Obtaining Seeds
Getting seeds is quite easy. You can either press the fruit towards the side of a glass bowl the fill the bowl with water. The fruit will float while the seeds sink. Scoop out the fruit. Place a coffee filter in a strainer and gently pour the water in. The coffee filter and strainer will prevent the seeds from seeping through.
The way we did it however, was a little bit more simplified. Whenever we ate raspberries or blackberries we had a paper towel handy. Anyone who has eaten these berries know that you get a lot of seeds stuck in your teeth. Gently remove the seed with your finger and wipe it on the paper towel. Leave the seeds overnight to dry. Place a coffee filter in a strainer and gently pick off the seeds. Rinse the seeds.
Growing Seeds
The seeds need to be stratified. Place them in a plastic bag in the refrigerator for at least a month. When you are ready to plant the seeds they will need to be scarified first.
- Get a large sheet of sandpaper and place the seeds on.
- Fold up a corner and rub the seeds between the 2 sheets.
Experiment
We will be doing an experiment when it comes to growing these seeds. I found this method to soften the outer part of the seed by soaking them in bleach for an hour. Then add 4 cups of water for every tablespoon of bleach used. Using the coffee filter-strainer method, drain the seeds. In a large bowl add 4 tbsp of baking soda and 1 cup water. Soak the seeds for a few minutes to neutralize any remaining bleach.
For the experiment half the seeds were soaked, while the other half weren't. For the blackberries, half of both kinds were planted in seed starter, while the other half are going to be in a paper towel. The raspberries were only planted in seed starter.
We will see if soaking the seeds in bleach will make their germination time any sooner.
I have heard anywhere from 4 weeks to 6 months for the seeds to grow so we'll you up to date.
