How to Grow Okra
Long popular in the Southern United States, okra is making inroads in vegetable gardens across the country. The pod-like fruit is a wonderful addition to soups and stews.
Corn does not have a very deep root system, so be sure to plant in a spot that's in full sun yet sheltered from the wind. A good blast of wind can flatten a corn plant.
Prior to sowing the seed, it's best to amend the soil. Begin by using a garden tiller to break up the planting area. If the soil is hard, make several passes over it until it's sufficiently loosened (Image 1). Next, add the first round of composted topsoil and manure, then spread it with a rake until it's evenly distributed (Image 2).
Corn requires lots of nitrogen, so this need should be addressed with fertilizer prior to planting. First, check the soil temperature, then add nitrogen-rich fertilizer for ideal corn-growing conditions. Select a mixed fertilizer with a 10-10-10 formula – that is, 10 percent nitrogen, 10 percent phosphorus and 10 percent potassium; and add at a rate of 4 cups per 100 feet of planting row. (Image 1) Use a light garden tiller (or a garden fork) to work the fertilizer into the soil about 3 to 4 inches deep (Image 2).
Sow sweet corn seed in full sun when the soil warms to between 60 and 95 degrees Fahrenheit. Sweet corn does not germinate well in cold soil and in low temperature will die. Sweet corn seeds can appear shrunken and shriveled; before they can germinate, they must slowly plump up with water. To help them along, soak dry seeds in water at room temperature overnight before planting (Image 1).
More Planting Tips: In the warmer climates, direct-sow seeds in mid-May: The cobs should be ready for picking in late August or September. In cooler climates, sow the seeds under glass in mid-April to early May, then plant out in late May to early June.
Any seedling transplants should be started in peat pots three weeks before you are ready to set them out (Image 2). To start seedlings indoors, sow 2 seeds — each about an inch deep — in 3" peat pots. To help them germinate, keep the room temperature at a gentle heat of 55 to 59 degrees Fahrenheit. Once they've germinated, use a cool-white fluorescent grow light to aid their growth: place the light about 2" above the plants. Leave the light on 12-14 hours a day and be sure to raise it as the plants grow.
Before transferring seedlings outdoors, harden them off by gradually acclimating them to outside conditions. To do this, place the seedlings outside during the day when temperatures are above 40 degrees Fahrenheit; do not set the plants in direct sun or high wind. Set them wherever there's shade. Move them out a bit more each day for greater exposure to the sun. Each night, bring the plants indoors. Provided they are at least 2" tall, after three to five days of hardening off, they'll be ready to transplant outside.
Mark off the rows by staking the bed to create rows. First, place stakes the length of the bed and then stretch string along the ground to mark the planting line. Be sure to leave 20 to 36 inches between the rows for cultivation and plant at least four rows for the best pollination. Many short rows will provide better pollination than a few long ones.
Use the edge of a hoe to draw a shallow furrow, 1" to 2" deep, along one side of the string. You then remove the stakes and string and place ID markers at the end of the furrows. Drop the corn seeds into the planting furrows, spacing the seed drops 4" to 5" apart. Plant two or three seeds to ensure good germination. Cover the corn seed by raking 1-1/2" of soil over them using the soil from the edges of the furrow.
Once the seeds are planted, water the block rows well. Good soil moisture is especially critical for the germination of extra sweet corn, as it must absorb more water than any other types for germination to occur.
This crop will require at least an inch of water from rainfall or irrigation per week for normal growth. Now as the plants grow, there is some special care that needs to be given to the seedling. Mound the soil around the stems to support then against wind in exposed areas.
When plants are about 6" tall, thin the seedlings. Crowded corn will bear fewer, smaller, and poorly filled ears. Using scissors, thin the plants to 8" to 10" apart if all seeds in a spot germinate and grow. Be sure to thin out the poorer seedlings, saving the best plant from each spot. This is also a good time to side dress the plants with 10-10-10 fertilizer, which will help encourage the young seedlings to grow. After you finish side dressing you lightly water in the fertilizer.
Tip: As plants grow and weather becomes warmer, increase watering. When roots appear at the base of the stem, cover them with soil or mulch with old compost.
Sweet corn should be ready for harvest about 80 to 95 days after planting depending on the variety. Each cornstalk should produce at least one large ear. Under good growing conditions many varieties will produce a smaller second ear. Your first ears of corn are ready to pick 20 to 24 days after the silks have grown about 1 to 2 inches longer than the tip of the ear. Harvest sweet corn when the ears are full and blunt at the tip. The husks should be tightly folded and green. When the tassels die and the cob stands out from the stem at about 30 degrees, it's harvest time.
To test your ears, you use your thumb nail to poke an end kernel. It should squirt forth milky white sap. If the liquid is clear and watery, the corn still needs a few more days on the stalk.
To harvest an ear, grasp it firmly, bend it down and pull toward the ground with a twisting motion. Try to break the ear shank without breaking the main stalk or tearing the entire shank from the stalk.
To maintain the sweetness and freshness of the corn, cobs should be immersed in ice cold water as soon as possible after picking, and left in the water until eaten. The ears should be eaten, processed or refrigerated as soon as possible.
The best time to pick corn is just before eating. But if you have to store it, get it into the refrigerator, unhusked and wrapped in damp towels as soon as possible. Try to use the corn within 1 to 2 days and do not husk until just prior to cooking.
The best way to shuck corn is to pull the husks down the ear and snap off the stem at the base. Under cold running water, rub the ear in a circular motion to remove the silk or use a stiff vegetable brush. Discarded husks can be shredded, then composted and placed back into garden soil.
Freezing is the best method for preserving the quality of sweet corn. It can be stored in cool conditions for about 5 days, but remember: the best corn is simply the freshest corn.
