Seed Germination – Easy Tricks for More Success

| Plant, Video

Starting seeds indoors is a fun activity that helps you make the most of a short gardening season, but some seeds are harder to germinate than others. In this video, I share tips and tricks for seed germination success.



Outdoors, Mother Nature does a great job of breaking through the seed coat of tough seeds. Indoors, we can help that process along a few different ways. 

The Warm Soak

To soften their hard outer layer, some seeds benefit from a soak in warm water before planting. Simply place the seeds in a cup of warm (but not boiling) water and set them aside for 24 hours before planting as usual. 

Okra, peas, beans and nasturtiums are just a few examples of seeds that are suited to the warm soak method. 


Soaking seeds

Seeds that have a hard outer layer benefit from being soaked in warm water to soften up their seed coat prior to planting.



Scarification is the processing of breaking through extremely hard seed coats by scarring or scratching the seed surface. This allows air and water to permeate the seed so germination can begin. Only a little bit of the seed coat needs to be removed to be effective.

Take a seed and rub it on sandpaper just until you see the color change. Alternatively, you can use a file.

Some seeds, like beans, have a white dot where the shoot will emerge from. To avoid damaging the eye of the seed, scratch the opposite side.

Stratification simulates nature’s ebbs and flows of winter and early spring, as many perennial seeds and tree seeds require that temperature variability to cue them to sprout. 

Place seeds in a plastic bag with a moist (but not wet) soil mix and leave the bag in the refrigerator for about 10 to 12 weeks. When you bring the bag out of the cold, the seeds will think it’s springtime and begin to sprout.
