Kinds Of Stems

Gretchen Voyle: Pollution at home is pollen

Q: I have something odd that is happening outside my house. My deck and furniture on the deck are covered by a fine layer of yellow dust. It is everywhere. When I try to wipe it up, it smears. When I attempted to smell it, I just started sneezing. It's even in my pine trees around my deck. I shook a branch, and it was covered by this yellow dust that floated down. Is this industrial pollution or are my neighbors spraying some terrible chemicals again?

A: The source of your contamination is much closer to home.

Actually, it's surrounding your deck.

In the spring, large pines produce pollen cones. These are on the branches, right behind the new growth. They resemble little buttons or balls.There are no needles in this area.

Out of these pollen cones comes pollen.

If everything goes the way it should, pine cones will be produced later in the summer.

For pines, especially white pines, this pollen can look as yellow as sulfur dust. This spring, with its abundant rain, caused many plants to jump into overdrive in the growth department. For evergreens, large numbers of pollen cones — and later, woody pine or spruce cones — can be produced in response to the excesses.

A drought the year before can also stimulate this activity. A great deal of rain and ideal temperatures can cause this to happen in the spring when pollen cones are produced.

If you lived in many Southern states, where loblolly pines grow, the pollen can be so heavy in the air that it looks like fog or smoke.

Needless to say, many people who have allergies are greatly irritated by the pounds of pollen landing in their eyes or going up their noses.

If you are sneezing, you now know why. Be patient; the pollen storm will soon be at its end, if it hasn't already.

It's just nature doing natural things.

Q: Are plant stems having some kind of a problem? In my yard, there are dozens of different kinds of plants that have what looks like a mass of foamy bubbles around the stems in places. There is some in my Scotch pine tree, and there are bubbles on weeds. It was icky, but I tried to knock the bubbles off, and I think they are coming out of the stem. Why are the stems oozing?

A: The stems aren't oozing; they are getting sucked.

Your tiny suckers are called spittle bugs. In some places, they are known by the quaint name of froghoppers, and the frothy liquid they dispense is called frog spit, cuckoo spit or snake spit.
