Sweet corn needs ample water from germination to harvest, but the most critical period for water is about 2 weeks before silks form. Aim for 1 inch of water per week, and supplement natural rainfall with irrigation as needed.
How often does corn need to be watered?
Corn needs about 1 inch of water a week, particularly when the stalks begin to tassel. Water stress during pollination will result in ears with lots of missing kernels, so don’t skip watering your corn patch. Apply water at the soil surface by using a soaker hose or drip irrigation.
Does corn use a lot of water?
High yielding corn requires approximately 22 to 30 inches of water per year depending on planting date, planting density, maturity group, location, and weather conditions. Corn requires the most water during the early reproductive growth stages (Table 1), which are also the most sensitive stages to water stress.
Does corn need to be watered daily?
As a member of the grass family, corn is a high-demand moisture crop that needs an inch of water each week. The goal is to keep the soil consistently near the 75% moisture content. With very sandy soil, a little more may be necessary. One inch of water should wet the soil to a depth of at least 5 inches.
When should I stop watering my corn?
Like field corn, irrigation for sweet corn should terminate at maturity. For sweet corn, this could be anywhere from 60 to 100 days.
Does corn like wet soil?
Soil Requirements
Besides warm sunny weather, corn requires rich, moist soil. In addition, before planting seeds, make sure soil temperature ranges between 60 and 65 degrees Fahrenheit. Otherwise, corn seeds will not germinate properly.
What happens if you over water corn?
Excessive soil moisture or standing water causes a lack of nutrient uptake in the plant. This can lead to pollination failure and severely reduce yield potential. In general the corn can tolerate no more than two to four days of standing water during this critical growth stage before yield loss become severe.
Why is my corn dying?
If you have withering corn plants, the most likely cause is environmental. Corn plant problems such as wilting may be the result of temperature fluxes and irrigation, although there are some diseases that afflict corn plants that may result in wilted corn plants, too.
What crops are water intensive?
Some of the most popular crops today are highly water-intensive.
Water-Intensive Crops
- Rice.
- Soybeans.
- Wheat.
- Sugarcane.
- Cotton.
- Alfalfa.
- Pasture.
What does an over watered corn plant look like?
Droopy or yellowing leaves are signs of overwatering. Some yellowing leaves are not an issue and this, along with leaf loss, often happens when the plant is moved to a new location. Corn plants prefer to be slightly pot-bound and shouldn’t need to be repotted more than once every three years.
Does corn need a lot of sun?
Corn grows best in loamy, well-drained soil under full sun — six to eight hours of unfiltered sunlight daily. Prepare the garden bed by turning a generous amount of compost and/or aged manure into the top 8 to 10 inches of soil.
Why is my corn plant turning yellow?
Yellowing corn leaves are most probably an indicator that the crop is deficient in some nutrient, usually nitrogen. Corn is a grass and grass thrives on nitrogen. The plant moves nitrogen up the stalk so a nitrogen deficiency manifests itself as corn leaves turning yellow at the base of the plant.
What causes corn not to fill out?
The list of possible causes includes severe silk clipping by insects (corn rootworm or Japanese beetles) during the final stages of pollination, delayed silk emergence or deterioration of exposed silks due to excessive heat or drought conditions, silk emergence failure due to silkballing near the tip of ear, and lack
How do you fertilize sweet corn?
Apply three to four pounds of 10-10-10 fertilizer per 100 square feet. Fertilizer should be broadcast evenly and worked into the top two to three inches of soil prior to seeding. When corn is 12 inches tall it is a good idea to apply a sidedressing of fertilizer. This is especially important on light sandy soils.
Can you over irrigate corn?
Of course, excessive irrigation/rainfall and soil saturation will stunt plant growth, reduce corn yield potential and promote nitrogen loss as well.
How do you grow sweet corn successfully?
Plant seeds one inch deep, and eight to 12 inches apart, with rows 30 to 36 inches apart. Plant in blocks of at least four rows rather than a long single row for proper pollination. Small, lightweight Shrunken (sh) kernels demand the most care at planting. Do not plant them deeper than three-fourths to one inch.
What’s the best fertilizer for corn?

What happens if you don’t thin corn?
For those of you that don’t know, thinning plants means selectively removing seedlings. Corn plants will take a bunch of water and nutrients from the soil during their life span. If the plants are growing too close together, problems may arise. The root systems will end up growing into each other.
Why are my corn stalks so skinny?
Corn plants require lots of nitrogen for development. When the soil is nitrogen deficient, these plants develop stunted growth. Adding nitrogen fertilizers to replenish soil nutrients helps corn that is shorter than normal.
Should I water my garden every day?
Plants do best when watered about three times a week, factoring in the rain. If the plants are seedlings, water twice a day until established. But don’t just water without thinking.
How do you tell if a plant is overwatered or Underwatered?
When plants have too little water, leaves turn brown and wilt. This also occurs when plants have too much water. The biggest difference between the two is that too little water will result in your plant’s leaves feeling dry and crispy to the touch while too much water results in soft and limp leaves.
