Kratom Leaf Photos

It’s actually not that difficult to determine whether or not you have happy Kratom plants or not; healthy leaves are broad, with a rich green color. So, whenever the leaves don’t look as lush as they do in the first image below, I will walk you through the most common problems and how to fix them.

Notice how silky it looks, how the edges are all smooth, and there’s a deep, green color to the leaf. Also, this leaf is large and broad…another sign of a happy Kratom plant.

The most common problem is UNDERWATERING your Kratom plants. What has worked best for me, is to wait until the top 1″ or so of the soil dries out before watering again. And then, when I DO water, I place the plants in the bathtub, and for each gallon pot size, I run 1/4 as much water through the soil. So, in a 1 gallon pot, I water it with 1 quart of water, letting it sit in the tub until the water has drained out of the bottom.


Notice how it wrinkled at the TIP first…this is important. If

the plant is curling and drying out along the edges and not the very tip instead, it’s most-likely a sign of OVER-watering. But this poor leaf wilted first, and then started to curl over several days, so you have plenty of time to react.

Next, when using hydroponics or plain soil, often the Kratom leaf, which needs a lot of nutrients, often doesn’t get enough. This is easy to tell because the Kratom leaf will turn pale, and start to take on a yellowish appearance.


Notice how it also has some browning around the edges. That is

further evidence that that leaf isn’t taking up enough water or nutrients. One of the EASIEST ways to fix this problem, is to make sure that you have the proper pH for the water you’re using.

Kratom plants like a pH of 5.5 to 6.5 best. And, most plants can’t absorb nutrients below 4.0 or above 7.0, so pH of your water is critical.

Nest is the opposite extreme; where the plants is getting TOO MANY nutrients. This can happen from over-anxious growers who want to give their plants LOTS of vitamins, but Kratom, when given too many nutrients, reacts quickly and negatively.


Overfed Kratom Leaf

Notice the large brown spots, commonly called “burn”. Also, notice how yellow and “rough” the leaf looks. Part of the white-ish look to the leaf is the nutrients actually perspiring out of the plant, and building up on the leaf itself. This is a VERY dangerous condition, and should be remedied the moment you’re sure of your diagnosis.



Not only does this one show heavy burning around the edges from

too heavy or rich of a nutrient solution (too much fertilizer), the leaf is showing signs of absorbing far too much nitrogen, which often tends to over-darken the leaf.

It’s an easy fix; though:

Simply wash your leaves, your soil, or your reservoir with fresh luke-warm water for about 5 minutes. Then, re-water or re-fill with fresh water, and if using nutrients, use half as much to see how the plant reacts.


If you have heavy damage from that looks similar to the immediate photo above, then before using half the nutrients, run WATER-ONLY for a week, wash your plant, growing medium, and reservoir again after the week is up, and THEN add 1/4 to 1/2 as many nutrients as you did when the leaf burn occurred.

Since Kratom is such a hearty plant, it gives you plenty of time to react to any number of unhappy moments it may experience as you get to know your plant and its growth cycle. Never push it too hard, and know that it’s a fast-growing plant, so over time and with a little patience, you will have more leaves than you know what to do with.
