I usually start seeds at the beginning of April. Maybe a little earlier. I probably should start the peppers earlier this year as they didn't set much fruit in 2017. Early April is good for the brassicas. That's the cabbage, broccoli, and sprouts. Of course that means you needed to buy seeds before this time. The local nurseries and the home centers usually have seeds for sale in March. I order most of mine through the mail. If you aren't sure where to buy just key in "seeds" or "vegetable seeds" to your favorite search engine and you will get millions of hits. You might have to use more than one seed company depending on what varieties you want to plant.
|Washing "Pots" from Last Year|
If you reuse your 1020 trays from last year and your 4 or 6 packs, be sure to wash them in soapy water. Add about a quarter cup of bleach. Be careful what soap and bleach you use together. A soap containing ammonia should not be used with bleach. That would put off a poisonous gas that is not good for you. Washing will help get rid of any critters that might have taken up residence. The critters include the ones you can't see. There are bacteria and fungi that you don't want in the soil while starting your seeds. Wash last years supplies and they should be fine.
When the sprouts appear discard the plastic wrap. You should check to see if they need water every day. Don't let them dry out. The plants are pretty fragile right now. You will also need a more intense source of light. I use fluorescent lights because I have them. You could use LED as well. More on lighting a little later.
