Repotting Oriental Lilies – a project for those late Fall rainy days.

I was digging over a garden bed last week and dug out several Oriental lily bulbs. When you dig out “oriental” or “Asian” lilies, be sure to use a garden fork, not a spade. A spade will slice into the bulbs. These had not been dug for five or six years so it was time […]

Recently, I was invited to hike in the Oregon woods with a group of fern enthusiasts—several from the UK. The group was on a three-week botanizing road trip throughout the Northwest.

Grow Your Own Avocado – A perfect winter greenhouse project

Most of us have tried to grow an avocado (Persea americana) tree from seed. Although an avocado plant can be grown in any large, indoor room, it’s also does well in a heated greenhouse. Both heat and humidity must be kept fairly high for an avocado tree to thrive. To grow an avocado from seed, […]

Waking up to a world with less water

Where would we be without water? I recently returned from California, where I got a sobering look at the possibilities. The drought there is a wakeup call for all of us—even in places like Chicago or the East Coast that aren’t suffering right now—to think hard about how we use this precious resource. There are […]
