Lack of sea or tree disease/blight? After moving to a new home just this minute, we pruned...

After moving to a new home just this minute, we pruned a mature, overgrown evergreen (two weeks ago) around the foundation. The tree is now yellowing contained by many spots. A minor concern is that this tree is touching a line of windscreen shrub/trees that are adjectives dead or dying due to any blight or lack of watering by the previous owners. (Those trees are shot through near a rusty discoloration -- again, lack of river or something worse.)

What could be causing the instant yellowing of this one, previously healthy tree we'd hoped to salvage? (Photos available for emailing.)

Any advice would be appreciated! Thanks!
Answers:    I would guess that the previous owners, probably didn't bother to dampen because they were disappearing and dryness has cause stress. Once trees or shrubs are stressed they are subject to attack by bugs or disease.

Unless you completely took the bark from right round the tree (ringbarked) the tree, the tree shouldn't verbs about the lower branch removal.

I would river the plants deeply to get hold of them going again. Buy some Seasol or other sea weed extract (from garden centres), and hose all the sickly plants this is a tonic and a reviver and is marvelous. Do not fertilize at this stage the shock could eliminate the poor things.

Scratch some bark from the windbreak shrubs stem. Is it green underneath, (plant is still alive). If the shrubs are feebly diseased or dry they may loose all their leaves as a survival technique. If the stems are still green the plant will reproduce foliage near some TLC, and a prune if they have some die backbone.

Time and care are the solitary solutions at this stage. Wait and see what you are working with it may not be as desperate as you think.
yeah could do that after adjectives it back. Stress can do a plant to do this if it is harshly hack back
