Canna ~2013~

While talking about water loving cannas,is it just canna grown from seed? ive just read that water can rot a rhizome so would they have to grown from seed every yr ?
and then 2nd yr plant the rhizomes in a bog area?or would that rot them aswell?
sorry too many questions

 

No joolz at the end of September pull them out and store like every other canna
one of the most pretty water canna is still the canna stuttgart and that it`s only available from root cutting .....work the same with all the tropical plant
the water get cold the plant die .

I will stop reading up on google it just confuses me and stay here

 

That's the canna warsceweczii in now

 

Hello chums

What kind of minimum night temperatures are we looking for? At the moment, I'm getting around 10c or more. Is that ok?

 

Plants? Should be fine. That's all I aim to keep my conservatory at during the "plant raising" season, and we aren't there yet so its currently getting down to 6C some nights. My starting-off-Cannas are in Garage which is a bit warmer, but will need to move to conservatory once they need light. Had several in conservatory last year because they were bought in the Autumn,a nd I thought too small to over-Winter "stored", and they continued to grow during the Winter no problem (frost free during the rump of the Winter, but touching zero on one night, and 4C - 6C on plenty of nights)

Seed germinating? I reckon that's a bit low.

 

Seedlings...

 

If they are germinated I reckon they'll be fine. Bit warmer would help - bring them into the house for the nights if not too much faff ?

 

Hi Freddy, I germinate my seed at around 25-28 degrees and then once they are around an inch high I move them on to a light warm windowsill that has a radiator below it that is on for 2 hours in the morning and evening, the average temperature in the windowsill I'm guessing is around 18-20 degrees, but it does get warmer when the sun is on it and probably down to around 15 degrees at night at a guess. Every seedling I've had on it, whether Cannas or other have thrived there and its no different now, this years sedlings are growing strongly.

In answer to your question I would say 10 degrees is a little low for seedlings, but as long as they're getting more warmth through the day they should be ok and I wouldn't worry too much

 

Hiya Kristen.

At the moment, they are in the heated propagator, in the greenhouse, under lighting. As you may be aware, I also have my 'monster' onions in there too, and to try to avoid 'leggy-ness', I'm trying to hold them back a bit, with regards to temperatures. It's a bit of a balancing act...

 

Thanks Bilbo

 

Well, I had an hour cleaning out the greenhouse today and checked over the several pots of cannas I had left in situ, letting them naturally dry out and I wrapped the pots in bubblewrap and fleece and packed some straw in the top of the pots.

After cutting back the remaining growth from last year I carefully scraped back some of the compost and found nice firm, fat rhizomes and some immature new shoots in every pot (8 in total, 5 varities), so no losses this winter as long as they all start in to growth this spring

 

Top one bilbo i have yet to go through that worrying process
I did a head count today i now have 61 growing (15 varieties) i so hope we have a warm spring cos i feel im going to need one

 

I'll be potting up my rhizomes in about a week just 5 plants 2 types. What on earth do you do with 61 cannas Joolz That's a lot of big plants !

 

Dont know harry ,i will plant and pot them i suppose where i can,back gardens pretty big and ive not planted much out front yet.
Someone on here must have more than 60 xx
