Green Workshop: Feed Your Bonsai! – Pellets

Your bonsai may never look like this, but they can be this healthy. This magnificently robust Willow leaf ficus (Ficus nerifolia) is by Jim Smith of Dura-Stone in Vero Beach Florida. The photo is from Bonsai Today, issue 61 and was taken by Jim. Your bonsai depend on you Bonsai do not survive on water, light, and love alone.

Dealing with Stress: Fertilizing & Watering

Almost forgot to mention what Mr. Onishi said about fertilizing his stressed pine (see previous two posts). “After a year of rest in which I didn’t pinch or prune, but during which I gradually gave it higher doses of fertilizer…” That’s it. Not too much to go on, so I’ll try to flesh it out. Most bonsai books and teachers say to avoid fertilizing stressed trees until they show signs of recovery. This is pretty good advice, but still leaves a lot to the imagination. Mostly, I use mild, slow release organic pellets. With ordinary stress (like from rootpruning), I … Continue reading Dealing with Stress: Fertilizing & Watering

In our usage of native soil, we mean whatever soil is already there; in other words, my … Continue reading Field Growing 4: Native Soil

Field Growing 2: Native soil

This impressive Trident maple’s (Acer buergeranum) massive nebari is a dead giveaway that it was field grown. The original article is in Bonsai Today issue 64. I once read a report from Cornell University (I can’t find it; anybody?) about the advantages of planting trees directly into the native soil, rather than the common practice of digging in soil amendments, a practice that may be good for the garden center’s bottom line, but not so good for your plants. If you think about it, it makes sense; if you create a pocket of richer soil, then the roots tend to … Continue reading Field Growing 2: Native soil
