Wooo, I love it that your beans in the farm are bearing fruits, please help me @johnny023,

At what time of the year is suitable for planting beans.?

What method is usable to make them grow and bear fruits?

I lost totally on the Beans I planted in my garden. I planted them in the month of May this year.

They all germinated quite alright.
They had beautiful leaves, growing up and crawling everywhere, even beyond my boundaries.

But no singular boarding of fruits were seen,

I mean they never showed any fruiting at all, I didn't harvest even one piece....

I became utterly surprised as to what might have caused such fruitlessness.
Some few days ago, I went and uprooted them all, im in shock.

What advice and tutorial can you give me now on what happened to them. Please reply i'm waiting.

Because there was enough rainfall, sunlight and they were planted on a lomey good soil,

I even applied fertilizer on them yet no harvest at all from them.
