My oversize planter that I made in wood shop 1,000 years ago is ageing.
I made too many drain holes initially, and would like to plug some of them, because the handyman who refinished my concrete porch blocked where water used to drain out of the porch; now it pools where the planter needs to be.
I emptied the planter and storing soil in buckets while I figure out situation.
I cut a strip of roll roofing to line the inside. I want to leave only the minimum holes needed for drainage on L and R side.
What should I use to plug the holes that is not too expensive or time-consuming?
It's been suggested that I use pieces of roll roofing to Gorilla glue the unwanted holes shut. Was also told that wood ? filling? would also be expensive, so hoping for a low or medium-cost solution.
