Start each year with fresh seeds. And make sure you read the packages carefully. Some be sown directly in the garden which is the easiest way. (We all love these seeds.) But it helps to give others, such as broccoli and cabbage, a headstart by growing transplants indoors.
It helps to have a tray called a flat. But there are those of us who are a little bit more financially savvy. You can use paper cups or even tin cans. Just make sure you poke some holes in the bottom of the container so excess water can drain away.
Make sure you label those seed containers with the name of the seed and the date it was planted. Some seeds take a little longer to grow. And your seed packet should give you a little information on how long you have to wait.
When the seedlings start to grow, the first leaves (called seed leaves) are oval or round. The next set of leaves (called true leaves) look more like the big leaves will. When these appear, remove the cover, and place the flat in bright light. Water ever other week.
If you planned ahead, the roots will have filled the container about the time that the weather is right for planting outdoors.
