How to use recycled materials to irrigate your vegetable garden. I use old plant pots (the plastic pots that plants in which plants are sold).
I have used drip irrigation using pots with holes in them for the past two summers. This has worked well for us. In the winter I collect in all the pots which stack inside each other compactly until spring.
In spring, I space my plants closely around irrigation pot. Plant location and spacing is determined by the pot rather than rows or areas. I shallowly partly bury a pot them plant 3 or 4 plants around it. Then I place the next pot very near and repeat the planting process.
I partly bury the pot. Then I add some sand or soil to slow the flow. This means I can water in less time, leave more water per plant and use liquid nutrient instead of just water.
I make my own compost tea for the plants. Home made liquid fertilizer is added to the bucket of water for irrigation.
