Hakonechloa - poisonus to dogs?

Posted: 24/07/2013 at 11:48

My cats and dogs always seem to prefer the ornamentals I cultivate for display rather thatn the couch grass I could do with help getting rid of. 

They like hakonechloa, new shoots on miscanthus and so on.  Hasn't harmed them yet.

can anyone tell me what this plant is?

Ligularia needs moisture retentive soil to do well.

Clematis not flowering

Feed with specialist clematis food which is granular and slow release.  Give an instant tonic of liquid tomato food and check you are using the correct pruning regime for each clematis variety.

Ligularia - http://apps.rhs.org.uk/plantselector/plant?plantid=1155

Eremerus have strappy leaves and, as their other common name - Desert Candles - indicates, need good drainage and full sun to do well.

Rose help please

Don't feed it any more now as any new growth won't have time to ripen and harden off before the winter frosts come and freeze it to a mush.

If you can, re-plant it in a deeper pot with the graft union a couple of inches below soil level.  This will help protect it and encourage new shoots from the variety and not the rootstock.  Keep it moist but not wet and with any luck it will recover and grow.

In that case they are probably congested and need lifting and dividing to re-invigorate them.

You can do this from mid summer to early autumn while they're still green but you must water them thoroughly first and leave them to soak it up before you dig up teh clumps.  Then you can split them with a spade and replant them in well prepared soil containing lots of well rotted garden compost and/or manure to feed them and help retain moisture.  I would chuck in a couple of handsful of pelleted chicken manure too.

Once re-planted, they will need monitoring and regular watering until established, established if you do it sooner rather than later.

My pleasure.  I have some of these myself and love the rich colours of the flowers.

Iris sibirica do well in full sun or partial shade but they need moisture at their roots. 

The maple will be providing huge competition for food and water, especially during this heatwave, so water them throughly and then, in autumn when the foliage dies back, consider either moving them or giving them a very thorough mulch of garden compost and well rotted manure to retain moisture and again next spring.

Alliums with Agapanthus?

Posted: 22/07/2013 at 14:54

I would plant a contrasting leaf and flower form which allows the alliums to show of ftheir tall spikes and purple flower balls followed by the seed heads.  I have alliums coming up through hardy geraniums, hostas and pulmonaria in different bits of the garden.  

They'd look great with geums too so that's the plan for next year.  I love alliums and nectaroscordums and add more each year.

How do you keep geranium sanguineum flowering

Posted: 22/07/2013 at 10:08

I just leave my macrorhizums and occasionally dig up bits to give away or plant elsewhere as it's so good for difficult spots such as dry shade.

I cut back all the geranium phaeums and a load of un-named pink ones at teh end of June and they've already grown healthy new foliage.  Plenty more to do this week before teh rain starts agai at teh end of teh week.  They'll be looking good again by mid August.
