Starting Plants from Seeds As spring progresses in the northern half of the world, stores are offering gardeners many choices for seeds. Starting a garden from seeds, rather than buying young plants, is a low-cost way to enjoy many kinds of flowers and food crops. Looking through catalogs that offer mail-order seeds is one way to get them. Choosing seeds from racks at local nurseries or garden centers is another way. Starting plants seeds Jessica Damiano writes about gardening for the Associated Press. Here is what she says about starting plants from seeds: In April, there is enough daylight to start garden seeds without the aid of electric lights. Some seeds can be planted directly in the garden. Others will have to be started in containers inside the home or under a shelter. Many people have the opinion that you are not a real gardener unless you start at least one thing you grow from seed. You can always buy young plants already growing at the store, but seeds give you the right to say you know how to grow a plant from the beginning. The cost is also far lower. In fact, starting seeds is easy. Everything the plant needs to germinate, or start growing, is in the seed. All you have to do is put it into soil that is a little wet and not let the soil dry out while the seed does its thing. If there are any special requirements, they are usually printed in the simple directions on the back of every seed container or packet. The one thing you might not find in those instructions is the suggestion to put mycorrhizal fungi around larger seeds or to put a little on smaller seeds. You should be able to find these special fungi where you buy seeds. Fungi are a form of life that is neither plant nor animal. Mushrooms are among their common forms. Mycorrhizal fungi are special. They form a symbiotic relationship with some plants and help provide water and nutrients to them. Many nurseries now carry two kinds. They are called endomycorrhizal and ectomycorrhizal fungi. Annual plants -- ones that grow for one season -- and many garden crops associate with endomycorrhizal fungi. Some plants do not need them at all. This includes members of the cole family: cabbages, kohlrabi and kale. Broccoli and cauliflower also do not use fungi. So, you do not need to add it. Besides fungi, Damian warns against soaking your seeds in hydrogen peroxide, as some experts often suggest. There are bacteria living on all seeds that are supposed to be there. Peroxide will kill them. The bacteria have developed to help in germination and growth. They also put microorganisms into the soil that work in partnership with many plants. Planting big seeds is easy, and it is a good idea to get the assistance of young people to help in the job. Very small seeds, like celery seeds, need a little equipment. Put the tip of a pencil in water and then use it to pick up each seed. It will hold one seed as you put it into its starting container. When choosing containers to start plants, Damiano advises against buying new plastic ones. She suggests using any old plastic containers or using newspaper or cardboard. You can use egg containers or anything that is available. But remember to put drainage holes in each one. If you do not add holes, water can build up in the bottom and cause the seeds to rot. Damiano reminds growers that it would be a shame to grow something in a container and then forget what it is called. Write the names of all your seeds on the containers you are growing them in. And it is never too early to think about the next growing season. Once you have established plants in your garden, consider letting some "go to seed." This means you are growing them for their seeds, not for crops. That way you will have your own seeds for next year's garden, and you will not have to buy them at all.
