Just cover them with an old sheet or blanket (not plastic). They will all tolerate a light frost if in the ground but in containers it gets a bit more risky since they would get exposed from above and below (under the deck) both. I'd set them on one blanket and drape another over a deck chair or suck to make a tent for them. Dave

A rare plant so likely few experienced folks. You might check over on the Bamboo Forum here. I bet some of the folks there could better advise you. Dave Here is a link that might be useful: Bamboo Forum

seedlings do not grow steadily throughout their growth cycle - they grow in fits and starts (Like children).....and can often spend weeks in a minuscule state (lisianthus and browallia are dreadful for remaining minute seemingly forever) while others wait 2-3 weeks then romp away. In general, they will put on a growth spurt when transplanted (although again, they can stand still for a couple of weeks till they get over the transplant shock). Campanulas are also pretty notorious for staying titchy for weeks and weeks then bursting into growth. You have done the hard work (germinating them) so just sit back and let nature run it's course. As long as they are not actually yellowing, damping off, shrivelling, they will be fine - they have an innate growth speed determined by genetics as much as climate and conditions.....I have found that lights and heat have little significant difference in the time it takes for them to 'take off' and grow away......but grow away they will. 6-8 weeks is nothing - I have been waiting on some of mine since autumn, when they easily sprouted and have simply sat, for months, looking tiny (meconops, linum arboreum, eupatorium......while some are just emerging now (echies, primula wilsonii) but when they decide to put on a spurt, be ready for pricking out and potting on. Thinning, if thickly sown, is also a good idea.

I must say , years back when considering various palms to try indoors from a specialist palm nursery I'd order from in Florida, I was looking for some that would develope a nice trunk at a young age , but still not be too tall for my low ceilings at a young age, and I did sort of find a couple of those, though the "girths" aren't anywhere near what mature ones would have of course. On the other hand my Chinese fan palm only grew at the base for many years as the base increased in diamter over that time, til finally it started to show the "true" trunk with a diameter of six or eight inches, but still only perhaps eight to ten inches of true trunk below the crown shaft. I think many of the other plams tend to be "slow" in showing a trunk as well, though the crownshaft and of course the fronds are very lovely long before the trunks are formed!! The topic does remind me of the question, "Where does that crownshaft end technically , to become the trunk below? I think by definition the crowshaft for most varieties is the area extending from the lowest leaves on the trunk, to the top, but then of course those "lowest" leaves on some varieties that don't shed the old fronds naturally without some help, may extend all the way to the base of the palm , and I'm sure there's a true trunk under those dead fronds , if you get my meaning?? I see doing a little more research, the term "crownshaft" is used to apply to the way the leaf bases wrap around the trunk from the oldest fronds in the case of pinnate palms "only" I guess, so I'm not sure what the crown is called in the case of fan type palms or is that just plain "crown"?? Clearly there's a lot to be learned in the world of palms for me, when it just comes to understanding the specialized terms , when describing them in general!
