I need a little advice from people who have experience in growing lemon from seeds.
as you can see on the picture attached, my lemons are growing fine but the trunk is so thin that after a while it breaks and the whole thing falls down and dies.
Okay. It looks like you have some other seeds that have contaminated your soil. Those sprouts in the new picture with the long seed leaves are definitely not lemon.
The one in the front left, however, looks like one. The wilted one on the right with the pinkish stem definitely isn't.
They're very, very green when they sprout. If I get a chance, I'll post a picture of some calamondin seeds sprouting in my greenhouse - they're in the same family and will give you an idea what to look for.
I've seen a 3-4' grapefruit tree growing in a half-lit townhome and thriving. The low light means they probably won't fruit - but they shouldn't fall over and die like the ones you have there.
thank you very much ! I think I have found out what the problem was eheh
those skinny ones are in fact Goji berries which someonelse planted there whitout me knowing
I noticed the new one at the bottom left which is different so I guess that this is the lemon tree
Ah-HA! Dr. Watson, we have indeed solved this one!
I meant to post this earlier but was derailed by a batch of Senna Alata and Loquats that needed potting.
In the image are some sprouts a little older than yours. Generally, it seems that they'll take a good 10-20 days to come up, then grow at a decent clip. I have some two year old Key Lime trees I started from seed that are now 4' tall - and as it warms up I bet they'll easily grow another 2-3' this year.
If you have access to a tree, lemons also start well from small cuttings, provided you use rooting hormone, take off all but one leaf, then cover with a clear plastic bag to keep the moisture in. I've had a 60%+ strike rate that way.
Good luck. Wish /I/ had some goji berries growing on accident in one of my pots.
The "rocks" are actually a bit of perlite, a loose soil additive. Citrus don't like being soggy and appreciate the extra drainage. If you ever see the orchards in central FL, they're growing in almost pure sand and thriving.
I'm not sure on the lights. I've put mine in full subtropical sun and they've thrived - probably the closer and brighter the happier they'll be, provided they're not being cooked.
(Oh... and I have various little somebodies around my house that mix up my pots on a regular basis. Not that I'm much better. If I don't label things, I tend to get lost!)
