Often, even experienced summer residents are not able to accurately predict the required number of seeds. They are sometimes not enough, then there are surpluses, which by the next season lose their germination. In order not to run around in search of the right seeds and at the same time not to spend too much money, it makes sense to calculate everything in advance.
First, you need to decide how many and what kind of vegetables you want to get in the end. It is important to consider not only how much the family can eat, but also the existing possibilities for processing and storing the crop. When growing any new or exotic crop, it is better to start with small volumes. A new plant may grow poorly or just not be to the taste of households.
After that, you can use the approximate data on the yield of various crops. These are very rough indicators. They largely depend on the variety, technology, and growing conditions, and the season may vary from season to season in the same locality. In addition, no one guarantees the absence of diseases, pests, and other troubles. However, one must begin with something. These standards can subsequently be adjusted based on the actual harvest, and in the future, rely on the corrected figures.
How many bags of seeds are needed: starting from the area
So, how much and what they get from 1 square. m:
- potatoes – 2 kg early, 4-5 kg late,
- white cabbage – 3-4 kg early, 6-10 kg late,
- onions – 2-4 kg,
- carrots – 4-6 kg,
- beets – 3 -6 kg,
- zucchini – 4-7 kg,
- cucumbers – 3-6 kg,
- tomatoes – 4-6 kg in the open ground, 5-8 kg in the greenhouse,
- pumpkin – 4-6 kg,
- legumes – 1 , 5-2 kg,
- eggplant – 1.5-7 kg.
It is very good if the yield of a particular variety is already indicated on a bag of seeds.
Knowing how much is planned to be received and how much can be expected from 1 sq. m, you can calculate the required area.
Having mentally allocated a place for each crop in the garden, we can proceed to the next step – to calculate the required number of seeds. Here, too, there are averaged data.
Seeding rates for the main crops are as follows (how many grams are required per 1 sq. M):
- onions to the north – 7 g,
- carrots – 0.1-0.5 g,
- beets – 1.0-1.5 g,
- zucchini – 0.3-0.4 g,
- cucumbers – 0, 6-0.8 g,
- pumpkin – 0.2-0.3 g,
- legumes – 12-15 g,
- peas – 10-20 g,
- beans – 10-12 g.
Norms when growing with seedlings:
- white cabbage – 0.03-0.05 g,
- tomatoes – 0.04-0.06 g,
- eggplant – 0.04-0.08 g.
Multiplying the allocated area for planting with the seeding rate, we get the required number of seeds. Experienced gardeners are advised to add to the estimated weight of 15%.
In any case, it is better to buy a little more to compensate for possible setbacks, but you should not stock up for the next seasons. Seeds need to be stored in certain conditions, which are not always possible to create at home. In addition, with time, germination decreases, so it is better to plant fresh ones, and not those with an expiration date.
However, there are situations when the reserves for the next year are justified. This applies to rare plants that rarely appear on the sale. Or when specific seeds from a proven producer showed excellent results. It is important to consider the fact that the expiration date is for sealed packaging. If open, then the seeds will become unusable sooner.
If you plan everything correctly, then you don’t have to attach it to friends or throw away the grown seedlings. Or, conversely, hastily plant new batches of seeds, violating all planting dates. It is enough to devote a little time to the calculations, and buying seeds from a chaotic event will turn into a rational and rational process.
