Planting onion and pea seeds deeper into the soil: why and how

Sowing time is the 50% determining the final harvest. If you sow too early, the seeds may simply freeze in the ground, and if you delay, there's a risk that the seeds will either dry out or be less fertile. After all, every gardener wants a full harvest.

It is important not only not to miss sowing dates, but also the quality of the seeds, their sowing depth, and placement in the garden. Different crops are planted at different depths. The most popular for sowing in the garden are peas and onions. Which peas or onions are planted deeper into the soil and why?

Why is depth important when sowing?

Sixth-grade biology textbooks explain which pea or onion seeds need to be planted deeper into the soil and why. Schoolchildren often ask this question on tests and quizzes. The importance of planting depth for various crop seeds will be useful to learn not only for those in school but also for those who are serious about gardening.

The depth at which seeds are planted is important because the size of the seed determines the amount of nutrition nature has stored for it. For example, bean seeds have a large supply of these nutrients, while poppy seeds and other crops, on the contrary, have very little. This raises the pressing question: which onion and pea seeds are planted deeper into the soil, and why?

To answer this question, it's important to determine whether the plant is a monocot or a dicot. Monocots do not bear cotyledons to the soil surface, while dicots do.

Speaking of which, Which crops need to be buried deeper?, there are a few more nuances to consider. For example, rich grain requires being planted as deeply as possible. If the planting depth isn't sufficient, pea seeds, for example, will be visible, which could lead to attacks from birds and other animals. However, if you plant onion seeds at the wrong depth and plant them too deeply, the seeds simply won't be able to find their way up and will rot in the soil.

This suggests that larger seeds have more strength and energy to sprout through the soil layer, meaning they can be planted deeper. Furthermore, such seeds contain sufficient nutrients, so they won't starve to death at great depths.

It's also important to note that the depth at which seeds are planted depends not only on their size but also on the soil type in the area. For example, sandy soil is suitable for sowing small amounts of seeds deeply. However, heavy loam soil allows for sowing large amounts of seeds, but not so deeply. This principle is easily explained: sandy soil has too little moisture in the upper layers for proper seed growth and development.

Because pea seeds contain more nutrients than onion seeds, their seedlings are more viable. Each crop has its own reserve of nutrients, which they actively use after sowing. Therefore, both peas and onions should be sown so that by the time the seeds are depleted, the crops already have their green leaves.

Small onion seeds should be planted to a depth of 2 centimeters, and pea seeds should be planted twice as deep, that is, from 4 to 5.5 centimeters. How to organize excellent a garden for lazy people.

If you plant the seeds at the right depth and at the right time, you'll soon have a healthy, and most importantly, abundant, harvest! However, if you ignore these important planting rules, you may never see any fruit. It's not for nothing that biology classes devote a separate topic to this.
