Welcome! Emilio,
Did you had a hail storm with small ice stones not long ago?
I ask because I see a similar damage to some of my plants, especially the ones with succulent leaves, after that happened..

Welcome! @Emilios. Please take a moment and go to your "Profile" and update your public profile, stating your location. City and state gives us the most information but just your USDA zone is better than nothing.

I grow a lot of Aloe and have for over four decades. They basically grow like weeds for me. I see all kinds of spots on my plants but am unsure what those tiny spots represent on your plant's leaves. Does your plant(s) have new, healthy-looking growth. Not knowing your location, I don't know where in the growth cycle your plants are. Could you post a couple of photos of the entire plant? Also, telling us how you grow your Aloe will perhaps help with a diagnosis.

On plants with thick leaves like aloe, sometimes mite damage looks like that. I get it on my orchids sometimes.

A spray with soapy water will usually nix all the mites. A couple of cc's of dish soap to a liter of water. Spray all surfaces of the plant and the soil surface. Rinse it off before you put it out in the sun. Repeat the treatment in 5 days to a week, to get the next generation - the soap will kill live mites but not eggs.

The spots will not go away but as long as they aren't increasing you know you got rid of the mites. New foliage should come out clean. If you can spray the plant lightly with water a couple of times a week, that will often keep mites away. They hate wet weather.

Hello bonitin,no there was no storm lately.But there is a lot of humidity late at night until early in the morning until the sun rise.
Hello drdawg,i dont know if i have updated my location correct.I live in Cyprus,i think this does not help you much about the conditions the plants grow.So i will try to give you as more informations i can.Yes,the plants have new healthy growth.The new leaves are green and have NO black spots on them.Most spots appeared i think in March.We have hot summers here (about 35-40 degrees Celsius,calm winters) and i water them every 5-7 days when the soil get completly dry,about 2-3 liters of water.The plants grow outdoors.Could this spots appear because of high humidity early in the morning and when the sun rise the plant gets burned???I will attach a photo that i belive a black line is caused from a water drop but i am not sure.I would like your opinion.If you need better photos from the entire plant(s) please let me know.
Thank you for your answers!!! Thank You!

I have never seen a line like that, Emilio, but I also have never seen aloe vera plants like the ones you show. I don't have a clue what's going on.

@drdawg yes its a very strange line Sticking tongue out I would like to ask you about watering.What amounts of water do you suggest for temperatures around 40 degrees Celsius and how often??

No, mites wouldn't make the big dark line on the leaf like that. The small dots, yes. I have no idea how that line would come to be there, unless it was some sort of mechanical damage?

In any case, it looks like you still have plenty of healthy foliage there. Keep an eye on the plants, to watch for any further damage but so far it doesn't seem to be hurting the plants, except for aesthetically.

Emilio, I have a feeling that Cyprus is perhaps more like S. California's climate than mine. I am guessing that you don't have much in the way of freezing temperature or frost, and when you do, it is brief. Being in the eastern corner of the Mediterranean, you might be even drier during the summer months than western Turkey and the islands off Turkey. I have cruised in that area during the summer, and remember it being hot and really dry. We are hot here in Mississippi, USA, but very humid and with thunderstorms moving through, giving us pretty ample amounts of rain most of the summer months. Our average high temperature from June through September, is in the 90's but our relative humidity stays above 75%. It is like a steam bath here in Mississippi.

Perhaps, because my climate is so different, someone in S. California, perhaps away from the coast and toward the desert areas, will chime in and give you some help. All my aloe vera are potted and I water those plants at least weekly. The potting media I use is so well-draining, I probably can't over-water my plants.

Again, my aloe vera don't look a thing like the ones you show.

Am I the only one who's aloe vera looks far different and grows far more prone than that shown by Emilio?

Emilios' plants look like the Aloe vera I am familiar with. Be aware that there is another aloe sometimes called Aloe vera chinensis which is now considered a form of Aloe officinalis (which usually has orange or coral flowers instead of yellow ones). Both Arabian aloes have medicinal properties but they are distinct botanical forms (and neither is Chinese in origin, despite what the name might suggest). Perhaps this explains the difference, Ken?

I cannot explain the spots and stripes on those aloes. New healthy leaves are a good sign that the plant will simply outgrow them. I wouldn't worry about it. Aloe vera (the true form, with yellow flowers and unspotted adults) is a very tough plant and actually pretty hard to kill in good light.

Our climate is similar (winter rainfall, summer drought, regular fog and humidity) but significantly milder in temperature (we get up to maybe 30-32°C). Aloe vera will usually turn grayish brown during the summer and shrink up significantly in response to drought, then recover quite fast when it rains again. Those changes are really only cosmetic and not something to worry about. I water the plants here every couple of weeks but that's probably more than they need in our climate.

I've never seen spider mites here. I am told they do not tolerate our high humidity. On the other hand, aloe mites (which we unfortunately do have around here) cause a totally different kind of disease which is manifested by disordered growth, wart-like tissue, and distorted flowers. They are not the cause of the spots you are seeing on your plants.

@dyzzyppyxy no,i have not damaged mechanically the plant.Its the same black spots in a straight line and made the photo from a bigger distance.Yes,there is a lot of healthy foliage and it looks like its just aesthetical issue for now but this plants are something new for me and i dont want to get in bigger trouble.For sure its better to see your plants grow as healthy as possible.
@drdawg as i know there are a lot of aloe vera species so it doesent surprise me that your aloe vera look different.Just google "aloe vera species" and you will get even more confused Sticking tongue out About the climate you are correct.No frost,snow or very low temperatures during winter at my location.Dry,hot summers with a lot of humidity during night until sun rise.Thats the only explanation i have about the straight line for now.That could be a water drop from the humidity (if humidity affects somehow this plants).

For the record, there is only one Aloe vera species. Many of the plants on the market (and the internet) which are labeled "Aloe vera" are not Aloe vera at all. To give you an idea of the big picture, there are maybe 500 total aloe species, of which A. vera is one (and my avatar, for example, is another). Many people assume that their random aloe is Aloe vera without considering the hundreds of other options.

I have actually had to stop people harvesting leaves in the public garden here because there are maybe 30 different aloes in there and only two or three of them would be considered medicinal. There are actually poisonous aloes out there (not many, and very uncommon) so it's good to figure out some kind of ID before cutting leaves from a random aloe.

OK, what plant is this? I have grown these plants for 40 years, have shipped numerous leaves for pharmaceutical compounding as well as shipping whole plants to those who wanted to use the leaves to treat skin problems. I have always thought this was Aloe vera.
