Note 2 — THE SEED-BED FOR OCTOBER:
Reading edition
The heat required in October sown plants, while growing in the seed-bed, is from sixty-five to seventy degrees of Fahrenheit's thermometer. Should that temperature be exceeded in this season, they will draw up very long: but after being ridged out, more heat will become necessary; that is to say, from seventy to eighty degrees: and the same is to be observed with young plants raised in the three following months.
