Re: Umbrellar Pine , gone poorly

Hi, If you can, have a look at the tips of the shoots/branches with a hand lens and see if you can see Aphids! (greenfly) they could be green or black and located up the stem next to where the needle grows out of the stem.
There is no control the tree is too big to spray, Best thing to do is to take each plant out and look at it as an opportunity to plant something else, make sure you prepare the soil well with manure or garden compost or compost from your local council recycling plant.
Hope this is helpful
John.
