It’s a good year for greenfly, blackfly and aphids. The real answer is to grow strong, healthy plants, and encourage as many natural predators as possible. We’ll look at why spraying works against you in the long run.
Whatever time of year you go to a restaurant, there seem to be French beans on the plate somewhere. To me they taste best fresh from the plant, full of natural sugars and minerals.
French beans like it warm and moist, the soil really has to be at full summer heat for them to flourish. Planting in late May or early June is best, as they grow away strongly and shrug off the slugs. Planting earlier than this so often ends in disappointment.
