Jumpstarting Your Garden: A Guide to Pretreating Seeds

How to Properly Pretreat Seeds

Introduction

It is important to know how to properly pretreat seeds so that they will produce healthy, vigorous plants. This can be done by using several different methods. One method includes sacrificing and pre-soaking the seeds. Another method involves planting and promoting growth through stratification and sprouting.

Pre-soaking and Scarifying

Presoaking and scarifying seeds is a process that can boost your germination rates. When seeds are soaked, they soften the tough outer coat of the seed. This makes it easier for moisture to penetrate the seed. If the outer coating is rock hard, it can prevent water from reaching the embryo inside the seed.

Scarification is a method of breaking the outer shell of seed and exposing the inner seed. Depending on the species, it can take different amounts of heat to destroy the coat.

Generally speaking, the best way to scarify a seed is to use a sharp tool. Among the most common methods are sandpaper and a nail file. The best part is that it's not messy.

The key is to keep the pressure light. A good rule of thumb is to avoid touching the seed itself. During soaking, the seed may sprout, but this doesn't necessarily mean it's viable.

Stratification

Pretreatment of seeds is an important step in the process of starting a new plant from seed. The process of pretreatment helps to break dormancy, the period of dormancy before germination, and allows the undeveloped embryo to begin development.

There are several different ways to pretreat a seed. You can choose to do it outdoors, indoors, or even in a refrigerator. It is important to keep in mind the time needed for the various types of pretreating.

For many seeds, soaking in water can help to shorten the germination time. It is also a good way to remove any excess moisture.

Another strategy involves scarification. This is where the hard coat of the seed is weakened. When done correctly, scarification helps to increase the germination rate of the seed.

Presprouting Seeds

Pretreating seeds can be done using a variety of techniques. Some methods involve soaking the seed in a solution that softens the shells. Other techniques involve crushing the seed and reducing the surface area.

Soaking seeds in alkali solutions, such as sodium hydroxide, potassium hydroxide or sodium chloride, can soften the shells. This can be done overnight. However, these techniques can be dangerous.

A pin-crushing device can be used to break up pretreated seeds. It requires less effort than other techniques. The device is made from a die plate with pins that engage the seed.

The die plate can be driven by pistons or hydraulics. These devices can be adjusted to keep the integrity of wells. Depending on the number of wells, the number of pins can be changed to fit the size of the seeds.

Planting

Pretreating seeds is an important part of growing plants. It can increase the germination rate of the seed and reduce the amount of work required during the growth process. This can lead to better establishment success in specific habitats.

Seeds are often categorized into two groups - those that require warm moist stratification and those that need a period of cold treatment. Some plant species need both conditions to initiate their seeds.

The first step in pretreating is soaking. A soaking of water, which is also known as imbibition, will help soften the coat of the seed.

Another type of pretreatment involves scarification. Scarification is the process of breaking through the hard shell of the seed. There are many tools that can be used for scarification.

Conclusion

The pretreatment of choice for my seed stock is the permaculture slash. With proper care and feeding the trees will be well on their way to maturity and a healthier you. As is the case with all plants a little TLC can go a long way.
