Here is a situation that has me puzzled and I am asking around to see if there are any answers.
1. Involves the same genus - Hoya.
2. Involves two countries: Australia and USA (Hawaii)
Problem: Cuttings from one of the country's growers root immediately after a long distance trip. The other growers' cuttings almost never root (not anyone in the usual thread of suppliers...just a little choice grower around here). This has been going on for years...and I cannot figure out why.
Both growers have beautiful plants. Both growers fertilize regularly and water as should be.
What would be the cause of the difference in the ability to root?
i have been getting a large amount cuttings from my neighbors some grow some don't, everythings supper clean new soil new flats.last week I was watering cuttings after watering noticed that i watered with RO water, three days later new growth on all cuttinds and both pineapple tops in water clean out the old tap water refilled with RO water roots everywhere.after three day and no mold.
Australia is N. Queensland with a definite wet and dry seasons. The other grower is on the E. side of the island... Nah, I think it is nutritional. Calcium for cell structure...Phos. a good possibility too... HMMM
I have a number of conundrums, Dave...you are welcome to any of them!!!! lol
I don't know that temps and rainfall have that much to do with the ability of a plant's cuttings to root. I talked with the PhD in plant pathology today and he hadn't a clue!!! Talked with a local guy (also UofH) who is a plant pathologist and also an orchid grower and he felt it was more nutritional on the part of the mother plant. I, actually, have had better rooting success with almost anyplant I root...even my own...grown in the same environment!
I know this sounds kind of silly...but I also know that it has a basis in truth: Perhaps the cuttings were taken at different phases of the moon. Some efficacious, and some not so much. Just throwing out my 2 ruppia.
Laugh if you wish, but it works!
Dave, I have a few extra conundrums and an enigma or two I would be happy to send your way...let me know.
Are you kidding??? Just look at them with a particular gleam in your eye, and off they go! Some get so big that you would swear that they were grown in a quandry! Best thing ever for growing labyrinths and cryptograms though.
I empathize Carol...it is tough keeping those critters around! Hanging some military weed or govormentus beaurocratis does help somewhat. My oxymrons are always out playing with the anacronyms from next door. I must admit though that I hadn't thought to use them on the quandry! Great idea!
Well Carol, I find if you take your quandry to the dry humour cleaners things turn out much better.
Wayne and I find that temperature makes a huge difference when we do cuttings. Our best cutting time is late spring when there is more light, a little humidity, and still fairly cool. 80's day time 60's night time.
Carol, try a bubbler on the cutting and see if it does anything...
put cutting in cup, then a small aquarium pump with the hose in the water...delivers o2...have had some success using this in the past.
I think I have been told the answer...or close to it. This came from one of the Extension Agents who deals with the cut flower industry...
Carbohydrates are built up in the plant as a part of photosynthesis... When a cutting is made, the carbs/hormones rush down the cutting to store at the node at the bottom of the cut (where the roots will be formed) and at the cut end of the mother plant to make new growth. When a plant is cut consistently and often, the mother plant is depleated of carbohydrates...and she cannot 'do her job'. The solution is to give that plant a rest...months to a year...to build up the supply of carbohydrates.
In our 'situation', the grower in Austrailia was coming off summer and the plants were slowing down growth. There is a good concentration of carbohydrates.
Dave... a further question to this question: By increasing the IMO in the soil to raise the 'brix' of vegetables, I add Molassas in water with Fish Fert or Chicken Poop. Raising the brix is raising the sugar content, right? So would that same process raise the carbs in the plants?
Hi Carol, plants take Carbon, Hydrogen, and Oxygen from air and water and manufacture carbohydrates. They are convenient little factories, producing 10 times more carbs than they need to survive; this allows us to eat!
I don't know that adding carbs to the soil would increase carb production in a plant though. Molasses provides a good source of potassium, iron, and calcium for plants. The carbs might stimulate bacteria and mycorrhizae in the soil, which would help the plant.
HAHA...I was running around worried about all the 'white fuzzy mold' in my vegie bed when someone told me people kill for that sort of thing!!! Shudda thought of that...as the vegies grow like gangbusters!!! I think maybe I will try it anyone...on two plants: one with/one without.
Little late coming in (what's new - LOL) fascinating conversation though...would love to hear how that experiment goes, Carol. God knows I have enough fish emulsion and black strap molasses sitting on my counter...part of that witches brew cocktail the plant enjoy...
