Started Grapefruit from seeds
« on: December 19, 2017, 04:37:30 PM »
I visited Kurt(Nuba Bear) last week and ate some of his grapefruit so I took some seeds and got them started. I peeled the seedcoat off and put them on a damp paper towel in a ziplock bag. It took 9 days to germinate. I transplanted them into a community pot to grow today. 5 of 7 seeds sprouted and I'm waiting on the other 2 to see if they grow. I was surprised to learn that you can't let the seeds dry out so I soaked them over night since I had them in my pocket for the ride home. You can find videos on this method, it works on all citrus.

Ragun

I'm trying something similar.  I saved seed from some oranges that a neighbor harvested and gave me.  The orange trees have been growing for approx. 20 years, and the neighbor says they think the variety is Louisiana Sweets.  I wish I'd read your post earlier, though.  Instead of sprouting the seed in paper towels, I planted the seed in cups and put the cups on a heat mat.  I guess I'll wait and see what happens.

I'm glad you posted, I needed to water them. 4 of 5 popped up and one had 3 plants growing from it. I've researched and usually when you get 2 plants from 1 seed, the biggest plant will be more like the mother plant the seeds came from. I didn't see anything about 3 popping up so it's a wait and see thing.

Will these trees be for root stock to graft? Or will they produce the safe grapefruit that you are from Kurt's tree?

This thread is started at a perfect time for me to follow along. I planted 6 Clemintine seeds and 5 are up.

I will take pictures in the morning.

These will be to grow fruit. It might not be the same but it could be a good grapefruit when it decides to flower. That's how many fruit trees were developed. It's like a box of chocolates, you never know what you're gonna get.

I've read it could take 3-5 years and some places say 10 years. It's just an experiment to see what happens. When the tree gets big enough I can graph a good grapefruit branch to it.

The grape fruit that grew from my sisters tree did not produce trees that would bear fruit. They are healthy trees about 15 to 20 feet and have thorns that will let the air out of you if you back into one. My sister's tree produces bushels of very large tasty grapefruit. I think you need to graft onto the stock from the seed. I look forward to your comments.

Similar to Ragun, my citrus from seed experiment is motivated strictly by curiosity.  Assuming the seeds germinate, I just want to see what happens.  For fruit production purposes, I realize I'd be much better off starting with a grafted seedling.  In fact, I'm considering buying one of the newer Orange Frost satsuma seedlings to add to the garden.......

Daniel, there could be a few thing happening.

I'm not an expert on citrus but have been researching and this is what I found.

How old is the tree? It could take up to 14 years before it starts producing fruit. Citrus trees don't really go by years, they go by how many nodes/nodules/set of leaves it produces and that varies from tree to tree. If you prune the tree before it starts producing that lowers the node count and the tree has to grow those back to get to the magic number that makes them set fruit. Some trees will also produce dry fruit the first 2 years before they finally start making edible fruit. It's best to clip off the first fruit set to allow the tree to mature another year. I saw a few people say that the tree needs a frost to kick it into production, I'm not sure of that due to most citrus is grown in Fla. Maybe it just pertains to a tree grown from seed and most growers use a graphed plant, that makes more sense to me.

How many hours of sunshine does it get a day, they need at least 8 hours.

Soil conditions and fertilizer may also be a condition slowing the growth/production.

With the tree being 15-20" I would think it should start flowering soon. It's been there that long so have patience and let it grow.

Citrus seed update: The grapefruit are just slowly chugging along in the greenhouse even with freezing temps outside. The pot on the right has the seed with 3 plants growing from it but it's hard to see.

I also started some more seeds from grocery store fruit, 1 mandarin orange, a few large lemon and a small lemon seeds.

What kind of lemons were they?

I have a Meyers lemon I started 2 years ago.

Thanks for the update.

DUH, Yellow!!! LOL I don't know, they weren't labeled. How big is your lemon tree now?

It looks like you topped it, has it flowered yet?

Yes I topped it last spring. Took off half its growth roughly 10".
I wanted to keep it compact since it will have to be moved inside each winter.

This will be its third summer and it has not flowered yet.
As you can see here I have a small piece of Christmas Cactus growing in the pot. It was supposed to be temporary but it is VERY happy co-existing with the Lemon Tree.

Update on the seedlings, I left them under the trees all year and they're growing.

Here's the plant that had 3 seedlings sprout.



Big lemon seed from the store


These are the grapefruit, they're growing a thicker trunk than the lemons
