Question: Indications for sowing


Hello,
my name is Gianluca I bought some seeds of: Ficus Seeds (Ficus Benghalensis) and Juniper Seeds (Juniperus Chinensis). I wanted to ask you for directions to obtain safe results in the sowing around: the pre-processing of the seed (glass with damp cotton for a week for example), seed depth, quantity of water before the shoot, sun exposure, temperature, vessel coverage for contain moisture up to the shoot.
I thank you in advance

Answer: Indications for sowing


Dear Gianluca,
when buying seeds of a plant without knowing the method of sowing, it is advisable to try to understand what would happen to those seeds in nature, so as to try to reproduce the event in our garden or in our greenhouse.
The ficus benghalensis is a large tropical tree, whose fruits (of small figs) would fall to the ground, in a hot and humid climate, and would germinate where they are, at most they can be eaten by some bird, which would then lay the seeds in the his droppings, some distance from the tree from which he took the fruits.
So, with regard to these seeds, which in their natural life would always have a climate that is always warm and humid enough, I would simply sow them in a seeding tray, which will be kept in a bright place, but not with direct, warm sun. very humid (try to think about the conditions at the feet of a huge ficus benghalensis).
For the Japanese juniper, things are very different, its woody fruits fall to the ground, and remain in the fresh and moist soil during the winter months, and only in spring they sprout, to give rise to new seedlings, which if they germinated in autumn would come then killed by the rigors of winter; It is therefore very probable that the juniper seeds are covered by a protective cuticle, which prevents the water from penetrating them, so that the seeds can spend an entire winter without rotting or ruining.
So, in this second case, before sowing the juniper seeds, you will have to put them with a little wet sand in a plastic bag and in the refrigerator for at least a couple of months; or you can pass them with sandpaper, to thin the cuticle, this operation is however quite delicate, if you have a lot of seeds, try the two methods: some put them in the fridge for a few months, others pass them lightly with thin sandpaper and put them in the fridge just for a week. Before putting them in the fridge, dust them with a copper-based fungicide to prevent them from developing mold.
The sowing of both seeds takes place in the same way: get a tray that is not too high, with holes in the bottom; fill it with peat and sand in equal parts well mixed and wet the mixture, possibly putting the water in the saucer and making it rise by capillarity up to the surface of the ground.
When it is well moist, place the seeds on top, well spaced (as far as possible) and let them stick to the ground with your fingers; you can cover them with a little soil, or with vermiculite, or leave them on the surface.
Cover the tray with plastic wrap, which will keep the humidity for the first week after sowing; keep the tray in a warm and bright place. Water regularly with a vaporizer, or putting water in the saucer.
