In part 2 of episode 6 of the Garden Revival BBQ, Passi, Zappy and IG answer gardeners’ big burning questions. We talk about plants’ circadian rhythms, improving clay soil, plants that have botanists bewildered and whether plants like sugar as much as IG does. Zappy explains rose replant disease and Passi names the plant he has no upper price limit for buying. The audience faces off against IG’s garden riddles and mention of potatoes is shoehorned at the end.
