![]() After planting the seedling, keep it in a bright light for several months. To plant your blue spruce tree from seed, dig a hole twice as deep as the size of the seedling’s pot and fill the hole halfway with the same amount of soil. Water deeply, not in shallow, circles, and use the shower setting on your hose rather than a jet-spray to avoid air pockets that could harm the plant. Constantly wet soil leads to root rot and other plant diseases, so water it only when necessary, when rainfall or irrigation isn’t available. ![]() In average garden soil, you don’t need to water your blue spruce tree every day. To ensure a healthy, vibrant blue spruce tree, you need to make sure that you water the seeds frequently after transplanting them. Once seedlings have two sets of true leaves, they’re ready for transplanting. Always water them from below to avoid root rot. After germination, water them regularly, using a water dish. Then, keep the pots in a dark, warm place until they germinate. Start by sowing them in moistened soilless medium in small pots, three to four seeds per pot. Seeds can be started indoors eight to ten weeks before the last frost. You can also grow this perennial in a sunny spot. ![]() Although they are in the milkweed family, they are not listed on most lists of toxins. They are best planted in the early spring and can reach flowering size in about 70 to 85 days. The best growing conditions for blue tweedia are full sun and a moderate level of moisture. Excessive light will cause the seedling to be stunted, so water the seeds every three days. The environment should be evenly moist, but not soggy. The soil temperature needs to be between 72 and 79 degrees Fahrenheit or 22 and 26o C. The perfect growing conditions for blue sapling seeds vary slightly from one species to another. ![]() If you are not familiar with stratification, here is an introduction to how it works. The seeds were also placed in paper envelopes to ensure that they remained moist. After stratification, the seeds were placed in 2-02 metal tins with tightly-sealed lids. Then, stratify the seeds by mixing them with sand that contains about ten percent moisture by weight. Make sure the soil is moist to the depth of the roots and plant blue spruce seeds only in areas that have good drainage and no excessive moisture. If you live in a heavily polluted area, this may affect the blue coating on the needles. Make sure you choose a moist, well-drained spot in full sun. Blue spruce seeds need to be treated with a rooting hormone prior to planting. The process of pre-treatment varies depending on the species.įirst, prepare soil that is well-drained. However, you can do some pre-treatment to maximize the number of germinating seeds and synchronize germination with seedlings. In most cases, they are planted directly from the seed without any pre-treatment. Pre-treatment of blue spruce seedsĬolorado Blue Spruce seeds are generally easy to germinate and have a short dormant period. When using blue spruce seeds, you should place them in a sunny area and prepare a hole that is 1.5 times larger than the seedling’s root ball. The following instructions include planting blue spruce seedlings, watering, and companions. Once the seeds have been treated, the next step is to prepare the growing conditions. When planted outside, blue spruce trees prefer a location that gets full sun exposure, but when grown inside in containers, they thrive with less light exposure. They produce cones that grow up to 6 inches long and also have a silvery-blue color, but they change to brown as they mature. Blue spruce trees are distinguished by their soft and flexible needles that grow in a spiral pattern and can be a distinctive silver-blue color. In the wild, blue spruce can reach heights of 30 meters, but in domesticated settings, it is kept smaller with regular pruning or by growing in containers. During dry periods, you may need to water again after you plant the seeds.īlue spruce (Picea pungens) is a medium to large sized evergreen conifer. Fill the hole with water and let it drain completely before planting your seeds, unless it rained in the last 24 hours. Use your hands or a hoe to dig a hole about two inches deep and three inches wide. Blue spruces prefer sandy or loamy soil, but will grow in almost any kind of soil as long as it drains well. If the spot you choose doesn’t have enough drainage, consider adding gravel or sand to improve it. Find a space that has full sun or light shade and well-drained soil.
