My beans are tall and lush but so far few blossom. Am I just getting in a hurry or are they lacking something. The plants are growing on nets and are 6' tall
They are lacking something in the soil. I've been picking here in the midlands UK for 3 weeks now. The make up of your soil will show via a simple soil test that here is too much of something and not enough of something else, thus promoting healthy foliage at the expense of flowers. The soil probably needs a much higher nitrogen content.
