Clivia in the Greenhouse

Europeans discovered clivias in Cape Province, South Africa, in 1815, and soon after some of the plants were taken to England.

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 […]

Do’s and Don’ts for December

Open the vents in your greenhouse on sunny December days, shutting them before temperatures drop early in the afternoon to retain the heat.

The Secret World of Ferns—British fern expert Martin Rickard names five favorites for US gardens

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.

You’re probably […]

Celebrating slate

Walls, terraces, paths, steps, soil, compost, wildlife habitats… second-hand and spoil heap slate can give you the makings of an entire garden.

Its straight lines run […]

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, […]
