Time (almost) To Plant Warm Season Crops

Okiedawn OK Zone 7
16 years ago

For those of us who use the OSU-recommended planting dates, the time to plant cool season vegetables is ending, and the time to plant warm-season crops is almost here.

As always, the earlier date given is for southernmost Oklahoma, the later date given is for northernmost Oklahoma, and everyone who lives in between the two can choose their planting date accordingly.

Sweet Corn (seed) March 25 - April 30

Green Beans (seed) April 10 - April 30

Cucumber (seed) April 10 - April 30 or later

Eggplant (plant) April 10 - April 30

Okra (seed) April 10 - April 30 or later

Pepper (plant) April 10 - April 30 or later (only after temps are consistently above 55 degrees)

Pumpkin (seed) April 10 - April 30 or later

Summer Squash (seed) April 10 - April 30 or later

Tomato (plant) April 10 - April 30

Lima Beans (seed) April 15 - April 30

Cantaloupe* (seed or plant) May 1 - 20

Watermelon (seed) May 1 - May 20

Southern Pea** (seed) May 1 - June 10

Sweet Potato (plant) May 1 - June 10

Winter Squash May 15 - June 15

*Cantaloupe. The netted melon we in the USA refer to as "cantaloupe" is actually a "muskmelon", but I used the name "cantaloupe" here since that is how they are known. The planting date given is good for cantaloupe and muskmelon, and all the other melons as well, except watermelon.

**Southern pea refers to the group of heat-loving peas. This includes black-eyed peas, field peas, crowder peas and cream peas, but NOT the cool-season peas like snow peas and edible podded peas.

For plants that must be started indoors and transplanted out as plants, you COULD direct-seed but should not expect a crop until fall. These plants have to bloom while temperatures are still somewhat cool, or the blossoms won't set fruit. So, if you direct-seed them, they bloom later when it is "too hot" and, thus, won't set much (if any) fruit until daytime high temperatures drop in the fall.

For plants that are generally direct-seeded, you often can sow them indoors and transplant them outside into the ground. This includes sweet corn, beans, southern peas, melons, pumpkins and okra. Why would you want to do this?

There are several reasons, including to get a harvest 3 to 4 weeks earlier and to get a full row or block or crops with no "empty" places where seeds failed to sprout. They key to success is that the plants DO NOT generally like to be transplanted, so if starting them indoors, plant them in a plantable pot (peat pellet, peat pot, newspaper pot, paper (not plastic) cup, etc.

I don't follow these dates precisely. For example, if the soil is still below 55 degrees, I won't plant until it gets to 55 degrees for the top tier of plants (green beans through lima beans). If the soil is still below 65 to 70 degrees, I'll wait for it to warm up to that temperature before planting the second tier of crops (cantaloupe through winter squash).

And, just because a planting date is recommended, you still have to be sure you're pretty confident that the last frost has come and gone before you plant. These are all tender plants and they will die if subjected to frost or freezing temperatures. Remember that frost can form at air temperatures as high as 38 degrees if the night sky is cloudless and there is no wind.

Happy Planting!
