Since the pots are plastic, they are not breathable. I made enough holes at the bottom to let the excess water seep out.
Some time ago, I made some, 1/4 of an inch, holes.
But when I watered it with nothing in it, some of the water was retained along the sides(since the bottom is slightly curved inwards). So I made some more, even smaller than 1/4 of an inch, holes. Now much of the water is removed, but not complete. I will show some pics:
More holes I made(looking inside the pot):
Water retained(I hope it is clearly visible):
Now comes the aeration/breathability. Should I make any holes on the side of the pots? If yes,
- How many?
- How much bigger/smaller
- In what manner(refer to final pic with four pots with yellow dots that represents holes of diameter smaller than 1/4 of an inch)?
Should I even bother? Will that be good or bad for my plant and soil?
