Tomato seed sowing is simple. Sprinkle the seeds over the top of the pot.
Tomato seed – fuzzy little things with so much potential if handled properly
But – this is the first time you can make a small mistake so do this task carefully.
Space the seeds out. Do not lump them into a single area of your soil area.
Try to leave at least one half inch between each seed. Now I know the seed package has three gazillion seeds and you can only fit 25 seeds into a pot but don’t let temptation override your common sense; if you over seed, the seedlings will not grow properly. It is much better to plant several pots than over seed.
Also, excess seed will likely store for another year if it is kept dry and cool so they don’t have to be used up this year.
Overcrowding seedlings leads to disease and weak spindly plants that are not much good in the garden. I note that with excess seeds, there is no reason why the smaller gardeners among us can not be given their own pot for seed starting. (Marigolds make the best and easiest plant for small children as they are easy, fast and fairly tolerant of over-loving)
Once sown, seeds like uniform moisture.
While there are a few exceptions to this, gardeners can lightly cover most seedlings to create pockets of moisture around their seeds.
Lightly cover does not mean deeply bury. While many garden seeds such as peas and corn can grow through one half inch of soil, if a small geranium or petunia seed is planted that deeply, the gardener might just as well put a grave marker on the seed pot rather than an identification tag.
With the exception of the seeds such as pansies that demand full darkness for germination, I cover my seeds so that they are just hidden, with no more coverage than necessary and certainly no more than the width of the seed.
All I want to do is ensure a uniform moisture level around the seed for uniform seed starting and soil surrounding the seed will reduce drying air currents. Make sure the artificial soil you’re using is fine (no lumps in the seed covering soil) and just sprinkle it over the seed. Pansies and other “dark” germinators that demand darkness for germination get covered slightly deeper to restrict light levels or are covered with black plastic for 7-10 days to induce germination.
Once covered, I stick a plant marker into the pot to tell me what’s in there. The older I get, the more plants I grow, the more determined I am to label every seed starting pot.
