We're in that same situation! I'd love to grow some of our own food, but we are currently renting and our townhome neighbors set their dogs free in the back. However, we do have hooks out on our front porch and I can hang planters from there.
Read on to learn how to make a hanging or vertical strawberry planter!
In order to make this planter, you will need a PVC pipe about 6" in diameter and as long as you'd like it. (Ours is about 2 feet long.) Drill 2" diameter holes in three rows down the planter. We got 9 holes in our planter. Create a cap for the planter using a PVC cap, just make sure to drill three drainage holes in it. If you will be hanging your planter, also use your drill to poke little holes at the top of the planter.
And voila, there is your vertical strawberry planter! A neighbor offered some of her strawberry plants, so I started with live plants (not seeds) and stuck them in the holes one layer at a time. After inserting a layer of strawberries, just fill the planter with soil until the soil reaches the bottom of the next layer of holes. Put your next group of strawberries in and repeat the process until your planter is full.
Strawberries need direct sunlight and a good amount of water, it seems. I usually give them 2 dinner glasses full of water each day.
I couldn't be happier with this planter! In all, it cost $5 and is a great option for the urban farmer. I also like that by having it hang, it's free of slugs and other bugs that would like to eat it!
