When is 'Now' for Planting Perennials?
The timing for planting perennial plants to plant now hinges significantly on your local climate and the specific plant's hardiness. Generally, the most forgiving periods for establishing perennials are autumn and early spring. Autumn planting allows roots to establish over winter, benefiting from natural moisture and cooler soil temperatures, leading to a strong start in spring. Early spring, once the ground is workable and the risk of severe frost has passed, is also an excellent opportunity. Planting now, whether it's late autumn or early spring, ensures the plants have adequate time to develop before the stress of summer heat or winter's deep chill.
The crucial factor is soil temperature and moisture. Roots need to be active enough to grow, but the plant shouldn't be under extreme environmental stress. If you're considering what to plant now in autumn, focus on species that can tolerate damp soil and cooler conditions, preparing them for the following year. Conversely, if you're looking at what to plant now in spring, you have a broader range of options, including many that might have been too tender for winter planting. Understanding your region's last frost date and typical rainfall patterns is paramount to successful planting, ensuring your chosen perennial plants to plant now thrive.
For many gardeners, 'now' often refers to the current season they are experiencing. If it is spring, then perennials to plant now are those that can establish quickly and withstand potential late frosts. If it is autumn, then perennials to plant now are those robust enough to overwinter and be ready for spring growth. The goal is always to give the plant the best possible conditions for root development before the extremes of the growing or dormant season.
- Plant perennials in autumn or early spring for best root establishment.
- Soil temperature and moisture are key indicators for planting time.
- Consider your local climate and frost dates when deciding what to plant now.
- Autumn planting aids overwintering, spring planting offers broader choices.
Hardy Perennials to Plant Now for Autumn/Spring Success
Selecting the right perennial plants to plant now can transform your garden into a resilient and beautiful space. For those looking to plant in autumn or early spring, certain varieties consistently perform well, offering reliable blooms and structure year after year. These are plants that tolerate cooler soils and can establish a strong root system before facing summer's heat.
Consider the enduring charm of hardy Geraniums (Cranesbill). Varieties like Geranium 'Rozanne' offer an exceptionally long flowering season, from late spring well into autumn. They are relatively unfussy, thrive in a range of conditions from full sun to partial shade, and once established, require minimal care. Planting these now ensures they settle in for a spectacular show next year. Similarly, Hostas are invaluable for shady spots. While primarily grown for their striking foliage, many also produce elegant flower spikes. Planting them now, especially in autumn, allows their extensive root systems to develop undisturbed, leading to lush growth.
For a splash of colour, Echinacea (Coneflower) is a superb choice. These are robust plants that attract pollinators and offer beautiful, daisy-like flowers. They prefer sunny positions and well-drained soil. Planting them now, either in autumn or early spring, gives them the best chance to establish before summer. Another excellent option for structure is ornamental grasses. Varieties such as Hakonechloa macra 'Aureola' (Japanese Forest Grass) or the upright Calamagrostis x acutiflora 'Karl Foerster' add movement and texture. They are exceptionally hardy and can be planted successfully in both autumn and early spring, providing year-round interest.
When considering what to plant now, especially if you're aiming for early spring colour, think about plants that provide a foundation. Heucheras (Coral Bells) offer stunning foliage in a myriad of colours – from deep purple to lime green – and delicate flower stalks. They are ideal for borders and containers and thrive in partial shade. Planting them now allows their vibrant leaves to provide immediate impact and ensures they are well-rooted for the growing season ahead. These reliable performers are perfect perennial plants to plant now for sustained garden appeal.
For those seeking blooms earlier in the year, consider planting spring bulbs like Daffodils, Tulips, and Crocus in autumn. While technically bulbs, they offer perennial blooms year after year. When planting bulbs to plant now in autumn, aim for well-drained soil in a sunny or partially shaded spot. For spring planting, you might look at options that tolerate cooler soil, but the established planting windows are autumn for bulbs and early spring/autumn for most perennials.
The key to success with perennial plants to plant now is selecting varieties suited to your soil type and light conditions.
What Vegetables Can I Plant Now for a Harvest?
While the focus is often on flowers, many gardeners also wonder what vegetables can I plant now for a harvest, particularly when considering early spring or late autumn planting. The answer depends heavily on your climate zone and the specific vegetable's requirements for temperature and daylight. However, several robust vegetables can be planted at these transitional times of year.
For autumn planting, if you're in a milder climate, you might still have time to sow hardy greens. Spinach, kale, and certain types of lettuce can often be planted in early autumn for a late harvest or overwintering. These are plants that can tolerate cooler soil and even light frosts. Radishes are also quick growers that can be sown in early autumn. If you're in a colder region, autumn planting might be more about preparing for spring. However, certain hardy root vegetables, like parsnips and some varieties of carrots and leeks, can be sown in late autumn for overwintering and early spring growth. These benefit from the soil being cold to break dormancy properly.
When it comes to what to plant now in spring, the options expand considerably. Peas and broad beans are classic cool-season crops that can be sown directly into the ground as soon as the soil is workable. These are excellent choices for early spring planting, providing a nutritious harvest relatively quickly. Potatoes can also be planted in early to mid-spring, depending on your last frost date. Different varieties have different maturity times, allowing for a staggered harvest.
Brassicas like broccoli, cauliflower, and cabbage can often be started from seed indoors earlier in the spring and then transplanted out once the risk of hard frost has passed. Alternatively, you can purchase young plants from a garden centre. Onions and shallots, typically planted from 'sets' (small bulbs), are also a staple for early spring planting. Their growth is less sensitive to minor fluctuations in temperature once established.
Carrots, beetroot, and turnips can also be sown directly in spring once the soil has warmed sufficiently. For those interested in what to plant in March specifically, this is often the ideal time to sow hardy peas, broad beans, spinach, and direct-sow carrots and parsnips in many UK gardens, provided the soil is not waterlogged. Always check local planting calendars, but generally, spring offers a wide array of vegetables to plant now for successive harvests throughout the warmer months.
If planting vegetables in autumn, consider using cloches or fleece to protect young seedlings from harsh weather and extend your harvesting season.
Planting Perennials in Pots: Winter Plants for Pots & Spring Colour
Container gardening offers a flexible way to enjoy perennial plants, especially for those with limited garden space or who wish to move plants around for optimal display or protection. When considering perennial plants to plant now for pots, selecting the right varieties and understanding their needs is crucial. Many plants that thrive in the ground can also flourish in containers, provided they have adequate drainage and the right soil mix.
For year-round interest in pots, particularly looking for winter plants for pots, evergreen perennials are ideal. Skimmia japonica, with its glossy leaves and bright red berries (on female plants, if a male is nearby), provides colour and structure even in the coldest months. Heucheras, already mentioned for borders, also perform admirably in containers, their colourful foliage a welcome sight. Dwarf conifers and ornamental grasses can also provide evergreen structure and texture in larger pots.
When planting perennial plants to plant now in spring for pots, you have a vast selection. Consider plants that offer sequential flowering. For example, early spring might see Polyanthus or Primroses, followed by blooming Geraniums, Salvia, and later, Chrysanthemums for autumn colour. Lavender is another superb choice for pots, thriving in sunny, well-drained conditions and offering fragrant blooms and foliage. Ensure your pots are sufficiently large to accommodate the mature size of the plant and that they have drainage holes. Using a good quality potting mix that retains moisture but drains freely is vital; avoid using heavy garden soil, which can become compacted.
For those aiming for immediate impact or specific seasonal displays, think about what to plant in August or September for autumn and winter interest, or what to plant in March for spring and summer blooms. Perennial bedding plants are often available in spring, offering instant colour. However, for long-term success, establishing perennial plants to plant now for their root systems to develop is key. This applies whether they are in the ground or in containers. With careful selection and appropriate care, containerised perennials can bring colour and life to patios, balconies, and doorsteps throughout the year.
Choosing pots with adequate drainage is non-negotiable for healthy perennial growth.
Caring for Your Newly Planted Perennials
Once you've selected and planted your perennial plants to plant now, proper care is essential to ensure they establish well and provide years of enjoyment. The immediate aftermath of planting is a critical period. Ensure the soil is gently firmed around the roots to remove air pockets, and water thoroughly. This initial watering helps settle the soil and reduces transplant shock. The frequency of watering will depend on the weather and the specific plant's needs, but generally, newly planted perennials require consistent moisture, especially during dry spells, until they are well-rooted.
Mulching is a highly beneficial practice after planting. Apply a layer of organic mulch, such as compost, bark chippings, or well-rotted manure, around the base of the plants. This helps to retain soil moisture, suppress weeds (which compete for water and nutrients), and regulate soil temperature, protecting roots from extreme heat or cold. Keep the mulch a small distance away from the plant's stem to prevent rot. This simple step significantly aids the establishment of your perennial plants to plant now.
Deadheading spent flowers, while often associated with summer care, can also be beneficial for plants put in during autumn or spring. For plants that might attempt to set seed too early, removing faded blooms can encourage the plant to put more energy into root development and vegetative growth rather than reproduction. This is particularly true for perennials planted in spring. For plants installed in autumn, allow them to go to seed or die back naturally; this can provide winter interest and food for wildlife.
Weeding is an ongoing task. As mentioned, a good mulch layer helps, but it's important to keep the area around young plants free from competitive weeds. Gently remove any weeds that appear, being careful not to disturb the delicate roots of your new perennials. Over time, as the perennials grow and spread, they will naturally suppress weeds themselves, becoming more self-sufficient.
Monitor your new perennial plants to plant now for any signs of stress, pests, or diseases. Early detection means a swifter, simpler solution.
