Second pic is what I believe to be over watering problems it had at the nursery I baught it from. Third pic is needles going white and drying up on the tree and the rest is of dropped white dried up needles

There is a detailed video on youtube that may help. Search "white pines" by golden state bonsai federation.

Herman,

A good friend, who is from Russia, told me to be nicer and not so gruff with you, so I will try.

You are in mid summer now, and the tree has has buds that extended in to candles and the needles are starting to mature. Correct? The tree looks line it has three years of needles on it, maybe some 4 year needles. These older needles will die and the three and four year needles should be removed as they die, many will start to turn yellow and drop in late February to April in your hemisphere. The tree can be fertilized now, not heavily because of the soil, but fertilized nonetheless. At this stage, you really don't care about needle length or leggy growth, you want to feed to strengthen your buds and to make adventitious buds stronger. When the tree is more refined, then you worry about needles and growth.

Make sense? The big thing is to keep doing what you have been doing, don't let the tree get bone dry, don't let it stay waterlogged. It is on Japanese Black Pine roots, it will bounce back after repotting.

John basically summarized the video that I recommended. It happens to me every fall. Maybe it varies with climate.

Engineer, he is in the Southern Hemisphere, so he is 6 months off cycle with us. So Late August to October in North becomes late February to April in the South.

"gruff"? Never took you for being "gruff" with me Mr Kirby, i was of opinion you were being factual... Thank you for the advice.

repot in spring or this autumn?

I tend to repot everything in the winter/spring now, though there are those who quite successfully transplant in the fall, Late February to late March in your area. Since I repot in the late winter-spring, I would suggest if you want to do fall repotting that someone Like Owen, Bill Valvanis or Boon might chime in, not sure who of the really experienced white pine people does this. The one thing I would suggest though, is that you will probably need to bareroot 1/3-1/2 of the rootball, while eliminating circling roots and some off off the bottom on the remainder, I would suggest protecting from freezing if you repot in the fall until July-August to get the tree growing strong next year.

Hi Herman,

I like your tree very much. Have a question about your region, trying to understand the level of heat. Do mugo pines successfully grow in local landscapes?

Best of Luck,

Augustine

The ideal would be late winter, early spring, around late august early september, but im afraid of going into winter with this field soil this tree is standing in....March is a good time of the year for repotting here, but i only have experience in repotting indigenous deciduous and tropical trees at this time

I will wait for advice(from those mentioned on autumn repotting) before i decide what to do, thank you Mr Kirby

regards
Herman

I had a mugo that did well underneath 30% shade, but i lost it due to bad soil and overwatering in winter... i've moved to a milder area now, hottest is 32-36 celcius, coldest -3 - -6 celcius. I bought the Mugo from capetown, it never goes below 2 celcius there and the summers are extremely hot, way hotter than where i lived previously. they raised the mugo from seed...

don't worry, it will have a dormancy period over winter .

thanks for the compliment

regards
Herman

It's backbudding, I take this as a sign of health and recovery

Good news on the budding. I think a new thread on fall repotting on white pines could be interesting. You might get some good input. I havent done it myself.

Herman,

Repotting for Japanese White Pine can be done at two main times (according to my experience in Japan).  I will explain when things are done in Japan, and you can adapt your timeframe.  The first is early Spring before the candles start to extend.  This is also the repotting time for most other trees.  Go by the tree's behavior; not a calendar.  The second timeframe is late summer.  This is August in Japan.  There is a period after the candles harden but before Fall where there is a "stall" in the tree's growth.  Repotting at this time is also possible, but hard to define in words.  Again, go by the tree, not a calendar.  Repotting at this time should not be as intense and primarily for light soil and root removal.  We use this repotting time to change the angles on trees or put into a nicer container for Fall and Winter exhibitions.

I would advise early Spring as your climate may be too intense during the summer.  Frankly, I'm not sure how well a Pinus parviflora will do in South Africa.  I have friends in Florida who buy cheap ones to see what will happen and they generally last a few years, then croak.  I think this is a combination of intense humidity and lack of cool period.
