Do you have a small garden and do you want to enjoy it to the fullest? Then try to turn it into an 'edible' garden! Plant as many edible plants as possible that produce vegetables or fruit for years in a row so that you do not have to keep buying new plants or re-sowing them.

What would we definitely put in it? A fruit tree. You can grow them very well against a fence. You make it into an espalier by stretching iron wire against the fence, about 50cm above each other. You tie the branches to that. An additional advantage is that more fruit grows on horizontal branches than on branches that grow vertically! Maybe you can even plant an almond tree. It blooms beautifully early in the year. There are self-pollinators, but you get a greater yield through cross-pollination by peach and nectarine trees. Tip: take a look at what the neighbors have, who knows, you might be able to create a win-win situation together. 

Permaculture recommendations that are doing well in the Netherlands: a Mulberry tree, the Fig, Rhubarb (red stems are sweeter than the greens), Jerusalem artichoke: plant the tuber in March/April. This tuber grows into approximately a 1m high plant. You can eat the tubers. Save some of the tubers to plant again in the spring.
