Direct Sowing Outdoors

Sowing

Direct sowing is a simple, economical way to grow hardy vegetables, annual flowers and green manures where they will mature. It avoids root disturbance and works particularly well for crops that dislike transplanting, such as carrots, parsnips, peas and many salad leaves. Success depends on warm enough soil, careful preparation and steady moisture.

How to do it

Choose an open bed with workable soil and remove weeds, stones and large clods. Rake the surface to a fine, level tilth, adding well-rotted organic matter earlier if the soil needs improvement. Make shallow drills with a cane or draw a straight line for wider sowings. Sow thinly at the depth and spacing on the packet, then cover gently and firm the soil with the back of a rake. Water with a fine rose if conditions are dry. Mark rows clearly, especially for slow-germinating crops. Once seedlings are large enough to handle, thin them to their final spacing, taking out weaker plants first and keeping the bed weed-free.

When to do it

Begin most hardy direct sowings from March, once soil is no longer cold and sticky. Make small repeat sowings through spring and summer for salads, beetroot, radish and peas. In northern or upland gardens, soil often warms later. Use a cloche to gain a little earliness where conditions are suitable.

Tips

Avoid working or sowing wet soil, as it compacts easily and forms a hard surface. Water rows before sowing in dry weather rather than flooding newly covered seed. Protect young seedlings from slugs where needed, and thin promptly. A short row sown every few weeks is often more useful than one large sowing.
