How to Grow Bush Beans - The Complete Guide

Bush beans are a rewarding vegetable to grow at home and an excellent addition to any garden. Below we share the basics of growing bush beans in a home garden, as well as common mistakes and considerations.

When to Plant Bush Beans

Bush beans are not a frost tolerant vegetable. This means the best time to plant them is mid to late spring, once there is no longer a chance of frost in your area.

If you live in the U.S., check out the Farmer’s Almanac or the USDA’s Plant Hardiness Zones for more help regarding frost and the best dates for planting in your area.

How to Plant Bush Beans

Plant your bush bean seeds directly in the soil of your garden or container at a depth of 0.5 inches (1 centimetre). Seeds can be planted outside or you can germinate them indoors and transplant them later. Typically, bush bean seeds take about 1 - 2 weeks to fully germinate.

If transplanting, the best time to move bush bean plants outside is when they reach 3 - 4 inches (7 - 10 centimetres) tall or have at least 3 - 4 true leaves.

When planting bush beans in the garden, it’s best to space them 1 - 2 feet (30 - 60 centimetres) away from the nearest plant.

How to Grow Bush Beans in Pots

The key to caring for bush beans in containers is well draining soil and a pot big enough for their root system. Aim for a pot that is roughly 288 cubic inches (4,719 cubic centimetres) in size. Any old flower pots you have lying around should do the trick.

How Long do Bush Beans Take to Grow

On average, it takes about 40 - 50 days for planted bush bean seeds to develop into a fully mature plant.

How Big do Bush Beans Get

Typically, bush bean plants reach about 2 - 3 feet (or 75 centimetres) in height. Though this can fluctuate depending on the variety.

How Much Sunlight do Bush Beans Need

Bush beans need at least 6 hours of direct sunlight every day in order to thrive. Be careful to place your plants in an area that receives adequate sunlight. Otherwise, they may not mature properly.

How Much Water do Bush Beans Need

Bush beans like well draining soil that is kept consistently moist, but not wet or soggy. The amount of water it takes to achieve this effect will differ depending on the type of soil available to you.

Be sure to water your bush beans on a consistent, steady schedule. This will ensure the plant yields a healthy, uniform crop.

If growing your bush beans in pots, they will need to be watered more frequently than bush beans planted directly in the garden.

You will know your bush beans are in need of more water when their leaves wilt, yellow, and/or the plant begins to droop. But be careful, this can also happen if the plant receives too much water. This is a difficult balance for most novice gardeners. But the more time you spend with your bush beans, the better you’ll be able to gauge how thirsty they are.

How to Harvest Bush Beans

Leaving a short bit of stem attached, cut the bean from the plant with a sharp knife or scissors. Be careful to avoid pulling them by hand, as this can cause vines to break.
