Have you ever wondered why weeds never get sick? Yes, because nobody needs them. And all that is needed and good is given with difficulty. Such a simple worldly philosophy. This is a word about how capricious our favorite vegetables, in particular cucumbers. Just have time to rack your brains when it is better to plant them in what soil than to feed, why the ovary is crumbling, why the leaves of the cucumber turn yellow at the edges and so on and so forth. Here is the last and talk in this article.
The leaves of the cucumber turn yellow at the edges. What is this signal?
Changing the color of the leaves can speak of several problems at once. First of all, this happens with a lack of trace elements. If yellowing starts from the edges of the leaf, the plant lacks potassium. For gardeners, this is called a regional burn. The leaves can take a domed shape, and the fruit - pear-shaped. Gradually, yellowness flows over the veins of the leaf plate to the center and leads to drying. If the streaks turn yellow immediately, then a lack of magnesium must be assumed. Each grower has his own conditions, and he himself knows better what kind of soil he has, whether there was fertilizing and when.
Depending on these points, he must feed his beds. It is important not to overfeed: this also often leaves the leaves of the cucumber yellow at the edges, or even completely. The fertilizer application rate depends, as already mentioned, on the initial soil composition on the site. Potassium nitrate is recommended - it is a well-proven
nitrogen-potassium fertilizer. And do not forget about watering, with a lack of which the leaves of cucumbers turn yellow. What if the plant became limp and showed the first signs of yellowing? It is good to pour the settled water so that the moisture reaches the roots. Otherwise, the bush begins to save and redistribute moisture from the leaves to the roots.
Pests and fungal diseases may be the fault
The leaves of the cucumbers on the edges turn yellow and crumble, curl up and dry up when invaded by pests and diseases carried by them. The main enemies of culture (and not only this one) are aphids, whiteflies, sprouts and spider mites. Aphids, which literally sucks juices out of them, destroy the plants more strongly than others. Pests can also carry diseases, for example, spores of anthracnose and ascochitosis. When the first signs appear, urgently need to spray the cucumbers with a 1% Bordeaux mixture or phytosporin. Against pests, you will also have to process the plantings, trying to get the lower parts of the foliage, because it is there that they settle in colonies. Olive and brown spotting are also tolerable diseases, and not a reaction to adverse conditions, as it might seem, although they often begin traditionally - the leaves of the cucumber turn yellow at the edges.
How to save cucumbers with folk remedies
If the grower has his own small garden garden, he wants to grow clean produce on it using a minimum of chemical fertilizers and pesticides. If the crop has not yet been ruined, you can try to save it on your own. For example, take care in advance of saturating the soil with minerals. In the fall, collecting the last crop, you do not have to rush to throw dry tops of tomatoes and potatoes. You can burn it, and scatter the ash around the site - here you have both nitrogen and potassium. From pests, you can practice spraying tobacco and laundry soap with water infusion. If the leaves of the cucumber turn yellow at the edges and threaten to dry, you need to pour them with a solution of pure wood ash. And a couple of simple tips. Cucumbers do not like underfilling, but also can not stand the overflow. The norm can be calculated by taking a lump of earth from a depth of 10 cm and stretching it in your hand: the ground should not be wet, but moderately moist. Also, cucumbers do not like direct sunlight - because of it, they become limp on hot days and literally get a burn. We need to find a way to shade the landing sometimes. Have a good harvest!
