Water roses in the summer but don’t fertilize them. The large heat of summer can be difficult on roses. Their blossoms are smaller and frequently burn in the heat. Roses frequently enter summer dormancy, which means that they cease blooming altogether, which is normal.

Brown, crispy stains on outer leaves or browned tips about the needles of conifers are signals your shrubs and trees need a deep drink of water. It’s possible to deep water them by using a hose onto a slow drip around the drip line (where the outer branches end)of every drought-stressed plant.
