Paul: My Euryales have suffered from high pH tap water
(pH 8.7) in a temporary pond and then water nutrification that
took the pH up to 9.6, causing melting and burning of the leaves.
Kit: It probably wasn't pH that caused the melting and burning.
Did you use peat in the bottom of the pots? Too much fertilizer,
especially phosphorous, is the usual cause of melting. That's
what the peat and ingredients in the cocktail seem to counteract.
Paul: They are now recovering but the nursery suggested I
try your Cocktail for future nutrifying for a while. However
the nurseryman couldn't recall how he constructed the Cocktail
(concentrate or diluted) as his batch is several years old.
Kit: The single-most important ingredient is the humic acid
in Roots. I'm not sure how important the extra iron is to Euryale.
(It's Victoria cruziana that REALLY needs it and other Victorias
benefit.) You could try any biostimulant available with or in
combination with humic acid and peat.
Paul: I forgot to mention that as the nursery suggested, I
put 2 cups of peat moss mixed into the 8 litres (2 US gallons)
of pH 7 sandy loam garden soil around the Euryale, which arrived
in the mail with about 5 leaves each, (including one adult leaf
each). The peat wasn't all at the bottom where the fertilizer
was sitting on top of newspaper. The fertilizer recommended for
use was 1 cup (300 ml) of 4-3-2 pellets (containing blood and
bone, seaweed, composted animal manure with 5% humates).
Kit: Yikes! Repot instantly!!!!!!!!!!!!!!! Get rid of the
fertilizer! Go with sandy loam and peat, mixed is OK though the
bottom of the pot for the peat is better. Use smaller pots for
now with holes in them for sure. Maybe give a teaspoon of the
pellet fertilizer weekly until they recover.
Paul: The two Euryales may yet recover from their toxic
shock. While the two floating leaves on each plant remain crimson
red (a condition I suspect to be due to either the nutrient shock/high
pH/lack of nutrient availability during leaf gestation), after
I took your advice and put a teaspoon of the 4-3-2 pellets in
each pot, the red leaves appear to be EVER SO SLOWLY greening.
Kit: Red is not good but the greening is encouraging!
Paul: One Euryale has two new leaves gestating. The
slower of the two plants has one new leaf gestating, and the
older of its two red floating leaves is starting to rot. In an
attempt to fortify both plants against cell weakness and further
leaf decay I put a few cc's of the biostimulant SEASOL into the
soil yesterday. It's like ROOTS except doesn't have the humic
acid. Seasol is made from Tasmanian Bull Kelp.
Kit: Kelp is good and will help. Still I hope you can find
humic acid. Both seem to provide protection from fertilizer burn
while allowing needed nutrients to get to the plants.
Paul: I have bought another liquid product by the Seasol people
which has 12-1.5-7 for NPK. It has also 3.8% humic acid, but
I wasn't really sure about using it due to the high N. The Seasol
+ Seasol Powerfeed combo is also recommended by the Seasol people
as great in foliar application. I began a test on one leaf each
plant this morning.
Kit: High N, low P is good! You could use that in place of
your pellets. The combination with Seasol might do it for you.
But don't apply it to the foliage -- they don't like it at all!
