The Bay Gardener by Dr. Francis Gouin

Not all Christmas trees are equal

Not all evergreen trees are equally fire-resistant. The Douglas fir is the most fire-resistant tree, while the popular Fraser fir is the most combustible. Freshness has nothing to do with this comparison. Douglas fir is a low-resin tree, while Fraser fir is a high-resin tree. As the tree dries, the resin becomes highly combustible.

Give a little, get a lot

The vegetable gardening season does not end with the first killing frost. Tomatoes, peppers, eggplants, sweet corn, snap beans and lettuce may have been killed by the first frost. But if you are an avid gardener, kale, collards, peas, cabbage, broccoli, cauliflower, spinach and Brussels sprouts should still be growing.

Dig deep for tulips, daffodils, hyacinths and other bulbs

If you want big flowers and more flowers from your bulbs next spring, plant them now. If you wait until the ground starts to freeze, you’ll see smaller flowers and short stems.

Three steps to keep them happy indoors

Some houseplants have to be repotted every six months, while others can stay put for two or three years. Frequency of repotting also depends on container size, quality of care, productivity of the rooting medium and frequency of nutrient applications. Annuals — such as grape ivy, begonias and marigolds — have very vigorous habits of growth and should be repotted at least twice yearly. Foliage plants such as ficus, schefflera and crotons tend to grow slowly and can be left alone for a year or two, depending on the age of the plant and container size.

Just a little care will do it

This summer, I harvested my biggest crop of garlic ever, with my elephant garlic the size of a baseball. I attribute my success to incorporating an inch-thick layer of compost just before planting, mulching the garlic with Maine Lobster Compost just before the ground froze and giving the garlic plenty of room to grow. I planted elephant garlic in a six-by-six-inch spacing and the Italian garlic in a four-by-six-inch spacing. Come summer, I stopped hoeing the weeds as soon as the foliage was sufficiently dense to shade the ground.

Water now or expect poor fall color — and a killing winter

This year’s dry late summer and early fall will put a damper on foliage colors. Don’t expect a long, lingering colorful fall. Many trees are already dropping their leaves due to the drought conditions we are experiencing. There is even premature coloration in the foliage of red maple, dogwoods and sweet gum.

Fall’s the time to get to work

Warm days and cool nights, combined with shorter daylight hours, are what the doctor ordered for the favorite grasses of Chesapeake Country: bluegrass and fescues. They’re called cool-season grasses because they germinate, produce roots and lap up nutrients once summer’s heat shuts down. So now’s the time to get to work on next year’s perfect lawn. Test Your Soil     A good lawn grows from well-prepared soil.

A short lesson on the difference between aerobic and anaerobic decay

A Bay Weekly reader cornered me at Christopher’s in West River, complaining that her compost pile stinks. She was composting in a rotating drum on an elevated stand. Her complaint: the contents in the drum were slopping wet and the odors so strong that her neighbors were complaining.     She admitted that she had not read the directions on the drum. “What difference would that have made?” she wanted to know.

You’ll enjoy the best flavor and pound out your aggression

The best sauerkraut is made from freshly harvested cabbage grown during the fall months. I make about 20 pounds of sauerkraut every two to three years and store it in canning jars.     Choose cabbages that form tight dense heads and can be uniformly shredded into pieces approximately one-eighth of an inch thin. I prefer Flat Head Dutch be­cause the tight, dense heads can easily be shredded. Heads can weigh five pounds or more.

Composting is a science nature has been using since the earth was created. It has only been in the last five decades that we have begun to understand what it does and how. I remain constantly amazed that such a simple process can be so complex. Understanding the pro­cess is the key to producing a quality compost that will benefit the soil in your garden in numerous ways.
