I'm hoping that using a Popsicle tray I can freeze 6 cloves of garlic and once removed transplant them into an indoor garden.

Would a fridge freezer be cold enough to trigger the budding process in garlic? If so how long would they need to stay in there for?

How large would the Popsicle cone need to be to accommodate the roots growth experienced during freezing?

If its dependent on the type of garlic please let me know the differences.

  • I had one garlic bulb surface from the first watering because the soil was too loose, and didn't notice it, so I can see it developing, and I'm at 2 visible cloves right now. – black thumb Apr 23 '16 at 21:00

You can just buy a clove of garlic from the store. No need to freeze it. Just break apart the cloves and plant them. They will grow indoors but require the much higher light levels that outdoors has.

If you do not provide the light levels that usually come with High Pressure Sodium or other indoor hydroponic lighting then their "growth" will be using up the stored energy in the bulb.

Having tried this in window sill light you can get a stalk over 12" tall that dies afterwards.

  • can you grow garlic year round outdoors? What are the temperature range expectations for Garlic to survive outdoors? – JStorage Mar 10 '16 at 18:37

    This should be a new question – kevinsky Mar 10 '16 at 18:39
  • Some people recommend against using store bought garlic as it may be from China, and may have been treated to stop it germinating. I did plant some cloves from some Chinese garlic that was sprouting but it didn't grow that well. But it may have just the time I planted it. – Graham Chiu Mar 11 '16 at 1:28

Some people put their garlic in the fridge for about 2 weeks. You aim to get a temperature of about 4 - 6 deg Celcius, so your fridge might not be cold enough. Some people have reported that garlic stored in the freezer sprouts just fine. It may be that they used hard neck varieties which are more suited to the cold since they originated in the cold climate of central Asia. Soft neck varieties were developed from the hard neck. However, garlic is normally planted below the frost line outside.

When garlic is in the ground before winter, it does grow roots which help prevent frost heave but that is not going to be an issue for 2 weeks in the fridge.

Budding doesn't need cold temperatures though as garlic planted in spring does bud too in temperate climates induced by the increasingly longer days, but you'll end up with smaller bulbs by the time it's finished.

When people grow garlic inside, they do that to eat the greens and not grow bulbs. To grow bulbs inside you're going to need either a sunny window with all day sun or artificial lighting. And you'll need a pot that is about 1 foot deep.

Garlic can also be grown all year round in temperate climates. We normally plant the cloves on the shortest day of the year and harvest on the longest day. I planted mine late last year in late spring into pots and pulled them out in late summer. The bulbs were just a bit small, though. And I had a problem with onion aphids which may because I used a potting mix high in nitrogen.

Just grow sufficient garlic and even without the fanciest storage (ie, not a super-cold refrigerator with controlled humidity and ventilation like the commercial producers use) you can eat it year round. As the year winds down toward next year's garlic harvest I do have some losses in storage, but I can always get usable garlic.
