Outdoor: The trees will need to be moved to a wintering area this month. If you need any supplies such as mulch, heater, or shelving, you should acquire them very soon. Have everything ready so you can put the trees away quickly if needed. Do not bring trees indoors on chilly nights. Be sure to water as needed both before winterizing your trees and while they are in winter storage. Do not fertilize. Remove leaves from deciduous trees and fruit or seeds before putting the trees into the wintering…

Back around 1988, I  took my first bonsai class at Morton  Arboretum.  The classmates shared chippings. This group of potcularia (plus 2 more already under lights) are results  from these cuttings. Developing them and experimenting on them has given me much pleasure over the years with minimal investment.  Arlene Knapp

THINGS TO DO THIS MONTH Outdoor: This is a time to be preparing for the coming winter. Decide where and how you will protect your trees; mulch bed, cold storage house, cold greenhouse, etc. Acquire any needed materials now so you are not caught without needed supplies when it is time to store the trees. Keep trees outdoors on cool fall nights. Do not bring winter-hardy trees indoors. Adjust watering to the changing temperatures. The soil is likely to stay damp longer on cool days, particularly cloudy days. Fertilization…

WOOD-FIRED STONEWARE BONSAI POTS Wood-fired means these pots were fired by hand in a wood-fired kiln after loading the wares into the kiln and bricking up the door. You begin a small fire in the firebox, which you build up very slowly. At the start, you are aiming for about 50-100 degrees per hour for the first 16 to 18 hours. After 24 hours, the temperature reaches 1950 - 2400 degrees. The last firing we did, we fired for 41 hours. During this firing, we burned two cords of…

By: Mark Skipworth, August 3, 2020 I am a beginner at bonsai. I joined Prairie State Bonsai last fall (Sept ?) with no prior experience. My first tree was a juniper left over from a bunch I bought for my son’s yard. (The Home Depot, originally $20 on half price clearance). I blissfully started chopping off branches one Saturday in October but stopped when I realized I had no idea what I was doing. I called a member of the club who graciously agreed to look at my mess…

Where did the summer go??  All of a sudden it is Labor Day with the nights getting cooler and people discussing bringing in their tropicals for the winter! We have three more General Membership meetings before our Christmas Party in December.  Let’s have fun while we get ready for a well-earned rest. August Shows: As predicted, August was a great month for bonsai.  PSBS presented its bonsai show at the Destination Asia Festival at the Morton Arboretum.  Thank you to the many members who showed trees, or worked at…
