    Scots pine yellow needles

    I'm struggling to keep this Scots pine healthy. My issue for the past 3 years is that the previous years needles continue to turn yellow (tip first) and drop off. This makes it extremely leggy and difficult to use any back buds. I originally thought that my soil mix was not draining properly...

    Arakawa Maple

    Does anyone have a good resource for Arakawa japanese maple? It looks like there are some on Brussels but I'm looking for more of a starter plant (1 gallon graft or an airlayer preferably). I am having a hard time locating these online and even harder in person. Most online are out of stock...

    I keep having issues with my beech leaves every year. Any ideas of what may be causing the issue? I have been keeping these in a free draining mix of turface, pine bark, and expanded shale. The leaf margins continue to brown. They start off spring well and progressively get worse through the...

    Japanese black pine sacrifice reduction

    I have been growing this black pine in a combination of colanders and 2 gallon tub over the past few years. It was grown from seed but somewhere along the way I lost track of exact age so I'm not exactly sure how old. I'd guess around 10 years from seed. My question is the following and best...

    Japanese maple progress

    I figured I'd track this maple's progress along the way. It's still obviously got a long way to go. It was grown from seed in 2010 so 7 years old this spring. I posted the front that I envision along with where I'd like to take it in the future and where it is after some minor cleaning up...

    What's the best time to do big bends on these? Early spring or is fall an acceptable time? The portion of trunk is about 1" in diameter. Just want to put more movement in this section.

    Maple leaf removal in fall?

    I've read from those like Owen Reich that people remove the leaves on their maples in the fall as opposed to letting them fall off naturally. Do people do this? I've heard two sides of the argument. One is that the mechanical removal prior to natural drop is that it aids in the prevention of...

    Pesticide and Insecticide Safety

    Maybe I'm am one of the more paranoid people but I was wondering others thoughts on why there isn't a forum for insecticide and pesticides and using them safely. I am one that would really like to see something like this in the future. I understand that these are all different but seems like...

    Zerotol and Pines

    Does anyone use Zerotol as a pine fungicide treatment? Does this require protection of the soil? I've read that you should drench the soil on maples? Is there ever a fungicide treatment on pines that does not require protection of the root zone?

    What's on this juniper?

    This just started showing up on juniper. I pruned out a couple of branches that have this. Should I be concerned? Is this a gall of some sort? How is the best way to treat this? It looks bad on the tree. I'm referring to the yellowish like growth on the branch. Thanks

    Trident Maple ideas?

    I took a few pictures today of my trident maple that has been growing in the ground for the past 3 years. It's starting to approach the size trunk that I want. Some root work was done in 2010 prior to putting in ground so I'm not quite sure what the roots are like at this point. I was hoping...
