During the hot summer months, all plants are shipped in full leaf and active growth. While we take great care in packing, transit heat and confinement can cause temporary shipping shock such as minor leaf wilt or yellowing. This is normal and recovery begins once plants are watered and acclimated after arrival. For best results, unpack immediately upon delivery and keep plants well-watered in a shaded area for several days before planting. We highly recommend buying 2nd day air service for all Quart size plants and trees, so they will arrive faster during the heat of summer.
