Pests can do a real number on your precious tree's health. Some destroying your tree's beautiful aesthetic and others bringing fatal disease with them. Your Sims Arborist will create a treatment plan specific to your tree to help keep it in the best shape to fight off these pesky creatures. 

More Info Coming Soon!

Working alongside Mother Nature, we utilize her best natural line of defence against pest & disease. Customized treatment plans can include beneficial insects (i.e. Lady Beetles & Lacewings), beneficial fungus, soaps, horticultural oils, & soil biologicals. 

More Info Coming Soon!

We all love the beauty the trees bring to our lives, but we may not have that same love with their messy fruit. We offer a variety of treatment options to limit the growth of fruit on trees. 

More Info Coming Soon!

82% of California is currently experiencing severe drought. Treatments help increase the tree's water retention, helping to reduce its need for water & your water bill. During times of water reduction mandates, treatments can also keep you in compliance. 

More Info Coming Soon!

Need a deeper dive into the health & safety of your tree? Or perhaps you need to know how to protect your tree during contruction? We've got you covered. Sims offers a variety of different types of reports to include the information that is important to you.
