Hi all, wondering what soil mix has produced the best health for Japanese black pines here in Colorado. Also, what particle size have you had success using? My plan is to go with a Boon mix at 1/16, but open to ideas. I just bought a black pine (http://www.driftwoodbonsai.com/store-1/japanese-black-pine-68) from Driftwood Bonsai and it is ready for a bonsai pot.

Hi all, I am wondering about members experiences with county water restrictions. It’s not possible to skip watering days when it’s hot, windy, and dry, for even native trees like rocky mountain juniper, limber pines, and ponderosa, let alone non-native plants like acer palmatum. Maybe the degree of watering does not rise to a problematic level? It’s not like I am watering a golf course here. To be clear, no one has raised this as an issue, it just popped into my mind since we’re in the process of moving to a home a few miles away and the prior owner taped the utility water restrictions to the watering system. Interested to learn what others think. Best, Josh

How do you all handle these wide weather shifts? Are you still leaving your trees in protected spaces? Some of my maples are breaking buds, but temps are still getting into the freezing range at night. Right now I am moving things in and out of my garage. Are there certain trees you are leaving out at night at this point (junipers, pines, etc.)?

With repotting season just beginning, I’m getting ready to work on a mugo pine and shimpaku juniper. Wondering what soil compositions folks have used. I have been going with a pumice, lava rock, akadama mix (heavy on the akadama). Any other suggestions?

After struggling through this past summer with 90-degree days and low humidity, I decided to build a bench that offers some protection from the intense Colorado sun. Since we really cannot go anywhere these days and late fall/winter is a slow time for bonsai, I used some downtime to create this display bench. We have a small side yard, so I had to make something custom to fit in our space. After searching different forums and sites I landed on the bench below (which is a mashup of several designs). The top-level is set back to allow light to reach the second tier. I’m excited to see how it works this spring.

Hi all, I’m hoping to get your help regarding repotting Japanese maples. I purchased two garden center maples (mikawa yatsubusa and Sharp’s pygmy). I am wondering how much root mass one can take when repotting acer palmatum as bonsai. I am aiming to repot these in the spring, just as new buds emerge and am trying to order some pots ahead of time. I think I tend to use pot sizes that are too large. Right now, these trees are in 7 and 5 gallon pots. Any suggestions would help! Best, Josh

Hoping to get some help with the structural design of this black pine I got from nursery stock. I am new to black pines but decided to get one since they seem like such a great tree to shape over time. This one seems to have quite a strong apex, that really dominates the rest of the tree. In trying to train this tree as a bonsai, I wonder if it would make sense to remove that section of the tree just above the next top two branches. I’ve been reading a lot about how to shape these trees and it seems like that section might be causing a bit of imbalance. However, I don’t have much actual experience with black pines, so any advice would help.

As we begin to move into the colder months here in Colorado, I’m hoping to get some advice on overwintering. For conifers (e.g., atlas cedar, nana, and hinoki) and deciduous (e.g., trident, acer, beech) trees that can stand up to colder temperatures, how much protection do folks generally provide? We live in the metro area and don’t have quite enough space for a greenhouse, but we do have a garage. I’ve also heard window wells can offer some protection (which we can make use of as well). Thank you in advance!
