So, as my husband is one of the 1.5 million who have to remain housebound for the next 12 weeks or so, I decided that I should do the same. He has spent the last 3 years fighting the cancer which will eventually kill him. At present the immunotherapy that he is on is keeping the cancer from spreading. I would not want to go out, come into contact with the virus and take it home. So last weekend knowing he would be on the extremely vulnerable list, I closed up my plot, I hadn't put anything other than onions in and the fruit bushes will fend for themselves.
My view is that at the end of the day, these are only fruit and vegetables and that my allotment will still be there when all this is over. I'm growing what I can in pots in the garden and in the flower borders to keep me occupied. I still think I will go crazy only being able to go in my garden. But it has to be done.
Keep safe.
