Q. Larch tree shedding needles

My zip code is 18032, and the larch tree does not shed needles until the fall. It is June and they are turning brown and falling all over the patio.

If you have been experiencing extremes in temperatures, such as much warmer weather, then the tree could be stressed, which would make it go into dormancy early to survive. Other than keeping it well watered, there is little else you can do but it should recover on its own. Another possibility could be insects (which would most likely affect the area nearest the crown) or some type of fungus.

Q. do larch trees grow from the “cone”

If I remove the little portions that make up the cone and place them beneath soil, will those portions grow?

You will need to propagate from harvested seeds.

Here is a link with more specifications on the process.

Q. How can I grow Larch trees from seed?

My husband died in 2010 and I have just found a match box with writing on it saying that the seeds inside are Larch seeds.

Q. larch tree

I am concerned that our 10 year old larch has no greening as of today(May 12,2017).When I scrapped the bark to see if it was green underneath it is.I am wondering if this rainy colder spring had delayed the growth.Other larches I have seen have their new needles.

Certainly weather conditions, ground temperatures and moisture levels can cause delays in trees greening and leafing out.

Our other trees in the area growing yet? Have you check soil moisture?
Do the branches bend or snap off? If the branches snap they are not alive.
A tree can die off for sometimes unknown reasons.

Q. Browning of larch needles in summer

I have two coniferous larch trees that the needles are turning brown and falling off, even though they have healthy new growth on each branch. I cannot figure out why as I have two very close neighbors whose larch trees look great. I planted these trees about four yrs ago.

Sorry no photos!

There can be a few reasons for browning of Larch Tree needles; from pests to a few diseases.
It may take further inspections to determine the issue.
These links may help with diagnosis.
