Gardening - What's Your Greatest Expense in the Garden?

Last year i bought these, like, just tin raised beds. Thet actually weren't that expensive, but they were really brilliant. And cata. I don't realize how they can of keep the heat in a little bit and, but also just makes it so much easier to get to stuff. Was ashling b who has a lovely garden, who has one, and she just grows a jasmine, and i think she's got a whisteria up there as well. And m ye, it's slowly getting there, but it's of early stages with that. How big is your garden? Is it something, you've got a fine vertical space to grow more?
