Hardwood cuttings from apple

Grafting is your best bet, steephill, but you do need another apple tree to graft onto of course.

Brussel Sprouts

Posted: 03/02/2014 at 19:11

Even if they grow OK in pots (and I'm very dubious about that), they might be more trouble than they're worth, biofreak.  Brussels are very top-heavy and unless you tied them to horizontal wires or something they would be constantly being blown-over.

Hi all, the temperature results are in.  I left it a couple of days to make sure things had settled down.

With the probe placed in the sand and showing 25C, the temperature on the surface of a tray of compost placed on top of the sand and covered with a clear lid varied over a night and a day from between 15.5C to 19.5C (measured using a mix-min thermometer placed on top of the compost.)  Clearly, the air temperature in the shed has a fair effect on the compost temperature even though the sand is absolutely constant at 25C, so tonight I'm raising the sand temperature to 30C and will report back tomorrow.

Because I have a moveable thermostat probe, in order to keep an exact temperature in the seed trays themselves, I do have the option of putting the probe in the actual seed tray rather than in the sand below and will try that tomorrow night.

 

Flatworms?

They prefer cooler areas, Verdun, so unlikely down your way.  They're not notifiable as far as I'm aware, but DEFRA are collecting info:

Thanks Daintiness!   I find gardening is really all about planning - at the very least it gives us something interesting to do in the winter or while it's raining!

Flatworms?

GM, I have read that if you put a sheet of non-clear polythene (eg an old compost bag) on the ground and weighed down by stones, NZ flatworms will congregate underneath it.  If you want to photograph them to get a positive ID then you could try that - best to be sure as you don't want to be killing any of the good guys.

Hi Daintiness, I have made a lid using the same exterior grade plywood as the base so once I don't need the heat any longer it will be turned off, the lid fitted and it'll become just a normal bench (which I'll be growing peppers on, as it happens!)

Hi Clueless,  thanks for posting that as I just realised I made a mistake in the text above - I actually used a 12m cable, NOT a 6m one!

As long as you can fit that 12m of cable into your 100cm x 80cm hot bed without any of the cable touching itself, you will be fine as long as you do use a thermostat.  It will have the advantage of heating up quicker but won't use any more electricity as the thermostat will turn it off as soon as the sand reaches the set temperature.

 

When is the best time to prune Group 3 clematis?

Posted: 02/02/2014 at 18:04

Tricky, chicky, this year!  I normally wait until the end of Feb or mid-March, depending on the weather.  Cutting them back encourages them to start shooting and there's always a danger of a hard frost killing the new growth.  If you do it now and there are no hard frosts them you'll get early blooms but if we get hit by an actual winter arriving then you'll regret doing it now.  Personally, I'm leaving mine for now.

Confused by my group 3 clematis

Posted: 02/02/2014 at 15:58

Go for that low single bud, cloud8.  I cut most of my group 3 right down to the ground and they produce new shoots from below ground level.  As group 3 produce flowers on new growth, the more new shoots you can encourage from the base, the better.
