Ask a Master Gardener
Question: What is the "shorter" phlox that is supposedly mildew resistant?
Answer: Phlox paniculata Flame series is the shorter cultivar you are referring to. It comes in coral, light pink, lilac, purple, pink, violet, white and white eye (which has a yellow center). The Flames range from twelve to twenty inches tall and eighteen inches wide. Bloom time is July and August and the plant is hardy to zone and -30F. As with all phlox, morning watering is best; and even though it is mildew resistant, try not to get the leaves wet. Consistent watering and moist soil in full sun is best. Deadhead to promote more blooms and fertilize twice a month.
Question: Is this a baby dragonfly?
Answer: The dragonfly, Anisoptera, is an arthropod and has an incomplete metamorphosis; egg - usually laid underwater; larva - free moving water-dwelling nymph, and adult. There are several nymph stages with some having gills and eating a variety of underwater insect larvae, including bloodworms (which are often found in koi pond filters and turn into midge flies) and mosquitoes. The nymphs spend a good deal of time in the water and then crawl out onto a rock or plant stem to shed their larval skin to emerge as an adult dragonfly. The adults feed on insects including mosquitoes, consuming several times their body weight daily. Depending on the variety, dragonflies live from egg to adult from six months to six or seven years, and not just one day as many people have heard. Yes, this is a baby dragonfly!
Question: Do I need to buy new tomato plants for a fall harvest?
Answer: Some crops that were planted in the spring garden that may continue production into fall are tomato, okra, pepper, sweet potato, cowpea, and New Zealand spinach. These plants may produce excellent yields in the later fall season if given proper care. If tomato, okra, or New Zealand spinach plants are too large for the space, prune them to reduce their size and stimulate growth. They should also be fertilized, watered, and mulched.
Question: I am starting a few of my fall crops from seeds. Have any suggestions?
Answer: Seeds may be started indoors or placed directly in the garden. Most seeds should be soaked overnight, except for beans and peas, to hasten germination. Seeds left over from planting the spring garden may be used if they were stored in a cool, dry location or in a refrigerator or freezer. Use a starting or germinating mix and plant seeds to the proper depth as noted on the seed package in a plastic seed tray or similar. Cover with soil and water with a misting bottle to prevent the floating of seeds. Use seed tray cover or plastic bag to keep moisture in and place in a cool dark location, except for lettuce and celery seeds which require light. Thin seedlings after first set of true leaves emerge. Remember to 'harden off' or place the new seedlings in the sun for a couple of hours a day for a week and then increase exposure to sun and wind. If planting directly in the garden, dig the row trench a little deeper than normal and place seed on bottom of tunnel and cover with appropriate amount of soil. Irrigate with drip hoses on row mounds and then cover rows with a screen mesh for protection from sun and heat. For more information click here for Fact Sheet 6009.

|August Lawn and Garden Tips |
- August should be the last month
to fertilize Bermuda and zoysia turfgrass. Do not fertilize fescue lawns until
it cools in September.
Apply preemergent herbicide to
prevent winter weeds such as Poa annua and henbit in late August and early
September. Consider products containing either prodiamine, pendimethilin or
Our hot dry weather is stressing
lawns. Gradually raise the mowing
heights on Bermuda lawns to 1.5 to
2". For cool season
grasses raise to 3". Be sure to
sharpen or replace mower blades.
Continue planting a fall
vegetable crop, contact Master Gardeners for recommendations.
Divide and replant spring blooming
perennials such as iris and daylilies in late August if needed.
Most plants need 1-2 inches of
water per week in one or two applications, applied in early morning.
Discontinue pruning and dead
heading roses in mid-August to help initiate winter hardiness.
Water your compost during
extremely dry weather to keep it active.
Turn the pile to generate heat for proper sterilization.
Water turf grass less frequently
but for longer periods to stimulate deeper root growth.
Your younger trees and shrubs
will grow faster and stay healthier if you keep them mulched and if you control
the Bermuda grass around them with a Glyphosate herbicide such as Round-up.
Read the label carefully to avoid harming desirable plants.
Spider mites flourish in hot,
dry weather. Often you can use a
spray of water to knock mites off plants.
A fungus disease called "brown
patch" may infect and severely damage cool season grasses such as tall fescue.
Homeowner available fungicides are poorly effective.

|Shrubs for Fall and Winter Color|
Many folks don't
realize how the proper selection of shrubbery can improve their home's landscape.
Selecting shrubs by height, width and shape as well as well by foliage color and
flowers, can make a great
improvement in your landscape. The ornamental and
floral characteristics may vary from shrub to shrub, but remember that for each variety of shrub, their blooms or colorful foliage will
occur at the same time each year. This consistency will help in making the right selections for your
landscape and should make it easier to implement an attractive landscape plan.
Now would be an excellent time to choose and plant shrubs that
will provide color throughout the fall and winter months. The Oklahoma State University's
"Selecting Shrubs for the Landscape" is an excellent source of
information on shrubs of all kinds. Click here for Fact Sheet 6439. Pages
4 & 7 describe winter and fall colors. This Fact Sheet is also available at
the Master Gardener offices in the OSU Extension Center.
