This practice, also called “topping”, reduces tree (or shrub) height. Over 25 years, Southern Living magazine called this “crape murder”. Crape murder is not going away. More crape […]

Larches (Larix spp.) are majestic deciduous conifers in their northern ranges of their habitat (USDA hardiness zone 4 to 7). However, trees do not prosper in hot and humid summers south of USDA Zone 7. One of the best is Japanese larch (Larix kaempferi), but unfortunately, it is not commonly planted in U.S. landscapes.
