mugo pines deteriation
Comments (19)I'm quite sure I was wrong last September in thinking that I had solved the mystery of my mugo pines deteriation by fertilizing and using a disease control spray.What I learned this year was that I was looking in the wrong place for any insects.I was looking at the branches that had already been devoured by the sawfly larvae. This year, thanks to the forum help I got,I found them little suckers on the good, healthy needles devouring away. I went to Google as recommended and was able to find an insecticide at Wal-Mart called Bug Killer Concentrate Sevin by Eliminator (a Gro Tec company) and sprayed the pines,both those that had already been devoured (3 of 9),2 that were partially hit and the remaining 4 that were in good shape.I know now that you have to pay attention (inspect) the pines a lot sooner than late May when a lot of the damage is already done. I suggest start looking in early April so you can take corrective action sooner. I'm not totally sure if spraying with the insecticide is the only corrective action to take but it is the only one that I know of that works because when I inspected the pines after a few days there was no sign of the critters on the pines but there sure were a lot of dead ones lying on the ground adjacent to the trees. If anyone knows of another spray to use beforehand, like a powder,before the sawflies emerge, I would be forever grateful....See MoreMugo pines dying
Comments (2)Hi karen64, It's definitely not bag worms, yuck. We had some on a redbud last year and the webs are nasty. I sprayed them with some detergent in water and they quickly died. In the spring we've had brown worms on the new candles on a couple of mugo pines and I used the same detergent water solution to kill them. After spraying with the sulfur no other affected pine has died and seems to be ok although I still see the white covering on the base of the new growth. I wonder if it may be sap the tree produced to protect itself?...See MoreHelp with quickly browning of mugo pines
Comments (19)Promised to touch back. Somewhat depressing morning walking around the property diagnosing issues all of which appear to be "plumbing" related. Too much rain has contributed to drowning and needlecast, and has exasperated other deficiencies. Species experiencing needlecast are not always the normal suspects and why it is so widespread in recent years along the mid-Atlantic is unknown. He could not tell why the mugos died specifically, but he said they are definitely dead. What is green on them is dry like a Christmas tree's needles. Serbian spruce and other spruce types are being badly hit with needlecast. Evergreen species that are usually disease free and hardy are suffering from needlecast all over the greater Baltimore area. Based on the conversation, there maybe a chance to save three out of five Serbian spruce. These were sprayed three times last year but removal of two will provide more circulation for the remaining three. These trees are at least 30 feet tall and a key focal point of our landscape. All three 20 foot boulevard cypress are probably too far gone to try to save. They showed little signs of trouble last season, but they have dropped so many needles now that you can see through them. Dragonlady holly most likely drowned or received so much water that key nutriates were washed away or the plant was unable to access them. We await a full report and recommendations. Depressing....See Moredrought tolerant companions for dwarf mugo pines?
Comments (12)If you like hedges, these roses, shaped, could make partially leftover ivy look soft and 'trailing' in contrast....
