Bounce Pink Flame Impatiens
A new variety of hybrid impatiens has been introduced and will be available in limited quantities this Spring—the ‘Bounce’ series, along with its larger sister line, the ‘Big Bounce’ series. Both series result from a breeding cross between New Guinea impatiens and traditional Garden impatiens. Like many hybrids, ‘Bounce’ inherits some of the most desirable characteristics from each parent. From its New Guinea impatiens lineage it receives the leaf shape and the larger flowers typical of New Guineas. Perhaps most importantly, though, it also receives the celebrated New Guinea resistance to Downy Mildew.
Bounce white impatiens
From its Garden impatiens parents it inherits the higher flower density, shade-tolerance and spreading habit typical of Garden impatiens. That means that each plant will tolerate more shade and cover a much wider area than will the more upright New Guinea impatiens.
Since ’Bounce’ impatiens, like most New Guinea impatiens, are produced from cuttings and not from seed, they’ll be available only in 4” pots or larger and not in flats of 48. Regardless, ’Bounce’ impatiens will make a welcome addition to the shade garden.
Typical Plant Care Instructions
Rhododendron and Azaleas – Shape as desired soon after flowering, but not later than mid-July since next year’s flower buds begin forming at this time. An acidic fertilizer is preferred. Tiny white stipple marks on leaves indicates feeding by harmful lacebug insects on undersides. Use an insecticide and spray as per directions on label.
Most flowering shrubs – No special care. Trim lightly after flowering. If plants become too tall over the years, remove 1/4 to ¸ total plant height in early spring before leaves emerge.
Most hedge shrubs – When new growth elongates to 6-10″, cut growth in half to promote bushiness. Continue procedure until desired height and width is reached, then trim closely as needed.
Most trees, especially Cherries and Plums – No special care if a shrub. Trim lightly any time as desired. Remove “suckers” (vigorous young shoots growing vertically usually from ground level but also from main branches) as they appear. Periodically cut out branches that rub against others. Check for presence of scale insects on branches yearly (white fluffy egg masses and/or 1/8″ tan shields covering adults). Call spray company for a dormant oil application.
Pines – To keep compact, shear ‘candles’ (light green new growth spikes) with hedge shears or clippers when candles stop elongating and before needles on their sides reach 1/2″ in length. (Generally, the last week in May). Timing is critical. Cut off 2/3 – 3/4 of total length. Look for black inchworms devouring older needles between May 1st and May 25th . Worms can eat entire plant in one week if left undetected. Spray with an over-the-counter pesticide.
Re-blooming perennials – No special care. Shearing off spent flowers after initial wave of flowering fades will promote second wave. Otherwise, will flower sporadically till frost. See below for division.
Many perennials – No special care. Divide and thin out periodically (every 3-4 years) if clumps become too large, unmanageable, or have significant dead portions (especially in the centers).
Most ornamental grasses – Cut down to 4″ in early winter or before new growth appears in spring (early April). Can be divided into sections as large as desired with a spade in early spring after the clump greens up. Discard any obviously dead portions.
We have just replaced one or more perennials, shrubs and/or trees in your landscape. Where possible, we have marked your replacements with a colored ribbon.
Your new plants require special attention for at least 4 weeks after planting, until the root system gets a chance to grow out into the surrounding soil. Until then, THE ROOT BALL WILL DRY OUT WELL BEFORE THE SURROUNDING SOIL DOES. Thus we strongly recommend that all replacements be watered BY HAND until established. PLEASE DO NOT RELY ON YOUR SPRINKLER SYSTEM TO DO THE JOB. IT WILL NOT GIVE YOUR NEW PLANT ENOUGH WATER WHERE IT NEEDS IT – IN THE ROOT BALL.
Please DO NOT adjust your sprinkler system to an every-day schedule simply to water a few new plants or a small patch of new sod. You might damage your established sod and shrubs by over-watering them, and the sprinkler heads may not actually provide enough water to saturate the newly installed plants sufficiently.
Following the watering guidelines below will help integrate your replacements quickly into the landscape:
A. Small Shrubs and perennials – by hand with hose and/or bucket
1. First 2 weeks – Water every other day for shrubs and perennials in full sun, every 2-4 days if in shade. Under extremely hot or windy conditions, you may need to water every day. Treat them like house plants and aim the hose directly into the root ball.
2. Next 2 weeks – Cut down to once every 3-4 days.
3. After 4 weeks – Your new shrubs should be somewhat established. Continue to water every 2 weeks by hand as a supplement to your sprinkler system right up until the end of December and throughout the following spring while the plants have leaves.
B. Trees and Large Shrubs – by hand with hose or bucket
1. First 2 weeks – Water by placing the hose directly on the root ball, then turning on the faucet so that the water comes out in a slow trickle. Let it trickle for ¸ – 1 hour. The larger the tree, the more time needed. Repeat every 3-4 days.
2. Next 4 weeks – Water once a week as above.
3. After 6 weeks – Water occasionally as above during extended periods of no rainfall (or about once every 2-3 weeks) right up until the end of December and throughout the following spring while the plants have leaves.
Your new trees, shrubs, and/or perennials require special attention for at least one month after planting, until the root systems get a chance to grow out into the surrounding soil. A little vigilance in ensuring that each plant receives its full allotment of water during this time is the single most important factor in determining the future success of your plants. Keep in mind that the root balls of your new plants will dry out just like a houseplant even though the surrounding soil appears wet. The best way to check the roots is to pull away the mulch from the stem of the plant and use your finger to scrape down an inch or two directly into the rootball to feel for dryness.
Sprinkler systems, even the best ones, will water some areas better than others. After your landscape has had time for the plant roots to spread out and intermingle (at least 6 weeks after planting), this unevenness in sprinkler coverage is not a major problem. But when the plants have just been installed, some plants may not receive enough water from the sprinklers to survive the critical first few weeks. For this reason it is imperative that you make frequent (daily to every second day) inspections of your landscape so you can spot plants that may be dry, and water them by hand to give them the opportunity to grow roots into areas that get more water.
Following the guidelines below as a supplement to your sprinkler system will help integrate your plants quickly into the landscape:
A. Shrubs and Perennials – by hand with hose and/or bucket
1. First week – Water every 2 days for shrubs and perennials in full sun, every 3-4 days if in shade. Under extremely hot or windy conditions in full sun, you may need to water every day. Treat them like house plants and aim the hose directly into the root ball. Make mental notes of areas that seem to need extra attention.
2. Next two weeks – Water your extra-attention areas as above. For the areas that are not a problem, water once a week just to be sure.
3. After 3 weeks – Your new shrubs should be somewhat established. Continue to water your extra-attention plants once a week by hand until the end of the season as a supplement to your sprinkler system.
B. Trees and Large Shrubs – by hand with hose or bucket
1. First two weeks – Water by placing the hose directly on the root ball, then turning on the faucet so that the water comes out in a slow trickle. Let it trickle for ¸ -1 hour for each plant. The larger the tree and the more exposed it is to wind and sun, the more time needed. Look for special-attention plants. Repeat every 5-7 days depending on weather and sunlight conditions.
2. Next four weeks – Water twice as above during this period.
3. After six weeks – Water those special-attention plants during extended periods of no rainfall occasionally as above until the end of December.
Fall Color Ideas
Fall is not just for mums anymore. Your choices for Autumn and Winter color are far more varied than just a few years ago. Try combining mums with new varieties of Ornamental Kale and Cabbage, Millet (a red-leafed, wheat-like flowering grass), the more compact varieties of Maiden Grass, and Algerian Ivy to really brighten up your pot and bed arrangements.
And once Thanksgiving comes, pop out the spent mums and add a mix of white Birch stems and Red-Stem Dogwood branches for height. Use layers of evergreen boughs like Spruce and Pine as a cover for the soil. If this winter is anything like the last three years, you’ll have color right up through New Year’s Day.
Fall Gardening Tips
Around September 30th: Shut down irrigation clock and run manually only when needed
September 20th through October 10th: Time to plant fall Mums
September 20th through Thanksgiving: Time to plant Ornamental Kale and Cabbage
October 1st through Christmas: Time to plant spring bulbs.
November 15th through December 1st: Time to apply your last lawn fertilization.
November 15th through December 1st: Time to replace spent mums with Holiday color.
November 15th through December 15th: Time to remulch perennial beds.
Thanksgiving through March 15th: Time for winter pruning of all trees and shrubs
Early fall, from early September through late October, is a great time to put plants in the garden. The shorter days and cooler air temperatures reduce the demand for water and keep plants from producing an abundance of new leaves, while the still-warm soil promotes root growth. Thus plants have plenty of time to build a healthy root system and get established before the onset of winter.
Late August through mid-September is also an ideal time to divide and replant those perennials that have become overgrown. Irises, Hostas, Daylilies, Coreopsis, Black-eyed Susan, summer Phlox, and Astilbe are just some of the perennials that can be divided at this time.
Now that it’s August, your summer flowers may require a little additional care to keep them attractive and blooming all summer long. Following the guidelines below will ensure a continuous flower display.
Some annuals require a little grooming now and then in order to look and perform their best. Grooming includes removing spent flowers before they begin to form seeds, called ‘Dead-heading’.
Annuals that benefit most from deadheading — which promotes continuous flower production— are Dahlias, Zinnias, Snapdragons, Salvias, Geraniums, and larger-flowering Marigolds.
Pruning off leggy and overly-long branches of many plants promotes renewed flowering and plant compactness. Don’t worry about removing too much; even a severe haircut will become unnoticeable after a week or so.
Petunias, Verbenas, Scaevola, Calibrachoa, Bidens and Ivy Geraniums benefit from this, as do trailing foliage plants.
Watering during hot, dry months is critical, especially for plants in containers. Do not let your plants dry out! Excessive dryness causes leaves to become stunted and yellow, and reduces flower production. When you water your pots, wet the soil thoroughly until water runs out the drainage holes at the bottom. Repeat until thoroughly soaked. Check pots daily, as high summer temperatures and windy days will dry out your containers more quickly.

Late June: Time to remove pansies and other cool-weather annuals and replace with summer flowers.
Spring Bulbs: Save or Remove?
Spring-flowering bulbs are loosely categorized into two groups in our climate: those that come back reliably every year, and those that don’t.
Daffodils, Narcissus, and most hardy woodland bulbs usually return year after year, as long as their leaves are allowed to turn brown after flowering before being cleaned up.
Tulips and Hyacinths, however, don’t stay green long enough to consistently produce flowers for the following season. Two or three seasons of brilliance is all you can expect, so it’s a good idea to remove them, bulb and all, right after the second year of flowering, while you can still find them. You can then plant new ones in the fall.
