Suzuki, Santini & One Big Sabamiki

hollow

I pulled this distinctive bonsai off of a gallery on facebook that was posted by Francesco Santini. There isn’t much information provided and I don’t read Italian anyway (Free Translation nonwithstanding), so I can’t say much about this tree except that the hollowed out trunk caught my eye.

An unusual tree
I have seen very few trunks that have been so completely hollowed (from side to side anyway, if not in depth). It looks like it might be a Ezo spruce though I could be mistaken. If it is an Ezo, it must be quite old to attain such size as Ezos are very slow growing. I like the first branch, it almost serves as a second trunk and is not a bad little bonsai in itself. Overall, I think that this is a excellent tree with great balance, and would be noteworthy even without the distinctive hollow trunk.

Here’s another tree from the same gallery that caught my eye. Though it’s a juniper, the reddish bark and the deadwood remind me of the Manzanitas in California’s Sierra Nevada mountains.

Junipers: Don’t Pinch Too Much!

Even if you’re one of those curmudgeons who complains about the overly sculpted look of some Japanese bonsai, you’ve got to admit that this powerhouse Shimpaku approaches perfection. That trunk draws your eye like few trunks anywhere, with its single living vein, mysterious hollow at its base and the spidery fingers and hole at the top. But it’s the tight lush foliage that I want to point out here; the result of some serious trimming and pinching. The photo is from our Juniper book. Artist unknown.

A question about pinching on Michael Hagedorn’s site
The following is from the Seasonal section of Crataegus Bonsai (Michael’s site). It starts with a question by Ron Verna: I have a shimpaku juniper that I’m concerned about it has lost a lot of foliage and doesn’t look as bushy as I would like. Would piching and repotting help?

Michael’s reply
Hello Ron, Although it is difficult to advise without seeing an image, in general, we pinch far too much on junipers. I recommend cutting the longer shoots that push out of a foliage pad with a scissors, a couple times a year, rather than trying to create density with pinching. That tends to greatly weaken junipers.
Repotting can rejuvenate a tree that is metabolically slowing down because the pot is full of roots.

You can pinch with your fingers (but not too much!), and….

Fall Fertilizing: Nitrogen

OR-01

Fish seaweed is mild and well-balanced for fall fertilizing.

Reduced nitrogen
Horticulturists, bonsai teachers and others have long been advising people to reduce nitrogen fertilizing in late summer and fall. The keyword is “reduce.” Some nitrogen is necessary when you fertilize otherwise the phosphorous, potassium and other nutrients can’t do their job properly.

Fall growing season in mild climates
Here’s what Michael Hagedorn of Crataegus Bonsai has to say about nitrogen and the fall growing season: “We might also begin thinking about fall fertilizing. I think fall fertilizing is more important for bonsai, particularly developed ones, than spring fertilizing. In Japan more fertilizer is sold for bonsai in the fall than in the spring. If you live in the Pacific Northwest or other areas with a long, mild fall, re-fertilizing the trees is very wise as it is as long and nearly as productive a growing season as spring.

Pests #2: Controlling Scale by Michael Hagedorn

8503552

These little critters with their protective helmet-like shields are just one variety of the approximately 8,000 species of scale. Though not all are harmful to your bonsai, the ones that are, need to be taken seriously.

Here’s what Michael Hagedorn has to say about scale
They’re here again…scale are emerging from their eggs underneath their shields, and beginning to crawl.

This is the time to control them. If we sprayed during the winter we wasted insecticide on protected eggs. In June they mature and begin moving around the plant, and can be controlled with oils. All-season oil or Neem oil work. Early summer through the warm months they are active.

It’s very important to identify when to control what. If we spray with the right insecticide or fungicide in the wrong season, we waste time and money and maybe give a beneficial organism a hard time.
