Deep Watering with Pop Bottles. Verdict? Not So Deep
May 29, 2008
I decided to try deep watering my tomato plants using 500 ml pop bottles filled with fish emulsion fertilizer. I rinsed out the bottles, filled them up, capped them off and poked three holes in each on one side with a push pin. I made a long depression in the soil with my finger and set them push-pin-hole down. They looked pretty good:
I thought the fertilized water would slowly drip out but it’s been a day now and the bottles are still fairly full. I lifted a couple up and checked the soil underneath and it wasn’t noticeably damp. There was a bit of dampness but that was probably from me squeezing the bottle when I picked it up. Maybe I need to make bigger holes. Maybe I need to elevate the bottles off the surface of the soil so that the holes don’t get plugged up.
