Do my plants get too many nutrients?
Plants showing yellowing leaves, browns edges or plants that have seriously weakened? In cases like these most people suspect a shortage of nutrients, but sometimes the exact opposite is true and plants get too many nutrients! How can you possibly recognize this? And how do you solve that problem? Read on and you'll find the answers.
Should a plant fail to perform, we tend to give it extra nutrients. Yet, that is not always the best solution. It's far better to find out early signs of weakness: for instance, discoloured leaves may indicate insufficient nutrients but also an excess of them! Here is our overview: now you can check whether a plant gets too nutrients.
How do I know whether my plant gets too much nitrogen (N)?
Nitrogen is an important nutrient for all plants since they need it in order to create chlorophyll (literally 'leaf green') and proteins. Whenever a plant receives an overdose of nitrogen, it tends to grow quite quickly, or rather: too quickly. It will develop floppy stems and its leaves will show dark-green. Eventually a nitrogen overdose will induce the plant to drop, simply because its stems have become too weak and cannot carry the plant's weight. Furthermore, plants like these are prone to diseases (and night frost).
Too much phospor (P)?
Phosphorus is especially important for plants developing roots and fruits. The one advantage of Phosphorus is that you simply cannot give too much of it, as any excess will remain in the soil. However, a Phosphorus overdose may cause a plant to absorb less trace-minerals from the soil, such as iron and zinc.
What about too much potassium? (K)?
Potassium is an important nutrient: in all plants it encourages firmness, photosynthesis and intake of water. A correct amount of potassium helps to develop beautiful fruits and abundant harvest. Potassium excesses also result in fine harvests, but all fruits will contain too much water. For instance, tomatoes on a plant that was given too much potassium will be watery and less tasty. Compact growth is a sure sign of an excess of potassium.
Weakness caused by disease
Weak plants may suffer from an excess or lack of nutrients, but also from pests or diseases. Check your plants very carefully on creepy crawlies or insects; in order to do so raise your plants from their pots to check their root-systems. Never ever give your plants more nutrients when they are diseased! Certain insects love to feed on these extra nutrients and will therefore spread even faster. So do check scrupulously.
Giving too much nutrients to your plants is called overfertilization, to be recognized by dry or withered leaves: these leaves were burned: the large amount of salts present in nutrients have caused the soil to extract water from your plants.
Caution! Some nutrients cannot be given simultaneously! For instance: do not apply lime together with organic nutrient ATA NRG Growth-C. These two substances only destroy each other. On the other hand, ATA NRG Growth-c and Bloom-C, Flavor, Kilomixen Worm Delight form a particular favourable combination. So carefully read the manuals on the packaging of all nutrientsbefore applying them.
