Wow, theyre the same age? How much has the light got to do with it, and how much the fert? Very impressive difference!

hmm, must think about this.

Yours is much younger I suppose. Why is it stretched> Is that the effect of the fertilizer? Or do I have better light? btw. i'm just making a new one from a leaf and if I can keep it compact I think I prefer nonfertilizing. A lot of nurserys use fertiliser and produce nice plants. The effect, when I get one, that they shrivel under my regime and don't look so pretty anymore.

must think about this.

Interesting post!!

greets harry

Dave and Harry

i have one that looks just like Dave's, grown under natural light here in Nova Scotia and indoors for winter. Fertilized somewhat regularly with dilute Foliage-Pro. No pictures at moment as it is outside in the mini greenhouse chaos in the rain ( everything got moved out yesterday, but not very organized yet!)

If I had one, it would likely stretched like Dave's.

I would prefer Harry's look. I think it may be Harry's way of growing - overwintering with very little watering, in cooler temps - isn't that what you mentioned Harry? And also not fertilizing during that time especially...my belief is that it will encourage them to grow rather than rest, during darker and colder months? - causing even more etiolation.

The leaves are even shaped different. Are you sure it's the same plant?

I also a prefer the look of Harry's plant. Mine gets quite a bit of light in winter, but it is also quite warm as it over winters in my living room in my big window which is unfortunately over a baseboard heater. So I must water it or it shrivels. Next winter I may put it under artificial light to see if that helps..

Beth, I keep them under lights...but unless I had top-notch lighting system as Kevin has, there is still some etiolation.

Rina,

That is interesting. How warm di you keep them overwinter? What kind of lights do you use, and how close are your plants?

I don't think it is etiolation, since the sun here at 5000 ft in Nv.is considerably more intense than at sea level. Mine has been outdoors for two months in all day sun, so I am assuming that effect is entirely from fertilizing and very occasional watering-it goes completely dry between drenchings. Again, the light here, even in winter is so intense that even indoors nothing goes dormant, or really even slows down.

This sedum is extremely heliotropic, it needs to be rotated every day to prevent leaning.

Temps indoors in winter are usually about 55, anything warmer is strictly from solarisation, night temps are generally about 50 or a little cooler.

Dave

I would be happy to hear it is not etiolation. I have plant that looks similar (not the same plant). I don't think it was fertilized even once.

Beth

I have 'only' t8 fluoro tubes and many CFL bulbs (IIRC, Kevin is using T5HO, temps are bit higher and he waters and fertilize more often). Plants are only inches away - many as close as 2". Temps this winter were around 16*C (60*F)

Harry

Thank you for the photos and post, that is what I was referring to - your plants are kept dormant rather than warm, fertilized and watered often to keep growing during the winter.

Incredible setup Harry, what a plantsman you are.

Where I live we are at an altitude of a little less than a mile, temperature zone 7a-cool but seldom really cold. Humidity is very low, this year in Jan. it went under 10% for a couple of weeks, the air is very clear so the sun is very intense.

This year I started putting plants out in march and have already had some problems with sunburn, so need to move things around to the north facing decks.

I think I'll start a new sedum and try growing it very lean with no fertilizing and in a year or so we can compare results. ;-)

Pictures of treleasei in it's natural habitat are like your plant-so fertilizer is causing unnatural look of mine.
