I have a large (70L?) moulded plastic pot which is filled with topsoil, and has a freshly planted lilac bush in it. I had noticed this pot did not have drainage holes at the bottom, but had thought that the large volume would allow for a fair amount of water to be locked away in the soil.
I've quickly noticed that I am getting a fair amount of standing water on top of the soil, even after fairly modest watering.
Should I drill drainage holes in the bottom of this pot, or is there another suggestion on how to deal with this situation?
