Overwintering Convolvulus and young lavender.

Posted: 06/11/2015 at 13:41

Health warning TT.  Verdun is in the balmy south west of England and never gets anything like an Edinburgh winter.

Plants in small pots are more likely to get their roots frozen to death so pot on and take into shelter.  A window box indoors will be fine and then you can plant them out next spring when the first of the frosts are over - either in pots, troughs or your borders.

Tracking Down Plants

I have just seen these in my local garden and pet store - €4.95  for a 2 litre pot with 20% off as part of a November planting promotion - so I bought one.

Windowsill then.

How big are the pots your lavender is in?  They do need some moisture but don't like to sit in wet and, as far as I know, the pink and white French varieties (except lavendula Edelweiss) are much less hardy than my Hidcote or Munstead Dwarf which are British varieties better suited to British weather.

Consider transferring yours to a window box with John Innes no 2 or 3 compost and keep them indoors on a cool, light windowsill till next spring.

Convolvulus is not very hardy and won't cope with temps below -5C or winter wet so really needs a cool, light windowsill or frost free greenhouse or cold frame to survive. 

Lavender, big or small, doesn't like winter wet so may be OK in a light, sheltered spot where the pots won't get frozen or drowned.   I grow mine as a low hedge in full sun along the top of a retaining wall where drainage is good and they have survived -20C but, for their first winter, they had had an entire summer season to grow big enough to cope.  I lost about 5 that first winter - Hidcote variety - but the rest and the replacements have survived and thrived since.

Annual Cosmos

They're annuals - germinate, flower, seed and die in one year.  You'll need to sow new seeds for next year.

Bay doesn't do well in cold winters so I'd go for apple.  There are plenty suitable for growing in pots if you buy one on a dwarf rooting stock but you need a pollinator to get apples so may have to buy two.  You can also buy "family" trees which have 2 to 4 pollinator compatible varieties grafted on one root stock.

Have a look at these sites and ask questions of them before choosing and ordering:-








Planting a conifer - help on selection

Posted: 05/11/2015 at 15:39

Liquidambar Slender Silhouette is recommended as a slender tree for smaller gardens.    Needs acid soil and some moisture for best colour.   It will take 50 years to get to full height.

Issues with a Leylandii Conifer

These things won't recover as they don't grow new shoots from brown wood which is why they always have to be pruned or trimmed leaving some green foliage.

Get rid and plant something lighter and brighter - after lathering on generous amounts of well-rotted manure and garden compost to help replenish soil nutrients and condition.

Planting a conifer - help on selection

Definitely not a conifer.  Most heights indicated are for growth after 10 years but that doesn't mean they stop growing.

If it has to be evergreen then definitely a holly which has been around a lot longer than Xmas!   However, look also at liquidambar which is deciduous but the bare branches in winter will provide a filigree effect for privacy.   Good shape and size and fabulous foliage colour in spring and autumn so lots of interest.

You could also look at winter flowering cherries such as - https://www.rhs.org.uk/plants/details?plantid=5464 which will give flwoers in winter and good foliage the rest of the year.

Moving House with Plants

They should both be going dormant at this stage of the year so, as long as they're well packed up and have some air around their heads and don't get squished by packing cases they should be fine for a few days.

When we moved from Harrow to Belgium I brought a Japanese maple, a rhus typhina dissectum, a Worcesterberry, a pot of proper English raspberries and a few other plants in smaller pots with us - all gifts or having special associations for me.  They spent 4 days in a sealed removal truck in June and were none the worse for wear.  I still have them all 24 years later - except the acer which succumbed to a very hard winter one year.
