Should I put slate chippings in bottom of pot?

I am potting a bamboo, and have put slate chippings for drainage at the booth. After the first watering the water just sat on the top like a puddle. I had a quick google as worried chippings was not ideal- but didn’t have any gravel about. But now it seems people don’t bother putting anything in the bottom as does more harm than good? Any thoughts?
Shall i unpot the bamboo to remove the slate? Or leave it be? Thanks

    Bamboos are very thirsty plants so I would leave them but keep an eye on the pot. I’ve found that with new compost the first watering can sometimes sit for a while before it drains through.  If the compost stays water- logged and feels very wet after been left unwatered for a while then you’ll know that the chippings aren’t helping but I would be surprised if they caused that much of a problem.

  • Thanks for the reply. Yes the water seemed to sit for ever on top on the pot and I couldn’t see it run out the bottom so wondered if I’d made a mistake, and if to pull it out before it gets compacted . Il leave it for a few days and see what happens

    Sometimes the compost can form a crust, and the water takes ages to sink.
    It can help to break up the top layer with your fingers before watering.
