How cold did it get overnight? Perhaps you should check out your rhododendrons outside. The leaves of some rhododendron species (Rhododendron spp.) and Redneck Rhody (Daphniphyllum macropodum) droop down and/or curl up during really cold nights. Plant scientists believe that this reaction may be a plant’s way of reducing water loss through stomata cells on […]

No Comments »Three Native Azaleas That Should Be Included In Mid- Atlantic and Southern Gardens
Posted by Hugh on March 25th, 2024
About Native Azaleas: Flowers appear from April to September depending on species. Flower clusters (called “trusses”) appear just before the leaves emerge. Each truss may bear 3 – 12 blooms, which open 1.5 – 2 inches wide. Flower colors vary among native species from white, pink, orange and red shades. In many spring blooming species, the open petals […]

Posted by Hugh on October 12th, 2023
An unusual swelling on trunks of trees and occasionally on large branches are “burls”. They’re round, swollen-looking growths on tree trunks and large scaffold branches. Should or shouldn’t you be concerned? Burls are not uncommon and can be found on cherry, maple, oak, buckeye, ash, willow, locust and walnut in Eastern forests. Root burls may […]

Posted by Hugh on February 7th, 2023
The late winter / early spring period are ideal times for pruning many (not all) flowering shrubs. At this time, shrubs are leafless, and you are better able to see the overall shape of the shrub and easily identify dead, damaged, diseased wood, and structural defects. Pruning also stimulates new growth. Spring flowering shrubs (those […]

Containers filled with shrubs and perennials, doesn’t necessarily ensure their winter survival. Without adequate cold protection plants may succumb to cold injury—turning them into dead annuals. To over-winter perennials in containers, you need to know their root and shoot temperature hardiness. Often, plant hardiness ratings is listed on the label. Roots and shoots of several […]

In early spring many area gardeners rush to set out hummingbird feeders filled with a sugary solution to encourage these feathery critters to visit. However, the sugary drink also attracts ants, bees, and wasps. The solution does not furnish vitamins, minerals, and carotenoids that hummingbirds pick up from pollinating flowers and eating insects. In addition, […]

“A healthy plant in the right place with proper maintenance” is a rhododendron that has few problems. Rhododendrons and azaleas are acid loving plants meaning plants should be planted in humus-rich slightly acidic soil (pH 5.2 -6.5). If the soil is not well amended, rhododendrons will have trouble surviving long term. Once planted, water during […]
