Well first off, I'm not super serious about growing. I just have some seeds that look mature and since it's summer I've decided I want to go outside and just plant them and see what happens. How long will they take to start sprouting? I planted some in April and has been a strange mix of hot, mild, and rainy. Temps in the 40's to 70's probably. I'm in Indiana btw. But do those ones still have a chance? It's been over a month and I haven't seen anything yet. I think maybe the conditions killed them. But now that summer is really here, it will be much warmer, I just want to try to bury some seeds again and see what happens. Is there anything wrong with that? They should grow?
before you bury any more, you may want to consider sprouting them indoors and letting them grow for a week or two before you place them outside. Give them a good chance at growing. Im not sure what the ground is like around there, but you will want to mix in some potting soil with the dirt, like a 5 gallon bucket sized hole. Since they're outdoors they may grow very big and will need the good soil. You could just take an old plastic pot and fill it with soil then stick that in the dirt, should keep out any neighboring roots and keep in the good soil.
usually a healthy seed will sprout in 5-14 days. saoking the seeds in room-temperature water for 2-4 hours before planting can reduce this time by a day or 2.as mentioned, sprouting indoors is best so that you can transplant the succesful seedings into the desired formation, rather then having a "patchy" crop because some sprouted too close or too far apart.
Once germinated watch out for slugs and snails they love juicy seedlings. Your better starting them in a pot with copper tape around it. Then cut the bottom out of the pot and put in the ground.
