Leaves

2 different leaves same plant. I see this alot across all my plants at one time or another. Thoughts?
@DreamMachine #happyplants #pothospack
Probably a pest, not sure which one though
@planthoe40 hmm! I’ve never come across this before. My first thought was a pest like @Slyvie mentioned, but let’s ask @SuperbRaspfern to be sure?
Edema see how the spots are in lines following the veins. Her cells got too full and burst. In time they will scab over.

Pothos hate to be overwatered! Chunky soil, root rot treatment etc.

I use

1/3 peat moss
1/3 perlite
1/3 bark

1. Remove from your pot, to check the roots. If there is anything brown black or mushy you have rot and will need to cut it all off. Keep only the healthy roots they will be whitish in color

Now root rot comes from a bacteria that forms in your soil and then attacks your plant. So treatment is absolutely necessary.

2. Cut off all affected roots soak what is left in:

1 part peroxide + 3 parts water and leave in the peroxide mix to soak for 5 minutes this will kill off the remaining bacteria. It will bubble pot and fizz this is good it’s killing the bacteria.


3. Next is soil, the best
choice is to throw it away. It’s safest. Or bake it for 1 hour in a 200
Degree oven, not the greatest because it REALLY stinks. But it’s effective. Or the most risky way is to thoroughly flush your soil out with your peroxide mix twice! You need to be very careful and do it thoroughly because if even a teeny bit of bacteria is left your rot will come back.

4. Now the pot, it also has that pesky bacteria you must scrub it out with soapy water very well and then also scrub it down with the peroxide mix.

Now you can plant her again. Be sure to add some perlite to your soil for aeration. This will help oxygen reach those roots and I avoid bacteria growth in the future.

Sorry for the late response. I put in a long garden day! @DreamMachine Thanks for the tag Nadia.
@SuperbRaspfern ohhhh! Follows the veins 👍 👍 📝 📝 So, can edema happen anywhere on a leaf for any plant, or does it usually happen in certain areas for certain plants or types of plant?
Yep, edema happens anywhere even on the stems!

Usually on pothos these leaves will sort of hang down due to being waterlogged. They usually drop before they even get a chance to scar. @DreamMachine
@SuperbRaspfern just to clarify, on vining like pothos, can edema happen at any point along the vine as well? Or is it more likely to affect oldest or newest growth first?
So, plants have a xylem, it's their vascular system that carries water and nutrients from their roots up.

Oedema will affect the lower leaves first. This is often missed and people think it's old leaves dying off. But, it's the first sign of overwatering.

It's important to note, that overwatering is not the only cause. Too high of humidity affects transpiration and evaporation can't happen. Like us not being able to sweat in high humidity.

The leaves have what is called a boundry. It's a layer of air around the leaves that affect transpiration.

With too high of humidity or no air flow the boundary layer thickens, water accumulates outside the stomata, and transpiration drops.

This leads to a plant holding on to too much water. Upping the chance of oedema damage. With air flow the boundry layer thins allowing for transpiration. A critical process for healthy happy plants.

With no transpiration the water and nutrients can't pass through. Like our vascular system when someone gets clogged arteries. It's bad news. It's also bad news for plants. The water needs to move through or damage happens.

That's why I keep fans running continually in my plant rooms. It's necessary to keep healthy plants. Plants need help indoors to mimic what they have in nature to stay healthy for decades. Outdoor they have wind for plenty of airflow.

Hope this makes sense. Have a good day I'm off to can some of my veggies I spent hours picking yesterday!!! ðŸĐ· I'll check back in tonight if you have any more question or need further explanations.

Haven't shared my plant family for a while! ðŸĐ·
@DreamMachine That was a great question my friend!!!
