overwintered in greenhouse - but now what?

 Hi, I have overwintered both geraniums and chrysanthemums in my greenhouse, now not sure what to do with them. 

The pots they were in are full of tulips and primroses. 

The primroses I bought last autumn in flower and thought they would of died off by now.  I have now been told that they will continue to grow and it is possible to split them to make more (any advice on how would be nice).

So do I just leave the primroses in place and buy more pots for the geraniums and chrysanthemums. 

Also can I split either of these before repotting.  I did try taking some cuttings - they continued to flower in the conservatory but have not rooted.  Maybe September was the wrong time to try this - should I do it now? 

If so, is it best to try rooting them in water or just compost (tried both in sept but neither way worked)

Thanks in anticipation


  • Hello

    To split your primroses, cut off any dead flower heads, knock them out of the pots and then gently easy the plant apart with your fingers - using splits into 2 or 3 pieces with roots attached. Plant them immediately anywhere in the garden and water. They will keep coming up for years. I split mine and now they cover the ground near the dry stone wall every spring - looks a picture.

    Happy gardening

    thanks Verdun - disappointed to hear that the tulips wont flower again next year.  will try splitting the geraniums and chrysanthemums as you suggested.


    Mrs Monkey re the primroses, should I wait until they have finished flowering?  Do you think they would be ok moved into small pots and then moved back to the large one in the autumn.  I have them in half whiskey barrels at the moment which is where I had my geraniums last summer.

    lorr, the tulips might well flower again.  All our tulips flower every year, and I have added more and more.  They are in free draining soil in raised beds, which is pretty optimum, because the most common reason for them not coming back is that the bulbs rot.  In fact, I suspect some of the bulbs have divided because we seem to get even more flowers and more closely grouped than I would ever have planted them.  So don't despair.  My chrysanths from last year have been in the beds all winter, and are still growing - I thought they were annuals, and had nowhere to save them, but they have battled on through any frosts.

    Thanks Busy Bee2

    I was expecting that they would be like daffs.  Want to try and get away from planting annuals every year.  Would like the garden to be full of plants in flower all year round if poss.

    Starting off with aconites, snowdrops, crocus, daffs, tulips, forsythia, grape hyacinth, forget me nots, then followed by a lot various other shrubs and plants that appear each year (which I am still trying to name),

    I am taking photos every couple of weeks as I notice something different appear - then can hopefully find out their names and what exactly they do and when, and if I need to do anything to encourage their growth.

    Been here over 10years and planned to do it every year but fully intend to do it this year - otherwise I will be downsizing to an OAP bungalow before I get it done lol. 


  • Hi again

    Just moved my geraniums into the greenhouse for the winter -  just wondering if it is best to cut them down, or just leave them as I did last year and let them continue to flower in the greenhouse over the winter.  Was wondering if by cutting them down they might grow even better next spring.

    Also running out of space in the greenhouse, will chrysanthemums survive outdoors or possibly in the shed?  Don't want to loose them - not at £8 a plant from Dobbies

    Leave the geraniums as they are, keep them on the dry side. Chrysanths I would lift and pop them in some dryish compost,in a box, a cardboard box will do, pop them under the staging in the GH. They'll go dormant and in spring bring them out and start again.

  • Hi Dave, Great idea about the box - do you think it would be too dark for them in the shed?

  • not sure what to do about the geraniums I have in the greenhouse should I start watering soon or cut them back to encourage new growth

    Assuming you're in the UK Carole I would leave them a couple more weeks. I usually start giving mine a bit more water at the end of Feb / beg of March when light levels and temps are starting to improve. 

    As soon as they start showing signs of stirring I repot them and cut them back fairly hard (especially if they're bit straggly) to make bushier plants. You can use some of the prunings as cuttings to make new plants.
