Make the most of your small garden space.

I have a space 5x7 with half being full shade. This is how i make do...

GO VERTICLE -
i plant pots on shelves, it quadruples the plants. Also planting trellises to keep vining plants vertical. And strawberries in recycled stacked 2 Lt bottles etc.

DOUBLE PURPOSE -
Hamburg parsely (root and leaves), entirely edible plants, like nasturtium or radishes (flowers, green seeds, leaves), strawberry spinach (berries and leaves),

BE CHOOSEY -
only plant the plants you actually love to eat

GO DWARF -
Plant mini varieties or heavily prune.

POTS -
put post on concrete that is otherwise useless.

PLANT SMART -
I have half of my patch in pretty much full shade, so i plant greens here to prevent them bolting early and keep them tender. Also broad beans and peas and other plants that aren't so warmth and sun thirsty like some alliums just for the greens. I also plant stuff under my fruit trees because I have no choice. I don't have problems with them competing too much but it's best to plant deeper rooting plants with trees i think.

HIGH YIELD VARIETIES -
plant high yielding plants like mouse melon and green tigerella to the most bang for your buck so to speak.

PACK IT IN -
but not too much so that things get starved for sun. It keeps weeds down and if you have good soil it actually works out well! Try not to monoculture too much and have patches about the place so pests don't find all your patches and you can have some untouched plants.
