Tip number 2:
For young plants or plants with new leaves, it is always a good idea to acclimate them. This is especially true for your new seedlings. When you bring your plants out, start them in full shade a few hours a day and gradually work them into the environment that will be their summer home.
Tip number 3:
If you live in the north, consider freezing temperatures. Many plants DO NOT tolerate frost! Don’t kill your seedlings and push your garden back weeks of time! The best thing to do is to understand your plant and know what it tolerates and needs. Some plants like orchids need to be stressed out by cool temperatures to flower though. So just look up what you have so you can be prepared to take the best care of it.
Tip number 4:
Potting soil and mulch gradually decompose adding organics to your soil. When you move your plants, this is a great time add fresh material back to the top of your pots.
Tip number 5:
Consider repotting your plants at this point as well. As plants grow, they may need larger pots to live in. It is better to repot them in the spring than in the middle of summer when they are stressed by heat, dryness, or are in the process of flowering or bearing fruit.
