Planting & Growing Tips
Plant Grosse Lisse tomatoes in well-drained soil in a full sun position. Keep plants well staked as they grow to support the stems and developing fruit. Installing the stake at planting time can also help avoid disturbing established roots later. Pinch out lower side shoots as they develop to help manage the plant's vigorous growth. Mulch around the root zone to help retain moisture and keep the roots cooler during warm weather. Water regularly and aim to maintain consistent soil moisture, particularly while flowers and fruit are developing. When watering, direct water around the root zone rather than regularly wetting the foliage.
Growing Grosse Lisse Tomatoes in Pots
Grosse Lisse tomatoes can also be grown in pots at least 30cm in diameter. Choose a container with good drainage, position it in full sun and provide a sturdy stake to support the plant. Container-grown tomatoes can dry out more quickly than plants growing in the ground, so check soil moisture regularly during warm weather.
Companion Planting
Tomato Grosse Lisse can be planted with basil, beans, carrots, chives, lettuce and parsley.
Frequently Asked Questions
When should I harvest Grosse Lisse tomatoes?
Harvest Grosse Lisse tomatoes when the fruit has developed its mature colour and feels ripe but still firm. Tomatoes that have begun to colour can also be picked and allowed to finish ripening indoors if fruit is at risk from birds, pests or adverse weather.
How can I help prevent Grosse Lisse tomatoes from splitting?
Keeping soil moisture reasonably consistent can help reduce the risk of tomatoes splitting. Avoid allowing the soil to become extremely dry and then giving the plant a large amount of water at once. Mulching around the plant can also help reduce rapid changes in soil moisture.
