Make an Herbicide Shield
If you're using an herbicide such as glyphosate in established flower beds, you will need to protect desirable plants from accidental contact with it. I use an old discarded cookie sheet (now clearly labeled "Garden Use Only") as an impermeable, easy-to-carry shield for the job.
Take Tip Cuttings
Now is the time to take tip cuttings from deciduous shrubs. To take a tip cutting, cut a 5-inch piece of stem from the tip and remove lower leaves. Dip the cut end in rooting hormone and insert in dampened soilless potting mix. Water once, cover the pot with clear plastic to maintain humidity, and set in a bright spot out of direct sun. Check for roots in about a month.
Create Weed-Free Pathways
Create weed-free pathways in your garden by laying down brick, stone, board, gravel, or organic mulch. Lay a weed barrier such as landscape cloth beneath the walkway material and place edging around the walkway to help keep weeds out.
Self Seeded Flowers
To promote strong growth and avoid overcrowding, thin seedlings of flowers such as cleome, cosmos, morning glory, nicotiana, purple coneflower, black eyed Susan, viola, and columbine. Remove plants by snipping them at ground level, or gently transplant them using a trowel. To transplant, dig a generously sized rootball and water well before and after planting.
Divide Pond Plants
In a water garden, aggressively spreading bog plants such as parrot's feather, cattails, and water lilies may outgrow their containers over time. To remedy this, unpot and divide the plants, then replant them in individual pots. Share the extras with friends or start another pond garden.
