White Spots On Parsley Leaves

by Corne Froneman
(Almaty, Kazakshtan, Central Asia )


Question:


I have grown the Parsley from seeds. I bought the soil, but as I live in Central Asia, there is never a guarantee about the quality of the product that you get here...and everything is in Russian, so I don't even know what type of soil it is. The plant is indoors and receives lots of sunlight.

It has tiny white specks on the upper side of the leave, but nothing underneath. So could someone please help me identify this and what would be the treatment?


Answer:

Corne,

So glad someone from so far away from where I live in the United States views our website.

Let's start off by eliminating a couple of things.

First, I don't think your problem has anything to do with the soil you are using. In my opinion, if it did, your Parsley wouldn't be growing so well. Your photo (thanks for submitting, by the way), shows a well-growing herb.

Also, the amount of sunlight it receives shouldn't be causing white spots on the leaves.

The two things that could cause white spots, are insects or a fungus. If it's a fungus, you'll need to treat the plant with a fungicide made for edibles. If that's what it is, it should disappear in a few days to a week if you follow the instructions on the label.

Secondly, it might be insects. Aphids or spider mites can make white spots on leaves. Look for whitish webbing as a sign of spider mites. But, also caterpillars can do this as well. Do the white spots turn into holes? If they do, than it's definitely insects (most likely the caterpillar). Literally, turn over leaves and look for caterpillars. An insecticidal soap would be your best bet for this problem. Use the soap, and the insects should be a thing of the past.

Just don't ignore the situation. They are a common thing for Parsley, but if it is a fungus or an insect, either way, you have to get rid of them or the plant will become unusable.

Hope this helps and please let us know how it turns out!!

I have had this problem before in the past..
by: Jaye

Sweetie, do not pay any attention to this Brad or whoever he is! You are having white spots on your parsley because it is a soil problem! It is not bugs or caterpillars, some of these so called professionals are idiots! It is simply a deficiency in your soil or a moisture problem. Not enough moisture... I fixed my problem by taking my plant out of the pot and keeping all the roots in tact that I could possibly... Then I tried to get all the soil from the roots that I could get and I re-planted my parsley plant in a new pot with new soil and in 2 to 4 weeks it was thriving again, with no more spots. Change your soil my friend, it will repair your problem! Use some slow release fertilizer in the future.

Fixing the white spot problem..
by: Jaye

I forgot to add one very important thing.. Remove all of the affected leaves and stems but I would wait til I see some new growth before I removed all leaves and stems but as long as there are one or two not affected, I would remove the others and put the plant in new soil with slow release fertilizer and be sure your container is big enough because many people try to plant these herbs in small containers. I use one gallon or 3/4 gallon containers for my parsley. Those pint and quart containers will not make it for the duration of six months, you might see white spots on your leaves, if you try these small containers! :) Parsley plants like moist, well drained soil, so in the future try to keep your soil moist with a good PH near 6. You will not have this problem again.

White spots on parsley leaves
by: Anonymous

Sometimes white spots occur because of ambient air temperature is to cold thus soil temperature is not conducive for roots to take up nutrients. Parsley like basil has inherent difficulty taking up iron.

White spots on parsley
by: Denise

I also have white spots on my potted parsley. I didn't realize I had spider mites on a plant next to the parsley. I sprayed it with soapy water and I don't see any mites. The plant looks healthy but the spots are coming out on the new leaves.
I believe it is a deficiency in the soil. I am going to add fertilizer. Thanks for the tips.

Parsley White Spots that dust off
by: Anonymous

I have white "dandruff" on the parsley growing in a pot in my house. The white spots are on ALL of the leaves and are constantly shedding. This normal?
