Soul-Rama:

Some things you can do to save space include growing plants in stackable towers rather than flat rows. Not everything can grow this way, but growing herbs or even strawberries or some kinds of tomatoes in them can save a lot of space. Bonus points if you can get some vertical vining plants like beans or tomatoes to grow up the sides of them to maximize the space used.

Hanging planters can also be used for things like tomatoes, herbs, some berries, etc. The people who grew up watching TV in the 2000s may remember ads for the topsy-turvy tomato planter. I can’t vouch for the effectiveness of them, but it may be good inspiration for creative DIY hanging planters.

Many people don’t seem to know this (to be fair, it’s not very intuitive), but small melons and gourds can be grown vertically on a trellis. You will need pantyhose or something else that can act like a sling for when the fruit gets large enough, and you’ll also want to make sure the trellis is very sturdy. Here is an example of a watermelon growing on a trellis, with squash growing in the background:

Other good options that require a bit more DIY are hydroponics towers and walls. It’s basically just a series of pipes with holes for plants to grow out of. The only downside is they will require very regular fertilization and supplementation with other micronutrients that are essential for plant growth, because the plants are typically grown in either a non-nutritious medium like coconut coir or nothing at all.

Planter walls are the next step down, basically just building shelves with pots in them to fill with soil. Put these on a wall that gets good morning sun and some afternoon sunlight for best results. These and hydroponics both also have the advantage of being able to hook up to your gutters so that rainwater will go towards watering your plants rather than just being wasted.

If you want to get really fancy, aquaponics is the next step up. With aquaponics, you create a system that circulates water between plants and a tank full of fish. The fish waste provides fertilizer for the plants, and the plants help filter out the waste so the water stays cleaner. I’ve heard they’re a bit tricky to establish, but once you find the right balance, all you’ll need to do is feed the fish. This has the added bonus of providing a source of fish for people who can’t eat things like nuts and legumes but need protein. Here is a link to an article explaining what aquaponics is, how it works, and how it differs from hydroponics.

Most of us can’t do it ever even if we use all our space perfectly. Some of us can do it after years of building those skills, and we might still have bad years. And in the end, what does it get us? Self-reliance is a right-wing preppers dream but it isn’t what we should be aiming for.

If we’re thinking about collective survival and we’re looking at food as part of that survival, there’s two things that work:

Start a community garden. Bring together the resources, time and skills by getting together in a big group. 

Or learn to grow a few crops really well and share them with all your friends. 

If you have a lot of nice soil and can do physically exhausting work? Potatoes, pumpkins, zucchini.

If you have a green house? SOOOO many tomatoes. Fruits that require warmth. etc.

Are you a gardening nerd with time and an interest in learning complicated plants? Take on the challenges like broccoli, cauliflower and depending on your needs, location and options, maybe cannabis? Or build a permaculture garden if that’s your thing.

If you have a balcony or window sill or prefer to do light work in high mobile planters due to limited space or mobility? Leafy greens, herbs, radishes, carrots, maybe a small tomato plant.

Peppers are perennials and we talked about bucket planting for those so you can bring them inside if your winters get cold to overwinter and bring them back out in the spring.

In learning how to garden and grow produce it helps to start small and scale up year to year. Try new varieties and planters and spots in the garden, find ways to allow things to volunteer in the spring (leaving peppers, basil and other plants to cast seeds directly). You’ll learn and grow so much, even if much of it isn’t edible.

Remember to grow flowers too - not just because they are pretty but they will attract pollinators who will help your produce grow too! Sunflowers grow great in the US so don’t sleep on those babes.
