Before I even started gardening seriously, I had google every website to figure out what to do with my limited, dirtless space. But I didn’t ever google “vegetable container gardening” until after this year’s experiments in urban container gardening and even then, I was overwhelmed by the detail involved. Vegetable gardening isn’t completely easy, but it shouldn’t be too hard either!
So i thought to myself, what would I have looked for if I were trying to start an urban container garden for vegetables? Especially if I were a beginner gardener, what would I need? So this post is a “what would I have done differently if I knew then what I know now.”
If I were to start all over again, I think I would have started with just two large containers. My favorite containers in the garden are these fiberglass half-whiskey barrel containers from Lowes. Each of them take 1 cubic feet of dirt, which is perfect because the Sta-Green Moisture Max container mix divides equally into both containers. I use this particular brand because it retains moisture really well, it’s light enough for me to haul around, and when it rains the crystals really work. The key here is that you purchase CONTAINER SOIL, no matter which brand you use. It’s a lot more expensive, but all of the other soil is too dense to put in a pot and you’ll end up giving your plants root rot.
Depending on where your containers will be kept, you can seal or unseal your planters, meaning you can either let them drain out of you can keep the holes in. This goes against everything you read, but I have a reason for it: if your container is on a sunny, covered balcony, protected from rain, and you don’t water it regularly, you want it to retain its moisture. By not having holes, you can insure that the water is taken up by your container mix and is released to your root system over time. And because the drainage is minimal, you won’t stain your balcony. This is, of course the reason why you need excellent container mix.
I would have purchased two tomato cages and planted the following in one planter:
- 1 patio tomato plant in the center.
- 4 Lettuce plants around the borders.
- 4 Small basil seedlings in between the lettuce. (Chives and oregano can be added too.)
- 4 Pole bean plants close the edge of the tomato cage. Beans should be planted directly from seed.
And in the other one planter (although the first is a lot more resilient):
- 1 cherry tomato plant in the center.
- 4 swiss chard plants around the borders.
- 4 beet plants in between the lettuce.
- 4 Pole bean plants close the edge of the tomato cage. Beans should be planted directly from seed.
All of the plants I would have tried to find seedlings for in April or seed started in the winter (Jan/Feb) except for the pole beans. I would not transfer anything outside until the middle of May, depending on the zone you’re in. If you start anything later than that, just make sure you pick healthy plants. The beans germinate quickly, so you can plant them when you transfer the rest of your plants. They just need to be reseeded every two weeks for continuous beans, meaning you need to remove the old plants and plant new ones once they stop flowering.
And that’s how I would start an urban vegetable container garden.
