Answer: You can prune your junipers now but don't wait until mid-August. If you prune them too late in the season the new growth won't have a chance to harden off before cold weather arrives and you'll end up with a lot of winter damage.
The streaks on the foliage of your gladiolus are probably from thrips. These tiny insects damage the leaves and the corms. You can dig the corms and treat them with an insecticide this fall or you can wait until next spring when the plants are about 6" high and spray with an insecticide such as Bayer Advanced Garden Multi-Insect Killer. Repeat applications might be necessary so be sure to follow label directions. Good luck with your garden.
