Pricking out Ageratum seedlings

Greetings from a new member, a refugee from the defunct Gardeners World web site, where I was a lurker for many years. I have been a suburban gardener for 50 of my 73 years, and have long ago settled into an annual routine of sowing my favourite flowers, tomatoes , roses etc, but every now and then, I try something new, in this case Ageratum, which has sprouted thickly in its trays. The seedlings have now developed their first true leaves, so I will be pricking out this coming week. Now, do I prick out individually, or , like Lobelia, in clumps together? I ask only because the pair of Ageratum trays must have literally hundreds of seedlings, all close together. I am happy pricking out individually, but don’t want to find that the resulting plants are a bit sparse. Thank you for any advice.

 

Individually for Ageratum , what variety are you growing ?

 

I grow a tall Ageratum, which I sow very thinly and prick out individually. They grow into quite substantial plants.

 

If I find I've 'overdone' the sowing, I prick out into clumps like lobelia, then thin those as and when I have time/can be bothered.

 

Thank you all for your replies. The variety is Ageratum Blue Mink, a low grower I think. I will prick out individually until exhausted, and then do a tray in clumps. Looks like there will a profusion in the flower beds this year.

 

I've started planting in clumps, when planting in their final spots I sometimes split them again into smaller clumps. I've done this with pansies, alyssum, wallflowers, poppies, borage, carnations. Have a go at doing both and see what suits you best.
