O’Neil’s would be happy to go over your choice of replacements with an arborist viewpoint on the pros and cons of each species. We can purchase, transport, plant, inoculate and fertilize as needed at a fair and reasonable cost, which would be in addition to the original estimate. After transplanting, trees need attention to ensure they make it. Unless we were separately and specifically contracted to nurture the trees through the first few months, it would be up to the customer to do the correct amount of water to ensure their survival.
