Too much water/Too little water
Water is essential for plants. But sometimes too much or too little water can kill the plants.
When is it too much water
It is natural to show your love for plants by watering them too frequently. If this is what you are doing, You gotta stop. When we water the plants, the nutrients in the soil dissolve in the water and plants take up with solution. If you water too much, you are leaching away the nutrients in the soil/potting mixture and all you are left with is soil that is very poor. Also, watering the plants too much leaves the soil with less oxygen causing the roots to choke and suffocate.
How much to water the plants?
Water the plants just enough to see the water coming out of the drainage hole in the bottom of the container. This assumes you have made a drainage hole in the bottom or the container you purchased came with a pre-drilled hole. If there is no drainage hole and you are over watering.. you are in whole lot of trouble. Please ensure there is at least one drainage hole in the bottom of the container.
So to recap, start watering the plants and stop when you see the water coming out of the drainage hole.
Symptoms of too much watering
- Stunted growth
- Yellowing of leaves
- Root rot (happens if the water doesn’t drain).
- Too much algae formation on the soil
- Soil always soggy wet.
Too less water
There are multiple reasons why plants don’t get enough water.
- You don’t water them.
There is no excuse to not watering the plants. If you are too busy to water your plants, be smart and setup an irrigation system that is automated. There are very easy to operate timers available that will play your role for the plants. Seriously! Spend some time watering the plants, you will really enjoy it.
- You water them only on the top.
I have seen this happen with several people. They water the top for like couple of seconds and then they move to another plant. Trouble! Remember the rule. Water should drain from the bottom.
And don’t water the plants using a fine sprayer. It is too fine and it will not wet the soil thoroughly.
- Potting medium is so coarse.
Some potting media are very coarse and they are meant to be like that. For crops like orchids, cacti and succulents etc, the potting soil is so different and they are designed to not hold water. Using such a mix for growing vegetables will result in containers that remain dry all the time. Do not make that mistake. Choose the right potting mix for the crop.
- False drainage.
This is a special case and often found in containers with soil that get very hard and compact over time. They become so compact that they create a space between the inner surface of the container and the soil itself. With a container like that,whenever you water the plants, the water will come right through the sides straight to the bottom without even wetting any part of the soil. So ensure the whole medium gets wet and the water drains.
Frequency of watering
Daily watering is essential but it also depends on where you live. I cannot give you a frequency of watering because you know it better than I do. Yes you really do. To know whether to water or not, stick your finger in the soil about couple of inches deep and if you feel the soil is wet, then you don’t need to water that day. Some places are very hot and there is a need to water the plants may be twice a day.
- Water the root zone
- Water only when needed but do it thoroughly
- Water in the mornings
- Mulch your soil surface to avoid evaporation
That’s all there is to it. Hope you learnt about watering plants.
