Simply build an A-frame support with the use of hazel poles, bamboo canes, or any thin woods. Using a netting for beans and peas is also a good option, especially if you plan to sow a large area of this vegetable. If the plant has grown over the support material, remove a part on top so it doesn’t become too heavy that may cause falling down and potentially damaged the beans.

3. Sow Seeds

Seeds can be bought at local garden shops or collected from leftovers. These should be buried in small pots or a raised bed with the right soil. Dig 2 inches deep and place a handful of seeds. Cover, add organic compost and pour a little water.

For the first few weeks, it is best that you place them somewhere in a sheltered position or a greenhouse. Once they grow for about 3 inches tall, you have to transplant them outside in full sun.

4. Water Regularly

Halo blight is a common bacterial disease causing brown spots on leaves. Believe it or not, this is developed from the seeds, mostly if not properly stored before harvest. To avoid this, soak the seeds in clean water before planting. You also have to thoroughly check each seed for any unusual appearance, such as color and shape, and only use the unblemished ones.
