This article will cover the techniques that I use for late fall maintenance on my double flush pines such as Japanese Red and Black Pines. You may want to consider adapting this to your circumstances depending on the tree and the stage of development/ramification it is in. Do not perform this technique on trees that are in a weakened state or that are not healthy. In early September the new buds that have formed at the tips of the candles should be reduced to two buds. I try to pick…

Yuzu is a type of winter-hardy Japanese citrus tree (read more about It in this article: https://prairiestatebonsai.com/tree-of-the-month-march-2023/). It is very similar to lemon trees. Since the plants are so rare and impossible to purchase in the USA, I decided to grow my own! I purchased a Yuzu fruit imported from Japan at the local Japanese supermarket. I sliced it open and began to extract the seeds.  Having read an article online previously on how to grow citrus from seeds, I did a test of completely removing the skin of the…

Dear Members,Our general meeting on August 7, 2024, was both informative and engaging.

The raffle also included a petrified…

Koto Hime Japanese Maple Photo by International BONSAI Koto Hime Japanese maple originated in Saitama Prefecture in Japan. The foliage is generally light green and is crinkled along the edges. Of all the maple cultivars Koto Hime Japanese maple has the smallest foliage. The leaves of Koto Hime Japanese maple are closely spaced which means that there is an abundance of adventitious vegetative buds, even on old wood. This is an excellent characteristic for drastic pruning thick trunks and branches for developing or remodeling bonsai.Most maples have an opposite leaf…

THINGS TO DO THIS MONTH Outdoor & Indoor:Watering is still a critical job at this time of year. Trees can dry very quickly on hot days. The roots can be damaged or even killed when the soil stays dry for too long, which can have devastating effects on your tree. Now is the time to switch to a low nitrogen fertilizer. The soil should be moist before the fertilizer is applied. Now is the time when trees prepare themselves for winter. Trunks and branches will thicken as materials are…

Outdoor: The most important thing is to water the trees. The second most important is water. Heat and drought can have a significant effect on our bonsai. A tree in a bonsai pot can dry out surprisingly fast in the sun. Check the trees as often as possible and water them thoroughly whenever you water them. Spraying water onto the foliage late in the afternoon can help cool the foliage and container and reduce water loss. Reduce or suspend fertilization. If you are not seeing new growth in your trees,…

A two-year air-layer projectMAY 11, 2024 by JONAS DUPUICHTwo years ago, I picked up a field-grown Korean hornbeam salvaged from the fire that struck Telperion Farms in 2020.
