Is my tree growing a sweater?

If you have an eastern hemlock tree on your property and you live in the Northeast, chances are that you've noticed that it gets woolly at this time of year. Is the tree growing a sweater?

Actually, it's a invasive insect from Asia, the hemlock woolly adelgid, producing egg sacs that have the appearance of wool. The photo above was taken today and shows egg sacs on the underside of a hemlock in Cambridge, MA. These insects suck nutrients from the tree while also injecting a toxin into the tree. After several years of a heavy infection, the tree will die.

If you only have a few hemlocks on your property, you can treat your trees with chemical treatments that kill the adelgid. There are also some more environmentally friendly biological control approaches being developed that use insect enemies of the adelgid to reduce infestations.

Sophisticated gardens increase property value

The gardens that create a lush frame around a home are one of the first things that potential buyers notice. A recent article in the Boston Globe points out that attractive landscaping can increase property value by almost 13 percent. This study by Virginia Tech scientists noted that the level of sophistication of the landscaping can raise the value of a home by up to 42 percent. If you are thinking of selling your home, now may be the perfect time to spruce up your garden to attract more potential buyers.

Wild Urban Plants of the Northeast

What's that pesky plant that keeps popping up in your beautiful urban garden? Chances are that Peter Del Tredici can help you figure that out in his new book, Wild Urban Plants of the Northeast. Del Tredici is a research scientist at Boston's Arnold Arboretum. This book isn't a "how to kill a weed" book, but is more of a "how can I appreciate this amazingly persistent plant" book. It will likely change how you view the little green monsters poking up through the sidewalks and urban habitats of the South End.

Peter is giving a talk about this book at the Harvard Museum of Natural History, tomorrow, April 11th.

Grow your own urban vegetables

Urban vegetable gardening is becoming increasing popular across North America. South End Gardens can help you design an urban vegetable garden that will provide fresh vegetables throughout the summer, regardless of how much space you have on your roof deck or in your yard.

These French breakfast radishes are already growing in a Shawmut Ave rooftop vegetable garden we built last year. They'll be ready for harvest by the end of April.

Plant ID App for your iPhone

Have you noticed a tree or shrub around the city that you'd love to add to your garden, but didn't know it's name? Botany Buddy is a useful app for your iPhone that can help you identify common trees and shrubs on the go.

Alternatively, just take a photo of the plant with your phone and post it on our Facebook Wall. We can figure out what it is and whether it would grow in your garden.

Leafing out in Union Park

With the warm temperatures over the past few days, many plants across the South End have woken from their winter slumber. In Union Park, this climbing hydrangea is rapidly leafing out.

Spring is here! Start planning your garden

As we emerge from the winter into (a very wet!) spring, it's the perfect time to check out your garden space and start dreaming of what you want it to look like this summer.  Take an inventory of what plants made it through the winter and think of what new elements you might want to add this year.  Want to try growing your own vegetables this year?  Need to add more continuous color with a diversity of annuals?  Don't have time to water your plants and need an automatic watering system?
