Pre-emergence Weed Control
By Shawn Banks
|Have weeds been a continuous plaguing problem in your yard? Year after year they seem to come back, appearing in different places around the landscape. What is a homeowner to do?
Weeds that die in the winter, but come back each summer from seeds are called summer annuals. Crabgrass, prickly lettuce, spotted spurge and common ragweed are examples of summer annuals.
The key to controlling summer annuals is preventing their seeds from germinating. This means pre-emergence control of the weed seed. The most common control method used today is applying chemicals. There are several different pre-emergence herbicides on the market. Some are listed only for use in turf areas; others are listed for use only in ornamental plantings; there are some listed for use in both turf areas and ornamental plantings.
Words of caution when using any chemical: ALWAYS read and follow the label directions. Manufacturers often change labels as chemicals are improved or altered.
There are two basic ways a pre-emergence herbicide works. These chemicals will target the radical (the root that emerges from the seed) or the new stem as it emerges from the seed. The objective is to burn or injure the plant before it begins growing. In either case the chemical needs to be in the soil prior to the seed germinating or the chemical can’t do the job it was designed to do. Apply these chemicals in early February for best results.
Another method of pre-emergence weed control is to use cultural methods of control. This means developing a healthy, thick turf canopy. For those growing tall fescue this also means cutting the lawn at a height of 3 to 4 inches to prevent sunlight from penetrating to the soil where the seeds are.
With summer turf where the lawn is dormant at the time the seeds are beginning to germinate it becomes a little tougher. Proper fertilization and mowing during the summer is most important. A thick canopy even in a dormant lawn will prevent some seeds from receiving the light they need to germinate.
Lawn maintenance calendars can be found on the TurfFiles website or they can be obtained at the local N.C. Cooperative Extension. These calendars give information on the proper height to mow your turf and when to begin a fertilizer schedule.
In landscape beds a fresh layer of mulch at a thickness of 1 to 2 inches will cover and seeds. Excluding the light from the seed prevents germination. The mulch also spruces up the beds and makes the fresh spring colors really stand out.
A soil sample submitted for testing is another cultural practice that can be used to prevent weeds. If the soil has the correct pH and fertility for the plants to grow, they will form a nice canopy over the soil that will also exclude sunlight.
There seems to be a pattern emerging. To prevent weed seed from germinating, exclude sunlight or apply chemicals. Either of these two methods will work well as a pre-emergence weed control method.
Witchhazel – Hamamelis sp
By Patty Brown
To add some bright color and fragrance to your winter landscape, consider planting a witchhazel or two. Be forewarned, though! You may have some difficulty deciding which witchhazel to choose.
Depending on the species and variety, witchhazels are loosely spreading shrubs or small trees, ranging from 6′ to 15′ tall and wide. Bloom times vary from late fall through early spring, and its small flowers — in yellow, gold, orange or red — look somewhat spider-like. In addition to their striking color in the landscape, many witchhazels are very fragrant. In addition, the foliage of these deciduous shrubs puts on a good show in the fall, when the leaves of most varieties turn yellow with highlights of red to purple.
Common witchhazel is hardy from zones 4-9 and includes native varieties Hamamelis virginiana, which flowers in the fall, and Hamamelis vernalis, which flowers in late winter.For the most reliable flowering, John MacNair, NC State Cooperative Extension Specialist, recommends cultivars of Hybrid witchhazel (Hamamelis x intermedia), hardy in zones 5-9.
Witchhazels do best in moist soils with a little light shade, although they will tolerate full sun. To get the most enjoyment from their flowers and fragrance, plant them near a path or walkway. Maintenance is easy; witchhazels require only occasional pruning to improve their shape.
So how did such a lovely little tree get such a funny name? Witch has its roots in the Old English word wice, meaning bendable. And hazel? In England, hazel twigs were used as diving rods to find water, and early settlers in America are thought to have used the branches of witchhazels for this same purpose.

For all gardeners: Lin Frye at the Arboretum at JCC is looking for some gardening stories from people here in Johnston County for their oral history project. If you have been gardening for a while here in Johnston County she would like to speak with you about your experiences, why you got started gardening, and what the benefits have been to you. This could be any kind of garden including vegetable, glower, or some specialty garden. Call Lin Frye for more information at 919 209-2052.
Big Eyed Bugs
Big eyed bugs get their name from the over-sized eyes they have on their heads. The eyes are so large they cover part of pronotum (the area just behind the head). There are three different species of big eyed bugs found in the US and all three are listed as having North Carolina as part of their range. The three species are Geocoris bullatus, G. punctipes, and G. uliginosus.
Big eyed bugs range in size from 1/8 inch to ¼ inch in length and are roughly oval in shape. They are predators of several other insect species including small caterpillars and caterpillar eggs, fleahoppers, lygus bugs, mites, thrips, and whiteflies. If prey is in short supply they may also feed on some seeds and plant juices, but are not considered a plant pest.

What is ready to harvest in February? SPINACH! Did you plant any in fall? I hope so!
Spinach – some people say BLECH! Poor spinach – it gets a bad wrap. Spinach is very tasty- you just need to prepare it right. Not only is it good- it is so good for you. We all remember dear old Popeye eating his (slimy) can of spinach and immediately having the strength of an army in his biceps, (good subliminal marketing for kids to eat their spinach). Hopefully we have all grown up now and enjoy fresh or fresh frozen spinach and all the many benefits there are for us. Those thin leaves of green leafy spinach are full of vitamins and minerals. Check this out- Vitamin A, B, C, K, Iron, Calcium, Iodine, Magnesium and fiber! Did you know spinach is 49% calcium? WOW! If you can’t get it from a u-pick farm, http://www.pickyourown.org/NCharvestcalendar.htm
or your own garden, you can always get some at the store- pick up a nice big bag, make salad and this yummy healthy Spinach-Rice Casserole.

3) Heat the butter/oil, in a deep skillet. Add onion and sauté 5-8 minutes~until soft. Add spinach, salt, and garlic and cook about 5minutes.more over medium heat, stirring frequently. Add this to the rice, along with the seasonings and half the sunflower seeds. Mix well.
4) Beat together the eggs and milk, and stir this into the spinach-rice mixture, along with the grated cheese.
5) Spread into prepared pan, sprinkle with remaining sunflower seeds and dust with paprika. Bake uncovered for 35-40 minutes- until heated through and lightly browned on top.
Enjoy! (freezes well too!)
