Hi everyone,

I'm new here and hoping to get some advice on my alocasia lauterbachiana. Since buying it a couple months ago, it's grown several new leaves, but I've noticed many of the new leaves have slashes on them.

Is the damage likely to be a pest issue or am I doing something wrong?

Note: the plant is indoors next to an open sliding glass door, which allows it indirect and some direct sunlight during the day. I water thoroughly once or twice a week but the top of the soil does dry out at times.

What that looks like to me is mechanical damage done to the leaf while it is still all furled up before it emerges. It almost looks like maybe infant snails were down in the curled up leaves eating under cover. Inspect your plant really closely, in the pot, and on the outsides and undersides of the pot. I found a slug merrily eating the leaves off of my Monstera dubia a couple weeks ago

Do snails come out at a certain time like slugs?

I meant like at night, during the day, etc. I've read slugs come out at night, but I was curious about snails.

I find those little round snails on stuff at all times of the day. Also we have a snail here in Florida, it looks like a small apple snail, I don't know the species, tan with a sort of oblong shell....they are out at all times of the day.

Okay, just curious. That means if I ever get snails in my plants I don't need to get up at 1 am to go looking. Hilarious!

I've found a couple big slugs in the GH this season. Usually they don;t get in. Like I said one munched my variegated Monstera dubia. I found another on a Philodendron gloriosum. Just munching. I also have some damage on a couple Taccas that I know is from slugs. The ones I actually caught in the act are no more LOL

Hilarious! I have one slugging around my houseplants and cacti that I brought in for the winter. I haven't found it yet, but I keep finding its slime trails. Blinking

@Gina1960 thank you, I've checked and there aren't any snails but I did see what appears to be fungus gnats buzzing about 😩. Will have to deal with this as well. Any other possible causes for the leaf damage?

Fungus gnats mean your soil is too wet. That would not cause that damage. Something injured your leaves before they emerged. Something that could sneak down into the folds inside the cataphyll.

Not to change the subject, but what alocasia is that? I've seen it at Lowes and it's new to me. *Blush*

Another new leaf is emerging and same problem. I will have to keep an eye on it to try to figure out what critter is nibbling on it. I'm relieved it's not a disease infecting the plant. Will have to refrain from watering as much too.

It's alocasia lauterbachiana.

It can be finicky. I have a few planted in the GH. It always tends to look like its going to try to go dormant in winter. Mine always loses leaves and growth slows way down in winter.

Okay, it's a good thing I didn't spend $12 for one then!

Too much for me. Hilarious! I buy anything more than $6 and it usually dies. Glare
