tomato cultivation methods
In most cases, tomato seeds should be started indoors 6-8 weeks before last Spring frost. Seeds can be direct seeded in reas with a long growing season. Seeds should be sown in flats or cell trays using a sterile seedling mix. Plant seeds to a depth of 0.6 cm (4 in) and water lightly. If cells are being used, plant several seeds in each cell and thin to 1 seedling after
germination. Position trays in a bright South facing window or under fluorescent lighting. The optimum soil temperature for germination is 21-32°C (70- 90°F). A heat mat can be used to warm the flats if required. Seedlings should emerge within 6-14 days and after the seedlings has developed the first set of true leaves then they can be moved to a larger (3-4 in) pot and moved to a cooler temperature (16-21°C/60-70°F). Tomato seedlings are ready to be transplanted once they are 15-25 cm (6-10 in) in height and have 3-5 true leaves assuming all danger of frost has passed.?
