|I have started two packs of Marigold Crackerjack Mixed Colors inside in potting trays. There is no information on how wide the plants will grow. It does say they will get 2.5 ft. high. I am wondering how far apart to space them when I transplant them outside.
|This is one of the taller, more erect varieties, so spacing would depend on what sort of look you prefer -- a relatively close spacing would be about 16 inches. Crackerjack may actually grow to 36 inches under ideal conditions.
