Foxglove tree

As this tree will reach forty feet, I'm not suprised it was growing fast! It flowers in late spring - but on wood made this year; by pruning now, you have removed any wood that would have carried flowers. In future, if you need to prune it, do it as the flowering finishes.
Back in January I wrote two blogs on pruning. You might like to look at them to help you

We prune ours back to the ground every February. Then we allow only three buds to grow. We get no flowers, but the leaves get to over a metre across. It grows to about 12 feet each season.
