Importance of root system in keeping plants alive
Owner of Caloundra Garden and Pet Supplies A QUESTION I often get asked is “Why do my plants grow for a bit and then stop growing or die?”
The reason plants are able to grow is because of the root system in the soil.
The roots get their nutrients and moisture from the soil and transfer it to the stems and leaves.
This bit is very important – in general the root system below the ground should be as big as the plant above the ground.
The main reason why a plant’s roots don’t grow is it is getting all it needs right where it is.
The water and nutrients are delivered right at the top of the soil and it does not need to go anywhere to get what it requires.
So to make the root system grow, you need to make it search for its food and water.
Water deeply and, depending on your plant’s position, you should not water it more than once a week.
Scratch the top of the soil down a few centimetres and if there is still moisture there, do not water it.
I had a tomato plant in a pot I watered less than once a month if it did not rain.
When it was finished, the pot was full with roots.
Food for your plants should be deep in the soil as well, so when planting, add a slow-release fertiliser and it will continue to feed your plants for months.
THRIVING: This tomato plant is thriving in a pot.
