Okay, let’s tackle this. So John has 24 years of experience in horticulture, which is a significant amount. His expertise spans multiple areas like landscape design, landscaping, irrigation, and sustainable practices. He’s the owner of Twining Gardens, which suggests he’s self-employed and has some control over his rates. Location is Newtown Grant, Pennsylvania, which is a moderate-cost area. Considering his extensive experience and skills, I would estimate his hourly rate to be around $125. This is slightly lower than what I would expect for someone with his level of experience in a larger city, but still reflects his expertise and the regional cost of living.
