It’s the time of year when we do the houseplant shuffle - that desperate effort to get all the houseplants safely inside before they are ripped apart by winter winds or rendered crinkly with an overnight frost. In this episode I demonstrate how I get a plant ready to come inside, and talk to Norwegian nursery owner and houseplant collector Tommy Tonsberg about how he gets his plants through the long winter.

How to prep your plants for winter

  • If plants have been holidaying outdoors, check them thoroughly for pests - that means looking at leaves top and bottom, both sides, taking the plant out of its pot and checking for any hitchhikers such as slugs, snails and root mealies.

  • If you do have an infestation, clear them off by whatever means necessary (wiping with a damp cloth and insecticidal soap sprays for instance) then quarantine the plant once inside so it doesn’t pass any pests on to other plants.

  • Plants that have put on a lot of foliage growth over summer can be cut back if necessary to fit into their space: this also gives the plant less leaves to support over winter. You will find that this reduces leaf drop and encourages the plant to stay bushy.

  • Finally, do listen to episode 18 of On The Ledge which talks specifically about prepping cacti and succulents for winter.
