Why is seed storage so important?

Seeds are living things! If you purchase seeds that you decide not to germinate and grow in your Rise Garden right away, it’s important to store them in an environment that does not decrease their germination rate. 

Germination rate = the rate by which seeds are able to sprout

The genetics of the seed determine its initial germination rate. But, if stored improperly, the germination rate can lower over time. 

From the time of purchase, if stored properly, your seeds will last ~1 year before you see a significant decrease in germination. After that, their germination rate decreases to the point of complete failure.

What’s the best way to store Rise Gardens seeds?

Ideal

30ºF - 40ºF, with very low humidity (~20%), and in complete darkness.

Tolerable

20ºF - 30ºF, with some humidity (~40%), and in low light.

Dangerous

40ºF - 70ºF, with high humidity (~60%), and in direct light.

What factors impact germination?

Temperature

Seeds have built-in activators in their genetics to help with the germination process. If seeds are stored at temperatures above 40ºF, these activators can stop working correctly. Similarly, if seeds are stored below 30ºF, the seed coat (the outer coating of the seed) and other organs in the seed can also be frozen and broken down, which will also impact germination rate. So, it’s important to store your seeds in an ideal environment. 

Humidity

In order to germinate, seeds need to absorb water to start activating a cascade of internal chemicals that lead to growing the first sprout. If humidity levels go above 20%, the seed may start to absorb water from the air, which would start the germination process prematurely. So, it’s important to store your seeds in a relatively dry environment.

Light Exposure

Just like water, sunlight is necessary for germination and for healthy plants. So, it’s important to store your seeds in a relatively dark environment.

Where should I store my seeds?

The best location to store your seeds is in a refrigerator! In a refrigerator, the temperature and relative light exposure are both low and consistent. 

You can also store your seeds in a cabinet (like the cabinet in Family Gardens), where it is dark and temperature is consistent. Additionally, it is best to store your seeds in their boxes, as this protects them from light and prevents them from tipping over (your seeds could accidentally fall out!).
