How long soak seeds before eating?
Soak your nuts and seeds anywhere from 20 minutes to 2 or 3 hours, or even overnight in the refrigerator. In general, harder nuts will take longer to soften.

Why do plants scatter their seeds?
Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.
What does it mean if seeds float in water?
Seeds may float because they lack viable embryos or nutrient stores, making them less dense than “good” seeds that sink in water. Or, they may float because they have air pockets inside, which don’t always affect seed vigor or viability. The only sure way to test germination is to use the coffee filter method.
Which seeds can float on water?
Seeds dispersed by water are contained in light and buoyant fruit, giving them the ability to float. Coconuts are well known for their ability to float on water to reach land where they can germinate. Similarly, willow and silver birches produce lightweight fruit that can float on water.
Will old seeds germinate?
Seeds that are only a year old, or slightly older but whose packets are still unopened, generally germinate nicely. If they’re several years old, the packs were opened and/or the seeds were stored in less than ideal conditions, subject them to a germination test. … Viable seeds should sprout by day ten.

How can you tell if a seed is female?
If what you’ve got is a handful of seeds, it’s pretty much impossible to tell which ones are male or female. The only way true way to tell the plant’s gender is to plant some seeds, then wait. After a period of several weeks, it will begin to pre-flower, or form a small bud in the crux of a branch.
