Revitalization movements, spirea style
Back in June, the spirea hedge was rambunctious with bloom. Now that that excitment is over, it's time to start pruning, so that next spring's blossoms can set on this year's wood.
All the authorities say to clear out deadwood and cut back about 1/3 of the branches each year to spur new growth. I usually have time to don a long-sleeve shirt and wield my loppers against a mere fraction before the weather turns too hot for pruning in protective gear. This year, the cool weather has extended the season.
Earlier this spring, I clipped off some dead spirea twigs to serve as supports for a few sweet pea plants. How very eco-friendly, I thought: recycling the old to benefit the new.
However, with our recent cool, rainy weather, those spirea twigs have stirred from the dead and suddenly burst into leaf and bloom. Are they flowering on last year's wood, I wonder, or on this year's? Ahead of the game, or just catching up?
