Frequently Asked Questions

Here at Keene Garlic, we take pride in ensuring that all of our customers grow a successful garlic crop. If you’re new to growing garlic, it’s normal to have a lot of questions regarding garlic care. Here are some of the most frequently asked questions that we’ve gotten from our customers over the years. If your question isn’t answered here or on our website, we encourage you to send us an email or give us a call. We want our customers to be successful garlic growers!

Why are my garlic leaves yellowing?

Yellowing leaves on garlic plants

Yellow leaves can be normal or a sign that something is wrong

  • Is the soil too saturated with water?  We want the soil moist but not saturated.
  • Have you fertilized the garlic?  Garlic is a heavy feeder and yellow signs can be an indication of nutrient deficiency.  We do have a garlic fertilizer if you don’t have a multipurpose fertilizer in your mix.  
  • If your garlic was a few inches tall and was hit by some very cold temperatures which might cause tissue damage on the leaves, and you may see the yellow leaves for the rest of the season. Rest assured they still turn into beautiful garlic even with yellow leaves.  
  • Do you have any insect issues in your region? On the east coast, there are certain regions that are dealing with Allium Leaf Miner. Leafhoppers can spread Aster Yellow. So there are a number of pests that can and may affect garlic, so google them and be aware of what is in your area.
  • If the plant is prematurely dying, then there is a problem, and you would want to pull up the plant to see what is going on underground.  Remember, it may not look so pretty as the clove turns to mush as the sprout continues to grow and the bulb does not form until the last 3 weeks before harvest.  If you see the bulb rotting then, there may be a problem. 

Remember, you are gardening and there are multiple reasons why plants don’t grow and thrive which could be from weather related issues (which is very common this year), to insect issues, animals, and all the other things that go wrong when gardening.  It could be the seed too but remember that what you are planting as your seed stock is also our seed stock.  Our garlic is our is our livelihood. We are only planting and selling the best garlic that us small family farmers grow on a small level to provide ourselves and you with the best seed stock.  If we see an issue, then we know there is a problem with the seed.  If we don’t see an issue with our seed stock which is rare for us to find unless it is weather related, then we know if a customer has and issue with their garlic it is likely due to the environment it is grown in and can be subject to a variety of reasons why it does not grow.  We grow on multiple fields, test garlic annually, used the same seed stock for decades, keep our fields clean, use best organic farming practices, so our customers can have good seed stock too.  

A gardener many need to look back at their gardening notes, weather conditions and all the other reasons for the issue to get the bottom of it.  So please read through our website, as we have taken extensive time and effort the past two decades to provide as much information for our gardeners to be successful at growing garlic.  We know that by providing the best seed stock grown organically by small farmers on a small scale get customers superb garlic seed stock and the advice we give has led to successful garlic farmers and gardeners.  We know it works as we have so many successful garlic growers and customers that come back every year.   


Why are my garlic bulbs so small?

There are so many reasons why that could be.  First, when you have bulbs with multiple sized cloves, the small clove size in these bulbs will always grow into small bulbs which are usually around 1.5-1.75″, but the other size cloves usually size up to large and jumbo-sized bulbs.  Look at the pictures of the bulbs cut in half to see the sizes of the cloves. There are also many reasons for bulb size which includes from the size of the bulb and clove planted, amount of sun, climate of the season, soil temps (once soil temps hit 90 degrees the plant wants to die back, and it may not have gotten to its full potential in size), fertilization and nutrient levels in the soil, weeding, watering, and picking the garlic scape right as it starts to curl.  Much of this we can control, but we can’t control the climate of the season.  
Timing of the harvest is also critical. Harvest to early and the bulbs will be small. Harvest late and you can risk rotting bulbs or bulb wrapper breaking open. See our page on harvesting garlic for tips. I’m not sure what factors played into the small bulb size, but once those are corrected for what you have control over,  you really should have great bulb size.  

What Happened to My Garlic?

Garlic Garden Full of Weeds in the Spring

One of our customers planted garlic in the fall and covered the garlic with mulch purchased from a big box store. This spring, his weeds came up bigger than his garlic! Sometimes mulch or straw from big box stores can be full of weed seeds, so make sure you’re watching where you get it from and make sure the mulch is clean. If you start to see weeds coming up, make sure you’re picking them early so you don’t end up with this. I

t’s important to keep your garlic weeded so that your plants don’t have to compete with the weeds. This will help ensure that your garlic bulbs grow nice and big. Thankfully, he resolved the issue, and his garlic plants have a good chance for survival and producing a garlic bulb.

What is the best way to apply fertilizer in the Spring?

Organic Garlic Fertilizer

In the spring, broadcast the fertilizer over the straw using the application rate. We use extra fertilizer to make up for the fertilizer that doesn’t make it to the plant due to the straw, so we may double the application rate or apply every 7 days until a week before the garlic scapes come. Water/rain will help the fertilizer make its way into the soil. The nutrients will be there for next season too helping build good nutrient rich soil. We never remove the straw. We want the weed suppression and moisture control!

Need a good fertilizer? Check out our Top Selling Organic Fertilizer! This will provide the nutrients that your garlic needs to yield nice large healthy nutrient-dense plants.

Twin Garlic…is this normal?

Twin Garlic

Thanks for the question! This is two garlic cloves that were planted together. Sometimes we don’t even notice that there could be two garlic cloves in a wrapper. This is most common with Rocambole Garlic.

When you harvest, you will have two garlic bulbs but where they come together they will be flat. They are misshapen, but still delicious!

I harvested my garlic this spring…why does it look like a green onion? I was expecting a bulb of garlic.

Green Garlic

Great question! Most of us harvest our garlic in late June or July. Garlic starts to bulb out during the last 3 weeks before harvest, but until then, it will look similar to a green onion. It can be eaten in this stage as what we call “green garlic,” but wait a few more months if you want to harvest a full garlic bulb!

If you have hardneck garlic, you will pick the garlic scapes after they curl once and then the garlic bulbs start to swell. It will take around 3 weeks to develop into a full-sized bulb with cloves. See our website for more info on when to harvest garlic.

Garlic Varieties Growth

Leigh Schmidt

I planted the first-time garlic growers package in the fall in a raised bed, and have it mulched with straw. It’s coming up and looks great! One variety is much taller than the other, I’m guessing that’s normal. I’ll fertilize this weekend, but other than that do I need to do anything besides weed, leave the straw there, and watch and wait? I’m in southern WI.

Keene Garlic

Leigh Schmidt Hi! I’m sure you are not far from us! Yes, different varieties will show differently in size and shape. In the end though, many of the bulbs are around the same size. In the sampler we usually send our region a porcelain and a purple stripe. You procelian will show a nice strong hardy plant with green leaves that start to point diagonally to the sky. The purple stripe will have thinner leaves that droop a little more and appear a little weaker. That is not the case, they will catch up to the porcelains and be nice hardy plants. You will harvest purple stripes a little later. Here are some tips your other questions for spring garlic care…/5-tips-for-spring-garlic-care/

Cold Spring slows down growth?

Windy Sue Holland

We’ve had an unusually chilly start to spring here in Louisiana. Will that slow my Lorz Italian from ripening?

Keene Garlic

Windy Sue Holland Regardless of what the season tends to be, we still usually harvest the same dates annually given 10 days before or later. So it should still end up pretty close to your normal scheduled harvest date. For us, we harvest around mid-late July. We are always done by 8/1.

It is spring, and what is the best way to use up last years crop?

Cody Hiemke

Best way to use garlic from the 2022 crop if you still have a bunch on hand?

Keene Garlic

Cody Hiemke I would try to plant some if you can. I will share our blog on spring planting. Even if they end up providing you green garlic to eat, that would still be awesome. If they are still edible, I would make them into garlic powder which will be the best you have ever had. You can freeze the cloves and use in recipes later. They will not last much longer, so now is your chance to use them or lose them. Here are some ideas…

My Garlic plants got damaged, can they be saved?

Geraldine Miller Martin

I plant my garlic in garden beds. My dog recently jumped in and sat on garlic leaves and bend them and broke a few. About 10 total. Are those bulbs doomed?☹️

Keene Garlic

Geraldine Miller Martin Lets let them keep growing. Depending on the amount of damage, garlic will try to spring back and grow. You could give them a compost tea or foliar feeding at night to give them some nutrients to want to keep growing. If they are not going to make it, harvest them and use them as green garlic which is delicious. Here are some ways to use them, if you have to harvest them.

Most Potent Garlic for Southern States

Pete Poulakos What is the most potent variety of garlic can I grow in south carolina?

Pete Poulakos SC can be a bit harder to grow garlic depending on your microclimate. You may even want to cold stratify your garlic before planting. I think all homegrown heirloom garlic is so much stronger than found in grocery stores. I’ve also learned that everyone’s concept of “potent or strong or hot” is very different. The varieties that grow best are softneck garlic varieties, turbans and creoles. Creoles are known to be very strong, but small bulb that pack a strong flavor. Lorz italian softneck is known to be hot. Here are a few more that grow well…/warm-region-garlic-from…/

    Our garlic has grown well through the spring and we are fertilizing and watering as your site suggests. I am concerned that the tips of the leaves are a bit yellow- what are we missing or what should we change

    Thank you
    MD 1st time grower

    • Keene Garlic on May 22, 2021 at 10:19 am

      Yellowing leaves could be a number of things from too much water, cold damage (common this year), nutrient deficiency, or disease problems. Many times, yellow leaves are normal and are non-concerning. I would recommend foliar feeding with compost tea or our Purple Cow CX1 and Supercharger. Here is some info on foliar feeding

  2. Kristen Frank on July 16, 2021 at 2:38 pm

    It think that we had voles in our raised garlic bed during the winter; garlic cloves/bulbs were moved around side to side and the bulbs were deeper than I had planted them, there also seemed to be tunnels. How can I repel voles while at the same time covering the garlic with 6″ of chopped leaves for insulation? I have planted garlic for many years and have not had this problem before.

    • Chris on February 23, 2023 at 10:35 am

      Kristen, may I ask what you did about the voles? I have them as well, but only the last 2 years, out of 20 in gardening! I feel like I’m going to lose my mind as they’ve taken out some of my favorite vegetables, amd you don’t know because they eat from bottom. Up and leave enough that the leaves don’t give any indication of damage! 😫

  3. Pete poulakos on September 20, 2021 at 9:08 pm

    Does the height of the garlic mean anything. My garlic grew to the hieght of 48″ to 54″
    The bulb size average between 2-1/4 to 2-3/4″.
    This has happen 2 years in a row in Missouri.
    Years prior in ohio the average was 36″ to 40″

    Can I grow garlic in a patio pot

  5. Jim Lauck on May 31, 2022 at 7:59 am

    Will Rose de Lautrec and Chamisal be available for the fall?

  6. Ken Roberts on July 25, 2022 at 4:36 pm

    We just dug out our garlic. There were earthworms in the roots. Not a problem, just wondering if you had seen this?

  7. Sue on August 19, 2022 at 3:43 pm

    I bought cloves from you last year and didn’t plant them. Is it okay to plant them this year? Haven’t done this before…

    • Bruce Reed on August 22, 2022 at 7:53 am

      It’s possible but may be recommended to get new seed stock for a successful harvest. Please inspect them carefully and look if the cloves are showing signs of deterioration or going bad. If you don’t find any it could be a worthwhile experiment to plant them. While garlic can be cured and preserved for longer storage it is a fresh product and typically does not last over 1 year unless certain measures are taking to extend the life.

  8. Keene Garlic on November 3, 2022 at 2:32 pm

    Garlic does sprout if the fall temps are too warm. They will regrow and depending on your weather they may just stay dormant and green until it warms up or they may die back and regrow in the spring. Our goal in the fall, is the get roots established with a little sprouting. We prefer not to see green growth as it puts energy into re-growing again in the spring. You will still have a nice harvest both ways.

    Hi folks –
    I grew Spanish Roja garlic for 22 years and then got hit by rust. I rested my soil for 3 years and am getting started again. No other garlic can match the Spanish Roja in my book.
    I know you are out of stock now, but can you put me on a wait list, or let me know the date that I can successfully order the Spanish Roja. I’m looking for 2 lbs. So I am not a commercial grower, but a garlic lover for sure.
    For 15 years we had our annual “garlic braiding party.” If you can help me out, I’ll invite you to # 16. True story! joe sevilla Carpinteria, CA

    Thank you!!! js

    I’ve been harvesting and eating wild garlic here in Northeast Oklahoma for 15 plus years now. It’s absolutely delicious. Would you have an idea of what type of garlic it is? What steps, if any, could I take to improve the size of the cloves along with the overall health of this wild garlic?

  11. Earl Horn on July 27, 2023 at 12:26 pm

    We’ve had an incredible amount of rain here in SW New Hampshire this summer… we recorded over 20″ in a 30 day stretch. (We’re glad that we’re just home-use gardeners who are high and dry… many river bed farmers have lost everything.) Prior to the rain our fall-planted garlic, which had 6-8″ spring leaves, was subjected to two days of 90F+ heat, followed by a mid-May deep freeze (22F), and another two days of 90F+ heat. We tried to read the heat and cold damaged garlic leaves, and finally decided to harvest far earlier (July 18 and 27) than usual (mid-August). 75% of the crop made it, but a significant amount of rot occurred. A few bulbs have nothing to salvage, but several have cloves that have just started to discolor at the tip. We’ll use some of the cloves right away. Do you have any suggestions for how to salvage those cloves for use into the fall and winter? Thanks!

  12. Missy on October 6, 2023 at 6:08 pm

    I am getting ready to plant our garlic for next spring. Do we need to rotate the crop from where we grew our garlic last year?

  13. Padilla, Manuel on October 18, 2023 at 3:32 pm

    Can I use dry leaves instead of straw to cover my new garlic bed?

  14. Tori on April 15, 2024 at 3:46 pm

    First time garlic grower here. Planted in raised beds in the fall. Did the whole fertilizer soak and all that. Covered them in straw for the winter. I am just outside of Denver, Colorado. It is now spring, 80 degrees today but, we could have snow up to Mother’s Day. Do I leave the straw over it and just fertilize and water like usual or take the straw off? Thank you!

  15. Suzanne Robbins on May 26, 2024 at 12:56 pm

    I planted garlic for the first time last fall. I have been watching for garlic scapes but have not seen any. The plants look good otherwise. Will I still get bulbs if there were no scapes to snap off?

  16. Margaret Reed on June 24, 2024 at 10:50 pm

    I planted 68 cloves of Music. Just now harvested and most of them are beautiful. However, 12 of them never scaped and have a single “clove”. Half of those 12 are firm but about half are soft and feel like wrappers. Did I do something wrong? Or is there something wrong with the variety? I hope it’s a fluke as I really love this variety.

  17. David on July 15, 2024 at 5:54 pm

    Harvested my garlic for the 2nd year in a row. After drying out, and finally using some. The cloves look translucent? Are these still safe to eat/cook with and why did this happen?
