Herbs and Vegetables, You Can Grow on Your Veranda or Patio
If you’d like to maintain a garden, but don’t have lots of space, you can always turn to container gardening. Here are plants that will grow well in containers.
As far as how much soil you need per plant, a 4-litre pot is a good starting place and keep in mind that a plant can only grow as large as its container. Therefore, you will get smaller a plant and thus fewer peppers from a plant grown in a 4 litre, compared to a 20-litre pot.
Additionally, the larger container will require less frequent watering. So, if you want to grow more food, use bigger pots.
Here is a good way to make your own potting mix.
I like taking a bag of cheap potting mix. Why cheap? Because it usually contains no fertiliser. I then add some worm castings (fertiliser), some vermiculite and some coconut coir (because they hold your moisture) coir (this will help feed the worms).
Employ the technique of square foot gardening (which is usually used in raised beds) when it comes to smaller plants such as carrots, spinach, and lettuce. The wider the diameter of your container, the more individual plants you can fit without overcrowding.
