Since bonsai is a set of techniques, rather than an individual species, two questions I commonly get asked are "Which species of trees work best for bonsai?" and "Can any tree be a bonsai?" The short answer to the second question is yes, any tree can be turned into a bonsai. Actually, any plant with a permanent wood-like structure, like a cactus or shrub, is a candidate for bonsai. The full answer is longer, as it includes a few if-then's and maybe's and relates to the answer to the first question. You can determine the suitability of a species for...

Back in January I took apart a container full of rooted Kishu juniper cuttings and used the cuttings to create some rock plantings.

I took each clean stone and examined it for the angles that I liked the most and then cast small composite bases to allow the stones to be used at the best orientation. The entire process wasn't...

One of the most common questions that people ask about bonsai is "How old is this tree?"  There is a sense of awe that we gain from the idea that a tree can live longer than a person, and that properly cared for, a bonsai can do the same.   Short Answer: Bonsai can live longer than you!

Drinking "8x8" of water and watering bonsai Water as solvent  Water is the solvent that makes all the chemistry in your body happen, and it is the lubricant that makes all the parts move smoothly.  Still, there is a lot of debate around the benefits of the 8x8 rule of water consumption.  But while the exact amount is debatable, nobody debates that healthy water consumption is essential. Similary, water for plants is critical, but too much water causes problems that may not immediately be apparent. Hydration and Dehydration symptoms in people. If you’ve ever participated in a health tracking challenge...

Three ways you can tell if your bonsai is healthy. We all know when we’re feeling sick, whether it’s a headache, a common cold or the flu - the symptoms are familiar to everyone. Determining if friends or family members are sick may be harder to spot; and when it comes to spotting the health of a plant, it’s a whole new ballgame. As you gain experience caring for your plant, it will get easier for you to determine its health in one glance. Follow these three guidelines to learn what to look for to tell the current health of your plant....
