White Pine Issue

Hello All,
I have 6 white pines on a moderate slope along my property. These trees were present when I bought the property so I assume they have been there for 5+ years. The only issue I have seen in the past 2 was what I assume a pine weevil issue early this fall. I trimmed off the effected branches and the trees appeared fine. This week each of the trees started turning yellow apparently from the inside out? The green needles seem healthy and well attached, the yellow come off very easily. Hoping this is just some type of fall dropping but it seems pretty severe as you can see from the attached. Any thoughts? |

| White pines shed their needles when they (the needles) reach around 3 or 4 years old. This is perfectly natural, the first wind that comes will blow down the yellow needles. Usually they change in October, but given the drought this year, they are casting their needles early. Our white pines here are changing right now; if you aren't used to white pine, this may be a bit disconcerting, but it is perfectly normal. This is why you see the fallen needles so deep under a white pine. |

| Normal need shed in the fall. Most P. strobus I've seen actually shed their needles in the fall of the second year. |

| good news. Thanks for the quick responses everyone. One last question, is there any maintenance, fertilization, etc I should consider performing? Anything I can do to reduce the likelihood of pine weevil issues next year? Thanks! |

| Whoops! Sorry, that's right - P. Strobus is a second-year needle drop. It's the spruces and firs that last up to 4 years. |

| rj, just the usual; Don't allow things to get too dry. That's #1. After that, there's little of real value to be done. White pine, like most trees, are mostly able to grow on their own without any heroic efforts on our parts. Just water the whole area next year if it's dry. Aim for the equivalent of about one inch of rain/week. And if rainfall is "normal", whatever that word means anymore, even this watering should not be needed. +oM |
