A Bit about Bulbs    

Night temperatures are cool, the air is almost crisp. The vegetable harvest is tapering off and green foliage is starting to change to beautiful shades of red and yellow. There are many signs that tell us that fall is here. But this year, instead of dreading a long, cold winter, why not make the most of this glorious season? Gardening is not finished—for that matter, it never is! There is always something to do, and right now is the time to plant spring-flowering bulbs.

Dividing Perennials    

Q. Can I divide perennials in the fall?

A. Late summer or early fall, when the worst of summer’s heat is over, is a great time to divide perennials. Because there are so many gardening tasks in the spring, it also helps to spread your workload.  Perennials need to be divided when they develop small or sparse foliage or bare spots in the middle. These signs are a good indicator that there is too much competition for water, nutrients and space.

Fall divisions will have plenty of time to develop new roots as long as you allow 6 to 8 weeks before the ground freezes.  Iris, peonies, poppies and moss pinks even do better when divided in early fall.  The only poor choice of a time to lift and divide perennials is in August, a hot month with little rain. If possible, lift and divide perennials when they are not in bud or bloom.

Choose a cool, cloudy day to divide perennials and try to water a day ahead. If dividing in the fall, cut the foliage back to 6 to 8 inches. Use a shovel to dig under all 4 sides of the plant about 3 inches out from the edge of the plant.  Lift out the clump to be divided, shake off the loose soil and remove any dead leaves or stems. Clumps with fibrous roots can be pulled apart by hand or with spading forks. Plants with tough, dense, roots (like hosta or daylily) may need to be cut apart with a knife or sharp spade. Discard the old centers of the plants as well as any soft, rotted roots. Re-plant your divisions immediately, water them well, and keep them moist for several weeks.

Guidelines for Using Animal Manures & Manure-Based Composts in the Garden    

Animal manures and animal manure-based composts are rich in plant nutrients such as Nitrogen (N), Phosphorous (P) and Potassium (K) and provide organic matter that conditions the soil, so they make excellent soil amendments for the home gardener. However, it is important to use them effectively and safely.

October’s the Time to Dig and Store Summer Bulbs    

The difference between hardy and tender bulbous plants is a matter of geography, not underground structure. Plants originally developed bulbs, corms, and tubers to help them survive conditions like cold and drought. In cold-climate gardens many tender bulbous plants which can’t survive extremely low soil temperatures can be lifted and brought indoors for their winter’s rest. Some of the varieties commonly lifted and stored indoors inNew Englandare tuberous begonias, dahlias, cannas, caladium, elephant’s ears and gladiolus.

Sprucing up Your Home with Holiday Greens    

Decorating our homes with greenery for the winter holidays is a ritual that dates back many centuries. Among the greens that are important this season we find evergreens, like balsam, spruce and fir, as well as holly, mistletoe, ivy, laurel and rosemary. All have great significance attached to them and most of it predates Christianity. For thousands of years, evergreens have represented signs of hope and life. Not only do they remain green when everything else in nature appears dead, some of the plants actually bear fruit.

Understanding Your Soil Test Results    

The soil testing lab takes your soil sample and runs a small portion of the sample through a series of sophisticated test equipment. The results provide a chemical inventory of the soil – clues as to the quantity of nutrients or elements in the soil and their availability for plant growth.

Vegetable Garden Cleanup    

Cleaning up your vegetable garden will help to reduce next year's disease and insect problems. In fact, good sanitation is one of the most important steps you can take to insure that next year's garden will be healthy.

Plant disease agents such as bacteria, fungi and viruses all remain alive, though dormant, during the winter months. By recognizing the places where these organisms hide, gardeners can often destroy them and prevent disease outbreaks the following spring. Many fungi spend the winter on or in old leaves, fruit and other garden refuse. These fungi often form spores or other reproductive structures that remain alive even after the host plant has died. Cucumber and squash vines, cabbages, and the dried remains of tomato and bean plants are all likely to harbor fungi if left in the garden over the winter.

Insects, too, survive quite nicely over the winter months. Cucumber beetle, Colorado potato beetle and Mexican bean beetle all overwinter as adults. In spring they migrate to young plants where they feed and lay eggs for a new generation. Insects and plant pathogens survive on weeds as well as on garden plants. Many weeds serve as alternate hosts for insects and fungi, helping them to complete their life cycle. Destruction of these weeds removes a source of future troubles.

To avoid any or all of the above problems, infested plant debris should be carefully raked up and disposed of in the trash. Do not put refuse on your compost pile. It takes a fair amount of heat to kill these organisms, and you won't want to recycle them right back into the garden.

Blueberry Stem Borer    

Blueberry stem borer is a beetle also known as the rhododendron stem borer and the azalea stem borer. It is in the family Cerambycidae [long-horned borers] and has a two to three year life cycle.

Mosquito Bites    

What safe methods do you suggest for protecting my family from mosquito bites?

Seasonal Invaders    

Q. Is there something I can spray to get rid of the brown bugs that keep coming indoors?

A. The bug you’re referring to is probably the western conifer seed bug. It’s one of five seasonal insects that commonly invade NH homes in the fall. The others are ladybugs, boxelder bugs, cluster flies, and the newest arrival, the brown marmorated stink bug. These invaders enter through cracks and crevices around doors and windows, ventilation louvers, air conditioner vents, and chimneys and fireplaces. The best way to keep them out is to do some serious caulking and sealing before they begin to congregate on sunny days in the fall. If you have an air conditioner, cover the opening or remove it from the window.

Western conifer seed bug feeds on the developing seeds and flowers of conifers, especially pines, white spruce and hemlock.  They are easily identified by their large size, about ¾ of an inch, and the flattened leaf-like expansion on their back legs. If you crush them, they will stink, although they’re not a stinkbug.

None of the winter invaders will harm you or the contents of your home.  They simply want to get out of the cold and will often spend the winter inside the walls of your house. Spraying a pesticide isn’t the best solution since this exposes everyone in the house to the toxins in the spray.  A vacuum cleaner is very effective, or you can sweep them up and put them back outside. Or, as Dr. Alan Eaton, UNH Cooperative Extension entomologist says, “learn to love them”.

Squash Vine Borer - Managing Problems    

Usually the insect bores through the vines, but occasionally they bore into the fruit of hard squash or pumpkin. Fruit damage generally occurs when there is a late flush of moths.

Spiders    
Springtails    
Winter Tick    

Winter tick is the only species of one-host tick in New Hampshire. Unlike other hard ticks, which feed on two or more hosts in their lives, it remains on a single host. Moose are the most common and severely impacted host for winter tick.


Insect Pests of Plants

Aphids    
Aphids, or plant lice, feed on most vegetable crops, many houseplants and many ornamentals grown in New Hampshire, as well as numerous weeds and wild plants. With their awesome reproductive abilities aphids can build up in large numbers in a very short period of time.
Cabbage Maggot    
Colorado Potato Beetle    

The Colorado Potato Beetle (CPB) became a pest when settlers brought potatoes into the Rocky Mountain area, the native home of this beetle. The beetle preferred the potato to its host weed and has spread to become a serious pest throughout the US and Eastern Canada.The CPB feeds on the leaves and terminal growth of nightshade-family plants, such as potato, tomato, and eggplant. The potato, however, is its preferred plant. The above-ground destruction of potato plants can cause severe reduction in tuber size and overall yield.

Cutworms    
Cutworms are the larval form of dozens of different species of small brown or tan, banded moths. Depending on the species, cutworms damage plants in several ways.
European Corn Borer    
The European corn borer (ECB, family Pyralidae, order Lepidoptera) arrived in North America during the early 1900s, probably in broom corn imported from Hungary and Italy for the manufacture of brooms.

Striped Cucumber Beetle    
The Striped Cucumber Beetle (CB), Acalymma vittata (Fab.), is one of the most devastating pests of cucurbits (cucumbers, summer and winter squashes, all types of melons and pumpkins) east of the Rocky Mountains. Both adults and larvae feed on cucurbit crops. This insect is also responsible for the spread of plant diseases such as bacterial wilt and cucumber mosaic.
Tarnished Plant Bug    
Among the several species of plant bugs that invade New Hampshire fruit, vegetable and ornamental crops, the one that does the most damage is the tarnished plant bug (TPB), Lygus lineolaris.

Northern Catalpa, Catalpa speciosa    

This curious tree with its almost tropical show of speckled white flowers, looks out of place in  New England;  too showy for out Puritan tastes.  The elegant trumpet shaped flowers are clustered on panicles (stems) in tiers with three smaller stems. The first two tiers produce three flowers at the end of these smaller stems to add up to nine individual flowers per tier or 18 flowers on the two tiers.  The lower tiers have but one flower at the end of the smaller stem or six additional flowers.  There were 24 individual flowers on the cluster that I counted.  Somehow the seeds produced by the flowers end up inside long skinny 6” -12 “ beans that dangle from the tree later in the summer; hanging on through the winter.
