Soil pH- What’s It All About

            Soil pH is an indicator of the relative abundance of hydrogen (H⁺) ions and hydroxyl (OHˉ) ions in garden soils (Table 1).  These ions play a very important part of soil fertility and a plant’s ability to absorb nutrients from the soil. The pH scale runs from 1 (highest acidity) to 14 […]

Winterberry Holly Brightens Winter Scene

            To escape from dreary days this winter, brightened up your landscape with deciduous hollies. Among a long, long list of deciduous holly species, winterberry holly (Ilex verticillata) is the superior choice (USDA hardiness zones 3-9). Inconspicuous white blooms in spring are followed by red, orange, or yellow berries in fall. Compared to their evergreen […]

My Search Continues For A Hardy Gardenia

                The longer you garden, many plant species keep improving, including their winter hardiness. A few years ago, growing gardenias (Gardenia jasminoides) in a U.S. zone 6 garden was a dream. Today, hardy gardenias are a safe bet in zone 7 or in zone 6 in a protected area of […]
