Advice on staking dahlias please

Hi all its been a long time.. I know I'm on the wrong page, I keep forgetting these things my apologies... Help needed here,,, I have looked up untold sites plus youtube etc regarding staking Dahlia's but none say how far apart the stakes should be.. Its for the dinner plate collection. I am getting the beds ready now so need help urgent please. I do realise this should be under new post but forgot how... Sorry. Anyone help me please. Plants are in pots in greenhouse doing nicely.
For anyone who remembers I tried growing 2 coconuts in November they have roots on and are now in pots again in the greenhouse... Have to see how they get on

 

Plants must be spaced from each other with a space of 80-120 cm for the taller varieties, 50-80 cm for medium size dahlias and 30-40 cm for the dwarf plants.

 

3 stakes 2ft apart should be ok.

 

Thanks Freddy you talking my language now ft and ins lol

 

When I was showing I staked mine with 5ft canes allowing 1ft 6ins into the ground to hold better in the wind.I used to grow then under covers to help keep them fresh. Growing them 2 up and 1 cane for a small plant pot filled with straw to trap any earwigs.The smaller varieties put 4 smaller canes round them and just looped twine round them,again with a small plant pot on top pf 1 to trap earwigs.

 

Jono if you are growing the big 4 foot Dahlias , I would space them as Freddy and Java recommend 80 - 120 cm , 2 to 3 feet . Its only my third year growing dinner plate dahlias and I'll be spacing at nearer 3 feet. They are a big plant ! Fileyboy has the staking off to a fine art I use vending machine cups on top of the stakes filled with straw to catch earwigs , and stop poking my eye out !

 

thank you Harry, much appreciated
