Celebrate the Winter Solstice by Honoring Our Earth

The Shortest Day of the Year On Saturday, December 21, 2024, indigenous people and others who practice nature based spiritual paths celebrate the Winter Solstice.  Winter Solstice has been observed as a holy day for millennia, since before humans kept records, because it marks the shortest day of the year and the return of the sun to warm the Earth for the growing season ahead.  Historians have found that ancient stone circles, pyramids, and other prehistoric stone constructions are oriented...

The Annual Pruning Clinic

  Woody plants remain healthier, more productive and more beautiful with strategic, well-timed pruning.  Pruning young plants guides their growth into a strong and balanced structure.  Pruning older plants opens them up to sunlight and airflow, limiting the opportunities for disease to infect them.  Proper pruning can also rejuvenate them with new, more vigorous growth.

Pruning: Dos and Don’ts

  Pruning woody shrubs is both art and science.  Selecting which branches to leave and which to remove allows a gardener to train a woody plant into a pleasing, balanced shape that fits the available space.  Some gardeners use pruning techniques to create neatly trimmed topiary, elegant hedges, or espaliered fruit trees.  Gardeners may also prune roots and branches and remove leaves and buds to train trees to live as bonsai in shallow containers.  Woody plants are extremely adaptable and...

Unlocking the Secrets of Plant Species Names

  A plant’s botanical name, which consists of its genus and species name, may at first look unfamiliar and daunting to pronounce or to understand.  These names are Latinized and so follow the rules of Latin language.  They are intended to describe and give important information about the plants they name.  Botanical names help botanists, horticulturalists, gardeners, and those breeding and selling plants to communicate precisely about specific plants, their varieties, cultivars, and hybrids.  Every plant, historic or newly discovered,...

Landscape Grasses Every Master Gardener Should Know

  Perennial Grasses have many uses in the landscape, including helping to control erosion and adding structural interest to the landscape.   They tend to be very drought tolerant, tough, and seldom will be grazed by deer.  Most grasses are left standing through the winter and cut back in early spring, making room for new growth to emerge.  Some grasses, like river oats, self-seed freely.  Clumps of grasses expand as the plants mature.   Perennial Landscape Grasses Andropogon spp., Bluestem,  Beardgrass,...

Plant Literacy: Common Landscape Plants to Know and Love

Plant Literacy Many people assume that Master Gardeners know a lot about plants.  When neighbors request a home visit from the Landscape Love or Tree Call team, they often have three questions about certain plants in their yard:  First, “What is it?” Some will follow up with, “Is it a native plant?”  And then finally, “Will deer eat it?”  If the homeowner already knows that deer will eat certain plants, then they may ask for advice about how to either...
