Cerise tomato seeds from Johnsons produce small red cherry tomato with a sweet flavour and steady cropping habit. They can be grown in a greenhouse or outdoors, depending on the season. These plants need support as they grow, otherwise they sprawl and become harder to manage. Cherry tomato seeds for greenhouse or outdoors These seeds suit both greenhouse and outdoor growing in the UK. In a greenhouse, you will usually get a longer cropping window. Outdoors works well in a decent summer, but in cooler or wetter seasons, the crop can be smaller. That is the reality of it. Sow from January to March for greenhouse crops, or from March to April for outdoor crops. Seeds need warmth to get going, around 15 to 20°C. In a chilly room, germination can drag on a bit and some trays take their time. How to sow cherry tomato seeds Sow thinly in seed compost, trays, pots or grow bags, then cover with a fine layer of compost. Firm gently and keep moist. Seedlings usually appear within 7 to 14 days. Once seedlings appear, transplant them into their growing position in a tomato grow bag or tomato growpots from April to May. Keep them somewhere bright and warm. Outdoor tomato growing and plant support For outdoor crops, stand plants outside for a few days in late May before planting out, and avoid frosts. Pick a sunny spot. These plants need support with canes or tomato supports, and side shoots should be pinched out regularly. Leave them unchecked and they soon turn into a tangle. Watering and feeding cherry tomato plants Keep the plants moist and weed free as they grow. Apply a liquid feed every 2 to 3 weeks once the first trusses have set. In warm weather, grow bags dry out faster than many people expect, so watering can become a daily task. Using tomato growpots make them easier to feed and water. Harvest time for Cerise cherry tomato For greenhouse crops, harvesting usually runs from June to October. Outdoor crops are often at their best in August. The fruit tends to ripen in clusters, and regular picking helps keep the plant producing over a longer period. All Cerise tomato seeds are grown using strictly organic methods. That refers to how the seed is produced. It does not remove the need for normal growing care once you sow them at home. FAQs Do I need a propagator to start these seeds? No, but it helps keep the temperature steady, which can improve germination. Can I grow Cerise tomato on a patio? Yes, as long as the plants get plenty of sun and have support. Why are my seedlings tall and weak? Usually because they do not have enough light. Early sowings can do this quite easily. Can I sow these straight outside? It is not the usual method in the UK. Indoor sowing gives better control early on. When should I start feeding the plants? Once the first trusses have set, start liquid feeding every 2 to 3 weeks.
