TRANSPLANTING SEEDLINGS HOW TO
How to plant out By April or early May, after the last frost in your area, and once your seedlings have grown strong and sturdy, it’s time to plant them into their final positions in the garden: Firm the compost gently around the seedling and water in, taking care not to damage or dislodge the seedling.Use the dibber to make a hole for the seedling in its new pot of compost, and lower the seedling in place.Try to keep as much compost around the roots as possible. Lift it out of the compost, holding it carefully by a sturdy leaf, not the delicate stem, while supporting the roots with the dibber.Use ‘dibber’ (a stick, pencil or similar) to loosen the compost around the first seedling.Fill several 9cm (3½in) pots or modular trays with peat-free multi-purpose compost.They can also become spindly and weak (leggy) as they strive upwards for more light and space. Their roots become intertwined too, making it more difficult to separate them without damage. Seeds sown singly in modular trays don’t need pricking out – simply move each seedling into a 9cm (3½in) pot once its roots have filled its module.ĭon’t delay pricking out, as overcrowded seedlings are more prone to fungal diseases, such as damping off. Perennials - such as delphiniums and echinacea, although these may not flower in their first summer.Annual climbers - such as morning glory and sweet peas.Hardy annuals and veg - to give them a head start, such as sunflowers and broccoli.Half-hardy annuals - such as cosmos and nasturtiums.Tender crops - such as tomatoes, chillies and courgettes.You can sow a wide range of seeds indoors, including: Ensures success - Particularly if you only have a few seeds, or they are rare or expensive.Additional time - Sowing indoors gives slow-growing plants the additional time they need to flower or crop.Head start - If you want earlier crops or flowers, sowing seeds indoors gives you a head start.Safeguarding - To provide additional protection, perhaps from slugs or damp weather.Frost-free conditions - Some plants need warm conditions to germinate and grow, such as tender and half-hardy flowers and vegetables.You’ll also need space in a greenhouse or on a bright windowsill to keep them until they’re ready to be moved outdoors. Sowing seeds indoors is easy and fun, but do bear in mind that the seedlings will need regular care for several months.
