    I always found runner beans to be a glut or famine crop, not a nice steady supply.
    But i guess that depends, if you have lots of people to feed it's a different matter.

        Pollen is more viable in the morning before the sun shines on it with Daylily's / Hemerocallis if I am crossing plants I have to use the pollen early in the morning as late afternoon the pollen is dead as such ...

          Makes sense, day lilies being a new flower every day.

            I spend each morning checking the back of the leaves for Blackfly, now looking at the stems. Not seen one Ladybird yet.

              My broad beans came close to nearly being destroyed by blackfly.

                Both early (april) sowing and may batch have now exceeded the sticks by 3 feet. Some beans in the top 4 feet of growth have been enjoyed but although heathy looking, they have ceased flowering due to the drought conditions. water butts empty and hosepipe ban imminent. If I share my bathwater with them, can anybody suggest means of kick starting , by pruning or feeding , so that they burst back into bloom? Surely there could be 8 weeks or so left in the bean season yet?

                If you're unable to keep watering then you should nip out the tops that are going well past the canes. The plants will then not have to try and support those tops of them.

                We have been able to keep watering our beans well, very heavy watering two or three times a week and not light watering more frequently, and they are doing OK but suffering from the heat. No significant rain in over four months with nothing forecast.

                I'm now picking 3lb-4lb per day - but we have a lot of plants. Some of the plants have given up on us :sad:

                  Mine are doing adequately now, picking a couple of lbs every few days. The plants are infested with blackfly so we have to wash the pods in soapy water to get rid of the sticky residue. I sprayed with neem oil a couple of days ago as a last resort.

                  The french beans on the other hand are pest free and providing us with much more.

                  The blackfly came back onto our runners, only some of them, and were very thick along the stems. I blasted them off with the hose four days ago and no sign of return this morning. Our French beans are also pest free.
