Right at the end of last year I wrote something about fast growing annual seeds. The truth is that if late fall and early winter cold weather arrives; any plant in an early or mid stage growing phase development will slow down dramatically its metabolism and will not grow due to the absence of heat. Here in the city it happens from mid November to mid February approximately. After that date the heat booms again and everything goes back on track.
For that reason annual flowers must be sowed twice a year. At February’s last week I begin sowing the summer seeds. Ideally those plants will be ready for transplant by the first or second week of May and will be there until mid November.
Then, when mid August is here I sow the fall season seeds and they will be ready for transplant by October’s last day or first November’s week. August is a hell of a weather here. So I start my seeds indoors.
Using that approach the seedlings get enough time to become big bushy plants on both seasons.
