Plant a variety that developed resistant to some of the common pests and diseases in your area. You can get this variety of adzuki bean from your local growers. I recommend that you should not buy online unless you trust the website.

2. Plant your adzuki bean at the right time: the next step is to wait till the right time for planting adzuki bean comes. This is if you are not growing indoors. If you are living in colder climates, wait till all the dangers of last frost have passed. Plant your adzuki bean seeds when the soil temperatures pass 60°F.

However, if you are living in very warm areas, I recommend that you plant your adzuki bean seeds when the soil temperatures is below 90°F. Adzuki beans thrive well in USDA Zones 4 to 11. In general, the ideal temperatures for growing adzuki bean seeds is between the range of 69-90°F.

3. Choose a good garden spot: another important step that can’t be skipped is choosing a good garden spot. Do not start your garden in poor garden spot. Adzuki beans love a well-drained soil with average fertility and pH that is near neutral.

However, if you are starting seeds indoors, make sure you start your adzuki bean seeds in biodegradable pots (biodegradable pots are containers that can be composted. You can find them at Amazon). This is because adzuki beans are very intolerant to transplanting and they may die during transplanting. So, when you start seeds in these containers, while transplanting, you can transplant and bury the seedlings in the planting holes together with pots.

6. Take care of adzuki beans garden: as I explained earlier above, adzuki bean is easy to grow and maintain, you only need to plant them in the right place. However, you also need to water regularly and gently. Do not ever water or flood your adzuki garden. Just water enough to keep the surface of the ground moist. Flooding your garden can attract pests and diseases. The next thing is weeding. Weed the garden to reduce competition for water and nutrients.
