You can, but I’d rinse it first. I wouldn’t put too thick of a layer, but it depends on the type of seaweed. Eelgrass breaks down quicker than rockweed which likely won’t be completed brown down in spring. I usually add seaweed to my compost instead of directly to my soil. – Niki

Good question! I wouldn’t put the fabric bags on top of the bed as they garlic may sprout a bit this autumn. And it will come up early in the spring and having the bags on top may impede their growth. I’d put them to the side of the raised bed. – Niki

Hi Bill.. I saw the earlier post, but some of the info was missing so I couldn’t understand. But this is great! Glad you reposted. If the bottoms of the pots are open to the air, I would try to insulate or wrap them in some way – bubble wrap is great!! If you can, do allow a space for drainage. For example, if you’re wrapping the bottom in bubble wrap, leave at least one drainage hole exposed so any rain/snow can drain away. Or cover the bottom with a layer of straw wrapped in burlap. That is self draining. As for watering, keep the soil evenly moist until the ground freezes. At that point, deep mulch the top of the container and cover with a piece of row cover or burlap, or a piece of fabric. Something that will still allow moisture to enter and air to flow. I would also wrap the sides in bubble wrap. We do have an article on growing garlic in pots – https://savvygardening.com/how-to-grow-garlic-in-pots/. Good luck and let me know how it goes. Niki

Hi Mike, your garden beds sound awesome! It sounds like your covered RB’s stay on the warm side, even in winter. Garlic does need a cold period of about 8 weeks in order to initiate bulb formation. I suspect that is the problem. Water is also essential – garlic cloves form roots in autumn and need water until the ground freezes. They shouldn’t dry out over winter. In early spring, growth begins once again and if the soil is dry, the plants will be stunted or die. Good luck! Niki

Hi Brenda, So nice to hear from you! Seaweed is wonderful and I would prefer that over straw. As it breaks down, it enriches the soil and also keeps away slugs. Hope you enjoy a bountiful garlic crop! – Niki
