On a beautiful sunny afternoon in late May or early June, do some gardening.
Beans - Plant seeds 1 1/2 - 2" deep in soil. Harvest in 60 days.
Beets - Plant seeds 1/2" deep in soil. Harvest in 40-70 days.
Cucumbers - Plant seesd 1" deep. Cucumbers will creep over your garden, so don't plant anything else within 3 feet. Harvest in 2-3 months.
Peppers - Set the small plants (without fruit or flowers!) in warm soil 1/2" deep. If the soil is too high in nitrogen, then you will end up with lots of plant and few peppers. Don't plant them next to other nightshades ( tomatoes, eggplant, etc), as they can all contract the same diseases. Harvest in 4 months.
Pumpkin - They grow and grow and crawl over everything, so plant them in an area where they have room to spread. Plant the seeds 3-4" deep and harvest in 4-5 months.
Tomato plants - Get those tomato plants in now, as in this week! Plant them deep in the soil. One nifty trick is to plant them close to marigolds, which will keep the aphids away.
