A lot of citrus seeds have several embryo's in them, so its normal to get one, two, three, four or even five sprouts from one seed. One lady I know of found 7 sprouts from one seed!

Some people leave them as they are, but in my opinion it is best to separate them or one tree might take strength over the other. I removed all of mine - I had 2 seedlings from 3 grapefruit seeds, two mandarins and a lemon. They are all in individual pots and seem to be growing happily enough :) be careful when doing it though, make sure they are about 1cm tall, if not more, and loosen the soil around them gradually. They should come apart pretty easily, but being careful is important.

Are you growing anything else form seed? I love growing from seed lol, I have quite a few on the go, and am considering using the winter to stratify a couple of peach pits :)

Because of where I live and shipping regulations, I'm growing lots of things from seeds-- plants just aren't available. At the moment, I'm most excited about the citrus-- both local natives, and seeds from imported citrus fruit. The ones that are now up are seeds from my imported store-bought lemons and oranges. Also, I'm starting some blood orange seeds that a nice stranger mailed me (not up yet, but any day now). My strawberry papayas are coming up nicely, but I'm still waiting for a pomegranate, guava, macadamia, cashew, and a few others. (Other than my citrus, I'm using purchased seeds.)

I think I'll wait another week before splitting my orange seedlings. I want to make sure they survive because they are the only orange trees that came up from that batch of seed. So, will they be genetically identical?

It depends on the type of orange they were. The vast majority of citrus come true to type, only a few don't. I have read meyer lemons don't, and the word 'templar' orange seems to spring to mind. If you do a true to type citrus search on google it will give you a full list.

Growing things from seed is very satisfying, but citrus can take a while to fruit and flower so be patient. Key limes probably fruit before any others, in 2 to 3 years. Lemons and mandarins slightly more so. The good thing about you growing seeds is your climate (yes, I read your other post haha). Citrus should have the minimum juvenile period in such a climate, so will reach maturity and fruiting before they would in my climate here in England. Keep us updated on your seedlings progress, pics would be nice :) I like seed growing lol

I'm bumping this thread because this has now happened to me with Flying Dragon rootstock seeds. Problem is my twins are in a root riot cube, not dirt, so any ideas on how to separate would be great!

I may have to actually plant them in a one gallon container and let them grow together for a while?

Thanks
