Paulownia trees, due to its incredibly fast growth and wide applicability, is notably popular among landscape creators, environmentalists as well as timber producers. It is a good addition to any garden or forest plantation because its leaves, flowers and light softwood can make it stand out quite well.
About Paulownia Trees
Paulownia trees have been trademarked in most countries as fast growing trees and for their adaptability thus making them thrilling for use commercially and personally. Native to china, these trees have a unique story and were historically used for decorative flowers, light weight strong wood as well as increasing the quality of soil.
History and Origin of Paulownia Trees
Popularly known as the ‘princess tree,’ the paulownia tree is said to have originated in China, where it has been grown for many centuries. Interestingly, these trees were planted when a girl child was born because these would grow fast and provide wood for her dowry. It is said that the genus takes its name because of the Russian royal family tree, Princess Anna Paulowna, who is the daughter of Russias Tsar Paul I.
Trade routes extended and so did the exports of paulownia seeds and seedlings to Japan and Korea. With time they became a part of the culture and economy of those nations. In recent years, paulownias have reached Europe and Northern America where they have been appreciated for reforestation plans and wood industries due to their fast growth and low ecological impact.
Distinctive Characteristics
Paulownia trees are quite distinguishable owing to their substantially large heart shaped leaves with an onset of early spring flowers. The flowers bloom in lavender, blue and white and have a specific fragrance that attracts several pollinators for instance bees and butterflies. Moreover, these trees are believed to reach up 5m in a single year when climatic conditions are ideal.
The wood that is derived from the paulownia tree is said to be the lightest of them all and is also strong which makes it suitable in the production of musical instruments, light weight boats and even furniture. Its tendency to warp and crack less makes it more appealing to the timber industry.
Varieties of Paulownia Trees
One of the best known species in the world of empress tree is Paulownia tomentosa and this belongs to the genus of Paulownia. This variety is very much appreciated as it grows quickly, has a fleshy display of flowers and is resistant to eco-stresses. Other significant species comprise Paulownia elongata, with its great leaf length and wood quality, and Paulownia fortunei, which is favored by many for being temperature flexible.
Each type of paulownia tree has its own unique set of advantages that enables the farmers to choose the preferable type for them, be it for erosion control, for lumber production or for ornamental purposes.
Preparing the Soil for Paulownia Tree Planting
To guarantee that paulownia trees grow and develop healthily, it is vital to prepare the soil where the trees will be grown. This procedure involves soil analysis, choice of nutrients, and, most importantly, starter preparations.
Testing Soil Composition
The process of preparing the ground to grow paulownia trees begins with understanding the soil composition. In the course of planting, this stage involves conducting a test to determine the pH level, the macro and micronutrients, as well as the physical structure of the soil. Based on understanding the growth requirements of Paulownia, these trees grow in slightly acidic to neutral well-drained soils, with an average pH of 5.0 to 7.5.
Soil tests can be performed on the premises through kits or by utilizing the services of agricultural specialists who have an advanced kit that helps perform a higher number of tests. With the results, one can improve the soil by replenishing it with dormant nutrients or by changing the structural elements to improve drainage and aeration of the soil.
Choosing the Right Fertilizer
The growth of paulownia trees particularly during the early stages can be fostered by proper selection of fertilizer. A complete fertiliser containing nitrogen, phosphorus and potassium in the right proportions will be enough for the mentioned objectives of adequate development of the roots system and canopies.
Manure that has been well decomposed and combined with organic compost is an amenable natural fertilizer, that can enhance the structure and the nutrient quantity of soil without the dangers of chemical pollution. It is recommended that the fertilizer application is done before planting and at any early stage of growth in the trees for the best growing conditions.
Proper Soil Preparation Techniques
Good agronomy includes soil preparation which encompasses busting the compaction of soil by breaking it to a depth of a foot or more for better respiration. It also enables the complete distribution of the fertilizer and other amendments into soil.
Adding compost and other forms of organic material will help improve the level of nutrients in the soil as well as the drainage of the soil which is important for the fast growing roots of the paulownia trees. For a large planting area however, it is preferred to carry out this step with machines in order to make it faster and uniform throughout the planting area.
Planting Process of Paulownia Trees
To ensure a maximum survival rate, planting baru trees requires one to take into account the location, the time of plantation and also the technique used while planting them. If these are forests correctly, growth is more or less ensured.
Choosing the Proper Planting Location
Young saplings of mycological trees grow extremely fast which is why they require ample space while getting planted, additionally they also need plenty of sunlight. A suitable planting site should receive winds getting more than six hours of exposure each day and at the same time should not be exposed to the saplings.
Also keep in mind that the tree grows up to more than 50 feet as it stated above, and should not be planted too close to development trees or buildings, as they get older. The gap between these would allow enough airflow through and would expose them to sunlight as required for growth.
Steps in Planting the Paulownia Tree
Nonetheless, once the spot has been determined, cut the hole for the trees root and ball to fit into, preferably two times as wide and equal in depth. Remove it from its container and place it with caution at the centre of the hole while ensuring no damage is done to the roots.
Once that is done, backfill using soil, this would cover the tree towards the depth itself as it was originally in at the time of the container. Next, irrigate the site in order to get rid of any bubbles the soil may contain. Mulching the areas surrounding the trees would help in preventing the fotosynthetic activities from stopping.
Best Season for Planting
According to the data collected so far, the best time to plant paulownia trees is in the spring or early summer once frosts are no longer a concern as it gives the tree a chance to root themselves and take advantage of the growing season that lies ahead.
In some areas however where the climate is relatively warm so to say, fall planting can also be worth a try as that too allows the tree to root itself before winter. But it doesn’t really matter in which season they are planted, young trees must always be watered regularly and protected from harsh weather conditions.
Care and Maintenance of Paulownia Trees
In order to achieve the best possible results when caring for paulownia trees, the best watering methods and times should be followed as well as implementing proper pruning and dealing with the possible diseases and pests that can harm them. For the very reason that they most likely possess the desired genes that allow them to grow to their full potential, taking proper care ensures that the particular genes are well optimized so that the tree lives to its best utility.
Necessary Watering Techniques
In order for young paulownia trees that have not fully developed to grow a well rounded root system and experience a high growth rate, they need to be watered on the regular. When irrigating it is important to be cautious of over watering as you end up rot the roots, in order to preserve the desired moisture in the soil allow it to dry out between watering sessions.
These trees usually can withstand excessive heat however if they are grown in islands and other drier areas they would require additional water especially during times when a dry spell is likely to occur. Additionally, when there are large plantations it’s recommended to use a drip irrigation system so that the water levels are consistent and do not fluctuate due to harsh conditions.
Pruning and Trimming Paulownia Trees
Pruning is one of the most effective ways to maintain a healthy tree but in addition to that it also promotes the tree to develop a robust structure which is less prone to diseases. Make it a habit to clean up the crossed, broken or dead ends around the stem to encourage healthy so the trees can continue to thrive.
When timber is to be produced, managing to prune the trees first layer of trunks can result in the encouragement of rapid growth coupled with a perfectly straight and branch free trunk. Another important note when caring for trees is to make incisions with sharp tools as that minimizes the overall impact it can have on the tree.
Dealing with Pests and Diseases
Paulownia trees are considered pests tolerant, but they can occasionally be subjected to scalene insects and aphids. Regular inspection of leaves and branches can assist in noticing the infestations in early stages, making treatments like insecticidal soap or neem oil an option.
Fungal like root rot and leaf spot diseases are also infected, which can be worsened by poor drainage or too much moisture. Proper air circulation and adequate soil conditions are vital to reduce such circumstances as well as cutting infected leaves to prevent infection spreading.
Harvesting and Utilization of Paulownia Trees
The final part of paulownia cultivation is the use of the tree for construction and harvesting of the wood. Knowing when and how to cut the tree will ensure more saucers are made from this multipurpose tree.
When and How to Harvest
One can harvest the paulownia as early as five to seven years after planting for timber. However, the wood is more worth it if harvested later. The best time for cutting is during the late winter or early spring when the sap flow rate is at its least level.
A chainsaw or even a manual saw can be used to harvest the tree but one must cut the tree over the roots ensuring the roots left still stand strong if one hopes for the tree to be able to grow again. Next, the harvested wood needs to be dried in a kiln as this will help to keep the shape intact when hot processed commercially.
Usage of Paulownia Trees
Many industries are using the wood that comes from the paulownia trees as they are a better combination of thick strength and light weight. This type of wood is especially in demand for making rubinie furniture and also doors due to its close knit grains and its easy to work with. Furthermore, paulownia wood can also be found in various musical instruments such as guitars and pianos as it is able to make a perfect sound when being played.
In addition to timber harvest, Paulownia trees’ leaves and flowers can be used in compost and as animal feed thus making them useful for agro ecological farming systems.
Selling and Distribution
The demand of Paulownia timber is high and growing, both in the local and international markets; establishing contacts with sawmills and processors would help market the harvested wood.
Other profit centers such as wholesale wooden crafts and biodegradable packets also available. Marketing strategy and critical trends should be developed to gain favorable results in selling Paulownia products.
After looking back on all there is to know about Paulownia trees, it is easy to see why they are so fully recognized for their attributes and benefits. The growth in significance, pace of growth, flexibility, and inclusive use of the tree can enable growers across the globe to utilize this valuable asset. To aid in sustainable forestry and appreciating the many uses of this great tree, you have to follow the guide to planting, nurturing, and cutting down those trees. Great news for the environment and economy; Paulownia trees are proof that nature can grow under careful attention regardless of whether in an individual or a business.
