Variegated Bamboo Seedlings – Summer 2017 Update

Running, at last!

Running, at last!

Keeping my 3 variegated Phyllostachys arcana ‘Luteosulcata’ seedlings inside during last winter, caused seedlings to decline. The older seedling that was once larger, hardly managed to survive the winter. At first, they seemed healthy, but they all got some kind of mold infection soon, which didn’t have any visible effect on their vigor, yet they started to decline as they stayed inside for too long. When I planted them outside, their leaves recovered and mold issues stopped, but they refused to start shooting.

A few words about the weather

This year we’ve had a cold spring with severe late freezes. Cold did not harm the variegated seedlings, but the infected moldy leaves fell down. I suspect the much brighter sun fried them completely. New leaves were healthy until later in the summer. Summer brought very warm weather without much precipitation. Temperatures rose up above 38°C a few times and stayed above 30°C almost the whole summer. I planted the seedlings into raised bed, which made them suffer drought a bit more, despite frequent watering.

Heat stress resilience

During first half of the summer, all the seedlings managed to cope direct sun exposure extremely well. I expected the two highly variegated seedlings to have issues with bright light conditions, because I’ve seen last year how their leaves tend to bleach due to sun exposure. Until mid June, there was no damage on any of their leaves. They looked fascinating, despite the fact that they never started shooting and all the leaves and branches were the result of growth that was initiated inside. As summer progressed and sun reached the highest point in the sky, leaves of both bright variegated bamboo seedlings started getting bleached. The strength of the sun was just too much for them to handle. At the same time, we’ve had temperatures above 35°C, which only added some additional stress to the plants. The leaves of all the seedlings curled during the heat and watering didn’t help much. They were not able to supply enough water to replenish the water lost due to transpiration. Over all, heat and sun related resilience was good. I am impressed.

Drought stress

In mid summer when the heat was hardly bearable, drought kicked in. Constant wind and very high temperatures started to show first signs of damage on the leaves. Daily watering was not enough to keep the soil wet, but even when the soil dried out, bamboo seedlings got enough water from deeper roots. When the seedlings mature, I expect them to fare drought even more. In the end of the summer, leaf tips stopped drying. At the same time I noticed they were not sitting idle during the summer. They were producing, a lot!

The darker green variegated seedling that was the largest and nicely variegated while I kept it inside, had lost the variegation almost completely. It looks like bright light position makes it greener and shady indoors conditions under grow light caused it to become variegated. I may try moving it into a shaded position or I’ll just divide it and plant it into different locations. It is the only seedling that did not start shooting until late August. There’s one more thing I need to mention about this Phyllostachys arcana seedling – it did not grow any taller. Now it looks like some kind of ground cover bamboo with many tiny culms that only reach 20 cm or so. It all happened when I watered it with an Aspirin solution as I experimented with salicylic acid to combat mold infection. Possible cause could also be the lack of dormancy. I’m quite certain it will start growing next year.

Running!

As the summer fell into second half in early August, I have noticed that two highly variegated seedlings started running. Runners started crawling in all directions, often getting to the surface and plunging back into soil again. The seedlings are still small and the rhizomes are also tiny, but the fact that they started spreading with such vigor is very promising. It will be interesting to see them start shooting the next spring when they hopefully start upsizing exponentially.

Winter is coming… eventually

When the warm part of the year ends, I plan to keep them outside in my raised beds. I will cover them with PVC tunnel and hopefully they will like it as much as a couple of tiny all-green seedlings last year did. They are now spreading vigorously, producing quite thick runners. I’ll somehow get rid of those in the spring, to make room for the variegated seedlings. I expect them all to recover even further after they get through their first dormancy.

Ducks in my garden

Slug control

Like most gardeners in temperate climate, we have a lot of slugs roaming around, devouring tender vegetables and flowers. Slug repellents don’t really work, which means the only environment friendly option was, to find a slug eating predator. One of the best (if not the best) creatures that feeds on slugs are ducks. I got several Indian runner duck eggs, bought cheap Chinese made egg incubator an hoped I can make them hatch.

Incubation

First duck egg externally pipped!

Duck eggs are rather easy to incubate. It takes a bit longer for them to hatch, compared to chickens. Optimal conditions to incubate duck eggs are 37.8°C at 55% to 65% humidity during first 12 days. Then, humidity needs to be increased up to 60-70% until day 24. All that time, eggs need to be turned at least 3 times daily. From day 25, eggs should not be turned and incubator should remain closed. Humidity should stay above 80% and temperature set a bit lower to 37.4°C. At that point, internal pip occurs which means the ducklings break the internal egg membrane and start breathing air from the air cell. When they pip externally – they break through the egg shell, humidity must remain high. If humidity drops, internal membrane can dry out and entangle the small duckling. As it can’t remove the dry rubbery membrane, it usually dies without proper assistance.

Success!

I never tried incubating eggs of any kind before and decided to buy cheap-ass incubator without humidity sensors. I had very low expectations and planned on buying ducks when I finally fail with the incubation project. Luckily I didn’t fail. I learned a few lessons during that month. The first one was around day 7, when I threw out an egg that was developing completely OK. It happened that I couldn’t see the embryo properly when I candled the eggs and I decided to make some room for other eggs. Later on, I bought external humidity sensor and tried to get egg cell large enough. I failed with one egg, and got two all the through. The second one hatched on day 30 and had yolk sack infection. Duckling died in a few days. The first one was healthy as young duckling can be.

Brooder

I bought infrared heater lamp and used an old cardboard box to make a brooder. Since there was only one duckling inside, I didn’t have much issues with droppings and spilled water. I thought I did, at the time, but later I found out what multiple ducklings are capable of. Nasty. I gave it chicken starter feed and any insect I could find around the house in the spring. Young ducklings have extreme appetite and they grow very fast. At the end of second week, it got warm enough for the duckling to go out and roam around freely. It didn’t search for food much and avoided the pond, but it loved being outside. It imprinted on me a lot, so I decided I need to get a few more ducks, so it gets proper feathery company. I bought 3 ducklings that were the same age, but they were all small, had leg issues, missed feathers and shown nutrition deficiencies. I placed them all outside into their duck house, because temperatures outside got cozy enough for them to remain outdoors.

2 of the maltreated ducklings died during first week, both suffocated, because they were not used to have enough food and they never drank water when eating. The third sickly duckling remained alive and started growing insanely fast. It gained a lot of weight as well and started having even more leg related issues. I started giving them more yeast to increase niacin intake (vitamin B3), but it only got worse. Later I figured out it was just gaining size and weight too fast for its legs to keep up. As both ducklings started showing signs that they are males, I needed female ducks. I can always replace one drake with a female if there’s problem when they start mating. The seller of three sickly ducklings offered me 3 replacement ducks (at that point the remaining duckling wasn’t able to walk at all and I was certain it will perish as well). Luckily, all three were females! Now I have five ducks, one beautiful, large drake I incubated, one fat and lazy drake and 3 small lady ducks. Hope they will remain living in harmony when they reach sexual maturity in a month or two.

Borinda fungosa winter damage 2016/2017

This winter was quite brutal. Temperatures did not plunge lower than normal, but it got cold enough for the soil to completely freeze down to 0.5m and even deeper. With no snow cover to protect the delicate Borinda leaves, it stood little chance to survive the winter.

The cause

Top killed Borinda fungosa

Top killed Borinda fungosa

During early winter, there was no visible damage on any of my bamboos, even Borinda fungosa (gaolinensis?) fared much better than I expected. But then came a period when we received no snow, only freezing temperatures that remained below freezing even during the day. Combined with cold north eastern winds, soil cooled off considerably and it froze much deeper than usual. It remained frozen for quite some time, even when temperatures rose above freezing.

The damage

When temperatures got back to normal and after some “warm” rain, leaves lost their green color and it became evident that bamboo ended up completely top killed. Culms were all noticeably bleached, green culms had the darker green, somewhat watery appearance. At that point, I was sorry I didn’t tarp the bamboo and try my best to protect it. It all seems now, that no protection could have save it this winter – the weather was just too much for a marginal bamboo like Borinda to survive intact.

The awakening

There is still some life in it...

There is still some life in it…

In early spring, we’ve had a period of extremely warm weather which had awaken all the bamboos, including the badly damaged Borinda fungosa. I have completely removed the dried out culms and I soon noticed a couple of survival shoots, pushing out from the base of dead culms. Until now, there are no regular shoots that would prove that the bamboo is going to recover. I hope there are healthy rhizomes with undamaged rhizome buds below ground. Usually the first shoots appeared around mid May, hopefully they will push out this year as well.

The conclusion

Some small survival shoots started to emerge

Some small survival shoots started to emerge

Borinda fungosa I’ve been growing from seed for 6 years somehow managed to thrive in this marginal climate. It got damaged during the winter and didn’t like the heat in the summer, but it managed to grow and upsize into a very decent bamboo. This winter was not typical for us. At least not statistically. It’s sad that the same climate pattern started to repeat itself almost every year. Almost no winter precipitation, cool northern wind and sunny weather can dry out even more winter hardy bamboos. As if the winter was not bad enough, we were recently hit by a nasty late spring freeze. My Borinda doesn’t have the best growing conditions in my garden. It may perish in a year or two even if it survived this winter.

Blueberry seedlings update

Two years old seedlings

2 years old blueberry seedling during late winter

Two years ago, I have started growing blueberries from seeds. I have collected some of the seeds from large healthy fruits on my old blueberry plants. After stratification, seeds germinated very well and I ended up with many tiny slow growing blueberry seedlings. I have waited two years, before planting them into their final location and I have kept them in a rather small container in peat without any additional fertilizer. They could be a lot happier if i’d give them some food earlier, but they managed to grow anyway. When I planted them into mound of peat outside last year, they immediately started growing large shoots (compared to existing growth). In autumn, it became evident, that most of the seedling set up their first flower buds. Some failed to survive the weight of snow during the winter.

Third growing season

In early spring, buds started opening

In early spring, buds started opening.

In early spring, the buds started swelling and I noticed they will start even more vigorous than last year. All the 1 year old shoots started leafing out early with nice red colored young leaves. All the shoots were extremely healthy and small seedlings soon began to look like nice little bushes. Some of the shoots have already started flowering. Flowers and leaves seem to be similar to their parent plants, but there is one plant with slightly different flowers. One of the seedlings have flowers which have much smaller opening of the flower. Despite being tighter and possibly harder for the pollinators to pollinate the flowers, there did not seem to be any issues regarding pollination.

FIRST FLOWERING

I didn’t expect them to start flowering so early, as they are not taller than 30 cm with shoots just a few mm thick. At first, when flower buds opened, flowers appeared to be small and perhaps even a bit distorted with stigma pointing out of developing petals. Later, flowers developed normally and the seedlings started flowering at the same time as their parents. It will be interesting to see their fruits when they ripen. Plant appearance is roughly identical to their parents so I’d guess the fruits will be the same  as well.
