They grew quickly and now stand about 6 feet tall. Imagine decorating a Christmas tree you grew yourself, or you could plant them as a living fence lining your property all you need is the seed, the time, and some patience. Asked January 02, 2021, 11:02 AM EST Hello, I love native plants and about two years ago I planted a couple Douglas fir seedlings in my yard. So the next time you’re walking through a forest take a look around you may find a cone you can use to grow your very own Douglas fir. Harvesting the seeds from a cone is the best way to propagate the Douglas fir because it’s the easiest and cheapest method. Grafting is possible but you first need to make sure the rootstock is compatible with your scion, and the scion is taken from a younger tree in its juvenile stage. Water the seedling 1-4 times a month, you can fertilize it once a month but be sure to dilute it with water to avoid damage to the roots. Keep in mind its potential height when choosing where to plant the seedling. Douglas Firs make exceptional Christmas trees. This attractive feature tree, with its distinctive drooping cones, is perfect for any grower who has lots of space and lives in a warm enough region. If you have a greenhouse you can grow them indoors for the first year before hardening them in the following spring, this will make them hardier. glauca Douglas Fir is a large coniferous tree with a pyramidal shaped crown. Keep in partial shade for the first year older seedlings will require full sunlight.Ĭare for your seedlings by keeping them inside for the first 4-6 weeks then hardening them off before you plant outdoors. Plant seeds about 2 inches deep, then cover with soil. Douglas-fir seedlings exhibited a high degree of drought tolerance in the driest year there was only a 20 difference in total dry matter production between irrigated and nonirrigated seedlings. Plant in pots no smaller than 6 inches deep, make sure that your potting soil is has good drainage so that it will hold moisture without getting soggy. Or you can then plant them in pots and then place them in a cold frame over winter. You can put them in a plastic sandwich bag making sure there’s plenty of air in the bag, then place the bag in your refrigerator’s vegetable crisper drawer for at least four weeks. Stratify the seeds, soak your seeds in water for a day then dry then for another day. Once you have your seed rub them between your hands to remove the wings. Remove seeds, this can be done easily after letting the cones dry out for a few hours in direct sunlight then hitting them on a hard surface, or putting then on a baking sheet in the oven at no more than 120☏ until they fully open. You want to make sure that the cones you collect have already begun to open this is to ensure that the seed inside is mature. This means that a cutting taken from a lateral branch can continue to grow laterally, so for best results cuttings must be taken from seedlings or trees in the juvenile stage of development that are sheared once a year.įirst collect cones, you can find the cones on or around Douglas firs in the fall. It is important to note that Douglas firs cuttings can have period of plagiotropic growth, this is more likely the older tree is. Grafting is an option but only as a way of insuring a desired trait from a stock plant is carried on to a seedling.
