7 Perennials You MUST Divide in August (And 6 That Die If You Try)

🔗 Get a beautiful perennial garden with less watering, fewer costly mistake from Henry’s Garden Blueprint: https://henrysgardensecrets.com/ There is a clump in your garden that has gone hollow in the middle - green round the edge, dead in the center. That plant is not sick and it is not old. It is strangling itself, and August is when you fix it. But not all of them. Six of the plants in the second half of this video will die if you put a spade through them, and people do it every year in good faith because a list somewhere told them to. Two more that keep showing up on divide-in-August lists should not be on those lists at all - I explain why and what the rule underneath it actually is. Everything here is checked against university extension guidance rather than repeated from other videos, and where the extension services disagree with each other I say so instead of picking the tidy answer. One safety warning in this video that most gardening channels leave out entirely. It is at number two in the second half. Please do not skip it. Thirty-five years of notebooks. Thirty-four of them behind a garden center counter. TELL ME WHERE YOU GARDEN Which of these has the dead middle at your place? Drop the number in the comments with your US state next to it. I read every one. Division timing swings hard by region and the pattern tells me what to cover next. SUBSCRIBE One video a week. What earns its place in an American backyard, and what only looks good on a bench in April.
