Moving azaleas and rohodendrons

Posted: 31/05/2016 at 18:31

I'm in the same position ... I have a rhody which is 10 years old now, has been healthy in the past and flowered well. It is about 2ft tall, with a very open 'canopy' but this year, after flowering, it looks very feeble and spindly. There is only leaf growth right at the end of the stems. I suspect it's undernourished so I thought I might cut a circle around it to cut through the roots and encourage more fibrous ones, then give it extra watering and plant food before moving it away from competition later on in the season. Would a rhody welcome this kind of treatment?  I might add, it's right next to another dwarf variety which is older and seems perfectly happy where it is!

Thanks for the suggestions.  Penstemon back in greenhouse - fingers crossed!

Thanks Hostafan ... I'll try that.  Any other year I'd have said March was too early as well, but it's been such a mild winter (even here in East of Scotland!) that I was worried the greenhouse was too warm for them all!   I have verbena and echinacea that were all treated the same but it's only the penstemon that has suffered.

Last year I took several cuttings from a Penstemon.  They rooted successfully and over-wintered well in the greenhouse, together with the parent plant.  During the warm spell in early March I brought them all out and put them in a sheltered spot to harden off. The result is there's a bit of die back on the parent plant and its stems look healthy, but the leaves on all the cuttings turned brown and the stems look to be dying back.  They all have a good root system, though.  Have I lost them?

Thanks, Fairygirl


Allium Christophii

Just had my first successful flowering of Allium Christophii and their seed heads are now sitting beautifully in vases in the house.  The bulbs are still in their terracotta pot - should I lift them for drying before replanting in autumn?

Thanks, Ruth - noted for next season!

Savoys and Cauliflower

Thanks, Scroggin ... I think I may give up on the caulis, then!  Will have a go at using the leaves as greens, but I imagine they'll be a little on the tough side!

Savoys and Cauliflower

Posted: 03/08/2015 at 16:20

This is my first year growing savoys and cauliflower.  They look very healthy but are very tall, with huge leaves and, so far, no sign of a heart or a curd.  Is all the energy going into the outer leaves?  Should I take some of them off?  If so, I would be left with something of a stem which might rock in the wind, and limited means of earthing them up. Any advice very welcome! Thanks.

Just caught up with this thread - didn't realise how lengthy the discussion had been!

2015 progress to date .... sowed Tumbling Tom (Red and Yellow), Ailsa Craig and Rainbow in early April in 3" pots in windowsill propagators.  All germinated, then put pots into home made light boxes made from shoe boxes with high backboards and covered in tinfoil.  All very happy on the windowsills.  Then (trying to avoid them getting leggy) I potted on to 5" pots in lightboxes and still indoors as we've had cold nights.  Now all in greenhouse, looking much happier than any of last year's lot - ready for final potting on soon.  Oh, the promise!!  Time will tell ...
