Garden post Ophelia

My Dahlias and Rudbeckia have all been knocked to the ground. I will have to cut them all back now as I would have done after 1st frost. Will this have adverse effect on next year's blooms. Also should I lift and store the dahlia tubers now or leave them until frost arrives?. I'm sure you will get many similar questions over next few days. DonFoley, Maynooth, Co Kildare Posted: 16/10/2017

Even though knocked over, plants that are still green continue to photosynthesise and build up reserves for next year. 

But you can leave them until frost, or lift and store, if you wish, as there is only a few weeks left in any case.  Growth continues until the soil temperature falls to 6 Celsius after a few frosts.


Dividing flowers

When should I divide my enormous clump of crocosmia Lucifer which has finished flowering? shagra, Kilmacthomas, Co Waterford Posted: 21/09/2017

When it has had a chance to build its reserves for flowering next year, divide it when its foliage yellows and turns brown.


eradicate bamboo

I unknowingly put in spreading/creeping bamboo into my garden. I now want to completely eradicate it! Last spring I removed it but it came back . I then used round up, the old strong stuff. It killed the leaves but not the roots and now I have more regrowth again. Through this soil there are loads of trade like roots and again I have more regrowth. What do you recommend I do now. Do I need to remove all this earth going back by 2 foot and replace with new topsoil or is there a less laboursome solution. I have grazeon 90 in shed evelyn1979, fermoy , Co Cork Posted: 30/08/2017

Bamboo is a grass and Roundup is the best product.

Let the shoots grow to 30cm tall and spray, and repeat this process as many times as needed until the bamboo dies out. Use a 1 part in 40 dilution.

That is Japanese anemone, Anemone x hybrida.


Day Lilies

Should I cut day lilies back after they flower? kilmoon, Sherkin Island, Co Cork Posted: 15/08/2017

Just dead-head the spent flowers or cut out the flower stems to increase the possibility of some late flowers.

  No flowers on Peony Rose

No flowers on Peony Rose

I have a peony rose in my garden for a good few years and it always flowered until last year and this year when I had plenty of leaves but no flowers what is the reason for this I include photo. Marie Jo, Youghal, Co Cork Posted: 14/08/2017

In the photo you sent, it looks dry and cramped by other plants, 2 reasons why it would not flower well.

Try mulching, reduce competition and, failing that, a move to a better spot in autumn.
