Spring approaches, which means that it's time to start getting the garden ready... Trees to start mulching, last bits of pruning to be done, layouts to be finalised. Being on limited space is always a problem, but you make the best of what's available. While economies of scale would be nice to use - it can be easier to deal with large quantities of one or two crops - better self-sufficiency means getting a few of several.
There are plenty of places to get trees, herbs, and miscellaneous plants, you just have to make some judicious choices in regards to what you want and whether it makes sense (efficient use of the space, useful food or self-sufficiency product) to grow... And be prepared to lose the trees because they don't like the area, climate, etc... Also, if they get eaten by insects... My citrus trees are not going well, but perhaps by encouraging bird-life, I can get the birds to eat the insects that seem to plague the plants...
Which reminds me - there are a few seasonal crops I need to start up for spring... a couple of edibles, as well as cotton. Cotton is another of those crops that become easier to deal with when you're processing a lot of it - you start to build/accumulate/etc. things like cotton gins.
I'm wondering if I shouldn't get rid of all my non-cropping plants and just put in as much as I can. The problem with that is that getting rid of all your trees the ground no good. Apart from soil washing away, grass isn't good at getting moisture into the air. When you start cutting swathes of trees down, you make growing harder. Yes, I'd be putting in replacement trees, but they will take time. On the whole, I think I'll maintain my current pace - keeping most of the big, healthy trees, getting rid of scraggly or dying ones, but get rid of them as newly planted things are able to establish themselves...
