Trying to save satin pothos cuttings - any advice?

I took cuttings from a satin pothos about 3 weeks ago. Tried some in water and some in soil.
First pic in water has rooted, was waiting for an inch but now top of roots going black. Not mushy though- could I scrape black off and pot up or are they diseased/ root rotten?

Two of the cuttings in water (middle) have done no rooting at all, but one of the two seems happy and produced two new leaves.

Soil ones (think last pic?) are v curly but roots seem to have taken hold and new growth on top of one? See pics. Should I now repot to bigger?

Hoping to save something and would love to make mother plant more bushy but dont want to contaminate.... would love help! Thanks x

 

For many of what we might call 'exotic or tropical' vines/plants that produce these arial roots. Either layering or arial propagation proves to be the best.

Growing such plants, providing a moss pole is most beneficial. Using such, the arial roots penetrate the moss and can gain a degree of moisture and also maintane support.

 

Thanks Mike , but am not sure how that relates to my question about the cuttings?

 

Looking at the one rooted in the pot, it appears fine, leaves of Scindapsus (Pothos) do sometimes curl. The Size of pot looks ok to me and will probably not have enough roots to need a bigger one this year.
It can be trained upward or left to trail.
The water rooted ones still look ok just changing colour as they mature. You could pot these on now but personally I would put the pot in a plastic bag to retain moisture and out of direct sunlight but opening the bag for an hour or so each day.

 

Hello Alex. I have grown Devils Ivy and propagated as per my previous text.

To cause the plant to bush out, and this applies to almost all plants. Simply pinch out the growing tips.
Regarding cuttings, and I quote from Dr. Hessayon's writings. Winter temp. 50-55 deg F. Well lit but sunless site. Water liberally from Spring -Autumn. Mist the leaves frequently. Repot if required in Spring/Summer. Take stem cuttings in Spring/Summer, use a rooting mixture. Keep the compost dry and place in the dark until rooting has taken place. End of quote.

Point of interest. This plant and similar vine-like plants having these arial roots. Whereas in many climbing plants where they may have tendrils. Tendrils are used as a natural means by which the plant can cling onto something. Whereas arial roots actually are used as roots. Roots draw up nourishment Despite being called arial roots and having the above function, most of these plants in their natural habitat will often grow prostrate. Here these roots will aid the additional feeding.

Perhaps it's strange to place cutting etc in the dark. Basically this reduces, almost eliminates the plant's need to concentrate on uv rays to cause the photosynthesis/sugars etc. So what is remaing within the body of the cutting is used 100% to the formation of roots.

Hope this helps.

 

Thanks for this. That's all really clear.
The potted in soil ones are in quite a small plastic pot and it tends to hold the water, maybe I could wait till I have more roots on my water ones and put some of them in a slightly larger terracotta pot?
And glad that you think those roots in water are ok and not rotted.

 

Hi Mike
Thanks for all this, so very helpful. I didn't understand your earlier email but have looked up the world of layering - very interesting if slightly scary for a novice! I will definitely try a moss pole in my satin pothos.
Pinching out the tips will make the plant bushier? I will give it a try. Thanks for bearing with me. I'm new to all this and so love this particular plant.
