A Greener View

Have you heard that the United States Department of Agriculture has released a new plant hardiness zone map for the United States? You may have heard that this map indicates global climate warming.

Does the new USDA map offer proof that the climate is warming? No, it does not. Is the climate changing? Of course it is — it always has been and hopefully always will be. The 2012 USDA ...

Q: I have nine dwarf fruit trees (including apple, peach, pear and plum). I will be moving this coming spring or early summer. These trees have been on my property from one to four years. Some have produced fruit, and some have not. Is it possible to transplant these trees to my new home with any success? If so, how should I do this? Once I move, the house will be vacant, and the trees will get ...

One way I've found to pick the best plants for my garden is to look at the All-America winners for the New Year. If it has been tested and approved in the All-America Selections (AAS) testing program, I can trust the plant to grow in my yard. Almost 40 test gardens from Alaska and Canada to California and Florida comprise the AAS. It's very useful to have a test garden in a similar climate as y ...

If you watched the awesome Rose Parade, you probably saw the Bayer Advanced Garden of Imagination float that won the Director's Trophy for outstanding artistic merit in design and floral presentation. Among the 20,000 roses was the world debut of the 2012 All-America Rose Selections Winner, Sunshine Daydream.

The float told the story of the Walheim brothers, who daydreamed in their child ...

As we begin 2012, we get to reflect on the changes we want to make in our lives. Many of us are gardeners because we enjoy the seasonal changes in the landscape and because we can make changes to our gardens. Even in the middle of winter, we're thinking about gardening and planning on making changes as we get each new garden catalog in the mail.

Resolve to try new plants in your garden. ...

Q: We were given a Christmas cactus, and just a week after we got it, all the flowers and flower buds fell off. What did we do wrong?

A: A Christmas cactus can be sensitive to too-warm temperatures and too-dry conditions. They are not true cacti and should not be allowed to dry out like a typical desert cactus. In nature, they're like many bromeliads because they're epiphytic plants that ...

Q: We'd like to spend a month in Florida this winter, but we can't find a house sitter for the whole time that we'll be gone.

Can we leave house plants well-watered before we go, let them sit for two weeks and water them well when we get back? (We normally water every three to four days to a week for all the plants.) Or should we harden them off by not watering as much for a while before ...

Winter is beginning, and most of us are just starting to dream about next summer's garden. To help get your own ideas flowing or for the gardener on your gift list, I have a few books that you can read by the fireplace to warm your green thumb.

"No Guff Vegetable Gardening" is a fun approach to vegetable garden books. Written by a pair of Canadians, it's still appropriate for a ...

Are you looking for some gift ideas for the gardener on your shopping list? I tried a few tools this summer that really helped make gardening easier.

First, we have a pair of CobraHead weeding tools. Shaped, as you might expect, a bit like a cobra about to strike, they help pull weeds out of the garden. The flattened end of the sharp blade easily cuts through the soil to undercut weeds. ...

"Eat Your Roses" is a wonderful little book that proves you can have your flowers and eat them too. Author Denise Schreiber covers 52 species of edible flora that are found in flower, vegetable and herb gardens. The first rule of eating flowers is to be positive of the identification that it is an edible flower and that it hasn't been sprayed with anything toxic.

Edible flowers ...

It isn't officially winter yet, but as people in many parts of the country know, winter weather doesn't always wait until the solstice to begin harassing our gardens. As we bundle up with coats and blankets, we can protect some of our most vulnerable landscape plants with a jacket or blanket of their own.

Why bother protecting plants from the cold? Shouldn't they be able to handle winter ...

Houseplants can be a lot like pets: They both require some care, they can have short or long lives and people can get pretty attached to them. Unlike pets, though, plants have been proven by NASA-sponsored research to improve the air quality of homes and offices.

Houseplants fall into several loose categories. Foliage plants are grown for their leaves. Flowering plants are grown — ...

Q: I was raking leaves when I noticed lots of small weeds coming up in some of my flowerbeds. I was surprised, as I thought weeds should be coming up in the spring, not the fall. I'm wondering if I need to do something about them. Or will the winter weather kill them?

A: It may come as a surprise, but there are plants called winter annuals. There are also perennials that grow well or spr ...

Q: We have several old oak trees and some elm trees on our property. Back in the early summer, we were told not to prune them until winter. We're now heading into winter, and we want to have several low limbs removed. Is now really a good time to prune these trees, and if so, why?

A: Late fall through winter and into early spring is the best time to prune many shade trees. Many of these ...

A few weeks back, I wrote about how average people could join together as citizen scientists to produce very important data about birds by participating in Project FeederWatch, managed by the Cornell University Laboratory of Ornithology. It's funny how people who know almost nothing about birds can help people who are so passionate about birds that they study them as part of their life's callin ...
