Greenhouse temperatures of 60° to 70° F, a six-month growing season, long day, adequate. Douglas-fir (Pseudotsugamenziesii (Mirb.)Franco), lodgepole pine (Pinuscontorta Dougl.), and white spruce (Piceaglauca (Moench) Voss) seedlings, each represented by two seed lots, were grown in Styroblock containers in a greenhouse and plastic shelter house from February to January The seedlings were exposed to two nitrogen (N) treatments and three potassium (K) treatments Cited by: Frost damage.

Frost can affect many plants, and is particularly damaging to tender new growth and blossom in the spring. The risks of frost damage can be reduced by taking some simple steps to protect the plants in your garden.

Douglas Fir Seedlings, approx ″ tall. Douglas Fir have been planted as lumber and timber stock for decades, and established themselves early in the 20th century as one of the primary species grown as Christmas trees. Today Douglas Fir are almost universally harvested from tree farms, not from the wild.

Responses of Douglas-fir seedlings were studied for 3 yr following eight vegetation-control treatments in three western Oregon clearcuts.

The objectives were to determine seedling growth response to different areas of spot vegetation control and to determine the relative influence of early woody and herbaceous competition on seedling growth.

Douglas Fir is susceptible to spring frosts so always plant with good air drainage. Cones are not a litter problem. Many buy Douglas Fir seedling for Christmas trees. Douglas Fir are also picturesque ornamental trees, good windbreaks, and can be sheared as a hedge and. are very fragrant. Introduction.
