In a previous post I explained pinching out dahlias restricting plants to no more than five stems.
Too many stems diverts the plants energy into doing too much.
The same happens once blooming gets underway in earnest. The first blooms arrive atop strong sturdy stems, marvellous!
Then weeks go by and your stems seem to become progressively weaker, snapping under the strain??
What’s happening is the plant in its hurry to complete its life cycle is producing as many flowers as it can.
The heat we have been experiencing means a problem typical in Autumn is happening from the ‘get go’!
So what can you do…
Here you can see a Karma Chocolate Dahlia with the main flower bud and then two smaller buds.
Left unchecked, all 3 buds will open.
The lower flowers won’t have stems long enough to use and the strain on the plant will reduce the quality of prime flower.
It makes sense to pinch these flowers out, leaving the main bud to go on and produce a magnificent single flower!
