Tulips in a vase

DEER FOOD

Big Bulbs Uneaten

Chomping down on a rosette of freshly emerging tulip leaves is just the thing to drive away winter’s doldrums — for a deer. Tulips in a vaseCrocuses probably taste almost as good to these creatures. There’s no need, though, for you or me to forsake the blossoms of spring bulbs; plenty of plants don’t appeal to deer palates. Read more

Rhizoctonia damping off

DAMN-PING OFF

Worse than Roman Warriors

I made my first gardening enemies decades ago, within a few weeks of starting my first garden. Not other gardeners but — and perhaps you also have crossed paths with them — with Pythium, Rhizoctonia, and Fusarium. I quickly learned that they were, or should be, hateful not only to me but to all gardeners.

Pythium, Rhizoctonia, and Fusarium are not ancient Roman warriors; they are fungi and, worse than Roman warriors, they lurk everywhere. When they, or one of them, gets the upper hand they cause damping off disease.Beet seedling damping off

Let’s return to my first garden: At the time, decades ago, I was living in a relatively dark apartment, a converted motel room, and was eager to start my first seedlings.

Soilless mixes, as commercial potting soils are (or should be) called, are a mix of some kind(s) of organic materials along with some aggregate, with possible additions of fertilizer, ground limestone, and a wetting agent.Cats with potted begonias

Organic materials in these mixes help sponge up water and cling to nutrients that might otherwise wash down and out of the pot. Peat moss is the organic material traditionally used in soilless mixes. Although it holds water well, it’s initially hard to wet, which is why wetting agents are sometimes added to soilless mixes. Read more
