How to plant.

Planting Kiri trees properly

After the proper preparation of the land and marking the planting sites, the delivered plants should be placed in the ground as soon as possible. After all, every day of storage of young Kiri trees (Paulownia) at the edge of the field means a loss of quality. Therefore, we recommend that you have sufficient manpower and machinery on site and ready for use for the period of planting. We can also advise you on how to avoid this potential loss of quality. With the planting technique described, one worker can usually plant about 1,000 trees per day.

Planting Kiri trees at the right time

Depending on the climatic region in which you establish your Kiri tree plantation, the ideal planting period varies. In temperate and subtropical latitudes, planting can begin as soon as there is no longer a risk of late frost. A frost occurring after planting can severely damage young Kiri trees. From the day of planting, the trees should have at least 12 weeks to become established before fall and winter set in.

In tropical regions, planting may be possible year-round. However, rainy and drought seasons must be considered when selecting the optimum planting date.

The ideal planting scheme

Cultivated land is an increasingly expensive production factor, which is why most growers – including us – nowadays plant Kiri trees in a closer association. Thus, earlier crown closure can be achieved and the area can be used much more efficiently. When a closer planting site is selected, intermediate harvests are made to prevent competition between trees. This is because if the trees compete for light for too long, the length growth of the main trunk and the growth of branches are promoted, to the detriment of the thickness growth of the trunk. Intermediate harvesting, on the other hand, provides the trees remaining on the site with sufficient light to achieve the desired trunk diameters in the shortest possible time. Intermediate harvesting also leads to a significantly increased yield per unit area. This is because Kiri logs from intermediate harvests with diameters of 28 to 32 centimeters also achieve very good selling prices on the market.

A precise triangular scheme makes intermediate harvesting significantly easier. Instead of thinning out individual trees and possibly damaging neighboring trees in the process, entire diagonal rows can be harvested efficiently here.

Planting Kiri trees manually

For many years, planting with a planting tube or a planting stick has proven itself to us and our customers. The advantage of this planting technique is that the planter does not have to bend down to plant the trees. Thus, he can do his work for a long time without any worries and reliably. Also, the use of a planting tube ensures that the plants are always placed in the ground at the correct depth. This is because setting the root balls too high can cause them to dry out quickly, while setting them too deep can cause stem rot. The planting tubes, on the other hand, have a depth limiter that always ensures the optimum planting depth.

Planting Kiri trees by machine

There are a large number of automated planting machines on the market worldwide, which are also suitable for the plantings of our WeGrow READY range, or can be adapted by simple conversions. If possible, the machine used should be controlled via a GPS signal. RTK receivers offer the greatest possible precision here, with a planting accuracy of up to 2 cm. An exact distance between the trees and the tree rows significantly facilitates the subsequent maintenance measures. The use of GPS-controlled planting machines also eliminates the need for very labor-intensive planting site marking.
