Healthy or Vigorous?? - post from Bonsai Tonight by Jonas Dupuich "One of the more important distinctions to make when evaluating bonsai is whether or not a tree is ready to be worked on. Weak trees need to regain strength and sick trees need to regain health before any major work is done. This goes for detail wiring, heavy bending or major cutback. Repotting is an exception as it may be necessary to repot a tree to help it regain its health. If you’re looking to do major work, making sure that the tree is growing vigorously will help it recover from the stresses of wiring or foliage reduction...."

Thrips An annoying and damaging pest affecting mainly Ficus Benjamin but there are many varieties of thrips that affect both landscape plants and crops. Our bonsai are affected by Cuban Laural Thrips: Gynaikothrips ficorum, and the Weeping Fig (Benjamina) Thrips: Gynaikothrips uzel. Unfortunately when trying to go "green" and use only environmentally friendly pesticides, thrips cause us to get out the toxic kinds such as Bayer's®. To avoid toxic chemicals, cut off the affected leaves to control the population and watch for further infestation. Another type of thrip that is a concern for us is the Chili Thrip: Scirtothrips dorsals which will affect, among others, Schefflera arboricola, Pyracantha angustifolia (firethorn), Acer (Maple), Podocarpus, and Tamarind.

Reducing Florescence Size: The most beautiful aspect of the crape myrtle plant, for the most part, is its gorgeous flowers. Granted, the growth habit of many of the crape myrtles is particularly appealing, and the development of roots and nebari make for a very interesting display as well. What a shame, then, that we have not been able to make the florescences, or flower masses, work for the creation of an even better bonsai - until recently. Read more about Florescence from Clif Pottberg.
A good bonsai matrix/soil: It’s interesting to me how complicated people make the subject of creating a beneficial soil for bonsai, or for any plant in a pot for that matter. It’s not hard to do, but it must start with the right concepts. Actually, since a good potting soil is such a specialized product, it would rightfully be called a “potting matrix” for there is often no natural soil involved in it. Let’s start at the beginning. We’ll use the term “soil” since it is the term most people are acquainted with, no matter what the particles are composed of.

Trunk Lean: There are a number of bonsai rules which have been handed down to us to help us create the look of the real tree.... we often create thicker and more tapered trunks than you would likely see in every tree. Then there is the old Japanese rule that a bonsai should be bowing, welcoming us in. In other words it must be leaning towards us. Read more about Trunk Lean from Clif Pottberg

Transpiration: Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. Transpiration also includes a process called guttation, which is the loss of water in liquid form from the uninjured leaf or stem of the plant, principally through water stomata.... How much water to plants transpire? Atmospheric factors affecting transpiration.... read more
