Hi Folks - I have a PPP and just when I thought it was doing well (like shooting out an almost fully pink leaf), some of the leaves have started turning yellow and dropping. The whole leaf turns yellow (except for the pink part) and then it falls off.

Also, that fully pink leaf is starting to wither and looks drier and worse for wear. The other leaves don't look thirsty or dry.

Anyone know what's happening with the yellowing leaves and the wilting pink one? Thanks.

Ps - since it's in the picture, the Alocacia black velvet is also yellowing in some spots. Bonus point for solving that mystery. 🙃

How often do you water these plants? Are they indoors?

When your Pink Princess shoots out a fully pink leaf, that is the OPPOSITE of 'doing well'. The all pink leaf has no cells that will photosynthesize, it cannot contribute to the growth of the plant, and will quickly yellow and die, like yours did. One all pink leaf is not a cause for immediate concern, but, if you start getting CONSECUTIVE all pink leaves, you will have to cut the stem of your plant below where the FIRST all pink came out to stop this pattern. Because if your plant only makes all pink leaves, it will slowly die.

Alocasla Black Velvet is a Jewel ALocasia. They like very high humidity, like this, and do not like to be overwatered.

About once every 1.5 to 2 weeks

Thanks Gina. I understand the pink leaf doing poorly, but why are the dark leaves also yellowing and falling off?

You mean on your jewel alocaisa? Lack of enough humidity #1 I can't see how it is potted up but there may be other factors. If you can separate the 2 plants and take a photo just of the top of the alocasia with the soil visible that would help

Hi Gina - here are some pics of the alocacia in her pot. You can see the leaves are yellowing. Confused

Btw, what's the difference between a black velvet vs a Jewel?

Also, what are the little growths coming out from the stem? (They look like long buds)

'Jewel' refers to a group of Alocasia. Black Velvet (a cultivar of Alocasia reginula) is in this group, as are alocasia sinuatis, alocasia reverse, alocasia melo, SIlver dragon, cuprea and others.

Did you pot this yourself?

The reason I ask is, your pot size looks too big for your plant. This is my Reginula for comparison. It is probably 3-4x the size of yours, and it is in a very small 2.5-3 inch plastic pot

This ALocasia Maharani (a hybrid jewel) is in a 2" pot

And this Alocasia reversa is in a 2" pot

All of these plants live in a greenhouse where the humidity ranges from 75-100% day in and day out. They are scantily watered because jewel orchids do not like to be kept moist. They like to dry out in between waterings. Overwatering is the #1 cause of death for these plants. Compared to other types of thin leaved ALocasia species, these are more succulent in nature.

The jewel orchid species come mainly from the rainforest floor in places like Borneo. Even though it is the rainforest, only about 2-5% of the rain actually makes it to the forest floor, so they are adapted with the thicker almost succulent type leaves to utilize as much water as they get and the extremely high humidity in the jungle.

The thin leaves species of Alocasia mainly come from Asia.

Yes I potted it myself. Based on the size of the leaves, I was actually thinking of putting it in a larger pot haha.

Thanks Gina for the info. I'll keep it dryer and mist it more.

How did you receive it? was it sent to you bare root, already potted...? I am asking because this is a tissue culture plant. Because of the increased and renewed demand for many aroids, some that have not been in production for years are now being mass produced again. Tissue culture plants go to the vendor in trays and are called plugs. A plug is general less than an inch on each side. The vendor is supposed to pot up and grow these plugs out to a marketable size, making sure that they establish good root systems and are capable of surviving with the shipping process and reacclimation to a new place.

But some vendors are sending out poorly established (or unestablished) plug plants and they may not do well or may take a whole lot more babying and care to get up to speed.

I got it in a 2" square pot. It only had 2 small leaves. I've had it for about a year now.

Jewel ALocasia really prefer to be underpotted

Plantani, in the photos of your Blushing Philodendron (Philodendron erubescens 'Pink Princess') and Elephant's Ear (Alocasia reginula 'Black Velvet'), the soil appears extremely dry. How often do you water and how much water do you give them? The potting media looks nice and chunky and airy which is perfect for Aroid health but I wonder if perhaps you aren't watering thoroughly enough or often enough.

Hi there - I've deliberately not been watering it because I was afraid I was over-watering it!! Arghh! Being a plant-care-giver is so hard! 🙃 I've been trying to water less and give more mist, but the 2 lowest leaves on the alocacia have completely yellowed since this pic was taken. 😩
