Overwintering Cyperus papyrus “King Tut”

Overwintering Cyperus papyrus “King Tut”

Cyperus Papyrus “King Tut” is only hardy to a bit below freezing and even that only for a short time. After first frost that did no damage to it, I decided to take a division and take it into protected place in the basement.

If grown from seed, it doesn’t get large enough the first growing season and I really need to save it. This summer it grew a lot, even with a lot lower temperatures than usual with abundance of rain. I saved some seeds, just in case I end up losing the mature plant. Some say, that with a lot of protection, Papyrus can handle the winter if it gets protected from freezing temperatures. I intend to keep most of it outside, covered with layer of dry grass, branches and straw, and large sheet of PVC above that to insulate the roots from winter cold as much as possible. If it can survive the winter outside, I’ll have one less plant to worry about next winter.

Overwintering Cyperus Papyrus Rhizomes are thick and hard to break using a shovel, so I had quite an exercise getting it out of the waterlogged soil. I dragged it into the large plastic container without drainage holes. I used concrete mixing tub – it’s strong enough so it won’t break when filled with water and large enough to accommodate the division. Hopefully I didn’t damage the roots too much in the process.

Arundo donax – Versicolor

Arundo donax – Versicolor

August 22, 2014 tarzan Comments 0 Comment

Arundo donax is tall perennial cane that grows up to 6 m tall, but can grow even taller in optimal conditions with enough moisture and as much sun as possible. It grows in all kinds of soil types, can tolerate dry and wet soil, withstands polluted waste water contaminated soil and soil salinity.

Arundo donax “Versicolor” is a bit smaller, less aggressive version with striped leaves. It’s a bit less cold hardy and lacks original Arundo’s vigor, but in temperate climate, cold hardiness doesn’t really count as long as underground rhizomes survive the winter. In warm climates without freezing temperatures, canes remain green and stop growing at low temperatures. When spring arrives with warmer weather, canes start growing again, pushing out branches from original stem. In colder climate, everything above ground turns brown, but the canes usually survive and can also branch out in the spring. Usually all the canes are removed during the late winter or early spring, because fresh growth looks much more attractive.

Trinidad Moruga Scorpion Chili

Trinidad Moruga Scorpion Chili

Trinidad moruga scorpion (Capsicum chinense) is one of the hottest chili peppers in the world. I’m not sure if I want to taste it, but it’s nice to have such a powerful plant around.
It originates from Trinidad and Tobago. In warm places without freezing temperatures during the winter, it can grow as perennial, but even the lightest frost can completely kill it, so it’s usually acting as an annual plant in temperate climate. Perhaps I’ll try to place it into large pot during autumn and winter and try to keep it alive during the cold part of the year.

Chili was growing slow at first, but got quite vigorous when sun got a bit higher in the late spring. It liked baking in full sun at high temperature, but it also needed a lot of water. I’ve made a mistake and kept it inside the same pot for too long, which resulted in strong and a bit congested root system. When I planted it outside, it took quite some time to actually start growing again – I’m not sure if it was low temperature and excessive rainfall or the fact that it got root bound while still inside it’s pot.

When it started growing again, it soon set up a couple of blossoms, which were pollinated and first fruits started to develop. Trinidad moruga chili has very small flowers, compared to other chilies I’ve tried growing, but in the end, chilies were not small at all. They seem to flower in waves, just as first fruits are starting to turn red, the next wave of small flowers started to emerge. Sadly this summer is one of the coldest and it’s constantly wet, which means that chili didn’t have the best growing conditions, but it seems the second batch of flowers should ripe before cold weather kicks in.

I decided to try growing Eucalyptus gunii and Eucalyptus globulus. The first is supposed to be hardy enough to survive our winters and will eventually go out. Eucalyptus globulus gets damaged when exposed to even moderate frost which makes it an indoor plant. I’ll try it inside for a couple of years and then if it gets too large, I’ll try it outside, perhaps with some luck and winter protection, it might regrow from the bottom of the trunk and roots each spring.

With enough sun and heat, eucalyptus can grow astoundingly fast. I was especially surprised with E. globulus growth speed. In only a couple of months it became little tree with thick and strong stem. E. gunii grew just as fast, but it behaved more like a wine, main stem remained thin and weak. I used bamboo to make it grow upwards and it worked.

Wet and cool weather made E. gunii suffer and after a while, it got severe mold infection. I removed leaves that were hit the most and placed it inside into dry unheated room to recover. Lack of light didn’t seem to harm them and they remained practically the same for a while. Dry air caused the mould infection to disappear, but soon they got hit by aphids. Especially Eucalyptus globulus started growing actively as soon as it received more light and warmth in an upcoming spring. When there were no more temperatures below freezing, I placed them outside in full sun and they instantly took off.

Even in small container, they both grew vigorously. Eucalyptus globulus looked extremely healthy and managed to dry out the pot two times in the same day in hot sunny weather. Since Eucalyptus is quite resistant to drought, they didn’t mind. Keeping it in a bucket filled with water kept them moist for a while, so they could continue growing throughout the spring and early summer. During the summer, I decided to plant them outside in the garden and try their luck in winter weather. E. gunii should be more than capable to withstand our winters, which is not true for E. globulus.

More to come as this little project evolves..
