If you're worried about being short of time, fear not – you can still grow and enjoy tasty tomatoes with little effort, even in pots and growing bags. In fact, tomatoes grown in growing bags and watered once weekly produced the biggest harvest, in our magazine watering trial.

Discover our top tips for getting a delicious crop of tomatoes with minimum effort, below.

Prepare your soil

Take time to fork manure and compost into your borders and greenhouse beds before planting to help conserve water through the growing season.

Grow in large containers

Choose as large a container as possible, if you’re growing tomatoes in a pot, to give your plants as much compost, water and nutrition as possible.

Use good-quality compost

Use a good-quality compost, such as John Innes No. 2, that won’t shrink or clump and will allow water to easily reach the plants’ roots.

Mix in water-retaining gel

Mix water-retaining gel into the compost before planting to increase its ability to retain water and to cutdown on the amount of watering needed.

Mulch your tomatoes

Mulch, particularly plants in pots, to conserve water in the soil – use gravel, pebbles, bark or compost.

Keep them well ventilated

Keep plants grown indoors well-ventilated – avoid overheating and keep air circulating by always opening vents on warm days and not overcrowding plants.

Water plants at the base

Water the plants directly at the base rather than over the foliage, to ensure that the water gets to the roots where it is needed and doesn’t cause fungal diseases.

Water thoroughly

Always water thoroughly. This is more important than watering every day and is definitely better than little and often.

Use automatic irrigation

Use automated irrigation systems to make watering easier if you are away from home a lot or pushed for time. They allow water to drip slowly onto the plants’ roots, often as part of a timer system.

Avoiding tomato blight

Prevent losing your crop to tomato blight by keeping tomatoes dry if planted outdoors, ventilated and by choosing blight resistant varieties like 'Lizzano' and 'Jasper'.
