Germination Periods

On this site, I will collect all the germination data I have found out during my attempts to get seeds to sprout. The germination period might actually a day or two less, because I note the date I can see the soil bulge. The root might have grown from the seed earlier.

Last Update: July 10 2014

Germination of Lemon Pips

If you want to grow lemon trees from pips straight from the fruit, suck them in you mouth for a while. Only take them out of you mouth to put them into soil, not earlier.

Germination of Pomegranate Seeds

As with lemons, it’s best to get the seeds from the fruit and again, try to suck on them a bit. Otherwise, it is difficult to get all the fruit pulp off which contains sugar, which in turn would favour moulding.
