We thought an arborist would recommend the best tree for my pool area. Mike recommended pulling gout our citrus trees and replacing them with sisoo trees. After spending more than $2000 for these beauties, we have had nothing but problems. EVERYONE, including other arborists, landscape companies, my pool guy and gardener were shocked we put them in They have invasive root systems, and are a total mess. After three years dealing with this, we are done! We will now have to have them removed, stump grinder and replaced ( ironically with citrus again). A HUGE...UNEEDED expense. This company is terrible! Only use them if you have endless money to throw away!
