If this is the first year of your
Lambsquarters outside as a new plant, then it may need a little extra tending during the coldest months of the year. Not only can frost more severely damage a first-year
Lambsquarters, but it can also prevent it from growing back as a healthy plant come spring. This plant needs to be kept at 40℉(5℃) or above when they’re not yet established, which can be done either by bringing your
Lambsquarters inside for a month or two, or putting up mulch or fabric barriers that protect from frost damage.
It’s also a good idea to plant
Lambsquarters in a shadier spot during the first year or two, as smaller and weaker plants have a more difficult time maintaining their own temperatures in the heat. First-year
Lambsquarters should receive no more than five hours of direct sunlight per day, particularly if the ambient daytime temperature gets above 80℉(27℃). Shadecloth and frequent watering or misting are the keys to summer heat control.
