Answering 'What Seeds to Plant Now?'
The answer to 'what seeds to plant now' is intrinsically linked to your specific geographical location and the prevailing season. There isn't a single universal answer, as conditions vary dramatically. This guide helps you navigate the optimal times to sow seeds for both flowers and vegetables, ensuring successful germination and growth, whether you're in the UK or elsewhere.
- Timing is geographical and seasonal.
- Consider both flowers and vegetables.
- Prepare soil for best results.
- Check local frost dates.
Understanding your local climate is the first step. Factors like average last frost dates in spring, first frost dates in autumn, and winter minimum temperatures dictate precisely which seeds will thrive when sown. For example, while some hardy vegetables can tolerate cool soils and even light frosts, tender annuals must wait until the danger of frost has well and truly passed. This guide aims to provide a framework for making these critical decisions.
When Is 'Now' for Planting Seeds?
The concept of 'now' for planting is fluid, adapting to the turning seasons. In temperate climates like much of the UK, 'now' could mean preparing for spring, mid-summer, or even the depths of winter for certain hardy varieties. Generally, we can break planting windows down into key periods:
Spring Planting (Late Winter to Late Spring)
This is a primary sowing season for many gardeners. From late winter onwards, you can begin sowing seeds indoors for plants that require a head start, such as tomatoes, peppers, and aubergines. As early spring progresses, hardy vegetables like peas, carrots, spinach, and radishes can be sown directly into prepared soil, especially in milder regions. Towards late spring, once the risk of frost is minimal, tender crops like beans, cucumbers, and courgettes can follow. For flowers, many annuals like marigolds, zinnias, and cosmos are sown indoors early on, with outdoor sowing happening as the soil warms.
Spring bulbs, such as tulips and daffodils, are typically planted in the autumn. However, if you're looking for flowers to plant now (in spring) from seed, consider fast-growing annuals that will bloom within a few months.
Summer Planting (Early Summer to Late Summer)
While much of the focus is on established growth, summer still offers planting opportunities. Early summer is ideal for sowing fast-maturing crops like lettuce, radishes, and certain types of beans for a subsequent harvest. Towards mid-to-late summer, you can sow seeds for crops that mature quickly and can withstand cooler autumn temperatures. This includes certain varieties of spinach, rocket, and quick-growing oriental greens. This period is also crucial for planting autumn-flowering bulbs and for sowing seeds of plants that provide late-season colour, like chrysanthemums or asters, often sown indoors earlier and transplanted out.
Autumn Planting (Early Autumn to Mid-Autumn)
Autumn offers a unique window for planting. For hardy vegetables, this is the time to sow seeds that will establish roots before winter and provide an early harvest next spring. Think of hardy brassicas like kale and Brussels sprouts, or overwintering onions and garlic (though garlic is often planted even later). This is also the prime season for planting spring bulbs directly into the ground, ensuring a spectacular display of colour come the following year. Many gardeners also use this time to sow green manures or cover crops to protect and enrich the soil over winter. For flowers, many biennials and perennials are sown in late summer or early autumn to establish themselves for flowering the following year.
Plants to plant in winter UK gardens can include certain hardy kale varieties, winter lettuces, and broad beans, sown in autumn to overwinter. Some gardeners also look at winter plants for pots that can be grown from seed sown earlier.
Winter Planting (Late Autumn to Early Winter)
Winter is generally a dormant period for seed sowing in most climates. However, in very mild regions, or for specific techniques, some sowing can occur. This might include sowing hardy peas or broad beans very late in the season to overwinter, or planting garlic. For those with protected environments like greenhouses, a wider range of seeds can be sown. Often, what is 'planted now' in winter refers more to the action of placing bulbs in the ground, or sowing seeds that will require a long, cool period before germinating in spring, sometimes called 'cold stratification' sowing.
The precise timing for sowing seeds is a dynamic interplay between your climate zone's temperature fluctuations and the specific needs of each plant species.
Always check the seed packet for specific sowing depths, spacing, and temperature requirements. These details are crucial for success, especially when dealing with marginal conditions.
Choosing What Seeds to Plant Now: Alternatives by Type
When considering 'what seeds to plant now', the choice often boils down to whether you're looking for vegetables, herbs, or flowers. Each category has specific needs and optimal sowing times.
Vegetable Seeds for Planting Now
Your choice of vegetable seeds depends heavily on the current season. If it's spring, you might be sowing peas, carrots, spinach, radishes, beetroot, and lettuce directly. Indoors, you'd be starting tomatoes, peppers, and aubergines. If it's summer, consider fast-growing beans, more lettuce, or rocket. For autumn sowing, look to hardy greens like kale, chard, and overwintering onions. If the current season is winter, you're likely focusing on planting garlic or overwintering crops in milder areas. The key is to match the vegetable's hardiness and growth cycle to the season ahead.
When thinking about what vegetables can I plant now, always consider your local average last frost date in spring and first frost date in autumn. This will inform whether you can sow directly outside or need to start seeds under protection.
Herb Seeds to Consider
Herbs offer a versatile addition to any garden and many can be grown from seed. In spring, basil, parsley, coriander, dill, and chives are popular choices for direct sowing or indoor starts. Many perennial herbs like mint or oregano can also be grown from seed, though they might take longer to establish. Summer sowing might include more basil or dill for successive harvests. In autumn, some hardy herbs can be sown for overwintering, such as parsley, and some gardeners sow chives or mint seeds in cooler conditions for a slow start. For those in milder climates, even some tender herbs can be sown in early autumn for a winter harvest indoors or in a sheltered spot.
Flower Seeds for Seasonal Blooms
The world of flower seeds is vast, offering colour throughout the year. Spring is a prime time for sowing many annuals like sunflowers, zinnias, marigolds, cosmos, and petunias, either indoors or directly outside after the last frost. If you're asking what seeds to plant now for immediate impact or a swift bloom, focus on quick-growing annuals. Autumn might be the time for sowing seeds of biennials like foxgloves or sweet williams, which will grow through winter and flower next year. It's also when you sow many hardy perennials from seed, which will establish over autumn and spring. For a continuous display, succession sowing of fast-blooming annuals every few weeks in spring and early summer is an effective strategy.
For those wondering about flowers plant in autumn, this typically refers to sowing seeds of plants that will bloom next spring or summer, or planting bulbs that bloom in spring.
Preparing for Success: Soil and Conditions
Regardless of what seeds you choose to plant now, preparation is paramount. Healthy soil is the foundation for vigorous plant growth. Before sowing, ensure your soil is well-drained and free from weeds and large stones. For direct sowing outdoors, lightly fork over the soil to a depth of about 15-20 cm, breaking up any clods. Incorporating organic matter, such as compost or well-rotted manure, will significantly improve soil structure, fertility, and water retention, providing a nutrient-rich environment for your seeds.
Sowing Indoors vs. Outdoors
The decision to sow seeds indoors or outdoors depends on the seed's specific requirements and your local climate. Seeds that require a longer growing season, are sensitive to cold, or are slow to germinate are often best started indoors. This typically involves using seed trays, pots, or modules filled with a specialised seed-starting compost, kept in a warm, bright location. Once seedlings have developed their first true leaves and the risk of frost has passed, they can be 'hardened off' – gradually accustomed to outdoor conditions – before transplanting into their final growing positions. Conversely, hardy seeds that tolerate cooler soil temperatures and shorter growing periods can be sown directly into the garden soil when conditions are favourable.
For bulbs to plant now (if 'now' is autumn), these are almost always planted directly into the soil, though container planting is also an option. The depth and timing for bulb planting are critical for their establishment and subsequent flowering.
When sowing small seeds, avoid the temptation to sow too deeply. A general rule is to sow seeds at a depth no more than twice their own diameter. For very fine seeds, simply pressing them onto the surface of moist compost is often sufficient.
Understanding when to plant spring bulbs or when to sow vegetable seeds for a specific harvest requires careful observation of your local weather patterns and an awareness of the typical growing season length in your area. By aligning your planting schedule with these natural rhythms, you significantly increase your chances of a bountiful and beautiful garden.
If you're considering what to plant in march, for example, this will differ significantly from what to plant in august. March might be about starting tomatoes indoors and sowing hardy peas outside, while August could be for planting garlic, sowing winter spinach, or planting spring bulbs. Always check specific advice for your region and the current weather outlook.
