Slugs

Posted: 11/05/2014 at 18:46

Nematodes are microscopic worms which you water on the soil and are completely safe.  In fact, there are nematodes in your soil anyway, but 'Nemaslug' (the one to google for) just adds lots more which will kill any slugs in the area where you water it in.  It doesn't kill snails though, so best go out with a torch at night to see whether it is slugs or snails (or both if you are unlucky!)

Do be aware that other things may be to blame though, including squirrels, birds (esp. pigeons) and rodents.

Talkback: How to plant dahlia tubers

Posted: 11/05/2014 at 15:15

Hi Allison, best to[ leave it where it is - lifting now won't help it at all.  Watch for slugs and snails though - if it does start growing they will eat the shoots overnight (and may already be doing that!)  Separated dahlia tubers won't produce shoots - those only appear from close to the base of the old stem in the centre.

Those sound like scale insects, specifically one called 'brown scale':

They can take any amount of pruning and even be cut back to near the ground and will grow again. 

Brown leaves on magnolia

Posted: 11/05/2014 at 12:44

Two of my young magnolias had all of their young leaves killed by the frost a week last Friday so I would say your suspicions are completely correct.  The good news is I can see some buds which seem unaffected and there are signs of new growth beginning at the base of the dead, brown leaves.  Only time will tell, but I think magnolias are quite tough trees and should recover, although there may be no flowers next year.  Two of my others were also affected but to a much lesser extend and only a third of the leaves were partially damaged by the frost so I'm not at all worried about those.  I'm going to snip off the dead leaves, leaving a short bit of leaf stalk which will fall off by themselves in time - I don't want to risk damaging the new growth at their base by pulling the dead leaves off.

sharp sand

Posted: 10/05/2014 at 22:07

Sharp sand has lots of different grain sizes and bits of small grit and looks like this:

Builder's sand is much finer, more uniform in grain size and usually a darker brown colour.

I tried nervosus a few years ago and agree with what it says in Dove's link.  I found it a weak grower - it then died on me just as it started to look as though it was doing ok.

Hi Alan, yes mate - I always buy sharp sand from builder's merchants as it's much cheaper than GCs.
