Climate resilient gardens, lettuces, and gladioli

This week we head to RHS Wisley's Hilltop where the science and advisory teams are working tirelessly to come up with solutions to some of the biggest pressures facing horticulture and gardeners today, and few are bigger or more pressing than climate change. RHS advisor Jenny Bowden talks us through an experiment she's working on to find out which plants are best suited to the extremes in summer drought and winter flooding UK gardens are increasingly experiencing. Horticulturist Liz Mooney runs us through the Lettuce extravaganza she is sowing at Wisley's world food garden. And bulb expert Muhammad Hafiz Ullah, gives us a masterclass in growing gladioli Host: Nick Turrell  Contributors: Jenny Bowden, Liz Mooney, Muhammad Hafiz Ullah Links: Choosing plants for seasonally wet and dry soils How to grow lettuces Gladioli Gladiolus trial
