Wax bush beans are a warm-season vegetable. This tender annual is sensitive to cold temperatures and periods of frost. The bushes reach 1 to 3 feet tall and spread 1 to 2 feet wide. Bush beans stay upright without requiring support. White blossoms appear in the last half of summer followed by yellow bean pods.
Remove grass, weeds and rocks in a planting site with full sunlight. Loosen the soil with a shovel and add 2 to 4 inches of peat moss to improve the drainage. Work the soil until the texture is even and fluffy.
Use the side of a garden hoe and create a trench 1 inch deep once the soil temperature is above 60 degrees F in the spring. Plant your wax bush bean seeds 2 inches apart in the trench. Cover the beans with 1 inch of soil. Plant your other wax bush bean seeds in rows 18 to 36 inches apart. Sprinkle the rows with water until the soil is damp.
Water the soil around the base of the bean plants early in the morning. Give the wax bush beans at least 1 inch of water per week. Do not let the soil dry out while the bean plants are flowering and producing bean pods. Avoid getting the leaves wet since this encourages plant disease.
Spread 1 to 2 inches of peat moss around the base of the wax bush bean plants after the second set of leaves have formed. Mulching around the plants reduces weed growth and conserves soil moisture.
Examine the stems and leaves for beetles. Check the undersides for clusters of eggs. Remove any beetles and eggs from the leaves. Drop the insects into a jar of soapy water to drown them.
Pick the bean pods while they are firm, crisp and before the seeds are very large. Wait until the dew is dried off the plants before picking. Do not damage the stems and branches while picking. Wax bush beans continue to produce flowers and beans if the pods are picked before the seeds mature all the way.
