Amorphophallus-Forum.de

I have long cultivated Amorphophallus time unsuccessfully. Had always an only a few-week growing season and the tubers were getting smaller or formed from no bulb, so I had knollenlose plants which have entered. I've tried many.
I had them on the window sill, where the hand strongly vergeilte. I had them at the East window are, because when my window is a large oak tree and a chestnut tree, where it is quite dark in the summer by the shadow.
For 2.5 years I care slightly more successful a new brood nodules, which was time 1 cm long. I said to myself with these nodules, you must learn to succeed. I've put the small nodules then end of April on the lighter balcony shortly after it had expelled. The sheet was not yet unfolded, so got no sunburn. I have fertilized it neatly and in autumn, she had made a triple major tuber, she then had a diameter of 2.5 cm. For me, that was a reason to cheer.

The summer was cool and rainy. Last year the tuber drove out quite late in may, needed however two months because of the very cool weather on the balcony to unfold the sheet. The leaf moved again after a month, so the beginning of August. The last summer was even cooler than the previous, from May to September there was no sun but only rain. There was only a summer's day in August, where just the thermometer for a day rose to 26 ° C. I live in the Harburg Mountains, where it is cooler and Rainier than in downtown Hamburg. My Amorphophallus had formed a new bulb but after three months of vegetation has grown but not, but slightly smaller than the old one. The old tuber has been preserved. This year the tuber mid-April began to drift. The first weekend were somewhat mild and sunny, so I out put them on the balcony so that she do not fast. But until now, still no sheet shows. The drive is growing extremely slowly. He catches just to pierce the surface of the Earth. The Kolle is about 2.5 cm deep in the soil. The drive is only about 2mm in one month, I fear that this year again is nothing if the weather like last year is twice as cool. At the time, is very cold and rainy.
I was last year in October in Bern/Switzerland, where I saw Amorphopallus konjac in tubs, the end of October not indented and the sheet was still beautifully green. In the Switzerland, the weather had been better and much warmer and sunnier as still very summery cool Hamburg and in October.

I have found already in vain konjac wanted, unfortunately only reports on the Internet according to care instructions for Amorphophallus, where people show proud their plants with enormous tuber growth. But apparently, they make a secret of the fact how they get this concluded.

Rather, I have the problem to have at all a tuber growth. Often, the plant grows only a few weeks. I'm assuming that it has to do with the sunshine and cool weather conditions.
Can you move the plant earlier than may to drive by earlier sets the tuber in the damp earth and then very hot is? My plant is constantly only at the stage of tubers and several months, i.e. vegetation time is 3 months and 9 months she rests.

I would highlight in addition in my residential area because of the darkness in early spring and the often sunless days so that they do not vergeilen. Then, it is difficult to get used to these plants to the Sun, if times summer will be times summer because room burn then easily plants driven from in the summer.
In this way previously all Amorphophallus entered me, because they were then even tubers and the old bulb was rotten.
How big must the pot in proportion to the size of the tubers be selected. I sometimes think that the pot was too large. I could not often be able to fertilize my plants because the Earth was barely dry. Apart, it rains here all the time and flushes away the fertiliser. To you by grow seedlings with artificial lighting and heat, so that the tuber times finally grows and not less! Would a room culture with additional lighting on the East or West window then make more sense because of the cool and wet weather?

I had planted the plant a mixture of Sphagnum, Kokushum and pine bark and on fertilised. The roots were always very well developed and strong. The whole pot was greatly durchwurzelt. I have observed that very large pots adversely affects the formation of tubers, because the fertilizer is more diluted than in the smaller pots at some caudexbildenden plants. Strong root growth certainly know on a nutrient deficiency and although I manured with every watering. Due to the many rain I could hardly casting and thus fertilizing, otherwise the plants were rotten. At the time I have taken my Amorphophallus again from the balcony and in the warm room heating, in the hope that the sheet then faster drives.
When the substrates, I will peruse me times. In the meantime I have already noted the phosphorus-containing Depot fertilizer, tuberous growth is conducive for that. Now it comes me, to extend the growing season. I think that cool temperatures suggest a fall plants or retard growth in the spring. The plants grew better in warm years.

Greetings Wolfgang

Meanwhile, a drive which is about 2 cm long evident in me. 3 More thinner shoots come from the lower bulb of the penultimate year. Today I put it on the balcony in the Sun. What are your konjacs? To you by grow smaller plants without rest? Exorcise the plants sooner, keeping it moist and warmer?
