But you’ve got to keep the weeds out

It is surprising how many gardeners have approached me with questions regarding controlling weeds in their asparagus beds. I am glad to see a growing number of gardeners growing asparagus because it is a crop that you have to plant only once for many years’ harvest. It is a delicious vegetable that can be grilled, steamed, marinated or smothered with Hollandaise sauce or cheese....

It’s about time lawn fertilizers were regulated; they’re waging chemical warfare on the Bay

Most of Maryland’s soils are acid. Unless they are limed every three to five years, they are generally too acid for optimum growth, so that any fertilizer applied is wasted and finds its way into the Bay.

I was recently asked to prepare recommendations for the maintenance of a large property with lawns and gardens. While I was evaluating the property, I observed one of the maintenance men on a tractor pulling an aerator followed by a steel roller filled with water. I immediately advised the owner to get rid of that apparatus....

Don’t rototill or cultivate yet

Rototilling, cultivating or even walking on wet soil destroys its structure. Yes spring is here, but frequent rains are keeping our gardens wet.
