Watering Baby Seedlings

Post by LouiseJB on 16th May 2017, 11:15

Hello,
I have a few of my first crosses coming up sporadically. I was wondering how much and how often others water them so they don't damp off? I've lost a couple with damping off and/or seed coats failed to fall off.
Any advice is gratefully received.
Thanks,
Louise.

A couple of things Louise,

How old are they
What are the crosses
What mix are they in

Misting is the better way if you can, you only need to keep the mix 'damp' not wet, when you mist you will see the mix change colour, just past that point
Can we see some photos please.

Hello,
My main concern is with those that are in the first two weeks of growth as what I understand that is when they are more susceptible to damping off. But I'll include my oldest one as well. Please take into account that these are seedlings from an experimental pollination last may. They did two months stratification from September to November and were placed in peat pellets in November. They were outside on a northern facing wall and were kept damp over what was a very hot summer. I am surprised I am getting any to germinate at all.

1. The youngest one is two days old and the oldest is 7 weeks.
2. In order of above they are Figurine x Falling in Love and Figurine x Ebb Tide.
3. The youngest one is still in a peat pellet and the oldest is in Searles Premium Peat 80B Potting mix.

Photos as follows:

Figurine x Ebb Tide

Figurine x Falling in Love

I've been using a hand held sprayer to keep them damp as mine is very much a manual system here. One day I'll get better organised.

Thanks again,
Louise.

Louise, they are looking good. I do like the Figurine x Ebb Tide cross, I will try and find a chart with the possible % of colour from your cross.

The Fig x FiL "should produce a pinf with what is in thier background and maybe a "floribunda/spray type flower"

Anything in a pot I would start to introduce them to the daylight of Qld, not direct hot sun, but warm sun, this is called hardening off. What temp range day/night ?

Once the ones in the jiffy pots get true leaves I woiuld transplant them. As for misting, I did mean a spray, not a complete misting system.

Our temps for the rest of the week is estimated to be between the low teens and low twenties. At what temps should I bring them inside?
Thanks for the colour prediction. How cool is that!
Cheers,
Louise.

To be honest Louise I would bring them in for the first week and then go from there, if you don't get below 10c it would be ok to leave them out after a month.

Hi David,
If you don't mind I have another question. I have another seedling coming up today and the cross is Figurine x Jude the Obscure. Yet another miniature seed germinating.I don't know if this is the norm but do miniature crosses germinate more readily and earlier than say larger roses? Or is it just a coincidence in my case? Or is Figurine a strong seed parent and produces viable embryos?
Thanks again, Louise.

Nice cross again Louise. Interesting question.I do not know the answer, but would assume luck and chance is my answer. I will ask some friends and get back to you.

Thanks David. The Figurine x Ebb Tide seedling has a bud on it. So We'll find out what colour is is in a few weeks. I'm very excited and I'll post a photo when it arrives.
Cheers,
Louise.

LouiseJB, you are getting to the exciting part of roses.
I am like an expectant father when seedlings are showing their first bloom. As they mature the blooms change, all these stages are very interesting.

I use a tub made from sheet metal tub, folded to accommodate the size of one to four 75mm high x 500mm long x 400mm wide plant crates. The crates can be lined with shade cloth to prevent loss of seedling mix. I find Osmocote seedling mix a good size for roses and citrus understock seed germination
Allow a 50mm space all round the plant crate so it can be inspected while adding water. If you are only germinating a few seeds then cut down height Polystyrene boxes without holes will accept quite a few pots. These pots can be used for germinating or putting out new seedlings as the mix is not disturbed by top watering.

Hope you can follow, sorry I don't have the nack of sending photo's from my computer but OK with mobile phone.

Good luck.

Thanks Ozeboy. It is an interesting journey this rose breeding caper. I pulled some seeds out of the fridge yesterday to find two had germinated. I had always thought that maybe I didn't leave them in long enough but this is the first time I've wrapped them in paper.
Cheers,
Louise.

I always wrap my seeds in wet/damp paper towels, then into small freezer bags.Some varieties show a 50% germination rate in the fridge. I have used 1/2 strength Fungercide to dampen the paper towels but gave that away as the seeds don't seem to get fungus at low temperatures.

The seeds that don't germinate until the second season usually get thrown out because of weed seeds that blow into the trays.

Go well and breed healthy roses.

Hi David and Ozeboy,
By the look of it my Figurine x Ebb Tide seedling is going to be white. It's guard leaves are starting to peel backwards and it looks to be a very light colour under them. So that fits with the colour prediction chart. Will post photos when it opens a bit more.
Cheers,
Louise.

Hi David,
You were right it is pink but unfortunately it is showing signs of proliferation. A bit disappointing as it does have some nice healthy growth. I've added some photos taken this morning.

On another note one of my other seedlings (Figurine x Jude the Obscure) are developing roots but not sending any true leaves out. Is there a time frame for them to do this? I probably know the answer to this question. It is called patience, right?

Cheers,
Louise.

Louise, do not worry about the profliferation, it might be due to a lot of influences, it can change as the plant gets older.
As for the Fig x JtO cross, yes the answer is patience, I think it is better that it is developing roots rather than the top, all plants need a good root system to survive, any chance of a shot of it Louise please.

Hi David,
Here's a photo of it. It does have a little of the seed coat left on it but it is too small for me to try and remove it. The second photo is of it on the right with two other germinations this week. They are both from the same cross Tineke x Flirtatious. They were the ones that germinated in the fridge and seem quite strong little plants.

I am now watering the seedlings from the bottom early every morning (as Ozeboy talked about) and haven't had any mould problems since.

Cheers and Thanks,
Louise.

Hi David,

Just an update. The Figurine x Jude The Obscure seedling is finally showing true leaves. Others that have made an appearance are Tineke x Flirtatious, Melinda Gainsford x PJPII, Red Pierre OPs and today a Mother and Daughter OP. They seem to be coming up sporadically and randomly. I'm just assuming the ones that germinate have the strongest embryos.

Cheers,
Louise.

Hi Louise,
" I'm just assuming the ones that germinate have the strongest embryos.| This is not always the case, if you were to go back in the parentage, it might show some form of "species" rose which germinate sporadically compared to some of the other crosses. If wil be nice to see the colours that come from the crosses. The other thing is the seed coat could be a little different on some.

Hi David,
This is the second flush on my Figurine x Ebb Tide seedling. There are four flowers at different stages. What starts out as magenta in colour fades to a pale pink. I don't think it is too bad for a first go and I am relieved there is no proliferation this time.
