Help...Yellow mint leaves with brown tips and brown spots

Post by Phyllis and Jim Hurle » Thu, 21 Jun 2001 20:38:58



We would love any helpful ideas y'all might have.

In an earlier post I mentioned that our new mint leaves on mint recently put
in the veggie filters were coming up yellow instead of green.  Now we have
some brown tips and brown spots showing on the leaves.  Also, the older
leaves are more yellow than before.  I have checked salt and nitrites and
nitrate and gh and kh and ph...all in fine limits.  Other plants are
thriving.  Even mint moved earlier is doing well (although I think I detect
some slight yellowing at the center of some of the leaves on the mint plants
put in water earlier.)  Before the brown spots began to appear, Rod
suggested I try some epsom salts to see about sulphur.  I have not done so,
yet.  Could this be a result of limited root systems?  Any ideas well
received!

TIA

J&P

Just out of curiosity:
Is this a new pond by chance?
What size is the pond, and what size is your fish load?

The reason I am heading in this direction is that my plants
such as mint did not do really good until my pond cycled.
This was about 8 weeks after putting my fish in.

This year I am having to pull and throw massive amounts
of very healthy mint as its wanting to take over.

The pond is two years old.  5400 gallons, light fish load.

I would add more fish! Always a good thing to do, and they will
help provide the nutrients your plants need.

Brown tips (on houseplants) generally means either salt built up in the soil
or too high of pH in the water.   Just trying to brainstorm ... what are the
readings on your KH and salt ?   But you say the Water Hys are doing great.
You have 3 kiddie pools, are they all interconnected & how?  Is the kiddie
pool for the mint in a more sunny spot then the Water Hys making the water
slightly warmer?  Not sure if you read my post, but my mint loves to be held
vertically between sheets of egg crates.  You are planting bareroot, but
how?

(btw, aquatic mint overwintered well, water temp 39-46F for months during
the winter).

Hope this helps,

Good thoughts.  The salt is 0 and the Kh good.

The kiddie pools have 2" PVC between them, sealed with paste epoxy as the
tubes exit.  It enters pool one from a barrel, flows out to #2 and on to #3.
Then it goes out to a falls and a stream return to the pond.

They are side by side. Same water in and out.

Looking at the mint today, I noted that ther may be a slight darkening along
the veins.  I wonder if better root systems will brong better color?  The
mint that has been in the barrel filers has a solid green.

I wish we knew what was going on.  We'll post any changes.
