To soak or not – that is the question
Tend to to onions, it is grown from sets (small bulbs with a diameter from 1 to 3 cm). Even experienced gardeners are wondering whether to soak the onion sets before planting. In fact, the process of soaking serves several purposes: a lot of seedlings, disinfection of pests and the rapid development of the root system.
Fibrous root system of onion is underdeveloped, and if you hold the bulbs in water before planting only half an hour, you can see how thin roots have already started to move out. This does not necessarily add to the water accelerating the growth of the fertilizer is sufficient only to pour the water at room temperature.
What to soak the onions before planting
If desired, you can resort to complex fertilizers for vegetable crops. The fertilizer used at the rate of 1 tablespoon per 10 liters of water. Only half an hour then it will not be. Experts recommend to leave the sets in the solution for 8-10 hours.
The most vicious enemy sowing of onion – onion fly, but she can find justice for soaking and salt. If you hold the onion in a salt solution, it will help to prevent the deposition of larvae of the onion fly, and therefore the mass death of Luke.
To prevent fungal diseases of onion soaked for 10-15 minutes in a solution of copper sulfate (1 tsp per 10 liters of water) or in a weak solution of potassium permanganate. The latter method appears to be simple and affordable, especially since he's proven years of experience grandmothers.
All of the above does not mean that the sets needed to survive in all these solutions. You should choose the most acceptable. And, if you protolith onions for 2 hours in the "cool" solution: 1 kg of salt to half a bucket of water, the sulphate or potassium permanganate is no longer needed. Salt save from onion flies, and disease.
Prepare to bow to the soaking
Before soaking, the sets need to go through and remove delaminated the husks and sort by size. Bulbs that have allowed the greens, are subject to rejection.
In the next step to remove the top neck. This is easier to do with scissors or a knife. The bottom with the beginnings of roots remains intact. The procedure for removing the tops is optional, especially if the onion is planted like a turnip. After cutting the feather appears faster and grow more smooth without creases.
Advice 2: How to save onions from disease
Sakova rot – a common disease of onions. Before planting, treat sets in a weak solution of potassium permanganate. Put him in warm but not hot or rainy weather, so he settled down and soon began to rise. Sometimes the rot begins to occur at strong watering. Try to control the moisture level of the soil. Better proryhlit than irrigating.
Powdery mildew – a fungal infection of the feathers. Usually manifests itself by the appearance of whitish plaque and light spots. Then the color changes to slightly violet, after which the leaves gradually turn yellow and wither. To protect the bow from the death, treat it with a solution of a tablespoon of oxychloride of copper and the same amount of liquid soap per 10 liters of water. As prevention orosite planting composition every 2 weeks.
Stem nematode also causes a lot of trouble to the vacationers. The stems of onions appear whitish worms. A relatively small parasites are able to destroy all the beds, if time does not begin to fight them. Even before the boarding process sets the salt solution – 5 liters water 3 tbsp After 30-40 minutes, not washing proceed to the landings. To get rid of nematodes, and using the complex preparations against pests that are sold in stores. Use them as instructed.
Get rid of onion fly can be a tobacco solution. Pour into 10-liter bucket of 200 grams of tobacco. Insist 3 days. Add a tablespoon of liquid soap and as much black pepper. Strain the solution through several layers of cheesecloth and spray onion spray.
In principle, from most pests help complete the preparations. But they contain chemical ingredients, so if you want to get environmentally friendly onions, use proven traditional methods.
Advice 3: Do I need to water the onions
Do I need to water the onions after planting
Some gardeners believe that after planting, onions need to be watered, and so that the seedlings were in the "swamp" conditions and was practically floating in water. Others believe that watering is unnecessary, or even harmful to the growth and development of vegetables. However, I want to remind you that any plant for normal development of the necessary moisture, the bow is no exception. At the same time this vegetable is in excess of water in the soil can easily rot, so to fill the plants is not necessary.
If you just plant onions and not know whether to water it or not, you have two options: if you before planting the garden shed with water, in this case the irrigation is missing, if the pouring is not carried out, water the seedlings is necessary, and so that no water gets on the bulbs.
Do I need to water the onions in July and August
If Luke has a well developed root system, then the need for irrigation depends solely on the weather. In the month of July often there are droughts, the rains are absent more than seven consecutive days, the temperature reaches over 25 degrees Celsius. Under these conditions, moisture from the soil evaporates and the plants it is not enough, which negatively affects their development, so watering a bow, most often, simply necessary.
If July is not poor rains, then pour the onion unnecessary. As for August, this month rarely skimp on precipitation, and given the fact that the rapid growth of the onion is the end of July, the watering of these plants in the last month of summer you can not carry out.
Remember, in hot dry weather onions need to be watered once every five days, if the rain comes at least once a week, that is, refrain from watering, otherwise you can not avoid Fusarium vegetables.
