Don't know about Poinsettia plants but thought I would add don't forget to fertilize
Sounds like you're doing just right. When in bloom and in a pot indoors, they need careful care. Only just enough water every other day and no drafts, otherwise, they get moldy and drop flower pieces.
I am watering every 3 - 4 days at the moment, just when the soil dries out a bit.
Th bought ones usually has been treated to short daylight and they are treated to keep them compact. I have got them to flower again the next year but the plants were not as compact as the original ones - the bits of stem between the leaves were considerably longer.
The Videos I have seen, cut the stems down to a certain point. Out of 6 stems, I have cut down 3. It will be interesting to see if they sprout new growth. All a bit hit and miss. 😁
Here in Sydney I planted mine from last year into a large pot out the back it gets the morning to mid day light and it is the most glorious red. With daylight savings started here I may have to cover it closer to Christmas.
If this trick does not work I will also probably do the same.
In a few weeks I will let you know if it had worked. I find it very odd that it is a Christmas plant both in northern and Southern Hemisphere. I think it originally comes from South America
Poinsettias hale from Mexico, Middle and South America. It is a short-day-plant. Hugs
Hi Sarah, I don't know about a dark place, but here where we live, a friend and myself walk and there is a very large poinsettia growing in someone's yard along the way and is in full bloom now. This is in full sun and not in a dark place and doesn't seem to be getting any special treatment. Hugs Maureen in Durban
The road behind us has a poinsettia tree. Every year it has the red bracts. It is not doing so well at the moment as we have had a month of strong winds
They are very sensitive to the day length. When grown commercially it is controlled very carefully to bring them into colour ready for Christmas.
The "flowers" are actually coloured leaves (bracts) so perhaps your cupboard is doing the trick!
I have read so much on Google but it is all information from northern hemisphere. Our shops are full of poinsettias at Christmas time so it really does not make sense. I am just really trying it out. My plant is sprouting masses of new leaves so if I get no red ones it is still a nice plant.
