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.

Newspaper Biodegradable Pots - Free and easy!

First get some newspaper and fold in half, rolling along a jar and folding the bottom so it forms a pot. Repeat. Many times.

Then put in a tub, fill with soil and place seeds in. Water with compost tea until you have about 1cm of water remaining at the bottom to ensure seeds wont dry out. You may need to water regularly until the roots reach the water.

Once seedlings are big enough, plant pot and all! you can unfold or rip the bottom and top, as leaving newspaper above the surface can wick out water- drying the plant out. If you want you CAN remove and compost the paper but this is great for plants that hate translating from root shock so that's kind of the purpose to leave it there! So easy and quick and free!
