Thermal inertia

We had a frost last night, and it's interesting to see that it didn't freeze the ground nearest to the stone wall.   This would be due in part to the thermal intertia of the wall itself, and in part by the fact that it is backed by a solid bank of earth that will also retain some heat.

This is relevant for me, since I am looking for somewhere to plant a fig tree that is growing from a cutting.  I haven't had a lot of success with fig tree cuttings; they either die before they root or I manage to kill them if they grow.   Last year's failure was one I planted in front of a different wall, that died of thirst in the hot Summer.   Perhaps if I put the next one here beside the veg patch where I will see it, I will remember to water it.

Here is the lone surviving fig tree cutting just starting to leaf out after Winter hibernation.   I'll plant it outside at the end of May when the frosts will be over.

In my defense I do have a fruiting fig tree that I grew from a cutting.   It gave a decent crop last year, as long as I got to the figs before the wasps found them.
