The answer depends on whether you’re planning to plant the dahlias in your garden in full ground or in pots and containers. Besides that, it is a personal choice how many Caribbean Fantasy dahlias you want. Do you like simplicity, or do you like the showy effect?
To make a nice display in your garden, we suggest keeping in mind that you need to:
• plant smaller Dahlia tubers approximately 15-18 inches apart from each other
• larger Dahlia varieties 22-26 inches apart
For Caribbean Fantasy we recommend a planting distance of 18 inches. Now you know how far apart you should plant the dahlia tubers, you can measure your garden and calculate how many Caribbean Fantasy Dahlia tubers you need.
For pots and containers, you’ll need a 12-14 inch pot for one Caribbean Fantasy dahlia tuber. So if you want more dahlias in one pot, then use a bigger pot. And it’s up to you if you want one dahlia per pot, or if you want multiple dahlias per pot.
