Why does dill twist and how can it be processed?
Novice gardeners often encounter such an unpleasant phenomenon as dill twisting. It would seem that all the conditions are met, the plant sprouts on time, develops well, but at some point it starts to spin - the crop can be considered lost. To save culture from this phenomenon, it is necessary to understand the causes of what happened.
What does it look like?
It is believed that dill is a rather unpretentious plant, so some summer residents do not really care about caring for this crop. In this regard, the first signs of an unhealthy state of dill may be overlooked.
A normal healthy plant is characterized by a rich green color, splendor, it is pleasantly fragrant.
If the dill looks sick and weakened, its leaves wither and curl, the plant turns yellow, dries, then this indicates improper care. If timely action is not taken, the harvest may be lost. However, before embarking on the salvation of culture, it is necessary to identify the cause of the phenomenon.
The reasons
We will find out the possible causes of dill twisting.
- Drought. Despite the love of the sun, dill is very vulnerable to excessive heat and a long absence of moisture.
- Bad soil. The most unfortunate soil options are acidic and clay soils. On acidic soil, dill is unlikely to grow at all, the solid structure of clay soil will also not allow seedlings to break through. If the strongest specimens hatch, then from weakness they will begin to twist and die.
- Verticillium wilt. This is a fungal disease that penetrates into the microcracks of the root system from the soil. It prevents the plant from getting the necessary moisture.
- Dense landing. The most common reason. A plant can spend energy on itself only if it is at a sufficient distance from its neighbor, otherwise the seedlings will crowd each other out. In the case of dense sowing, the lower leaves do not have enough lighting, the top of the head twists and dries.
- Aphid. Looking closely at the twisted leaves, aphids are easy to spot with the naked eye. Colonies of transparent greenish insects settle in the succulent leaves, usually the top sheets.
What to do?
To correct the situation, it is necessary to eliminate the cause of twisting.
- If the cause of the drying of the dill was drought, then provide it with abundant regular watering. Pour water at the base. It is better to water in the evening. It is allowed to cover with agrofibre.
- If the plant is affected by verticillium, then the damaged specimen should be eliminated along with the root. It is recommended to place a container with healthy soil on the excavated area so as to avoid contact between new and old soil.
- To combat aphids, you can treat the culture with any chemical agent, but this method is only suitable for plants planted with seeds in open ground. In addition, this is an extreme option, since the greens will subsequently be used for food - you need to choose the least toxic solutions. If planting was carried out by the seedling method, then it is better to process the greens with tobacco dust or shag.
- Only preventive measures will help protect the plant from bad soil. Before planting, organic fertilizers, manure, sawdust, straw are applied in advance.If the dill has already begun to curl, then it is allowed to transplant it to a new place prepared in advance and flavored with special mixtures. It is recommended to supply the soil with ash, dolomite flour, lime already in the fall.
- Too thick seedlings can be thinned out, leaving a distance of 2 cm between each. As the culture develops, the procedure is repeated, each time the gap increases.
What are the means to get rid of it?
If aphids became the cause of dill twisting, then it is necessary to follow the rules for treating the plant from insects. The fact is that an excess amount of chemistry, which is sold in specialized stores specifically for protection against aphids, can adversely affect the condition of the dill. Not only will it get a specific taste, but it can also absorb harmful chemicals that can enter the human body.
Therefore, in general, summer residents prefer to use mixtures prepared according to folk recipes from harmless ingredients to combat aphids. One of the most common recipes is an infusion of tomato or potato tops:
- 1.5-2 kg of potato or tomato tops cut into small pieces;
- fill with a bucket of water and insist for 3 hours;
- instead of insisting, the mixture can be boiled for half an hour;
- rub 30 g of laundry soap, liquid soap can also be used;
- add it to the infusion;
- we spray in the morning and evening.
The poison solanine, which is contained in potato tops, is able to destroy aphids. In general, the insect has a weak cover, which allows even weakly poisonous agents to pass through.
Another effective recipe for an aphid protection composition is prepared on the basis of tobacco:
- grind 100 g of tobacco leaves;
- fill with water and leave to infuse for a day;
- filter and add soap;
- it is allowed to use hot pepper, pyrethrum.
In this case, nicotine will be a detrimental substance for aphids. Whatever means the summer resident chooses, after harvesting, it is necessary to thoroughly rinse the greens.
In general, the aphid is not poisonous and not dangerous to humans, but few people will like the prospect of using the plant along with the insect, and it is almost impossible to manually clean the greens from aphids.
Recommendations
To avoid leaf curl, you need to take into account all possible causes of this phenomenon in advance and prepare the conditions under which dill will grow healthy, tasty and healthy. To do this, you need to familiarize yourself with the recommendations of experienced gardeners.
- You can not grow dill on the same ridge where it grew a year ago. It is better to alternate it with legumes and nightshade, gourds. This measure will protect the greens from infection.
- Verticillosis often affects strawberries and beets, therefore, after these crops, it is strictly forbidden to plant dill in the same area for at least 5 years.
- To avoid the invasion of aphids, it is worth refusing to plant dill next to begonia, beans, mallow, linden, bird cherry, viburnum.
- Plants that repel aphids are mint, basil, mustard, fennel. They are recommended to be grown next to dill.
- The most favorable top dressings that protect against verticillium wilt and other infections are potash and phosphorus mineral fertilizers.
- It is better to disinfect the seeds before sowing. To do this, soak the planting material in a solution of potassium permanganate for 20 minutes. The spores of the fungus will die, but the healthy germ will remain.
