Giving a bid to remove two mature pyracanthas from a customer's property. I've trimmed them for years so working with the thorns is nothing new to me but I've never removed one. Just wondering how the root system is. Are there thorns on the roots? Are the roots soft and easy to cut with a shovel or are they hard needing more persuasive means? How large of a root ball can I expect? Plants are mature, maintained in last couple years to a 8 foot wide by 6 foot tall size but were closer to 12 by 12 when I first started maintaining property. I'm not needing to remove all the roots just the root ball. I cannot gain access to bushes with machinery or chain/truck/mower. All by hand! Thanks for any painful/stabbing insight.
