““Plant transplants outside according to the spacing the fully grown plants will need. Pay attention to the depth of the hole, and ensure that you don’t bury the stem in the soil (except in special cases—see Growing Tip on the following page). Take the temperature of the soil to make sure it is warm enough. (The soil should be at least 60 to 65 degrees F for planting warm-weather vegetables such as tomatoes or peppers.) Before planting any transplants outside, prepare them by hardening them off. GROWING TIP Tomato plants should be planted deep. Strip off all but the top four sets of leaves. Plant the entire rest of the plant below the soil line. Tomato plants will grow roots from the stem, making them stronger and healthier. Hardening off before Planting out Vegetable transplants grown inside a greenhouse (or your house) need to be hardened off (acclimated to the change in temperature and light) before they’re planted outside. Even if you buy plants that were sitting outside at a garden center, it’s a good idea to harden them off before planting. For all you know, the plants were taken from the greenhouse, loaded on a truck, and brought to the garden center on the same day you saw them sitting outside. How to Harden Off Transplants 1. Place plants in a sheltered location such as a porch or patio for the day, and bring them in at night. Do this for three or four days. 2. Next, leave them outside all day in the protected location. Do this for about a week. Don’t forget to water while you’re doing this! 3. Finally, move the plants from the sheltered location (the porch or patio) to a more exposed location (the front sidewalk or driveway). Leave them there for three or four days. 4. Wait for a cloudy day (if possible) and plant your plants in the garden. Planting out on a cloudy day will lower the stress that the plants experience.””
