I'm working on the back garden being very productive (it generally has a small patch of peas, couple of broad bean plants, and a couple of tomato plants). Simple enough things - DD is eating a lot of spring onions so I have planted a good few, 2 window boxes of salad leaves and 1 of spinach (for baby leaves) that should be "cut and come again" if I just pull a few leaves at a time, I have more tomato plants than usual (but can't get the type for the basket), and some courgettes, as well as my peas, broad beans and hopefully some French and borlotti beans. I have a small bed (about 3'x4'), 1 hanging basket, and some pots/window boxes.
I'd love to improve my rainwater catchment, especially now while the spring weather is still sending rain. But there isn't an easy solution so I just have 1 small barrel - that has been useful in the past when water mains were severely damaged by winter freezes in 2010 for toilet use etc, and as a reservoir for extra water when they were repairing it for weeks so no water in daytime and reduced pressure at night (so I would use buckets from it to flush downstairs toilet by day, and refill it by night using the same bucket from the tap).
Some kind of shade would be good out the back, we have a sail but it's too small and very difficult to get up. So I need to see what's feasible.
I still have some suncream from last year, but will organise myself when I do a big Boots order soon - I need deep conditioner for my hair and shampoo, shower gel for the family, and antibac soap, so may as well try a "click and collect" order to the local small branch which never has these things.
And I want to go through my general supplies - I am trying to use up older items at the moment, baking supplies, tinned goods, spice mixes etc, as well as everyday things. But I need to have a think about what we have been using more of as our habits changed while at home, and what we would need over summer and restocking for winter (both general and potentially virus re-emerging and causing another lockdown).
