Prune dead and diseased plants. Deadhead (remove faded flowers) annuals and
perennials to promote flowering which also keeps plants compact by inducing
branching. Finish trimming hedges or shrubs not grown for flowers. Pruning after
August will only stimulate new growth that won’t be tough enough for winter and
cause freeze damage. Don’t prune spring flowering shrubs because you’ll nip next
year’s buds.

Always mow dry grass as wet tends to tear and it can clog your mower. Wear
sturdy shoes and eye protection.
Use a mulching lawnmower to let clippings fall back into the grass to nourish
the soil. Mow once a week except for Buffalo which can be mowed as needed.
Cutting more than one-third height of lawn at any one time can lead to heat
stress in sunny areas while shady areas need only one-fourth cut off. It’s also
a good idea to raise the height of your mower as much as possible when it’s hot
and dry which will leave the grass taller allowing for more moisture retention
of the soil. Check lawn mower blade as stringy, ragged grass ends may indicate a
dull blade that makes for an unattractive appearance especially on Zoysia grass.
Check spark plugs, change the oil, clean the air filter and check the fins on
the engine cooling fan too. If you find your mower is difficult to start, it may
be old leftover gas that has collected moisture.

Weed all beds, roots and all, as soon as they appear. We like to weed after
watering so they come out easier. The best prevention for weeds is watering,
fertilizing, mulching and turning (cultivating) the soil. It’s better to pull
them out manually rather than relying on herbicides because it’s healthier for
us and the environment.

Inspect your system for leaks and correct positioning for best coverage. You
might also want to add a moisture sensor to your system which prevents your
system from watering if a pre-determined amount of rain has recently fallen.

Fertilize flowers around the 3rd week.
Marigolds are good heat tolerant plants. (Gold and these yellow beauties
interested the explorer Hernando Cortez so much that he named them Mary’s Gold
originally.) Best time to plant them in late August for bloom shows in September
and October.
Roses can be selectively pick pruned and then fertilized in late August for the
last time this year with a slow release fertilizer with a high level of
phosphorous which promotes root growth, larger blooms and disease defense.
To revive fading caladiums, discontinue water or fertilizing for about 2 weeks
then apply one tablespoon of 5-10-10 fertilizer per sq ft and well thoroughly.
Stop pinching back the mums now so the buds can get ready for a fall display.
Asters in sun and daylilies needing 6 hours of sun a day can be added to the
garden now.
Towards the end of the month you can begin planting wildflower seeds.
Make sure your container plants are watered, fertilized and in the right sun or
shade spot.

Mites and aphids can be discouraged with blasts of water or insecticidal
soap spray although lady bugs and lacewings are even better. Direct spray upward
from beneath the plant or you’ll miss most of these pests. Products to control
pests are numerous so choose the lowest toxicity and the right blend for your
particular pest problem.

Don’t prune or trim off the lower branches of newly planted trees. It’s
better to let young trees become established before you remove any limbs.
Trees planted within the last 12 to 18 months need special attention and should
be hand watered every 5 to 7 day unless it rains.
The best place to water trees is its dripline which is the ground under the
outer tips of the limbs where all the feeder roots are located. A soaker hose
left for hours in this spot will help your trees be healthy.
Prune back salvia greggi by one-third to encourage blooms and keep at a
manageable size.
If powdery mildew or black spot has appeared on the leaves of your shrubs or
small trees, try using neem oil or potassium bicarbonate.
Crape myrtles planted in shade have this problem and should be transplanted to a
sunnier spot when they are dormant during the winter.
Wasps eliminate fall webworms so leave their nests alone unless they are a real
problem.
Don’t trim Glossy Abelia but enjoy their flowers and natural weeping habit.
G R O U N D C O V E R S
Keep well watered. Use lawn mowers or weed eaters to trim.

Wait until October to apply your fall fertilizer. Thoroughly soaking your
lawn and the ground beneath with four to six inches of water will encourage
deeper root systems which will then require less waterings.
Thoroughly soaking your lawn and the ground beneath with four to six inches of
water will encourage deeper root systems.
Chinch bugs usually appear in sunny areas next to a drive, curb or other masonry
structure. Over watering and over fertilizing may make your turf more
susceptible to chinch bugs but there are several insecticides available. Treat
just the infected areas and not your whole lawn.
Dig weeds out, roots and all, as soon as they appear. Keeping your lawn fed,
watered and mowed can also help limit weeds.
This is the last month to seed Bermuda grass lawns until next April. Be sure and
water well.
If you don’t have the time or energy to keep up large expanses of turf, you
might consider installing perennials beds, ground cover or walkways on parts of
your lawn. |
