Don’t overheat. Late summer is sure to bring us plenty of heat and humidity, so try to get your gardening chores done early in the day or in the evening.
Keep container plantings in peak form with regular deadheading and dead-leafing. Continue watering and fertilizing too.
Order and plant new bulbs of colchicum (Colchicum spp. and cvs., Zones 4–9) and fall-blooming crocuses such as Bieberstein’s crocus (Crocus speciosus, Zones 4–9) for autumn color.
Take cuttings of coleus (Plectranthus scutellarioides, Zones 10–11), scented geraniums (Pelargonium spp. and cvs., Zones 11–13), and other tender plants that you want to bring indoors to overwinter for next year.
Collect seeds of your favorite flowers and edibles to share with friends and swap with other gardeners.
Sow cool-season edibles such as beets, kale, lettuce, radishes, and spinach for a fall harvest.
