Using Polystyrene chips when repotting

In the second potting of collected material I sometimes use Polystyrene chips in the bottom of the growing on pot. It has three key benefits… In winter the pot stays warmer longer, the roots have free run to grow rapidly and re-potting is a lot easier..and cleaner.

This Taxus has been three years in a feed bucket, it was root trimmed and put back in the same Bucket with new soil and Polystyrene chips in the bottom… as much more growth on the top is required.

I use this technique on Taxus, Prunus and Crateagus. I would NOT recommend Pine and Spruce.

Against all odds in only three years my Myrtle is ready to show

It seemed like an opportunity too good to miss, an old tree with a wonderful trunk that could eventually be a great ‘mother and child’ bonsai, and the price was not expensive, problem was it was a Myrtle Communis. It came from a Mediterranean climate that was sunny, warm and dry for most of the year, I live in the North of England where it is cloudy, wet and cold for most of the year. The previous year I had experimented with a Majorcan Olive from Angel Mota and against all odds it actually did quite well. Should I part with my hard earned cash? Should I risk working with material that (as far as I knew) nobody in the UK had worked before? Should I take a risk? Three years later and the results speak for themselves.

The tree was purchased in the spring of 2009 as a stump with very little growth; it was potted in a VERY open mixture of pumice and bark. When I took a closer look at the base of the tree I noticed that there was a random ‘trunk’ growing across the space between the two main trunks. I pulled this out and planted it in a plant pot; it thrived and is now a sweet Shohin Bonsai in its own right. The base of the tree also had a very severe chain saw cut through the nebari (I guess this was the reason the tree was not expensive)

I needed to investigate the nebari and roots to see if I could rescue the situation of the saw cut, and repot in a mixture more suitable to my climate.

Once removed from the plastic container I discovered a much larger base and far fewer roots than expected, however the tree seemed healthy enough. I carved out the BIG cut and created a ‘deadwood’ area that would finally form part of the nebari. I also removed stumps around the top of the tree and created a ‘natural’ looking taper. At this stage the main concern was health, the creation of mature branches and the development of good ramification.

The tree was left to grow untouched by wire but pinched back to two leaves throughout the growing season, that being from May to December. The growth proved to be quite dramatic this was due to a lot of feeding and keeping the tree in the glass house for 9 months of the year, only moving to the open garden during the warmer summer months. This year in the UK has been the wettest on record and the glass house has been my saviour for many trees.

After the first year I wired the main branches and created a crown for both trunks and the last two years this has been the task. Constant vigilance ensuring that the ramification is correctly maintained, pinching out long growth, keeping the shape in check and creating a pleasing silhouette.

I doubt whether that I will ever have a hot summer long enough to force the tree to flower and even fruit,  this being one of the best features in Myrtle. Maybe I let the tree have a holiday at my good friend Enrico Savini and his garden in Bologna.

Strange pot for a semi cascade Juniper

I have had this juniper for over ten years, I bought it because I wanted a Japanese Juniper in my collection, this little tree has been the most expensive tree in my garden, because I paid so much for this tree I have been reluctant to part with it, most of my collection consists of yamadori that I have collected.

This tree was originally Moyogi with set branches in a typically imported tree. However the tree suffered from vine weevil about 7 years ago and lost but one branch! It has stood in my garden looking very sorry for all this time…. In fact…many of my bonsai ‘friends’ have made fun of me for paying so much for a runt of a tree.

Some times a particular pot can stimulate an idea, this is one such pot. My friend from Holland Hans Van Meer, gave me this pot by William Vlaanderen  because I believed this tree would ‘work’. The idea for this pot is Hans. I think that this runt of a tree will develop into an interesting bonsai… you saw it here first…what do you think?

Repotting and Styling a large Sabina Juniper

I purchased this Sabina Juniper at the Noelanders Trophy in 2009, a year later I repotted the tree into the final planting position I wanted ready for styling. When the tree was collected it ‘appeared’ to lend itself as a semi or full cascade, however I was sure that it would make a very good ‘upright’ tree. The repotting was done exactly 12 months prior to styling. I worked the tree with Enrico Savini as a demo at the Best of British 2011 Bonsai exhibition in Birmingham UK.
