WAMcCormick said:Does the soil you used have a high clay content? If it does, it can hold water like a jug.
Is the new soil the only part that is staying wet? If the original soil filled with roots is dry while the new soil is wet, then the composition of the new soil is not close enough to the composition of the soil in the root ball and may need to be redone to match better. If the root ball is dry, the moisture in the new soil is not moving to the roots, and the roots need water. Is that muddy enough?
Gina1960 said:I believe I replied to your Monstera post before. I've kind of specialized for the past over 35 years in growing tropical plants, mostly aroids, of which your Monstera and your 'elephant ear' (which is an Alocasia 'Poly') are a part of that group, aroids.
Many aroids are epiphytes (like your Monstera). Some are terrestrial (like your Alocasia).
But the one thing that they all have in common is that if you are trying to grow them as houseplants in pots, they need a very fast draining potting substrate.
Most plain bagged potting mixes, even Hoffmans Purely Organic, are too heavy.
They do NOT like a lot of PEAT which is one of the main ingredients in most bagged mixes. Peat holds water too long for them.
The best potting mixes for aroids are based on a scientifically researched formula developed by the Atlanta Botanical Gardens. This mix is, in fact, bagged and sold by terrarium supply companies, it is called 'ABG'. No surprise there.
But you can make your own for a lot less than they charge for a small bag.
The basic mix, as I believe I mentioned in your Monstera thread, is this:
One equal part each for epiphytes:
Perlite
Fir bark (Orchid bark)
Chopped coconut husk
horticultural charcoal ( many people omit this however)
ground coconut coir (sold in pet stores as Eco Earth)
optional for lithophytes (aroids that grow on stone)--Aliflor, LECA
For terrestrials (like your alocasia)
add to the above mix and equal part of your bagged potting mix
This is a porous fast draining mix that allows the roots of your plant to uptake only the water it needs and allows the rest to quickly drain away. This helps prevent overwatering, makes air pockets that allow roots to branch more freely, and generally makes plants extremely happy.
The only peat contained in this mix is what may be in your potting mix. Do NOT use sand, it compacts and can cause water logged soil.
I don't grow my plants in the house, but I use this mix anyway, because the plants thrive in it. It can rain on them everyday and they won;t be overwatered.
If you plan to keep a lot of aroids as houseplants, it would be in your best interest to invest in the components of this mixture and utilize it. Other tropical plants also like it.
Also make certain that your plants are in containers that have a LOT of drainage holes cut in the bottom. A plain black nursery container is the best thing to use. You can then set that container inside a decorative ceramic (which should ALSO have drainage holes) and use a saucer underneath.
WillC said:What you described as "cramped" roots is what I call appropriately or moderately potbound. You can save yourself a lot of problems if you resist the temptation to move your new plants into larger pots or by changing the soil.
Gina1960 said:Since you are already done the deed, I would wait until you need to repot again. But be careful NOT to overwater your Poly. They do not like wet feet
Gina1960 said:You probably will not find actual ABG at your local nursery. It is sold online mainly, by terrarium supply stores like Josh's Frogs and the like.
DaisyI said:Hmmm... I'm worried about the rocks on the bottom. The chances are the soil is not draining because of that layer of rocks. When unlike materials are layered in a container, it forms something called a perched water table. The bottoms of pots already form the first PWT but, adding a layer of rocks adds a second. Every layer the water goes through slows the flow so, the top layer (potting soil) is too wet too long. What I am describing could be death for an Epiphyte.
You will have to get Gina1960's advice on were to go from here. She is the Aroid expert, not any of the rest of us who have answered your questions.
Gina1960 said:Well, I repot at any time that I think I should. If my plant is IN a pot LOL many are not. I don't adhere to any rules about repotting being 'bad' for my plants, because frankly, nothing adverse has ever happened to a plant that I repotted. You just have to be careful of the root system. Don't wash the roots off. Don't try to remove all the old potting substrate. Just fill your new container 1/3 or so with the new mix, unapt your plant gently, let what is going to fall off fall off, maybe give it a gentle shake to help that happen, set it into the new pot and fill in with substrate.
Just make sure your container isn't too large for the root system.
You don;t have to buy already made ABG. All you need is a bag of perlite, a bag of orchid bark, a bag of horticultural charcoal (if you want to use it...I myself do) and some chopped coconut husk (which you can omit if you can;t find it but most pet stores have it, it comes in a 'brick' and you break it off and hydrate it. All the other stuff you can get at Home Depot or Lowes.
