Hi Maggs,
would you please provide a couple pictures of your
seedlings and a close-up on one of the leaves.

What temperature was the water?

Were the seedlings fully exposed to the sun?

How long was germination?

Please details substratum used?

Could we also have a look at the roots?

But..Hey!..you managed to grow Lemon seedlings..

Hi Jordan, thanks for your interest n my case...

This is so frustrating, I don't know how to insert pics in here but I
have taken a lot of pictures of the lemon. Can u tell me how to put the
pics in here?

Let's see, in the meantime I’m gonna answer some other questions.

1. The water was taken directly from the faucet so its temperature was +
or less 20ºC (68ºF)

2. The germination has took place in the inside of the house in moisten
kitchen paper and it took 10 days long. After that all of them
germinates and went to the roof top of the house (we call it “azotea”)
and the y had direct sun light. Nevertheless, we are in winter time so
we have no sun light at all and its cold in here. I live close to the
beach. Total time of the seedlings is 5 or 6 weeks.

3. The substratum I’ve use is “Tierra de Almácigo” or soil seedbed that
contains N+K+P+Mg, fungicides to prevent mold from our high humidity and
a perfect combination or porous texture. It’s the best of the best of
the substratum available for rookies like me.

4. Yes, I’ve take a look at the roots of the two dead lemons (now I have
two dead). The roots look perfectly normal and healty, but the stem
looks dryer than a martini and it has lost all their leaves.


Germinate lemons is really easy, nut you need to take healthy lemons
from the farm. Modern agriculture takes immature lemons from the trees
and its seed are unviables. You need lemons take from the tree when they
are fully mature

Then you consume thie lemon as always but preserve the seeds. You put it
in any Tupperware with moisted kitchen paper (like in the school) and
leave it in a warm place like your kitchen. Open the Tupperware from
time to time and change the paper if you notice fungus (like a black
stein in the paper).

10 or 14 days after lemon seeds opens and you can see the little root
growing. Wait a few days and then put it in the best substratum you can
find and… That’s all!

I want to use this lemons (very common and easy to germinate) as
rootstock for grafting Tangelo (Citrus x Tangelo) and Pomelo Rosado
(Citrus x Paradisi) in them.

Once I can manage to put pics I’ll do.

Thanks!

Hi,
it's a nice project you are working on...I wish I could help you
diagnose this issue. I dont want to create any expectations here so I
am going to be really honest and admit that this is going to be a
longshot for me. I do have a technical degree in
agriculture...however, I live in Canada and therefore I do not really
have a lot of experience with growing exotics.

A couple of things come to my mind:

1-salinity an alcalinity of the soil
2-cold weather and low sunlight
3-hardening period before transfer to "azotea”

As read on --

"You can often get yellowing of the leaves with lemons due to
chlorosis but this can be dealt with by feeding with an acidic plant
food."

Also on the same ressource--

"Although relatively hardy, keep your young lemon plant inside for its
first winter. For subsequent winters it can be left or protected
depending on the weather in you area."
