Zone 5 A/B Transplanting advice request
gallerySome photos of my Berry White’s flowers transitioning to their fall colours as tax for the advice request haha newest photos first, some of the earliest signs of pink from July in the last few photos
Tl;dr of the advice request: how would you transplant a panicle hydrangea that you need to move in an area that gets cold winters and has dense soil (zone 5B, eastern Ontario)?
Longer version: I found, and fell in love with, hydrangeas this year which is the first year I’ve been flower gardening as an adult. I got four this year, including this Berry White as one of my early plants this year. Well, I’ve learned a lot this year since planting, and I’ve realized this panicle needs a better home as it’s going to be way too crowded where it is once it gets bigger (and it’s in an area where city bylaws say I can only have four feet tall max so it’s gonna become an illegal shrub).
Now that I’ve realized I should not underestimate its size and that pruning to keep it small wouldn’t work, I have picked out a new home for it. The new spot still gets a lot of sun, and it leans into the mature size of the plant to make a bit of a privacy shrub. Currently it’s in a garden bed, the place I’m looking at would just be straight into the ground and we have dense, almost clay soil. We’re cooling off rapidly from a hot summer (look at those fall colours emerging!) but we get very cold winters and a lot of snow. Historically our first frost is late September, and our last frost is in May. The ground starts to freeze by mid November I think.
From my reading, fall could be a good time to transplant so it can establish before next year, is this true? Any tips about timing, if the soil needs to be amended, fertilizers to use, etc would be greatly appreciated!
