I put 3 seed pans in the propagator the other day. I "found" 3 envelopes of own saved seed, Salvia sclarea, Colutea..and another ??
I thought I would sow a few and keep a few and make that the start of this years sowings.
I was tidying up in the back greenhouse a few weeks ago and there was some seed on some Agapanthus heads...so I sowed a pan of them as a bit of interest...up in no time and now standing on the gravel tray with the heating wire in.
...and with ref to sap rising...several years ago I was doing some tree tidying, standardizing....and whipped a few branches off a Maple...it bled like crazy.

...that's when I learnt all about how Maples are purposely syrup bled.....on a warming day following very cold.
-7C at work at 1pm today...but really lovely in the sunshine and very warm in the front greenhouse.
Garage roof at home was "steaming" in the sunshine at lunchtime.
