My Bulbil Experiment

I've been growing garlic for many years now but have never actually grown it from bulbils before. So last Fall I decided to plant some Carpathian bulbils because I wanted to see what a round actually looked like.

The first thing that I noticed that I thought was a little strange was that almost all of the bulbils I planted scaped in June like a normal hardneck would. I didn't think they would. If I had to put a number to it, I'm going to say that around 95% of them scaped.

The second strange thing that I noticed was that every plant that grew a scape, grew a bulb. Not a round but a small bulb with individual cloves. The plants that didn't scape did produce a round. Here's what the small bulbs look like:
{{gwi:365334}}

The bulb in the picture is just under an inch and a half in diameter. They really aren't ready to be harvested yet as all their leaves are still dark green but I've been pulling them up to use early.

Anyway, just thought I'd share this info and I was also wondering if anyone else has experienced this before.

    hello Rodney, I've been growing my garlic from bulbils for a couple of years now and most years, harvest a combination of rounds and small bulbs depending on the variety.
    When I was searching for information about growing bulbils, found this blog http://goingtoseed.wordpress.com/2010/07/15/garlic-bulbil-harvest/
    and this article by Snakeroot farm http://www.snakeroot.net/farm/GrowingRoundsFromBulbils.shtml that explains about how planting dates can affect whether you harvest rounds or bulbils.
    I prefer rounds as they tend to produce much larger bulbs the following year. This page from Boundary garlic https://www.garlicfarm.ca/garlic-bulbils.htm is also really helpful and explains how large rocambole bulbils often produce small bulbs like the one you've harvested. I really enjoy growing bulbils as it allows me to eat more of the bulbs and not have to hold back as much for planting stock :)

    Very interesting links. Especially the one by Snakeroot Farm. I wouldn't have thought that different planting dates would have made such a difference between getting rounds and getting bulbs. I'm definitely going to have to continue to experiment with bulbils. Unfortunately I didn't let any of my hardnecks produce bulbils this year so my experiment will have to wait until next year.

    hello Rodney, checked your profile and I can't send you an email. I still have a good handful of assorted unnamed hardneck varieties of bulbils that you are more than welcome to. Just pm your address to me and I'll post them to you. Here's a picture of what they'll turn out like. I am pretty sure that there's a porcelain, a rocambole and possibly a purple stripe. Can't be sure because they were given to me by other gardeners and/or bought at farmers' markets for consumption :)

    zqnmegan, thanks for the offer but since you live in New Zealand I don't really think it would be feasible to send the bulbils all the way over here to the U.S. (there's the cost of sending them, then trying to get them through customs, etc.). If only you were in the U.S... lol

    Update. I didn't plant any bulbils this year so as I said previously, that part of the experiment will have to wait. However, there is a part two to this experiment. I planted both the rounds and the cloves from the small bulbs that were grown from bulbils. I'm curious to see which produces larger bulbs next year.

    Hello Rodney, I planted both bulbils and rounds/cloves from small cloves at my patch at the community garden this year and they will be ready to harvest from mid December through to the end of January, depending on the variety. There were quite a few left over that I couldn't bear to discard so put them into pots and polystyrene boxes at home as per this photo. I haven't figured out how to upload multiple photos so will post a photo of the bulbils in my garlic patch in a separate message.
    The goingtoseed blog has been updated with a timeline of the progression of planting bulbils to first year rounds/cloves to full sized bulbs.

    Well once again, thanks for the link and the photos, Megan. From the info that the Going to Seed blog gives, it can take three years to get large bulbs from bulbils. That's actually something I haven't read before. I had always read that it takes two years. Of course, one of those years includes the phase in which the garlic is a round. I wonder if by skipping the round (which most of my bulbils did) will I be able to shave off a year and have mature garlic more quickly.

    How closely do you plant your bulbils? They look like they are fairly close together. When I planted mine last fall, I planted them a couple inches (5 cm) apart. I'm thinking that spacing has something to do with my bulbils growing small bulbs as opposed to rounds as well as the timing of when I planted them. It seems that there are a never ending amount of different variables that need to be experimented with.

    As for posting multiple photos. If you use the upload button here on GardenWeb, then you can only post one photo per message. However if you first upload the photos to Photobucket you'll be able to post more than one. All you have to do is copy the HTML link from Photobucket and paste the link into the body of the message here.

    thanks for the advice on how to load multiple photo's, will have to sign up for photobucket first:)
    I tend to just sprinkle the small bulbils without any attempt to space them out accurately, although I'll give the pea sized bulbils a little more regular spacing.
    have not kept sufficiently accurate planting records to observe the size of the resulting bulbs grown from 1st year rounds but at a guess, 1- 1 1/2inches
    will record the sizes of this year's harvest and let you know.

    I've never raised garlic from bulbils, preferring to use the traditional clove method. But there is a soil-borne pest of garlic, Garlic Bloat Nematode, which is very destructive & is currently spreading. The nematodes spread with bulbs grown on infected soil, and will infest the soil at the new site. Even commercial stock should be considered as potentially infected, since there is currently no organized testing program for GBN (I suggest calling the company before ordering). The bulbils (unless they have soil contact) should be free of nematodes, and represent a safer way to share garlic stock. That is why the blog mentions growing a new garlic first in isolation for bulbils (and then growing the bulbils) rather than planting the cloves directly into the production field.

    For those concerned about the possible spread of GBN into their gardens, I will be offering bulbils as an alternative for any hardneck garlic that I share in the future, and recommend that other collectors consider doing the same. I'll also be throwing some bulbils for each variety in pots each year... these will be a backup, should the Fall planted cloves suffer a crop failure (as happened to my crop in 2012).

    My own bulbil experiment will be to remove only half of the scapes from each hardneck I grow, and allow the other half to develop bulbils (which will be harvested along with the garlic). Conventional wisdom says to cut off the scapes, to stimulate bigger bulb growth. When I last grew Rocambole garlic, I allowed several to form mature bulbils, and did not observe a reduction in bulb size for those plants. I intend to compare the bulbs of cut vs. non-cut for all my hardnecks, to see how the bulb size is affected. I'll look for this thread next Summer to post the results.

    Megan- You're welcome. Always happy to help.

    zeedman- Thanks for the warning about Garlic Bloat Nematode. Do you know if it's exclusive to garlic or does it affect other alliums like shallots?

    And that's something that I wasn't even considering was whether letting bulbils grow on the scape has an affect on harvested bulb size. It seemed like common knowledge that you cut the scapes to increase bulb size and I've always cut my scapes without question. But now I'm beginning to wonder how much of the advice about growing garlic is based on circumstantial/anecdotal evidence and/or hearsay and how much is based on fact.

    I'd very much appreciate it if both of you would give an update on your findings.

    As for myself, this will be a many years long experiment for me. I've decided that I'm only going to use German Red bulbils to conduct these experiments as German Red is a popular and easily accessable rocambole hardneck variety. Everything I've done up till now has been on a whim. From here on out, I will be keeping meticulous records about everything I do. When I plant, the spacings I plant, when they sprout, when they die back, the percentage of rounds vs. bulbs, the size of the first year bulbs/rounds from bulbils, the size of second year bulbs from rounds and cloves, soil amendments added, etc.

    I found this site that are selling garlic bulbils (by the head) I will order some to experiment. What time of year is best to plant them ?

    Another thing that I have learned here is if you harvest garlic early, you will get single cloves. I like that idea too. HOW early is that before garlic divides into cloves ?

    I assume the best time to plant bulbils is in the fall when you plant garlic cloves. But I would think planting in early spring should be fine. Although I can't say for certain as I only have one year experience with bulbils.

    If your garlic follows the same schedule as mine then it would probably be in late May or early June for when to harvest single clove bulbs. It's not something I've ever paid attention to but I know that my bulbs are already well divided in late June and they are usually ready for harvest in mid July.

    Unfortunately I didn't keep as good of records as I wanted to. Last Fall I planted both the mini-cloves (from the mini-bulbs) and the rounds that resulted from the Carpathian bulbils I planted in 2012. They were planted last Fall in two separate groups in the same soil with the same sun exposure. However, I forgot to label which ones were rounds and which were mini-cloves.

    I just harvested them and there was a big difference in size between the two groups. One group had bulbs only about an inch in diameter, give or take a quarter inch. The other group resulted in bulbs between 1.5 and 2 inches in diameter (I'm pretty sure that these were from the mini-cloves but am not 100% certain).

    I've got a lot of German Red bulbils that are growing right now so I will plant them this Fall and start this entire experiment over again.

    Rodney,

    I suggest that the larger bulbs came from the rounds, and the smaller from the smaller cloves, although that may seem to be counter-intuitive. Eventually the mini-cloves may size up, but from what little I have seen, the results from your larger rounds will size up sooner.

    When it comes to bulb size versus removing the scapes or not, I missed one scape on my Viet Namese Red this year. That one produced a bulb barely half the size of any of its neighbors whose scapes got removed. For that variety at any rate it makes a real difference.

  • zqnmegan
    9 years ago

    Hello Rodney, would be really good to see photos of both sets of bulbs when you have time to load them.
    I've noticed the same as OldDutch in that my larger rounds produce bigger bulbs than smaller/similar sized cloves when both have been grown out from bulbils.
    Possibly because most of my hardnecks have been grown out from bulbils, I still manage to get good sized bulbs with the scapes left on 2.5 - 3' on average - imagine the whoppers they'd become if I started cutting the scapes:)
    I've included a link to an article by Paul Pospisil where they've observed increased vigour in subsequent generations of garlic grown from bulbils.
    Here's a form that I found on the Seeds of Diversity site that might be useful if you want to start keep records of your garlic harvests http://www.seeds.ca/proj/gcgc/GCGC%20Garlic%20Observation%20Form%202005.pdf

    It's quite possible that I have them mixed up. If everything goes as planned I should find out for certain in another two years. haha

    It really irks me that I didn't label the groups. As you can see in the photo, the size difference between them is huge. That's astounding to me because I would have thought they'd be closer in size.

    {{gwi:365340}}

    The photo is not great but the six decent sized bulbs on the left were from one group, the six puny bulbs on the right were from the other.

    Thanks for the links, Megan.

    great harvest, be interesting to record the bulb size & weight of the biggest bulbs and compare with the subsequent harvest from them. The smaller bulbs are fiddly so I usually dehydrate them and make garlic powder from them - just crush them skins and all and spread onto baking paper then onto the drying tray. Mine are starting to peek through their mulch - shoots are up to about 3".

    I've been randomly sowing bulbils around my various gardens for some years. The result is that there are always some garlic plants, even if rather small.

    hello Rodney, thought you might be interested to read this update on the Snakeroot farm page - am trying it out for myself this year. They found that the yield of rounds was better when planting in clusters and a lot less work:)

    I am going to toss in something here.

    It seems to me that one can have clove planted garlic revert to rounds, if the growing conditions are either just wrong or planting dates too far into the summer.

    I am trying a mid summer planting of cloves from a new crop Mexican creole to see if that is dependable. To this point it more or less looks like it might be. I hope to be able to harvest the creole as rounds late enough to have it store until next spring. Fall planted creoles have not done well for me here in Minnesota. Maybe spring planted will do better, that is the second half of the test.

    I am doing a very similar thing by a midsummer planting of Copra onion seed in order hopefully to get sets for next summer. IMO onion sets are that species' version of rounds. I had some late planted Copra that didn't size up at all last summer, but when planted back as sets this spring did very well with no bolting at all, every bit as well as the commercial bunch of Copra plants I bought. In fact I cannot tell the difference in size now that they are harvested and mixed.

    Fun stuff, aint it! just trying to salvage a bit of knowledge from my past screwups, dontcha know!

    Do you grow the bulbils the same way as the cloves? Seed in fall, harvest in early summer. Then again seed in fall, etc....?

    For rounds, can you just keep the bulbs in ground over summer?

  • RedSun (Zone 6, NJ)

    Also, I'd like to get some bulbils if anyone has any extra to share. I'd like to add to my garlic collection. I'm still new to growing garlic....

  • zqnmegan

    Here are two clusters of rounds grown from entire umbels planted without removing the spathe. Am pleased with the size of the rounds; it was much easier to harvest and no mini bulbs. Planted 31 May and lifted 20 Dec 15.

  • zeedman Zone 5 Wisconsin
    8 years ago

    That is impressive. Much easier than separating & planting all of the bulbils... and the closely crowded spacing might better encourage the formation of rounds, vice small bulbs. I'll have to try that next year.


    I had very heavy bulbil production this year - including a lot of stem bulbils on most of my artichoke garlic. My previous efforts to get bulbils to survive in the ground over winter failed, so I am starting them indoors in pots. I particularly hope to get the stem bulbils to grow, in hopes that they might leave any bulb-borne diseases behind, and lead to larger bulbs in the future.

  • RedSun (Zone 6, NJ)

    Planting bulbils is kinda easy. This year, I sprinkled the small bulbils, just like spread seeds. For bigger bulbils, I still dug trenches.

    Last year, I planted about 600 German Red bulbils. About 500 of them are large rounds, about 3/4 to 1" large. I got about 80 of them small bulbs. I do not mind getting bulbs. I replanted them this year as regular garlic and I expect to get good sized bulbs this year.
