    Jpb 20 year progression (with errors inside)

    When a trunk fattens, inner surfaces fuse and thus, trunks fattens more in the inner part of a curve than on the outside. The stiffer the curve, the bigger the enlargement. So when you form a young tree with stiff curves, their stiffness should always decrease from bottom to top.

    Bonsai Log

    Ah, this post made my day. I thought I was the last person to use it. Thanks to Microsoft for keeping binary compatibility for years. Sometimes, I wish I I had the time to fix the little bugs and to adapt it to Android but it is too much of a work for an hobbyist with many trees. Anyone out...

    Trident maple seeds EU

    I have just bought some from Maillot bonsai and https://www.grainesdefolie.com Don't know what they are worth, though.

    JBP Roots

    Empiricism rules. As I always wash pine roots (like any other tree), never add mycelium, as the trees don't die and as they are usually full of mycorhizae a few month later, I do think that your supposition that mycorhizae should stay functional for the tree to survive is wrong. BTW, almost any...

    JBP Roots

    Not a problem. Fungus are micro-organisms. If washing surfaces with plenty of water were a way to get rid of micro-organisms, asepsis in hospitals would be far easier.

    This rule doesn't take in consideration the interest and the pleasure one can have by making bonsai from A to somewhere on the way to Z.

    Jpb 20 year progression (with errors inside)

    2009: the effect of the first error is plainly visible : there is an conicity inversion. Quite put out, I stopped taking pictures of it and started waiting that the neagari's growth absorb the inverse conicity. 2021: the conicity problem is mostly resolved. The needles are a little bit far...

    Jpb 20 year progression (with errors inside)

    2005 repot and another error: big roots should have been trimmed shorter. The first error already begins to show its effect.

    Jpb 20 year progression (with errors inside)

    This is a jpb grown from seed taken from my parent neighbor backyard, sown in spring 2001. It has been grown exclusively in a pot, never bigger than 20 liters. 2004 and already 2 errors : first curve is softer than second's no need to trim the apex and primary branches should have been cut shorter

    JBP Roots

    The first one is really bare-rooted : it has no more substrate between the fine roots. I stand corrected for the second one. Are these two ones more to your liking ?

    I always bare-root my pines when repotting. Small one big one :

    Telperion Pinus sylvestris progression

    Approach grafts are very easy and work well on pines. This wonderful base does deserve needles closer to the trunk!
