If you are short of garden space or water then hydroponics is a fun way to grow plants. Here is some information about ways that I have grown herbs and vegetables without using soil.
Mature silverbeet plants growing in expanded clay balls in waist high benches. In the background are asparagus plants growing in a bathtub which is resting on the ground. |
Young beetroot plants growing in expanded clay balls. As they grow, the larger beetroot are harvested early to leave room for the rest of the beetroot plants to fill out. |
Tomato plants trained on a twine trellis with beetroot plants filling in the space around the roots. |
Seven year old asparagus plants growing in a 20 litre container filled with perlite. |
Eggplant grows rapidly in self-watering plant pots filled with shredded coconut fibre. |
