Hi everyone. This is my first post here. I've learnt a lot from everyone's posts over the past few years. I've run into a problem and I was wondering if anyone has experienced something similar.
I've been trying to grow some tuberoses for the past 2 years. They got plenty of sun, plenty (but not too much) water, a small amount of fertilizer here and there. They start to send up the bloom stalk in August or September and grow normally, plenty of buds, stalks about 70-80cm high. But just as they seem to be about to bloom each and every one of them has displayed the same problem. A few inches below the buds, the stem begins to look bruised. Pretty quickly it starts to bend and drop down and then the buds dry out and die.
I have actually got bulbs from two different sources and they both display the same problem. They are both the single Mexican type tuberose. I've been bringing them inside in October once the weather gets cold and I had wondered if it was fluctuating temperatures causing this problem. This particular one in the photos however was brought inside in September, and left in the same position (a sunny south facing windowsill) since then. It has looked healthy until two days ago (I realise there are very few lower leaves on this one - but I don't think that's relevant because all the others had plenty of leaves).
I live in Ireland and outdoor temps right now are 9 or 10 degrees celcius, indoor temps about 16 during the day and getting higher in the evening when the heat comes on. Could it just be too cold for the plants?
Other than that, maybe it's some kind of disease? Has anyone seen something similar?
