Drainage holes

I have to repot my plant into a larger container. It is currently indoors. I bought a 40cm and 50cm pot but they don't have drainage holes. Are the containers so big that they do not need them any more?

If I do have to add drainage holes, my current "saucer" is too small. Any ideas what else I can use?

Thanks

 

I presume what you have is a decorative planter, which would normally be interplanted with another container.
I always have drainage holes. I have, in the past, actually drilled holes in planters where there was none.
If there are no drainage holes I believe you will, over time, end up with stagnant water and root rot.
I await more expert responses with interest

 

For decorative containers with no holes I put a smaller pot inside, and and inch or so of gravel in the bottom [EDIT: of the decorative container]. Make sure the gravel doesn't completely fill up with water so the pot itself does not sit in water, but other than that as the water evaporates from the gravel it will provide more humidity for the plant

If you want to plant directly into the decorative container it will need to have drainage holes

 

For my indoor plants I use a plastic plant pot (the type they come in) then put that inside the planter.

 

Whenever a construct an procure a new likly looking planter I always putan inch of croc toped gravel and its at this level I drill the dainage holes plus if its a deep contaner and the roots of the plsnts fairly short I use old hemp rope as I wick also put in a tube down the middle to water the contaner saves water and sinkage compacting the roots

 

I've started using airpots

strange, as the bottom plastic disk has huge openings .... I asked the guy in the shop if I am supposed to place pebbles to stop the compost from falling out

he laughed and said no stones.... don't panic .... the compost won't fall out ... just don't overwater


so far, so good ....

but back on track, don't overwater .... if the water runs out from the bottom of the pot (if it has holes), that means that you are overwatering and flushing out the nutrients/good stuff
