Farming in small backyards vs growing gardens simply for ornamental reasons, which are now as outdated as owning a Prince Albert tea set that may almost never be used. Farming in cities and towns, known as urban agriculture, is the future and possibly the planet’s saving grace.
Where to start when considering farming in small backyards?
Combine edible and ornamental plants, insect and animals and micro-climates to create a sustainable ecosystem. The outcome should be a beautifully space to harvest food and also relax in.
Edible and ornamental plants are grown side by side as companions (see https://gardeningeden.net/2019/10/28/companion-planting/ ) to attract beneficial, and deter harmful pests. This really works! Your need for pest control will drop dramatically. Always plant successively so that you harvest today, next week and the week after from the same type of plant by sowing plant types 10 days apart.
Container gardens are a great consideration in regards to farming in small backyards: turn a little (possibly rented) outdoor space or window area into a small urban farm. This is an easy and cheap answer to most people.
Most importantly, the focus needs to be on polyculture (a word to describe growing many different plant types together) which will maximize yields. Combining climbing plants on a corn plant (which acts as a trellis) with pumpkins at their feet (to shade out weeds and help with water retention) is a great example. In order to do this successfully, you will need to feed your soil with compost. This is a great opportunity to stay within your own loop and use your own kitchen and garden waste to create soil food (see how to compost easily: https://gardeningeden.net/2019/11/06/diy-compost-easily)
Animal inclusion does not come easier than keeping quails (for smaller gardens) or chickens. Quails can be kept in a mobile upside-down chicken-wire “box” that allows them to move on bare earth but be protected from predators. They can thus be constantly moved to new spaces. Make sure the size of this wire-basket is big enough to allow their bodies to take up only 10% of the entire space and the rest is for moving around. Provide water and top-up food. Chickens and quails provide free pest control, fertilizer and eggs. It’s a win-win situation.
Ornamental plants are grown to attract pollinators or feed your bee hive if you have one. Group larger numbers of flower plants and herbs together because insects need spot these plashes from far away or they will fly to your neighbour’s.

Alternatively, keep your own bee hive. It’s never been this easy. Check out the mason jar method: https://gardeningeden.net/2019/11/25/is-mason-jar-beekeeping-method/
