A Look into the Growth, Care and Varieties of Pine Trees
One of the most popular trees
Pine trees are beautiful conically shaped trees that are often a part of many societal landscapes. Pine trees are known to be one of the most ecologically important constituents of the environment.
Pine trees are evergreen, they sport a green look throughout the year. The Pine tree generally tends to grow around 3 to 0 meters tall, differing from variety to variety. Most of the Pine tree varieties maintain a common height of around 15 to 45 meters tall. Pine trees are also lauded for being one of the longest living trees. A Pine can easily survive anywhere around 100 to even 1000 years.
Pine trees are also popularly referred to as conifers. Conifer is the term used to refer to trees that have cones. The Pine tree is one of the most common and popular kinds of conifers out there.
What does a Pine Tree Leaf look like?
The adult leaves are known as needles
The foliage of a Pine tree is known to be unique from other general trees. The Pine tree leaf can be of four different kinds. These are stated below.
- The seed leaves or cotyledons of the plant appear in a whorl of 4 to 24.
- The juvenile leaves appear on seedlings immediately after planting. The juvenile leaves are generally green or bluish-green and seem to be arranged in a spiral form around the shoot. These leaves are around 2 to 6 centimetres long and stick to the plant for around six months to five years, and sometimes even longer.
- The scale leaves are brown and rather tiny. As indicated by the colour of the leaves, the scale leaves are not capable of performing photosynthesis. Much like the juvenile leaves, the scale leaves are also arranged in a spiral form around the shoot.
- The adult leaves, also known as needles of the plant are green and thus capable of performing photosynthesis. These needles are bundled in clusters known as fascicles and each fascicle can consist of around one to seven needles.
The Male and Female Pine Cones
The cones consist of pine seeds
Most Pine trees are monoecious, that is, the tree consists of both pine cones of both sexes. There are also certain sub-dioecious species where the number of male pine cones might be larger than the number of female pine cones or vice-versa. However, no variety of pine trees consists of just one sex of pine cones.
The male cones are typically small in size, measuring just around 1 to 5 centimetres long. These pine cones are present for a shorter period, mostly around the spring or autumn season, and fall off soon after the pollen is shed.
On the other hand, female pine cones can take as long as 1.5 to 3 years, the period differing for different varieties, to mature after they are done pollinating. The female pine cones are generally around 3 to 60 centimetres long.
On reaching maturity, the pine cones open up to release the seeds that can be used to grow a separate set of Pine trees. However, in some varieties, like the Whitebark Pine, a bird needs to break open the pine cone for the seeds to get released. There are also certain varieties of pine cones that lay as they are for several years until an environmental cue triggers their opening and thus initiates the release of the seeds. This act of taking such help from the environment is termed as serotiny.
Growing Pine Trees at Home from Pine Seedlings
Can be easily grown at home
Here is a step-by-step guide to growing Pine trees at Home with the help of Pine seedlings, all by yourself.
- Start with digging a hole that is around twice as large as the root ball of the Pine seedling. As you dig, make sure that you save the removed soil for future use.
- Make sure that the hole you dig is deep enough to fit the Pine seedlings and keep it in level with the surface of the soil.
- Carefully take the pine seedling out of the container that it comes with while purchasing.
- Gently spread the roots out so that they do not seem to be circling the mass of roots. If necessary, you can also trim the roots a little to prevent them from circling yet again.
- Slowly and carefully place the Pine seedling into the dug spot. Make sure that the Pine seedling is standing straight.
- Fill the empty dug area around the Pine seedling with the removed soil that you earlier saved. As you add the soil, keep pressing it down to avoid the formation of air pockets.
- Once the hole is full, fill the rest of it with water. Allow this water to drain out.
- Add more soil to completely cover the dug area. Flush with water once again.
- If the soil seems to settle down after the addition of the water, top it off with some more soil. However, make sure that the soil you add is not going up enough to touch the trunk of the Pine seedling.
- Finish it off by applying some mulch around the tree. However, make sure that even the mulch should not touch the trunk of the Pine seedling.
Pine Tree Care
Easy to grow and care for
Pine Tree care is often made out to be a big deal. However, that is not the case at all. Pine Tree Care can be a piece of cake if you follow some basic care tips while growing the plant. Here is a brief look at some basic Pine Tree Care Tips that will make caring for a Pine Tree an effortless task.
- The Ideal Planter: An ideal planter is neither too large nor too small following the current size of the plant. Make sure that the planter you choose is also deep enough to accommodate the growing roots of the Pine trees. The planter should also contain some drainage holes at the bottom to flush out the excess water that could otherwise harm the plant.
- Potting Mix for the Plant:It is important to plant a Pine tree in soil that is rich in structure. It is also important to make sure that you use a well-draining potting mix. Pine trees love growing in the sandy soil. The plant also prefers growing in some slightly acidic soil.
- Light Needs:Pine trees love the full sun. The bright sunlight is necessary for the Pine trees as it aids in the plants’ growth. The plant absorbs as much sunlight as it can to help in reaching its full growth potential. There are also a few varieties of the plant that tend to grow well in partial sunlight. Many Pine tree varieties are also known to be quite intolerant to shade.
- Watering the Plant:When planted newly, Pine trees need to be watered every few days to maintain a moist consistency of the soil. After a month goes by, you can shift to watering the plant once a week. Once the Pine tree is well-established, it can easily tolerate long dry spells and thus, need not be watered as frequently.
- Fertilizing the Plant: The Pine tree does not require fertilizing in the first year of its growth. During the first fertilization of a Pine tree, it is advisable to use around 0.90 to 1.81 kilograms of a 10-10-10 formulation fertilizer on every square foot of the potting soil. In the following years, you can shift to 0.90 kilograms of fertilizer for every inch of the diameter of the trunk.
- Pruning the Plant: A Pine tree can always be lightly trimmed to control the size of the tree during the late winter season. However, it is always advisable to not prune completely healthy pine trees. An evergreen Pine tree should never be heavily trimmed. To remove unhealthy growth, it is enough to prune back just to the branch collar.
