How to Water a Bean Plant

Overview

Don't buy beans when you can grow your own row of bean bushes or vines in your backyard vegetable plot. Varieties such as runner beans, soybeans and snap beans can all be harvested from the home garden. For optimal bean plant development and bean pod production, bean plants require just the right amount of water. Too much or too little can cause various diseases or stunted growth.

Step 1

Water a buried bean seed twice a day or as needed to keep the soil perpetually moist. Continue for 10 to 14 days until the seed germinates into a bean seedling, after which watering frequency drops.

Step 2

Water the bean plant once a day by applying water to the bean's base; watering its foliage increases the risk of foliar fungal diseases such as leaf blight. Water in the early morning with approximately 1/7 inch of water, according to Purdue University Extension.

Step 3

Pile mulch around the bean plant to conserve soil moisture and keep the bean plant hydrated longer. A 2-inch layer of organic material, such as aged compost, shredded leaves or straw is sufficient, according to Ohio State University Extension.

Step 4

Water the bean plant again immediately after fertilization. Evenly sprinkle 1/2 cup of 33-0-0 fertilizer alongside every 25 feet of bean plants once the bean plant grows flowers. This gives the plants the nutrient boost they need for proper fruit development. Watering helps carry the nutrients into the soil for immediate use.

Things You'll Need

  • Mulch
