Novice and experienced gardeners alike must take extra care to determine the optimal time to plant seeds. If you plant warmth-loving seeds or transplants outside too early in spring, the cold soil and air temperatures may harm them. On the other hand, crops that do best in cooler weather may not thrive if they are planted late and end up maturing when the weather is too hot.
Although we've done the math for you in our interactive calendar, learning the calculations used to create a planting calendar for seeds is a very practical and useful skill for your young gardeners. Discover the technique in our Creating a Planting Calendar Lesson Plan.
