|We purchased 6 dwarf mugo pines a couple of months ago. All of them are doing fine except for one. The one mugo pine is browning on the top, almost like it is burning. The needles and the branch is turning brown. The mugos are watered from a drip system so I do not think it is from water on the needles in the sun. We have a clay soil and planted the mugo in a the clay mixed with sand and compost. We were told that it could be too much water, but according to a moisture meter, this is within the correct range. could it be not enough? I have a picture, but I do not see a place to attach the picture or sent it to you....but I will check again...
Your help is greatly appreciated!!
|If all of your plants are receiving the same amount of water and sunshine, I don't think the cause is from that. However, the site with the ailing Mugo may not be draining as quickly as the other sites. Why not dig down 3-4" and see how wet or dry the soil is and then compare it to the soil around the healthy plants.
Aside from soil drainage, your mugo may just need to adjust to it's new home.
Best wishes with your garden.
