Frequently asked questions about the kiri tree
The cultivation of kiri trees requires expertise and experience. We have gained both in the past 12 years of growing kiri trees, cultivating them and marketing the lumber. We are happy to share our knowledge with our customers.

When can I buy Kiri trees?
For our customers in Europe, deliveries take place between April and August. If you prefer a delivery in the months of April, May and June, you usually have to have ordered already towards the end of the previous year.
For cultivation outside Europe, we offer our plants all year round.
For our private customers, the Kiri trees are only available during the planting season from mid-May to mid-September through our partner Blu-Blumen.
Can I buy seeds from your Kiri trees?
No, we do not sell seeds. With Kiri trees from a seed propagation, each tree has a different genetic structure later on the plantation. This leads to inhomogeneous growth, inferior wood growth, and therefore lower wood yield. We propagate our plants via in vitro cuttings so that all our plants have the same DNA. Due to the known and proven genetic quality of each tree, you get healthy and symmetrical root growth, resulting in maximum wood yield.
How much does a Kiri tree cost?
It depends on the number of trees you want to purchase. However, in fact, the planting material is the least cost factor when planning a Kiri trees plantation. Feel free to contact us for more details about our very competive prices.
What conditions do I need to grow paulownia?
In order for your Kiri tree plantation to grow successfully, the key is to choose the right plantation location. Regarding the climatic conditions of the plantation, temperatures should never fall below -22°C or be higher than 45°C for a longer period of time. If there is not at least a natural rainfall of 600 mm – 800 mm during the growing period, additional irrigation should be considered. In addition, a Paulownia plantation requires a sandy, sandy-loose, loose and well-draining soil with a pH between 4.7 and 8.3 and a low salt content. Feel free to contact us for evaluation and assessment of your site requirements.
What is the difference between WeGrow READY® and WeGrow PLUG®?
With the WeGrow READY® you will receive your kiri tree with the perfect conditions for immediate planting in your area. Since the plant including the bale is 25 – 30 cm tall, we can only deliver it to our growing partners within Europe for logistical reasons.
With the WeGrow PLUG® you get an in-vitro plant in top quality, which can be planted on your plantation after an easy handling during further cultivation. Since the plant including the bale is only 3.5 – 5.5 cm tall, this is perfect for worldwide air freight transport even outside Europe.
Can you help me assess whether my land is suitable for growing kiri trees?
Yes. Based on the analysis of the soil samples, we will be happy to prepare an evaluation and a recommendation for you. Please feel free to contact us and we will inform you about what you have to pay attention to when taking the samples.
How much land do I need if I want to grow Kiri trees?
There is no general minimum size, even small-scale cultivation starting at 1.5 ha can be very economical, provided the appropriate equipment and labor are already available.
What support do I get from WeGrow when establishing my Kiri tree plantation?
As our partner, you will not only receive high-quality planting, but also benefit from our 12 years of know-how, our calculation, cultivation, and planting advice, as well as our wood buy-back guarantee. As our cultivation partner, you will learn everything you need to know about how to get the most out of your Kiri tree plantation.
When can the Kiri trees be planted?
The Kiri trees can be planted from the last frost in spring until late summer. Please note that the trees need sufficient establishment time before the first frost in the fall or winter. Regardless, individual rain seasons must also be considered. Please feel free to contact us for more detailed advice on this.
How many Kiri trees can I plant on one hectare of land?
Of our NordMax21®, H2F3® and H2F4® varieties, 400 trees/ha can be planted in the triangular scheme without thinning/intermediate harvesting in a 5 m x 5 m planting unit. However, we recommend planting 660 trees/ha in a triangular scheme with thinning/intermediate harvesting in a 5 m x 3 m planting unit.
Our Phoenix One® variety can also be planted without thinning/intermediate harvesting in a 5 m x 5 m planting unit at 400 trees/ha in a triangular scheme. However, we recommend planting 660 trees/ha or 825 trees/ha in a triangular scheme with thinning/intermediate harvesting in a 5 m x 3 m planting unit.
Do I need irrigation for my Kiri trees plantation (rainfall needed)?
In regions with unpredictable rainfall, at least temporary irrigation is needed for the first two to three years. Usually, by then the trees have developed their first storage roots and are thus able to survive even longer periods of drought.
Generally speaking (with the exception of the ever-humid tropics), artificial irrigation / supplemental irrigation can significantly promote tree growth.
Can I import and plant your Kiri trees in my country?
Determined! An overview of the countries to which we have already delivered our plants can be found at: https://wegrow-croptec.com/en/order-kiri-trees/delivery/

What is the difference between your Kiri trees and Shan Tong?
By the term variety a plant is defined in kind and quality, in that it is distinguished by certain characteristics or properties from other groups of the same genus.
Only Kiri tree hybrids that are registered with the Community Plant Variety Office (CPVO) of the European Union may be called a variety and thus have variety protection.
Currently, a total of seven cherry tree varieties are registered within the EU, four of which are registered to WeGrow Germany GmbH.
Shan Tong is originally a cultivar from China, but according to the above definition it cannot be called a variety, because under this umbrella term a wide variety of genetics exists, some of which are propagated via seeds or roots and sold in Europe. Because it is not protected by variety law in Europe, there is no guarantee which genetics you will get. So there are no clear characteristics that are constant.
