Succession sowing spreads harvests by starting suitable crops in small batches. In a small vegetable garden, the aim is to match production to what you can eat and the space that will become available, rather than sowing the whole packet on one day.

Choose crops that benefit

RHS guidance highlights quick-maturing vegetables such as salads, carrots, peas and French beans. Regular batches can also help with crops that become less useful after bolting, including coriander, rocket and spinach, provided each sowing is suitable for the season.

Not every crop needs this treatment. Tomatoes and peppers can fruit for a long period from a single appropriate sowing, while some crops are grown for storage. Use a crop’s harvest habit to decide whether another batch adds value.

Begin with the harvest you want

Estimate a useful portion for your household and the length of row or number of plants needed. Start conservatively. It is easier to enlarge the next sowing than to find room for dozens of surplus seedlings.

Draw the bed or container layout and include mature spacing. An empty-looking space between young plants may already be needed by their later growth. Avoid filling every gap with another crop before checking light, root space and harvesting access.

Use intervals as a starting point

Seed packets and crop guides give useful seasonal windows, but a fixed interval is not a guarantee of evenly spaced harvests. Growth accelerates or slows with temperature, light and moisture. Two sowings made weeks apart can become ready close together when conditions change.

Check the progress of the previous batch before repeating it. Record sowing and first-harvest dates, then adjust. Use varieties with different maturity periods where appropriate, but check that each is suitable for the time of year and your growing conditions.

Plan the handover between crops

Mark when a bed is likely to become free and allow time to remove residues and prepare the surface. Some crops can be raised in modules while an earlier crop finishes, whereas others are better directly sown. Follow the crop’s guidance rather than transplanting everything for convenience.

Have a fallback if a harvest runs late. A spare container or a smaller next batch is often better than planting into a crowded bed. Consider crop rotation and known pest or disease issues when selecting the replacement.

Keep a simple sowing record

A useful record has five entries: crop and variety, sowing date, intended planting space, expected harvest period and actual result. Add notes about bolting, weather or a batch that was larger than needed. These observations make next year’s plan more accurate.

During a holiday or a busy period, reduce the number of active batches. Succession sowing should make harvests easier to use, not create a constant queue of seedlings needing urgent attention. A few well-timed crops are enough to establish a productive routine in a small space.
