An Exciting Update!

Yesterday morning, Saturday, April 25th, I woke up to a lemon sprout poking its head out of the dirt! Success! We have a Meyer Lemon plant!

This is the Meyer Lemon seed that was chitted and scarified, and then planted in a pot once it had sprouted. I planted it two weeks ago, and was about to give up hope that it would ever come up. Altogether, it took 39 days to go from seed to the first cotyledons.

Additionally, last week, a second chitted Meyer Lemon sprouted, so I planted that one as well.

The blood orange seeds, on the other hand, have all rotted. I dug up the seeds that I had direct sown, and they were rotten too. Oh well. You win some you lose some. I’m just so pleased that the Meyer lemon seeds are working.

Update on the Citrus Seeds!

It’s been 26 days since I planted/chitted the citrus seeds, and the update is….well…mixed.

None of the seeds that were planted directly in soil have sprouted yet.

One of my chitted blood orange seeds rotted.

The seed at the bottom of this image is just soft white mush inside a seed coating

But….. one of the chitted Meyer Lemons has sprouted! Hooray!

A sprout!

The photo above is from 3 days ago. Nine days prior to that, I had removed the outer shells on the Meyer Lemons, after seeing no changes to the seeds for 14 days.

This, according to Plant Parenting, is called scarification.

While most annual vegetable seeds do not require pre-soaking or any special preparation for germination, seeds of some natives, perennials, and fruits with hard coats will require a bit of extra work on your part, whether it be a longer chitting/soaking period, scarification, stratification, or inoculation with rhizobium bacteria…. Seed scarification involves scraping away part of the hard coating to expose the seed to water and gases that trigger germination. In the natural environment, temperature, soil microbes, and even fire can break down seed coats. Animals eat seeds, which are then exposed to stomach acid which breaks down the seed coat.

She has some very interesting suggestions for how to scarify seeds.

I just pulled off the seed coating using my finger nails. It’s hard to know if the scarification helped, or if the seeds just needed more time…

Now that I have a sprouted seed, I need to plant it! But how soon do I plant it? Should I plant it right away, as soon as I see a sprout? Or do I wait for the sprout to get bigger?

I couldn’t find any consistent solid guidance on this, so I decided to wait for the sprout to get a little bigger. Here it is two days after I first noticed the sprout (yesterday):

It grew a tiny bit more.

I decided to plant it at that point. I put it in the same pot as the direct-sown Meyer lemon seeds. As you can see there is no growth of the other Meyer Lemons (at least from what I can see above the soil). After planting the seed, I covered the pot again with a plastic bag to keep the humidity in, and crossed my fingers.
