Watering weed plants… it seems easy and in fact, it is, but watering often goes wrong. Novice growers give too much rather than too little water, which causes the roots to suffocate and stagnate growth. Fortunately, customized watering is not difficult, as long as you know the right tricks.
Apart from light, successful weed growing is mainly about finding the right balance. A breeze can be good, but too much wind can dry out leaves, enough fertilizer is essential but too much can cause leaves to wither. This is also the case with water. weed plants cannot live without it, but when the soil is too wet, the roots no longer get oxygen, causing them to suffocate.
Where watering weed goes wrong
Growing weed plants is not difficult, but it requires patience. The temptation to give more water is great when your weed plant is just as small at night as when you looked in the morning. But you shouldn’t do that because weed plants do not particularly like wet feet. Their roots need a lot of oxygen in addition to water and fertilizers. They get this from the water itself, but especially from the air in the earth itself. When the soil is too wet, the roots grow in stagnant water and the roots choke.
The temptation to give more water is large and disastrous with small weed plants and seedlings.
The consequences of too much water are actually consequences of too little oxygen at the roots. What you see in the plant are downward-hanging leaves, and in a more advanced stage, leaves that wither; symptoms that you also see with weed plants in hydro systems with water that contains too little oxygen.
How to judge the amount of water you have given your weed plant
There are quite a few handy tricks to give just enough water. Some growers lift their pots every day to feel the weight of the water balance. Others allow the top layer of the soil to dry to an inch or 2 or 3 between waterings.
However, it is better and easier to look at the position of the leaves. Both a shortage of water and a water surplus can be clearly seen in the leaves. And even when a weed plant is completely content with the amount of moisture in its medium, it shows you that with its leaves.
- Sagging leaves = deficient (too dry)
- Sturdy, downward-curling leaves = surplus (too wet)
- Leaves tilted up = not too dry, not too wet (just right)
With a shortage of water, a weed plant will leave its leaves hanging. The leaves not only hang down, but they also feel weak. Of course, you should not let it get that far, but try to direct the leaves upwards towards the light. That is, after all, the way in which your weed plant indicates that it is doing well in terms of water.
On the other hand, when a weed plant is too wet, you can clearly see it in the leaves. The leaf fingers curl down like claws. Do not confuse it with limp leaves; in the case of a water surplus, the leaves do feel firm. The leaves indication method works for both weed plants in soil and weed plants that are grown in hydro systems.
How to ensure proper nutrients are in the water
When preparing nutrient water, it is important that you follow the correct sequence and give the water the chance to get up to temperature. When the water is much colder than the ambient temperature, the plant receives a temperature shock. Conversely, too hot water can cause the roots to get too little oxygen. The temperature of the water also influences the pH value.
It is, therefore, best to first allow the water to warm up in your grow room overnight. Then add all the nutrients to the correct EC value (if necessary, with an organic culture you cannot measure the EC value and you do not always have to monitor the pH value) and only then do you apply it the correct pH value (if necessary).
How to check the soil for watering timing
When the top layer of soil has dried up a lot, it can happen that the soil no longer absorbs water easily. You notice this quickly enough, the water runs out of the pot almost immediately at the bottom. When your pots are each on a separate dish, it doesn’t really matter. The earth will then absorb the water from the bottom.
However, if your plants stand together in one drip tray, this is a problem because the water runs to the lowest point and the plants that are there, then absorb all the water from the other plants. The result is that some plants get almost no water and others are too wet. You also do not always realize this immediately, which can lead to serious problems with the plants.
When the soil is very dry, the water cannot absorb properly.
What you could do to prevent this is to either provide a separate dish for each pot, water in slow stages, or use a run-off. Watering in slow stages simply means that you first carefully give each plant a small amount of water, wait an hour and then give it a little more water, wait another hour and only then give the rest of the water. In this way, the soil gets the chance to absorb the water.
A flux lowers the surface tension of the water so that the earth can absorb it well again. Yucca is such a drawer, it is a natural product that is made from the juice of the Yucca (also called palm lily). You can also add a drop of detergent to a bucket of water, but make sure that you do not use more than one drop on a bucket and that you do not have to use this more often, detergent is of course not good for weed plants.
