Help me diagnose Mircale Fruit problem

MerlinMerlinJune 2, 2014

Hi guys,
I planted a Synsepalum dulcificum (mircale fruit) from seed some years ago.
It's been doing ok even if every winter some leaves fall and the growth stop until summer.
Although this years, new leaves stay small and really pale while spot of rust/discoloration is appearing on old leaves.

Soil : 50% peat moss / 50% perlite
Water : I let tap water sit for 24H
Fertilizer : none

I'll be happy to provide any more information if needed.
Any help is really appreciated.

Why no fertilizer?
Would def green up those pale leaves and help the plant thrive.

iron or nitrogen would help

Would 20-20-20 be ok?

Most tap water is at the least neutral PH and oftentimes much higher. Start using rain water instead. They are acid lovers. Using Sequestrene 138 can help. This is an iron chelate.

I started using rain water a week or so before i made this post. After almost a month, I still see no sign of recovery. I just bought a PH tester+PH down bottle over internet so we'll see how it goes after adjusting PH to 5.

Hi Merlin - et-al
i got one a couple of months ago

it doesnt seem to be growing a bit.
how much sun do you give yours ?

I am trying to figure PH / water out now
cant always give it rain water, but, i can let my water sit out and add a drop or 2 of vinegar.
(raw apple cider vinegar)

I understand lemon juice is more stable
and is good for chelating calcium.

also, ascorbic acid (which i have) buffered vitamin C

any ideas which one is best ?

It looks like iron chlorosis or nitrogen deficiency.
They do need a fertilizer routine since they are going to use up whats in the pot and it needs replaced.
Good luck

Ok thanks mr. greendumb
but do you think those deficiency could be caused by wrong PH witch led to a bad assimilation of nutrients?
Also what fertiliser would you recommend?

acidic soil can reduce nitrogen uptake.
