Vegetable Gardening Basics for Containers and Beds

Vegetables are simply plants with a job to do, and most of them reward the same things: strong light, rich soil, steady water and enough space. Get those four right and the rest follows. 100% Local

Start with light and soil

Most fruiting vegetables — tomatoes, peppers, cucumbers — need six to eight hours of direct sun. Leafy crops such as lettuce tolerate less. Use a rich, well-draining mix and containers large enough that roots are not cramped; small pots dry out too fast in summer.

Spacing and planning

Spacing controls airflow, which in turn reduces disease. Crowded plants compete for light and water and are more prone to mould. Plan the bed or pot before sowing so each plant has room to reach its mature size.

Give vining crops a support or a large pot of their own.
Group plants with similar water needs together.
Rotate crops between beds each year where possible.

Watering

Water deeply and less often to encourage deep roots.
Aim at the soil, not the leaves, to reduce disease.
Check containers daily in hot weather — they dry out fast.
Mulch the surface to slow evaporation.

Feeding

Leafy crops want more nitrogen for green growth, while fruiting crops need phosphorus and potassium once they flower. Feed container plants more often than those in open ground, since nutrients wash out of pots with every watering.

Common mistakes

Sowing too early before the soil has warmed.
Planting too close and then being unable to thin.
Letting containers dry out completely between waterings.
Ignoring pests until they are established.

Start with a few reliable crops, learn how they behave in your space, and expand once you know what your light and season allow.

Frequently Asked Questions

What size pot do vegetables need?

It depends on the crop. Leafy greens manage in a small pot, while tomatoes, peppers and cucumbers need a large container, often twenty litres or more, so the roots have room and the soil does not dry out daily.

Can I grow vegetables in shade?

Leafy crops such as lettuce and spinach tolerate partial shade, but fruiting vegetables need full sun to produce well.

How often should I feed containers?

In the growing season, roughly every two weeks, since nutrients wash out of pots with each watering.

Succession sowing for a longer harvest

Rather than sowing a whole packet at once, sow small amounts every two or three weeks through the season. This spreads the harvest over months instead of leaving you with a glut followed by nothing. Fast crops such as lettuce, radish and green onions respond especially well to succession sowing, and it also means a failed sowing costs you only a couple of weeks rather than the whole season.
