Diss: Gravel Gardens, Camellia Care and Ways to Weather Drought
In a candid episode of Gardeners' Question Time, veteran gardener Bob Flowerdew delivers hard-won wisdom on surviving drought in East Anglia’s notoriously dry, clay-heavy soil. He dismantles common gardening myths—like feeding lavender, which he calls a 'waste of money'—and champions radical water conservation: using geotextiles, harvesting rainwater in interconnected butts, recycling greywater, and watering plants through buried bottles or trenches. His most provocative claim? 'Founders die from overdose of opportunity, not starvation'—a metaphor for gardeners overcommitting to too many plants. The panel also tackles persistent pests, revealing that sooty mould is not the enemy—it’s a symptom of scale insects, which require targeted insecticides, not fungicides. Bunny Guinness and Christine Wharton share deeply personal stories of how plants serve as living memorials to lost mentors and family, turning gardens into emotional archives. The episode ends with a powerful reminder: resilience isn’t about perfection, but about learning from failure, keeping records, and letting plants carry memory forward.
Use buried plastic bottles or trenches to deliver water directly to roots—reducing evaporation by up to 70%.
Never feed lavender; it thrives in poor soil—drainage is 100x more important than fertilizer.
Sooty mould is cosmetic—control the scale insects first with systemic insecticides, not fungicides.
Remove plastic mesh root containers when potting on—roots get trapped and fail to establish.
Plant drought-resistant species like figs, sea kale, and pelargoniums to reduce watering needs by 50%.

Cuttings: Timing, Tolerance, and the Myth of Failure
“If a nursery took 10 cuttings and nine died, it's a failure. If you take 10 cuttings and you get 10 take, what are you going to do with eight of the plants? Sell them at the finish line.”
Sooty Mould: The Real Enemy Is the Insect, Not the Fungus
“You've got to go on a scale insect hunt from the sound of it, Nicky. But that's what it is.”
Gravel Gardens: No Membrane, Just Smart Design
“I've got quite a big area of gravel which I don't call a gravel garden. It's a courtyard that's got a lot of paving of gravel in it and I... would hate a membrane.”
Bob Flowerdew’s Drought Survival Toolkit
“Nothing beats somebody going round with a watering can and a thumb and making sure you've done it properly.”
“And this is what plants can do for us. They carry things on from people who are no longer with us, but they are there still in spirit.”
