The wooden ash is much more valuable in the garden than it might seem. Especially tomatoes grow stronger, healthier and produce more than usual. Just know how and when to use it.
At a time when more and more gardeners turn to natural ways of fertilization and soil regeneration, the wooden ash returns to the scene as a simple yet very effective fertilizer. It is a material that you often have for free. It is enough to rush with its disposal after winter heating or after a summer campfire. By adding ashes to the roots of tomatoes, you can achieve richer crops, stronger fruits and plants that better resist disease. Why is this and how to use the ashes properly?
Watch a video how to properly bother tomatoes and achieve more crops:
Wooden ash as a natural superhnojiva
Wood ashes contains several key elements that tomatoes need in bulk. Above all, it is calcium and potassium. Calcium helps plants to create a solid cellular structure that has thicker stems and branches and also supports the right germination of flowers. Lack of calcium is a common cause of so -called rot of the flower end, ie common diseases of tomatoes. At the same time, almost 20 % of the volume of wood ash is just calcium.
Potassium is essential for water retention in plants, and because the tomato is made of 90-95 % water, its presence is crucial for the size and juiciness of the fruits. This element also helps tomatoes more efficiently to photosynthetize, ie to turn sunlight into energy needed for the growth and creation of flowers. The ashes also contain magnesium, phosphorus and other trace elements that generally increase plant vitality.
The best time to add ash is when planting. About 1.5 cups of ash can be mixed into each hole and then sprinkled with the surroundings. If you have crushed egg shells on hand, add them! This will support even more calcium intake. After planting tomatoes, fill the ash with a mulch, such as straw or chopped grass. The ashes will not be repaired and will act directly at the roots. During the season, about half a cup of ash can be attached around the plants as a surface fertilization.
What do not underestimate and how not to overlook
Although the wood ash is a natural source of nutrients, it needs to be treated in moderation. Excess of the ash can increase soil pH, which could rather harm the plants. Tomatoes prefer neutral to slightly acidic soil, ideally with a pH between 6 and 6.5. Therefore, it is recommended not to overdo it with doses and possibly buy a home test for pH soil, which is commonly available in horticulture.
Wood ash does not replace complete care of plants, but in conjunction with compost, mulch and regular watering becomes a strong helper to increase the harvest and health of tomatoes. Moreover, when used with reason for soil needs, the difference can be really visible. And if you are gardening because of your own health, remember that tomatoes are a valuable source of antioxidants and thus a great helper in fighting various diseases!
