Edamame plant growing (Water the edamame after it flowers) – Edamame bean plant growing guide

How to grow edamame bean plant in the ground cultivation. Last time, I did things like thinning the edamame, mounding soil (hilling for edamame), and setting up an insect netting (pest protection for edamame). This time, it’s about watering the edamame as harvest time gets closer. (Managing the growth of edamame is on our agenda for today.)

Watering the edamame (edamame plant care)

Thinning the edamame, mounding soil (hilling for edamame), and setting up the net were done in late April.

More than 40 days have passed since thinning and hilling and setting up insect netting for edamame. The plants have grown taller, and edamame pods have started to form.

Edamame bean plant needs watering from after it starts flowering until harvest time. If edamame plant doesn’t get enough water and dries out, the beans inside (edamame pods) won’t grow big. So, make sure to water them regularly.

Edamame needs water after it flowers

When to water the edamame bean plant? I think the best time to water edamame is in the morning. This is because vegetables and plants do photosynthesis most actively in the morning. So, if you water them at that time, the edamame can absorb water more efficiently.

I think the way to water edamame is different for each person, but in my case, I water around the edamame bed. I feel like it’s better to water directly at the base of the edamame plants, but if I do that, the mounded soil will wash away. So, I water around the bed instead.

Do not water at the base of the edamame plants

If the soil at the base of the edamame washes away, the roots that grow from the stem (adventitious roots) will be exposed. I don’t want that, so I started watering below the edamame bed.

Since the edamame plant has grown this much, I think the roots have spread outside the edamame bed, so watering between the beds should be enough.

Give about 2 watering canfuls of water to each spot. A typical watering can for home gardens holds 6 liters (6 qt) when full, so that’s 12 liters (12 qt) for each spot.

This is how to water edamame bean plant. At this time of year, check the weather forecast. If sunny weather continues, the soil will dry out, so water regularly.

For edamame grown outdoors, you can expect a good harvest by the harvest time even if you rely on the weather. So, if watering is too much trouble or you don’t have time, it’s okay to skip it.
