![]() And for outdoor tomato types, you might even need to wait until early May, so that all risk of frost has passed by the time you plant them outside. For unheated greenhouses, waiting til March or April might be more appropriate. If you’ll be moving them to a heated greenhouse, or you live somewhere very warm, you might be able to sow them as early as February. ![]() When to transplant tomato seedlings from seed tray to potĮvery tomato grower’s aim should be to try and sow their tomato seeds about 6 weeks before their final location will be ready to take them. Starting seeds in a low-nutrient potting compost and transplanting them into a richer substrate later enables them to get started in ideal conditions, and produce the kinds of crops we want. It takes a lot of energy and nutrients to do that, but overly rich soil inhibits tomato seed germination. Modern cultivars produce fruit many times bigger than the original wild tomato plants. Sowing tomato seeds individually in large pots is a waste of space and potting compost – starting in seed trays and only potting on the strongest seedlings at each stage allows us to use our resources more efficiently, save money, and grow more crops!įinally, adult tomato plants are greedy. No plant seeds have a 100% germination rate, and some which do germinate will be weak and spindly. Sowing tomato seeds in seed trays and potting them on also helps us to grow more efficiently. More advantages of transplanting seedlings And our plants would never reach the point of bearing ripe fruit. For those of us in more northerly regions, if we waited until night time soil temperatures reached those thresholds, there simply wouldn’t be enough of the growing season left. And the seeds need to reach temperatures of at least 50f and ideally 65-85f just to germinate. ![]() As a result, they’re adapted to thrive in a long, warm growing season. ![]() Wild tomato plants were originally native to Ecuador and Peru, on the west coast of South America. Since most of us grow tomatoes in a climate which is far removed from the one they originally adapted to, this sequence of transplanting tomato seedlings makes it possible for us to provide optimum growing conditions at each growing stage. Starting tomato seeds in seed trays and transplanting them into small pots before finally planting them in their final location is a well-established routine for any tomato grower. Why transplanting tomato seedlings is a good idea Let’s see how that applies to transplanting them. In this video no-dig gardener Charles Dowding talks about the importance of timing when it comes to transplanting tomato seedlings. ![]()
