In our increasingly globalized society, invasive species have become somewhat of a way of life as we continuously intermix the world’s biota. Plants and animals from other continents tend to find their way to our landscapes and often are here for good. As a gardener, it’s difficult to keep up...
Winter time is somewhat of a downtime for deciduous trees. After a growing season’s worth of beautiful foliage, culminating in the wonderful fall display of color, woody plants enter the long, cold season of dormancy that is part of their annual life. For many of us, this is not a time...
It’s hard to imagine a foodscape without blueberries. My family grows them, picks them, eats them fresh, and freezes a good supply for the rest of the year. Throughout winter, we regularly eat them in smoothies, pancakes, and other baked goods. The fruits freeze well and keep for...
The last thing any homeowner wants this time of year is a cold draft from the outdoors. We humans have become exceedingly good at sealing up all of our indoor spaces in the interest of trapping heat during the winter or cooled air during the summer. These type of improvements in home...
The Fourth National Climate Assessment was released last fall in two volumes, containing information about how climate change is affecting the physical earth system across the US and a detailed assessment of how those changes now, and in the future, will impact our country. The report...
The USDA Plant Hardiness Zones are a standard that most gardeners consider when selecting plants suitable for their local climate. These maps show us the mean annual low temperature for a given location, which helps distinguish the relative cold hardiness of plants, insects and other biota...
Last week, I reviewed the history of USDA Plant Hardiness Zone Maps (PHZM) and their relative change over recent time. These maps are intended to be a guide for gardeners attempting to predict the potential for winter injury to plants, which is a key factor in establishment and successful...
Everyone has their own idea of the perfect Christmas tree. While I am not a person that picks the proverbial “Charlie Brown Tree”, I have certainly felt pity on the less attractive trees on the lot in years past. Whatever your taste, a fresh cut Christmas tree adds a certain bit of...
Nothing symbolizes the holiday season to a horticulturalist like a holiday cactus in full bloom. These fascinating plants are cacti, but not at all like the full-sun, desert loving specimens we commonly think of. Instead, these plants hail from the treetops of forests in Brazil, which...
One of the single best things you can do to improve your garden soil is to add organic matter. By adding significant amounts of organic matter, you are putting fuel back into the nutrient cycle which naturally adds plant nutrients to our soil and lessens (or eliminates) the need for...
