$3K to arriate the soil around all the trees with a with a high pressure air jet 12” down in the soil...apparently something they invented. Three treatments @ $560 ea. to spray everything for insects and mites. $600 for soil samples and fertilization. And $1300 for rigging cables to limit branch movement on the giant cherry tree. I might just cut it down.
Aerate the roots at 12” with high pressure air... they should also be adding Triple Super Phosphate (0-44-0) wettable powder into liquid, for root growth and strength. Aeration is always good, but while they’re down there, might as well feed the root system with TSP.
Cost to spray is okay, based upon all the plants I saw in the pics.
If the cherry has cracks in branch crotches, bark leaking sap, round borer-like holes on main trunk, and is old, just remove it and consider a nice large B&B Stewartia pseudocamellia, or a 10-12ft B&B ‘Red Rocket’,’Firecracker’,’Dynamite’ Crape Myrtle. Keep it to 5-6 stems, limbed-up of twigs and branches to 5-6ft and it’ll be a specimen showpiece.
Stewartia pseudocamellia:
White summer flowers, magnificent red fall color and spotted cinnamon bark during winter months:

‘Red Rocket’,’Firecracker’,’Dynamite’ variety:
Here’s a 10-12 B&B (balled & burlapped) ‘Red Rocket” CM from one of my suppliers, Worthington Farms. Limbed-up and ready to be dug and installed.
