Christmas tree questions

Q.     Are fake Christmas Trees fireproof?

No, they’re not. They catch on fire every year. According to a report from the National Fire Protection Association, 28% of home fires involving a Christmas Tree were from a fake tree.

Q.    Do Christmas Trees trigger allergies?

No, generally they do not. There have been some concerns about outgassing coming off the fake trees plastic compounds and heavy metals embedded in the plastics rubbing off on your hands, but there is not much proof to cause a serious amount of worry.

Live trees may have some residual pollen and dust on the needles. This can be remedied by hosing off the tree prior to bringing it into your home.


Gigantic bulb and bloom

Now is the time to plant and grow these great long-lived bulb the Allium giganticum. It blooms in June, producing a gigantic sphere of a flower that is up to six inches a across. It looks like a large geodesic dome. (more…)

Drop the clippings

Turf experts all agree, if you regularly mow your lawn, you should let your clippings drop back to the ground. Because clippings are 90% water they readily break down into organic matter that feeds the soil and improves soil texture.

In dropping your clippings you are also reducing the need for lawn fertilizer. Therefore you can reduce the total amount of fertilization by 25% because the decomposing grass clippings break down and add fertility to the lawn. Over time you will notice that your lawn has better water holding capacity and a general increase the overall health of the lawn.

Of course, you should only drop clippings when you mow regularly and don’t remove any more than 1/3 of the total length of the blade when you mow. If it is longer than 1/3 and the mowing interval has been more than a week, then it would be a good idea to pick up your clippings.

One of the easiest ways to preserve it is to grate it and place in a freezer bag and freeze it. Then it is ready to add to most any appropriate recipe. Zucchini can also be sliced thin and dehydrated in a food dryer. Zucchini can be pickled and canned, or even made into a relish.

For fresh eating try thin slices with a bit of olive oil on the grill!

Mowing tips

Clover as a lawn

In the 1950s and 60s clover was sold in your turf mixture because the clover has the ability to make nitrogen fertilizer out of the air in the soil and thus provide free fertilization to the turf.

Along came broad-leaf pesticides like 2-4,D or “Weed-B-Gone” ® that would selectively kill all broad-leaf weeds like dandelions without hurting your turf. These pesticides also killed the clovers.

Over time, people have decided that a lawn solely made up of grass is preferred and now actively spray every time they see another broad-leaf plant sprout up in the turf.

Now clover is making a comeback as people are starting to shun pesticides and fertilizer. One such clover is being sold as a replacement for lawns is known as “ Miniclover®” (Trifolium repens). It is a proprietary dwarf perennial clover bred to reach only four inches high. It can be a lawn alternative or mixed into your current lawn grass. Clover’s relationship with root microbes enable it to make its own nitrogen. Thus, if you add it to an existing lawn you will need less fertilizer. You can also create a pure clover lawn. For seed sources search the internet for “miniclover.”

Why clover?
* It improves the soil by fixing or making nitrogen from the air in the soil
* It sends down deep roots for drought-tolerance
* It grows fast
* It is environmentally friendly
* It grows in part shade and sun
* It withstands foot traffic
* If you plant only clover and eliminate all grass, you don’t have to mow
The Downside?
* It flowers, so you’ll see little white flowers in your lawn that some may think is unsightly
* The flowers may attract bees and if you step on a flower you might get stung
* There is no broad-brush chemical way to eliminate other weeds like there is with broad-leaf weed killers used in grass

Russian connections

Russian Sage, From you are looking for a large, beautiful, trouble-free perennial, consider growing “Russian Sage.” It is also known as ‘Perovskia’ named after a Russian governor. It has aromatic leaves and lavender blue flowers that bloom from mid-summer until frost.

It is shrub-like, reaching up to 5 feet. In spring, prune it to six inches and it will fully grow back in summer. Russian sage prefers full sun.

Pruning precautions

IMG_0945With the warmer days of spring, avoid the temptation to prune spring flowering shrubs such as lilac, forsythia, and spirea. Pruning before these plants bloom prevents any show of flowers later this spring and early summer.

Instead, wait to prune until the week after their flowers have faded later in spring. Be patient on these plants and focus on pruning other non-spring blooming trees and shrubs.

Growing Coleus

Coleus are plants that are solely grown for their colorful, showy leaves. Leaf colors include red,coleus orange, yellow, bronze and mixtures of colors in interesting patterns. The leaves are as bright as any flower. They grow outside in the summer and indoors as a houseplant. Pinch them to create a bushier plant. To make more plants, place a cut stem in water and it grows roots.

There are many different Coleus varieties to suit your space. You can find  low-growing, trailing types; midsize selections; and tall plants that can reach a few feet in height. Some coleus cannot take full sun while others have been bred to tolerate sun. The only way to tell is to look at the catalog description or plant tag. If it says it can take full sun, then it probably will. If not, don’t do try it as it will burn the leaves.

If you have a coleus and want more plants simply place a cut piece of stem with a few leaves on the upper stalk in a glass of water and it will soon grow roots into the water. After it produces a number of roots you can then pot it up into soil.

The Coleus is a close relative to mint but without the minty fragrance. You can tell the relationship by noting that both mints and coleus have very distinctive square stems.

Gravel in the bottom of your pot?

img_0419Do you put gravel in the bottom of your houseplant pots to improve drainage? Studies show this doesn’t help drainage and takes away from the space needed for root growth. The most important thing every potted plant needs for drainage is a hole in the pot’s bottom. A small piece of window screen placed over the hole prevents soil from coming out. Also, regularly empty standing water from the saucer.
