Your question: What pollinates a corn plant?

Does corn need to be pollinated?

Unfortunately for the home gardener, manual pollination of corn is almost a necessity. Even if your plot of corn is fairly large, learning how to hand pollinate corn can increase your yield and help prevent those sterile stalks that are often found along the edges of your planting.

Is corn self pollinated or cross pollinated?

All types of corn readily cross-pollinate. Sweet corn must be isolated from field corn, popcorn and ornamental Indian corn either by location or flowering dates, or the ears harvested will have kernels of different types.

When should you Detassel corn?

Check your corn plants for developing tassels twice each day when they reach about 2/3 of their full mature height. This is when the reproductive process begins. Once all the tassel’s lateral spikes emerge completely from the top of the leaf sheath, a corn plant is only a day or two away from scattering its pollen.

How long does corn pollination last?

This timing is given a colloquial term – nick. Pollen shed and silk receptivity to that pollen last for at least six days, so some leeway is built into corn plant development to help ensure that pollen is shed when silks are available to catch the pollen.

How many ears does a corn plant produce?

Most sweet corn varieties will have one to two ears per plant because they are mature rapidly and are generally short statured plants. Early maturing sweet corn will have one ear while those that mature later have two harvestable ears.

What happens if you cross pollinate corn?

If you plant different varieties of sweet corn close together, you risk cross-pollination as sweet corn is pollinated by wind. Cross-pollination can lead to starchy and inedible corn, and you no longer have a clear harvest or maturity date as varietal recommendations no longer apply.

What is the lifespan of corn?

An important food crop for humans and farm animals, corn (Zea mays) grows quickly when soil and air temperatures remain warm and moisture plentiful. Avoidance of freezing temperatures and drought allows a corn plant’s life span to range from 90 to 200 days, depending on the individual variety and extent of warmth.

What happens if corn doesn’t get pollinated?

If there is insufficient pollination you will get spotty corn. In a large field of corn, the agitation created by the wind will sufficiently spread the pollen (corn pollen can travel up to 1/2 mile). In your backyard, the pollen may blow into the neighbor’s yard completely bypassing the silks.

Does rain affect corn pollination?

Stress conditions (such as hail damage and drought) have the greatest impact on yield potential during the reproductive stage. This year’s excessive rainfall has resulted in highly variable conditions within corn fields with regard to saturated soils and ponding, which may impact uniformity of pollination.
