【Useful for All Seeds】How to Break Dormancy and Germinate Peach Seeds in the Refrigerator

Sprouted peach seeds

This time, I’ll share a unique example of germinating peach seeds while breaking their dormancy.

In fact, I’ve come to believe that this might be the best method for dormancy breaking.

So, let me introduce you to the method of breaking dormancy and germinating peach seeds in the refrigerator.

 

Save the peach seeds after eating the fruit

To germinate peach seeds, you first need to collect the seeds.

Once peaches start appearing in stores, buy some and enjoy them. After eating, save the seeds carefully. This completes the preparation for peach seeds.

The flesh of peaches contains germination inhibitors, so be sure to wash off any remaining flesh from around the seed thoroughly.

Although it’s possible to store just the peach seed without the shell, I found it easier to keep the seeds in their shells, as my attempt to store the bare seeds led to rot.

Wrap the peach seeds in a damp paper towel to keep them from drying out, and store them in the refrigerator

After washing off the peach flesh, store the seeds in the refrigerator to induce dormancy.

Peach seeds’ germination rate decreases if they dry out, so wrap them in a damp paper towel, place them in a plastic bag, and store them in the refrigerator as shown in the photo.

How to Break Dormancy in Peach Seeds
  • STEP1
    Wash away any remaining fruit flesh from the peach seeds thoroughly.
  • STEP2
    Wrap the peach seeds in dampened kitchen paper towels
  • STEP3
    Place the peach seeds in a plastic bag and seal it tightly
  • STEP4
    Store the peach seeds in the refrigerator

The method to break dormancy in peach seeds follows these steps:

The key is to wrap them in dampened kitchen paper.

As long as you adhere to this, you should be fine!

 

After allowing the peach seeds to dormantly rest in the refrigerator for about two months, remove them

Dormant peach seeds

Here are the peach seeds that have completed dormancy.

Out of the five seeds I rested, one had its shell removed, while the rest remained intact.

    • Seed without shell: Rotted and became mushy
    • One seed with shell: Unpleasant odor upon removal with shell became soft and deformed

Unfortunately, I had to discard them due to their condition.

It’s important not only to avoid drying out the seeds but also to manage humidity, which I neglected, resulting in two seeds rotting.

Now, take a look at the seed on the right.

It has already sprouted.

Although I intended to let the peach seeds rest until spring to avoid the hassle of managing them during winter, they completed dormancy and sprouted in the refrigerator sooner than expected.

It’s an unexpected delight, and for now, I’ve successfully managed to germinate at least one seed!

After one week from sowing the peach seeds, sprouts emerged

Sprouted peach seeds

It’s been a week since I planted the peach seeds.

Sprouts have already emerged from the ones that had germinated!

I was a bit concerned about the direction of the roots since I planted them after germination, but they emerged just fine.

Also, I checked that the other seed has also germinated and is extending its roots. Out of the three seeds, two have successfully sprouted, making for a promising start.

It’s been 5 months since I planted the peach seeds, and they’re growing rapidly

Peaches 5 months after planting

It’s been 5 months since I planted the peach seeds.

Out of the three seeds I planted, only one successfully germinated and has been growing vigorously.

After transplanting it into a pot, its height, which was only about 10cm initially, has now reached around 50cm.

During the excessively hot summer months, growth seemed to slow down, and for the past month, it has maintained this height.

Unlike apples or pears, which grow their main trunk straight up, peaches seem to grow with spreading side branches, giving them the appearance of a well-established tree already.

The recommended method for breaking dormancy in fruit seeds is to wrap them in dampened kitchen paper towels

This time, when attempting to break dormancy and germinate peach seeds, they had already sprouted inside the refrigerator.

Interestingly, I had also wrapped pear and apple seeds in dampened kitchen paper towels and stored them in the fridge, using the same method as the peach seeds.

Apple seeds sprouting in the refrigerator

This is a type of apple seed called “Aki-ake,” but it had already sprouted inside the refrigerator, resembling bean sprouts.

I’m not sure when it started sprouting, but it has long roots and appears to be growing a bit spindly.

Pears sprouting in the refrigerator

And here we have the seeds of a variety called “Shinko,” which is a type of pear.

Like the others, it had sprouted inside the refrigerator, but it seems like it hadn’t been sprouting for too long. It’s not growing too spindly like bean sprouts, so its condition seems fine.

Both of them are currently transferred into pots and are showing their true leaves, growing steadily.

This time, I performed the dormancy break by wrapping the seeds in kitchen paper soaked in water inside the refrigerator for three types:

  • Peach
  • Apple
  • Pear

All three types of seeds had already sprouted inside the refrigerator. It’s not good to let them sprout unnoticed and grow spindly like apple seeds, but using kitchen paper soaked in water for the dormancy break to sprouting process seems to be effective.

Let’s try breaking dormancy and germination in peach seeds

This time, I introduced a method for breaking dormancy in peach seeds and inducing germination.

While I was also trying to break dormancy in seeds of other fruits, I was concerned that the large shell of peach seeds might hinder germination through conventional methods.

After researching various approaches, I found that preventing drying out during dormancy breaking could improve germination rates. So, I decided to wrap them in dampened kitchen paper and store them in the refrigerator.

The results were a resounding success. In fact, before I knew it, not only had dormancy been broken but germination had also been completed.

Similar success was observed with apple and pear seeds using the same method of dormancy breaking and germination induction, so wrapping them in dampened kitchen paper and storing them in the refrigerator is highly recommended.

While fruit seeds requiring a dormant period may take some time to germinate, it’s entirely possible to cultivate them and grow delicious fruits in your own backyard.

So, why not start by collecting seeds and embark on your journey to harvest delicious fruits in your home garden?
