct sowing, aim for a fine tilth on the soil surface. If you are planting out seedlings started indoors, ensure the planting holes are dug to accommodate their root balls, and consider adding a little fertiliser to give them a good start. Good soil preparation is fundamental to successful gardening, especially when starting crops early in the season.
The rhythm of the seasons dictates what thrives; March planting is about embracing resilience and foresight.
Protect young seedlings from late frosts by covering them with fleece or cloches, especially if you've transplanted tender crops or sown very early in the month.
When selecting veggies to plant in March, consider the specific needs of each crop and the conditions in your garden. Some plants, like onions and leeks, can also be started from seed indoors or planted out as 'sets' (small bulbs) or seedlings at this time, depending on your preferred method and local climate.
Which Spring Bulbs to Plant Now for Colour
What spring bulbs can you plant now for a vibrant display?
While the focus for many is on vegetables, March is also a crucial time for planting certain types of spring bulbs that will bloom later in the season or have specific planting requirements. Unlike autumn-planted bulbs that bloom in early spring, many summer-flowering bulbs are best planted as the soil begins to warm up. However, some hardy options that overwintered can still be planted now if missed in the autumn or if you're looking to fill gaps. For many, the real planting season for summer-flowering bulbs like dahlias, gladioli, and lilies begins in earnest in April, but March is the time to prepare and get organised.
Hardy Bulbs and Perennials
If you've acquired any hardy summer-flowering bulbs that might have been in storage, or if you are looking to plant perennials that flower in summer, March is a suitable time. For example, certain types of lilies can be planted now, provided the ground is not frozen. Similarly, if you missed planting certain types of spring bulbs in autumn that are known to be quite hardy and can survive a bit of frost, March might be your last chance to get them in the ground, though success is less guaranteed than with autumn planting. These might include robust daffodils or tulips that can still establish roots. It’s always best to check the specific planting instructions for each variety, as some are more forgiving than others.
Preparing for Summer Blooms
The most common activity related to bulbs in March is preparation for summer-flowering types. Many gardeners will be bringing stored tubers and bulbs indoors to inspect them and perhaps start them off in pots in a greenhouse or on a sunny windowsill. This includes popular choices such as dahlias, which benefit from a head start to ensure a good flowering period. Gladioli corms can also be planted in succession from March through to May to achieve a staggered display of blooms. It’s about getting your orders in, clearing space, and planning where these colourful additions will go in your garden. Understanding when to plant spring bulbs or summer blooms is key to a continuous garden display.
Considering Container Planting
For those with limited garden space, or for adding flexibility to your displays, planting bulbs in containers is an excellent option. Many spring bulbs, and indeed some summer-flowering types, do well in pots. Ensure you use a good quality potting mix and a pot with adequate drainage holes. Early-flowering bulbs that might have been missed in autumn planting can still be put into pots now and placed in a sheltered spot. For larger pots, consider layering different bulbs to create a multi-tiered display as the season progresses. This approach, often referred to as 'lasagne gardening' with bulbs, can provide interest for months. Winter plants for pots often transition into early spring performers, making containers a dynamic part of the garden.
When to Plant Spring Bulbs vs. Summer Bulbs
The critical distinction lies in their flowering time and hardiness. Spring bulbs (like tulips, daffodils, hyacinths) are typically planted in autumn to allow them to establish roots over winter and bloom in early to mid-spring. Summer bulbs (like gladioli, dahlias, lilies) are planted in spring, once the soil has warmed sufficiently and the risk of frost has diminished, so they can grow and flower during the warmer months. While you can plant some hardy spring bulbs in March, it's a gamble. The primary focus for bulbs to plant now, if not for vegetables, is preparing for summer blooms or planting any remaining hardy varieties before it’s too late.
Don't underestimate the resilience of nature; even in March, there's potential for growth and beauty. The right soil preparation is key for both vegetables and bulbs.
Use mulch generously around newly planted bulbs and seedlings to retain moisture and suppress weeds, a vital step in the unpredictable March weather.
Alternatives and What to Plant Now
What vegetables can I plant now besides the main crops?
While familiar choices dominate the March planting calendar, exploring alternative options can lead to a more diverse and interesting garden. This month isn't just about the standard brassicas or root vegetables; it's an opportunity to experiment with less common crops or to focus on specific planting methods that suit your garden's microclimate.
Exploring Unusual Greens
Beyond spinach and kale, consider sowing less common, yet equally hardy, greens. Mache (corn salad) is incredibly cold-tolerant and has a delicate, nutty flavour. Miner's lettuce is another hardy option that self-seeds readily once established. Oriental greens like tatsoi and mizuna also grow well in cooler temperatures and offer a peppery kick. These offer a point of difference and can be sown directly into the ground now, provided the soil is workable. They often require less space and mature relatively quickly, making them excellent additions for a varied harvest.
Onions, Leeks, and Garlic
March is often the last call for planting certain alliums. Garlic planted in autumn usually overwinters, but spring-planted garlic can still be successful if planted early in March, although bulbs may be smaller. Onion sets (small bulbs) can be planted out now, as can leek seedlings. If you're starting onions from seed, it’s typically done indoors earlier in the year, with transplanting happening in March or April. These crops are fundamental to many cuisines and, like root vegetables, benefit from well-prepared, free-draining soil.
Brassica Alternatives
While broccoli and cabbage might be started earlier or planted later, some hardier brassica relatives can be sown in March. Kohlrabi, for example, is relatively quick-growing and tolerates cool weather. Brussels sprouts can be sown in modules indoors or direct-sown in milder areas. Mustard greens offer a quick, spicy addition to salads and stir-fries and can be sown directly. These alternatives provide variety within the brassica family, often with slightly different growing habits or flavour profiles.
Using Polytunnels or Cold Frames
For gardeners seeking to extend the planting window or grow more tender crops earlier, polytunnels or cold frames are invaluable. These structures offer protection from wind and frost, raising the soil temperature and creating a more stable environment. Within these protected spaces, you can sow seeds of crops that would normally be planted much later, such as tender beans or even heat-loving herbs. March is an excellent time to set up these structures and begin sowing in them, allowing you to get a significant head start on the growing season for a wider range of plants than would otherwise be possible.
Considering Your Climate and Soil
Ultimately, what to plant now depends heavily on your specific location and soil conditions. A gardener in the south of England will have different opportunities in March than someone in Scotland. Always consider your average last frost date and the soil temperature. If the soil is still waterlogged and cold, it's best to wait a little longer for direct sowing. Conversely, if you have a mild climate and well-draining soil, you might be able to push the boundaries and sow slightly earlier or plant varieties that are borderline hardy. Even plants to plant in winter uk might have a later planting window extend into early March in warmer regions.
The versatility of March planting means you can tailor your choices to your preferences and resources. Success often comes from observing your garden's microclimate.
Sow seeds in modules rather than direct sowing for smaller seeds or in areas prone to slug damage; this provides better control and protection for young sprouts.
Key Considerations for March Vegetable Planting
What are the most important things to remember when planting veggies in March?
Successfully planting veggies in March requires a blend of preparedness, observation, and a willingness to adapt to the season’s vagaries. It’s a month that bridges winter and spring, demanding careful consideration of soil conditions, expected weather, and the specific needs of the crops you intend to grow. Understanding these factors will significantly increase your chances of a thriving garden.
Soil Temperature and Workability
The single most critical factor for successful March planting is soil condition. Seeds need a certain soil temperature to germinate, and trying to sow too early when the ground is cold and wet can lead to poor germination rates, rotting seeds, or fungal diseases. Perform the 'squeeze test': take a handful of soil and squeeze it. If it forms a tight ball that doesn't crumble, it's too wet. If it crumbles easily, it's ready. Aim for a fine tilth on the surface for direct sowing, which means breaking up larger clods of soil. For root crops, deeper cultivation to remove stones and improve drainage is also essential.
Hardiness and Frost Tolerance
When choosing veggies to plant in March, prioritise those known for their hardiness and tolerance to cool temperatures and potential light frosts. Crops like spinach, lettuce, peas, radishes, and certain brassicas (like kale and collard greens) are excellent candidates for direct sowing. If you plan to transplant seedlings started indoors (e.g., tomatoes, peppers), ensure you harden them off gradually for about a week or two before planting them out. This acclimatises them to outdoor conditions, reducing transplant shock. Always be prepared to protect very young plants with fleece or cloches if a sudden cold snap or frost is forecast.
Succession Planting for Continuous Harvest
March is an ideal time to think about succession planting. This involves sowing small batches of fast-maturing crops, such as radishes and lettuce, at intervals of a few weeks. By doing this, you ensure a continuous supply of fresh produce rather than a single glut. For example, sow half your lettuce seeds now and the rest in three weeks. This method is particularly useful for greens and root vegetables. Planning for succession maximises your garden’s yield over the spring and summer months, making the most of the available growing space and season.
Pest and Disease Management
As the weather warms, pests and diseases begin to emerge. Slugs and snails are notorious for attacking tender young seedlings, especially brassicas and hostas. Early detection and preventative measures are crucial. Consider using barriers, organic slug pellets (used sparingly and responsibly), or encouraging natural predators. Clubroot can be an issue for brassicas, so crop rotation is important. Ensuring good air circulation and avoiding overcrowding also helps prevent fungal diseases. Vigilance is key from the moment seeds are sown.
Choosing the Right Varieties
Not all varieties of a particular vegetable are created equal, especially when it comes to early spring planting. Look for cultivars specifically bred for cool-season growing or early harvests. For carrots, choose shorter or round types that mature faster. For peas, opt for early-maturing varieties. When sowing greens, some are naturally more bolt-resistant, meaning they are less likely to go to seed quickly in warmer weather. Reading seed packets carefully and choosing varieties suited to your climate and desired harvest time will pay dividends.
Embrace the potential of March; it's a month of planting and promise. Understanding your soil is the foundation of a successful vegetable garden.
Companion planting can help deter pests; for instance, planting radishes near cucumbers can deter cucumber beetles, and marigolds are known to deter nematodes and other soil-borne pests.
