Some people keep the mulch from their tree work to use on their gardens. If we have been paid to do a customer’s tree work, we believe the mulch should be theirs for free. Amazingly, some tree companies charge the customer for keeping their own mulch! We also have a register of people who want to buy mulch from us when we have some, as it’s much cheaper than from a landscape supplier. We have 5 mulchers (also known as woodchippers). These machines can mulch timber up to 20 inches wide.
