I started my garden today--inside with seeds. I have 25 beefsteak tomatoes, 25 cherry tomatoes, 25 green bell pepper plants, 25 hot pepper plants (for the husband and a couple of daughters who like hot stuff), and a few garlic cloves.
Outside some garlic is trying to come up from last year, but I do wish it would hold off awhile longer.
I use the planting guide on http://www.sproutrobot.com/ to know when to plant what, but I don't order my seeds from them.
I also went on ebay and bought 25 strawberry plants. They should arrive in about 10 days.
Last week, I got a little portable greenhouse, which I set up in the dining room. It seemed to be the best location as it has a south window, and since we spend a good amount of time there, I will be able to keep an eye on the plants and remember to water them. I have my jiffy trays in there (although one seems to be missing...so I am using its top as a second tray). Since the greenhouse is a greenhouse, I won't need to have the lids on the trays this year.
You can make a greenhouse out of about anything--store bought cake/pie pans with the clear plastic lids are great.
