Having never bought pots without holes in them before—still not understanding, to be honest, the point of them—I’d already potted up two big (50cm across at the top) pots with broad beans before realizing that they were starting to get waterlogged in bad weather.
Not wanting to lose the beans, or to have to repot them (I have nowhere to do it, for a start) then I decided I might try drilling the pots with the plants in situ. But how to do so, without ending up covering myself and my electric drill in water and mud?
Here’s the result of my attempts, in one of the two pots:
You can see I made a small initial drainage hole on the side. Doing this really helped avoid getting a considerable amount of foul-smelling water on the drill’s electrics! I then tipped the pots slightly towards this hole, to let as much water drain out as possible, before tipping them quite sharply in the opposite direction to drill the three holes underneath.
The soil has started to dry out completely in a few days: while I won’t be watering them yet, it’s a relief now to know that the roots will be getting a little air, and hopefully no rot.
