I did not expect to be writing an update so soon as I thought it would fail or at least take longer. Most of my ‘experiments’ are planted out in raspberry or strawberry punnets; there are two good things about that, one is I don’t use up my real pots and two, the plastic is see-through so you can see what is going on and also they are free with raspberries (three; three good things – no one expects the Spanish Inquisition)
I planted the peanuts on the Saturday (Experiments in Peanut) and then was watching for signs of growth. I remembered I could see through the bottom of the container so looked expecting to see nothing and was surprised to see the first evidence of a root. So I took some terrible pictures.
That was Monday and below Tuesday:
They say when the crack appears in the soil then that is when your peanut is germinating. I guess that is for people who don’t have see-through containers.
The peanuts swelled and grew super fat roots (I guess I knew this happens to almost all seeds but this seemed extreme)
Then something happened that I didn’t expect; the peanut started lifting up out of the soil
I guess as I sowed them laying sideways maybe they want to be point end down (where the knobby bit is) that is where the root has come out.
The rounder end seems to be where the leaves will come out.
Then the peanut split in half and grew further out of the soil
I took the biggest (most progressive) and repotted them and then dug up the rest to see what had happened.
It seems that the biggest peanuts germinated first and even the ones that were in shells had germinated. The first to germinate was the one I damaged slightly when I shelled it but that could have been a coincidence. The only one that didn’t germinate at all was the control peanut that was still in its shell with no cracks.
So if you wanted to save time you could just cut some slits in the shell, however I opened one that had grown the most and found that the other peanut had sprouted and was trapped inside.
So in the end it was quite successful, I think that the heat mat was the thing that made them germinate so fast; however they still seem to be growing fast so maybe 20 degrees is all that is needed. I will now wait until the weather warms significantly and see if there is enough of a season left in order to get a peanut harvest.
Have you ever grown peanuts, especially in a supposedly colder climate? – this is a new plant for me so it will be a test to see if the ‘cold’ weather of London will produce peanuts.
