As I watch the weather for this week with 90+ degrees all week, I visualize what my perennials and hydrangeas will look like by Friday. The answer is leaves will be crispy and some perennials may be dead, especially they ones I just planted in late Spring.
Out of all the plants I have worked with I make the most comments while working vines. My words are usually full of apologies for breaking off delicate tendrils, or trying to get vines to twine around too tight a wire.
Free pruning is a dying art in the landscape industry because most new landscapers are not trained in doing it. Free pruning correctly also takes a longer amount of time which most customers don't want to pay for.
