Under Or Over-Watering
- Under and over-watering causes pear trees to lose their leaves quickly. Typically, under-watering symptomsinclude leaves curling, drying, and browning before they fall off. On the other hand, over-watering symptomsare dropping green leaves and swampy-smelling soil. Over time, this leads to root rot, a water mold, which decays the roots and can kill the pear tree. So, what’s the best way …
Extreme Weather
- Generally, pear trees can handle temperatures between -30ºF and 90ºF but get stressed when there’s an early frost, extreme heat, or a swing in weather. This stress causes the tree’s leaves, blossoms, and fruit to brown and drop. To prevent this, monitor swings in weather and shelter the tree if possible. For best results, keep your pear trees between 45ºF and 80ºF during the spring a…
