I planted a number of things the other day, one of which was three cucumber plants. Not only did two of them get eaten by something, probably a groundhog, but it was way too early. So I went online and found that I can start the seeds right in the garden once the soil is warm and after the danger of frost has passed. I made the mistake of thinking they are cool weather plants like the beans I put out. Oh well, I am still learning. There is a lot to remember in gardening. You have to remember most importantly to read the seed package and I would have done that except I was rushing about grabbing things and grabbed the cucumber plant mistaking it for a plant that can go out now.
The cool weather things that I can plant now are beans, peas, lettuce, broccoli, radishes, beets, and onions. There is a whole list of other things too, and you have to make sure that when you look online that you refine your search to your hardiness zone. I found a great site which has a whole list of the seeds you can plant for your zone. This helps a lot. This site also has a spreadsheet showing when to plant fall crops. Of course, since they are an online business you can order seeds from them too, but for now I am going to depend on their charts.
Of course even if I plant them on time at the right time, I still have the birds, squirrels, and groundhogs who are going to try and get to them first. That is yet another battle.
