Indoor-grown plants are highly shielded from wind and temperature fluctuations, as well as other environmental stressors. Gradually acclimating plants to challenging conditions triggers them to become stronger at a cellular level.Cell walls are strengthened as they recognize the slight changes in temperature, humidity, and the pressure of slight winds over increasing periods of time. To harden off your seedlings simply set them outdoors for a few hours a day. Over the course of 1-2 weeks increase how much time they spend outside in a day until they are able to sit out overnight. When you first start the process, you may notice the young tomato seedlings appear slightly wilted or weak. This is normal. Taking them back inside to the safe environment will enable them to recuperate prior to braving outdoor elements the following dayTRANSPLANTING Transplant tomato seedlings outdoors in a sunny spot as soon as the soil has warmed and after all danger of frost has passed.

Make sure to plant outdoors after the final frost of the season.(you can Find USDA plant hardiness zone here) You may also use a seed starter tray and transplant the seedlings once they’ve grown to an appropriate size. Because they can grow extremely tall, indeterminates will need robust trellises or wooden stakes for support. How to prune indeterminate tomatoesVining tomatoes require regular pruning. Pinch back suckers, trim stems and leaves for sunlight and airflow.Harvesting indeterminate tomatoesIndeterminate tomato plants provide growers with a consistent fruit supply throughout the entire season. These varieties ripen later in the season due to their growth patterns. Therefore, plants may produce fruit well into late summer or early autumn, necessitating attention to nightly temperatures.Harvest fruits when fully ripe; in case of frost danger, pick even if green.
