Creeping buttercup in the spring, before the weather changed from cloudy and damp to warm and dry and I dug it all up.
It is difficult to say crop-wise because apart from the early potatoes, nothing has quite got to the point of producing yet, the squash have taken off in the heat and are now producing fruitlets, the French beans are flowering and will produce pods very soon, and the brassicas aren't up to size yet. So far the beans and squash look in the best shape and could be very productive, the prolonged hot dry weather has kept the slug damage right down so they have had the chance to establish and grow into mature plants. Fingers crossed that by the end of the month I will have a very productive allotment.
