Healthier plants mean more oxygen and a healthier you

While relaxing in my hammock under the shade of our mature cherry bark oak trees, I realized that my heritage river birch tree, growing in front on my house, was expressing air pollution symptoms. The older leaves were turning yellow and beginning to fall. I noticed similar symptoms on the magnolia and crape myrtle.

Lots more good can come from your garden

For a feast-full fall garden, now is the time for planning and planting. On the other hand, if you want to take it easy after your spring and summer harvests, then simply plant a cover crop of winter rye in those areas where the crops have been harvested.

Not until we compost everything, including Uncle Charlie

I’ve been chastised by a Bay Weekly reader for not supporting commercial organic farming. So I’m explaining my position. I have conducted research in composting and in compost utilization for more than 30 years, so I am very familiar with the limitations of organic farming.

Starting now, you can harvest what you’ll eat

If you planted long-day onions this spring, you will notice that they are forming bulbs. If you accidentally planted short-day onions, you will be feasting on onion tails for the rest of summer.

Even the Bay Gardener doesn’t thrive on vegetables alone

The latest addition to my fleet of boats I’ve built or restored is a 16-foot strip sea kayak. This was a two-winter project requiring some of the skills I learned when building my 16-foot strip canoe. However, this project required having to scarf all strips for added strength and building a deck to fit snugly over the hull....
