A Case Study for Applying the Water and Sugar Equations - Repotting the Risky Rose

Source material: 3/19/2021

            Hola bonsai amigos! Today is a great day because not only does your friendly neighborhood microbiologist (me!) receive his second Covid vaccine dose, but my immunized arms also come bearing another present to the bonsai community. As spring continues to march on, so too does the blog's coverage of my giant rosebush bonsai - this time the rose's latest repot reveals two fundamental equations of life to consider when manipulating bonsai or any plant.

            The "Risky Rose" was the second major repot I did this year; returning readers will recall from last week's post that this operation involved another of the largest trees in my collection - a yardadori/landscape origin rosebush turned bonsai. As discussed in the previous post, now that the tree has recovered several years after its initial transplanting endured a cross-country move and survived its first Ohio winter, our rose has definitely earned renewed attention this year. For now, I'm calling it the "Risky Rose" because it needed severe root reduction in order to change its planting angle and lift the upper half of the trunk out of the pot. Read on to understand the motivations behind this bold action, including what steps were taken to ensure this radical root reduction could be done safely.

            As with my last repotting post, "Repotting The Monster Mulberry - Revisiting the Basics", this repot was done with the help of my friend in the Columbus Bonsai Society, Kevin. Thanks, Kevin!

Origins of the Risky Rose & Steps for Transplant Recovery

 Source material: 2/09/2018

            As the weather continues to warm up and frosts become rarer here in Ohio, repotting season is on its tail end - if you're not already finished with it. I'm hoping to squeeze in my last few this week and also plan ahead for future bonsai by sowing my newest batch of seeds. In the spirit of finishing the repotting season, I was also planning to post the second major repot I did this year - once which involves substantial risk and reward. For now, that's all you'll get about it because, in the spirit of breaking my habit of writing overly long articles, today we have to first take a trip back in time and discuss the history of my gargantuan rosebush landscape-origin/yardadori prebonsai. It has perhaps the largest trunk rose I've seen in the bonsai world (not that they're a common bonsai subject to begin with!).
