I have seen some lists going around for planting that are incorrect or may contain dates which don’t apply to all parts of the world. Although it is difficult to make a list that applies to every climate I felt that this list would be helpful to most people in most places.  To make the most of this information find your last average frost date

This list is referring to when to plant in the ground or in a pot or raised bed outdoors. Some things such as tomatoes, peppers, and eggplant are best planted as a plant and others such as peas, beans, and corn are best planted as a seed directly into the ground. If planting indoors you may plant whenever you want.

Remember to add good quality compost before planting. I have added  compost to my Square Foot Garden beds and then planted cabbage (which I started indoors from seed), peas, lettuce, and arugula. In containers use good quality potting soil – not garden soil.

When you see something under two headings it is because it can be planted at either time.

Succession plant: Plant multiple crops, one after the other, to get a longer harvest.

Early Spring – as soon as the soil is workable (you don’t get to actually play in the mud when planting). In my area beginning 2 – 2/12 months before the last average frost date.
