    Tips & tasks – September

    Cut the dead tops of coneflowers, but leave enough for goldfinches to enjoy the seeds.

    Plant cool-weather vegetables for a fall crop: spinach, mustard and turnip greens, radishes, leaf lettuce.

    Start a new lawn of cool-season grass, such as fescue, or refurbish or repair establish lawns.

    Don’t let the soil of newly planted grass dry out. New grass needs about an inch of water per week.

    It’s still warm, so continue to water and weed garden beds as needed.

    Remove dead foliage, spent flowers and other garden debris; replenish mulch as needed.

    Continue to harvest produce, which may be getting a boost now from slightly cooler weather. Keep watering sage, rosemary and other perennial herbs so they’ll be in good shape to get through winter.

    Prepare to bring houseplants back indoors: remove dead leaves, scrub soil from the sides of the pots, treat for insects. Bring tropical plants in before nighttime temperatures dip to 55 degrees.

Time to plant a rose

Question: We want to add roses to our landscape this year. When is the best time to plant them? Is it better to buy bare root plants, or plants in containers?

Rose WebRoses purchased as bare-root plants can be planted in late winter, whenever the soil can be worked. In this area (USDA Hardiness Zone 7a), roses in containers should be planted after mid-April, say the experts at the Nashville Rose Society. Either should grow well and bloom if they’re given the right conditions: lots of sun – six or more hours a day – and good drainage.

Here’s how to plant roses to get them off to a good start:

Before you plant a bare root rose, soak it for 8 – 24 hours in a large bucket of water with root stimulator added. This rehydrates the plant. Dig a hole 18 inches wide and deep. Place ½ cup of superphosphate in the bottom of the hole, and cover it with a mound of soil made up of 1/3 top soil, 1/3 compost and 1/3 sand or perlite. Prune any broken or dead branches or old canes smaller in diameter than a pencil, and prune back any broken or unusually long roots.

Place the roots over the soil mound in the hole and spread them out and downward over the mound. Place the soil mix around the roots to fill the hole about halfway, and pour a gallon of water with root stimulant over the soil and let it drain. After this has soaked in, finish filling the hole up to ground level with soil mix. Cover the soil with mulch to help keep the bush hydrated until the feeder roots begin to grow; remove the mulch gradually as the weather begins to get warmer.

To plant a potted rose (after the last frost date in your area), dig a hole slightly larger than the diameter of the pot and about 18 inches deep. Place ½ cup of superphosphate or bone meal in the bottom of the hole and cover it with 2 inches of soil. Remove the bush from the pot without breaking the root ball (you may have to cut the sides of the pot away) and place the root ball in the hole so that bud union – the knot where the rose was grafted onto the root stock — is just above ground level.

Fill in around the root ball with soil, and water thoroughly with a bit of root stimulator added to the water.
