Phalaenopsis won't grow roots

[Raqsharqi]

I'd be happy with one root! The plant looks so pathetic now! I really don't want to lose this one!

This will seem self-serving, but get some KelpMax, and apply it at 1 tablespoon per gallon for three successive waterings. You'll see root branching and growth like never before.

When I first started using it in my own greenhouse, the average vandaceous plant went from producing about 4-6 new roots to about 40. Needless to say, that convinced me it was worthwhile, so I started carrying it.

Originally, the product was touted as being full of auxins, a few cytokinins, and a wide variety of amino acids and other nutrients - unique in the seaweed extract world, due to the lack-of-dame in their extraction and preservation. A recent study showed that, even in materials that had be stored for over two years, also contained abscisic acid, and concentrated gibberellins and brassinosteroids, which have been shown to elicit a wide range of physiological responses in plants, such as cell division, stem and root growth, flower and fruit development, seed yield and protection from stress.

I ordered some, Ray, but it won't get here until mid February. I hope the orchid lasts long enough to see if it works.

Wow, Ray, the KelpMax is here already! That's mighty quick shipping! I'll mix up a brew today and let you know as soon as those roots appear.

Ya ya! Keep me update! I just drench my b. cordata. It wasn't doing well and I'm trying to save it. . If it die, It's gonna eat me up bad. Wish you the best with phalaenopsis. One of my phal was rotten roots. I was like darn it... So I took the moss off and replace it with fresh moss. I cut down and watch how much I water it. There were like couple roots growing but very slow... Along with kelpmax, it helps...

Couple of points. I really don't like sphagnum. I suspect it of being a causative agent for rot and related problems in phals.. No evidence, just a hunch. I was told to pot them in plain large fir bark lumps, and all mine are spiking like crazy.

I have also read that shifting from one type of medium to another causes problems, the suggestion was that the plant almost has to grow a new set of roots to adapt to a different medium.

If I had a problem phal like this, my temptation would be to pot it up in bark ONLY, ensure that it was at optimum temperature and light, and spray it every couple of days so that the medium was humid, but very well aerated, and the centre of the plant had moisture running down it. I'd use a spray, and take a lot of time over the watering, rather than a quick in and out.

I'd also try and house it so that while it wasn't overly humid, it wasn't drying too quickly.

I'd use RO water and Ray's KLite, and an occcasional weak dose of kelp. I'd certainly also use his other stuff with the bio agents.
