I have recently taken on another allotment. I had one a couple of years ago but gave it up when we moved. I really started to miss it this summer as the feeling of eating your own grown veg is great. I took over our new one on 1st of July and have enjoyed lots of berries, lettuce, radish, spinach, pak choi, rhubarb and swiss chard. I have kept growing simple because of taking the plot over so late in the season plus we had a lot of holidays booked so I knew we would be pushed to keep on top of it. The fruit and vegetables are so easy to grow. The berries come back year after year with very little effort and the salad seeds were just poured straight into the ground.
If you have thought about taking on a plot then I would highly recommend it. Yes it takes time and effort but the rewards are great and it's very relaxing and therapeutic. Being a teacher is great as I can spend more time there over the holidays but if you have a partner and family that can support then this makes it much easier.
