I had an allotment a few years ago - I got it when DD was 1, and had it for 6 years. I really loved it, but couldn't give it the time I needed to (it was a 20 min drive and further 15 min walk, with all tools as no sheds allowed, for each trip, and as I was still working FT and then DH was away 50% of the time, the last 2 years were really hard).
I remember the first year was pretty hard getting started, but DH was around and did a lot of the initial heavy digging with me. We planted a lot of potatoes and onions (we did that every year, but 1st 2 years were our best), and I got a load of brassica plants - something like 15 each of cabbage, cauliflower and broccoli - from either Suttons or Thompsons and put them into another bed. We dug a bed, planted it up, then dug the next section....and managed to get half the plot cleared that spring!!
Covering patches with weed suppressant membrane or cardboard worked well on beds we wanted to put things like brassicas and courgettes/pumpkins/squashes. To plant the plants through holes and keep weeds down. We planted one bed completely in fruit bushes (raspberries, blackcurrants, redcurrants, gooseberries and rhubarb) - which was great!!! And we grew plenty of broad beans, peas and a few wigwams of French beans and borlotti beans too. Lettuces and spring onions were tried, and carrots, but none worked great (slugs and carrot fly). Parsnips were decent though, and Brussels sprouts when I grew those from seed (after the 1st year).
The hard parts were lugging the tools, lugging water from the tap in watering cans (about 7 mins one way across the plots! and not smooth enough to use a wheelbarrow) and trying to get rid of the scutch grass. But we got some great results from it and it's what encouraged me to get more intensive with my planting in the garden. (It was also great to disappear up there for 3-4 hours and spend time mindlessly weeding and digging, NOT worrying about work or house things, just letting them flit through my mind and solutions often flitted through as well to problems
).
Anyway, I am happy to see life getting going in the back garden again.
