Episode 48: the Temperate House at Kew Gardens

One of the best ways of learning how to care about your houseplants is to find out more about how they live in their native habitats. If you can't go and visit them in the wild, a trip to a botanic garden such as Kew in London is the next best thing. The Temperate House at Kew is a huge Victorian glasshouse that's home to thousands of plants from temperate climes, including many plants you'd recognise from your collections.

The Temperate House reopened to the public last week after a five-year restoration programme, so I went along to see the transformation. In this episode you'll hear me getting excited about a gully of tree ferns, an interview with Temperate House horticulturist and houseplant fan Jess Snowball, and more. Below are some links to help you find out more... 

Just before I left Kew, I bumped into the legendary plantsman and Kew horticulturist Carlos Magdalena, whose book The Plant Messiah is a wonderful read. Tragically my sound recorder gave up the ghost after just five minutes so I didn't manage to get all of our chat on tape, but if you want to hear what I did manage to salvage of my interview with Carlos, become a Ledge-end by pledging $5 or more a month to On The Ledge via Patreon.

Also on Patreon right now is a new episode of On The Ledge: An Extra Leaf, my subscription-only series for Patreon subscribers. You can hear an extract from my chat with aroid expert Dave The Plant Guy aka Dave Janas about mystery Monsteras in this episode to whet your appetite. 

Question of the week

Pam wanted to know whether she can keep a plant happy in its pot and not have to upsize it. She writes: "For instance, I have a bird's nest fern that I love on my desk in it's pink pot but know that it could use a new, larger home. Can I simply cut the roots back, give a dirt refresh and keep it in the current pot? Or, will it get depressed on me and die off?" I advise that as bird's nest fern is an epiphyte, it doesn't have a big rootball so will probably be ok in the same pot for several years: another option for houseplants that aren't epiphytes (or epiphytes that really have got too big or their container) is root pruning or top dressing. There's a good piece on root pruning in this New York Times piece and the Laidback Gardener has a good post on topdressing.
