Variegated Phylostachys arcana seedlings – Summer 2018 update

Second seedling looks extremely well at this point, and the best part of the year is still in front of it

Sunburn recovery

As I’ve mentioned recently, two heavily variegated seedlings are prone to sunburn damage. To correct the issue, I decided to plant some fast growing plants in front of one of the seedlings. As bamboo started branching out, the canopy started shading itself, which further helped the seedlings. Both seedlings started looking much better when days started getting shorter in late July. After wet and rainy start of the summer – well, not that spring would be any better, temperatures rose well above 30°C. Both bamboos resisted the heat and wind pretty well. Way better than strong sun exposure in late spring and early summer. There was some leaf curling, but not nearly as much as I’d expect. Actually, they didn’t curl as much as a non-variegated seedling next to them.

Culms coloring up

Regular green seedlings have dark green colored culms that turn dark brown if exposed to intense light. Variegated seedlings have much less green and can be almost completely yellow with some green striping. Culm variegation occurred on both seedlings. Most of the culms that were at least a bit exposed to sun started tanning up and turned out quite nice. The seedling with darker culms had more green variegation and turned light brown. The first seedling has much paler culms that are almost completely yellow. There are some stripes involved, but they are hard to spot at the moment – the shoots were way smaller and the variegation much paler.

Rhizomes

I haven’t been digging dirt around the seedlings, but there is some serious rhizome activity below the soil level. I have seen them pushing the soil up and dolphining. Soil is also cracking due to underground bamboo growth. None of the highly variegated seedlings started shooting for the second time in the season (August 1st). The third seedling that is also variegated, but has dark green appearance, compared to yellow colored first two seedlings, started putting out second round of shoots when the rhizomes got above the soil level. All of them were nicely variegated.
