Planted garlic according to Sonia’s article in the Star— early Oct. it is now up 6″ high —- is that normal, should it be heavily covered with straw ?
Fluctuating temperatures have caused many bulbs to be a bit ‘confused’ this Fall. Although this means that the bulb is using its energy to sprout instead of creating a larger root system, it will not harm it. As the temperatures drop, the growth will stop.
Mulching (leaves, straw) is a good idea to avoid the effect of constant freezing and thawing. For further information, take a look at the following link from University of Minnesota on mulching: https://www.extension.umn.edu/distribution/cropsystems/dc7317.html
Good luck with your harvest!
