Onion seeds are considered to be very healthy. They are the commonest spice used in Indian cuisine. The yellow or black seeds are very rich in dietary substance. The seeds contain proteins, amino acids and a variety of other important minerals. Black onion seed is also known for its medicinal importance.
But while they are useful in many ways, onion seeds can be harmful too. Blackening of your cooking pans with them, can destroy your nonstick cookware and reduce the lifespan of your stainless steel pan. The onion seeds while heating up can destroy your gas burners and stoves. Hence it is better to grow onions in early spring when the weather is just beginning to get warmer.
Growth of onions and garlic in spring is fast due to the availability of nutrients. During the growing season, the hormone of both the plant and the seed is high. This helps quick growth of both plants. Here are some tips that can be followed to ensure quick germination rates of the new seedlings.
Black seedlings need more warmth. This is because as compared to the red or yellow seedlings, black seeds have fewer enzymes. Heat makes the seeds less resistant to fungal attack. So, it is better to place the black seeds in a warm place like an open field.
During the growing season the soil should be moist. Moisture is required for survival of the new seedlings. So, in the early spring when the soil is yet to produce any crops, place the onion seeds in a shallow dish of water. Do not use the pots for keeping the bulbs since heat will kill the new bulbs.
There are many factors that affect the germination of the black seeds. One is the variety of onion used for growing. The more the onion varieties the greater is the chance of success. The second factor is the correct use of soil. The acidic soil is harmful for onion seedlings.
Good soil is the best fertilizer for the onion plants. Make sure that you use a good compost containing potting soil. Most composts contain a lot of moisture, so that they are suitable for growing onions. Potting soil also keeps the soil cool.
The growing of onion seeds via winter sowing via greenhouse grows well when the bulbs are placed on a surface such as a pot. Do not use metal pots for storing bulbs. They may break or bend easily. Also, make sure that the pots are placed in shady regions during the winter season.
There are many gardeners who prefer to grow onion seeds indoors. This has many advantages. The gardeners need not worry about the cold weather, as the bulbs are kept warm and protected. They also have the freedom to move the pots around the garden whenever they feel that the soil needs some changing. Many gardeners also find it easy to transplant the bulbs into the garden when the ground is frozen.
However, there are some disadvantages too. The biggest disadvantage is the inability to move the garden to a new location during the winter. If one plans to sell the produce in the market, the timing of sowing the onion seeds has to be just right. The best time to grow the onion is during late fall or early spring. When the weather is at its coldest, the plants can be transferred inside the house before it starts raining.
Another important factor is the environment where the bulbs are planted. Different climates have different requirements for growing onions. Therefore, it is best to do a little bit of research on the local conditions in your area so as to know what is the best way to grow them in those regions. Do not try to transplant the bulbs into an area which is not very suitable. For example, if you live in a place where there is no shade, then the best way to grow them would be to plant them in the shade.
One of the best ways to grow them is by taking the rhizome and root of the onion leaf and grinding it completely. This can be done either manually or using a hand-operated grinder. Then, mix the powder with some water so as to make a thick paste. This can be applied to the surface of the ground where the bulbs are going to be grown and this mixture will act as the support for the plant during its growth.
It is not recommended to directly plant the onion seedlings into the ground. Instead, it is better to give them time to grow sideways so that they can receive all the sun and water that they need. When you are going to replant them, you should make sure that you leave about one inch of space between each group of bulbs. In addition, if you are going to use the potted varieties, then make sure that you only plant the onion seeds and not the root bulbs.
