Gardening trends for 2020, houseplant rampage and gardening with sight loss

This week our resident gardening guru Guy Barter gazes into his crystal ball to make some predictions for the year ahead in horticulture, before heading to the Glasshouse at RHS Garden Wisley to come face to face with some very naughty houseplants. So naughty in fact that they've taken over an entire Victorian house, elbowing the human occupants aside in a verdant invasion that's sure to delight visitors. Garden Manager Emma Allen braves the bristling bromeliads and chess-playing cacti to take Guy round this quirky new attraction. Plus part two of our visit to gardening charity Thrive, who help people with disabilities or ill health to keep on gardening. Training, Consultancy & Education Manager Damien Newman gives useful advice on ways to garden when sight loss becomes an issue.
