It’s important to take your time when it comes to moving your new seedlings to the great outdoors. This applies whether you grew your own vegetables and flowers from seed or bought them from a greenhouse. Moving your plants from the house or greenhouse directly into the garden without giving them time to adjust will mean you'll lose most, if not all of them. At the very least, you’ll set the plants back weeks due to transplant shock. This slow transition from indoors to the outside is called “hardening off”. Hardening off plants gradually exposes them to outdoor light, wind and temperatures. The process is easy, but it takes time. In fact, you should plan on a week or so to get your immature plants ready to transplant into the garden. On the first day, pick a sheltered, shady spot under a tree or on the patio and leave them there for 3 or 4 hours. Bring them in that night. The second day, leave them out 5 or 6 hours, the third day 6 or 7 hours.
