It was about 11 months ago when I described a way of calculating the optimum number of plants (or bulbs, etc) that would fit in a particular size of round pot. The method was a bit long winded though and I wanted something that would work for any circular space including a large plot. It might be quite difficult to work out for instance how many plants you would need to fill a bed of the size you get in many municipal parks. I have managed to develop a simple formula.  where n is the number of plants you need and d is the number of plants that will fit across the diameter of the pot or plot. If you get a fractional answer, take the nearest whole number greater than that. Hope it may be useful to someone. It also works in reverse.  Again if you get a fractional answer, take the nearest whole number greater than that. |

Seriously Ron, as a profesional gardener for 35 years, get your plants, do a bit of research on their eventual height and spread and bung them in.
Your equasion misses one important point....plants have different sizes so for example, you can plant 10 Lobelia in a 10 litre pot but only 5 Salvias or 1 Canna. The same goes with bulbs....i might put 20 crocus in a 10 litre but only 2 foxtail lillies
Life's too short.

d is the number of plants that will fit across the diameter of the pot or plot This takes care of the spread, andy. So it works for any plant. I can't just bung them in because inevitably when I do it goes wrong. I do go overboard with planning sometimes I suppose but hey, it takes all sorts. |
