The expert said that it is important to consider the anatomy of your plant

A common problem gardeners face is knowing when to water their houseplants.

They are constantly in the loop of not trying to overwater their plants as it can lead to root rot and stunted growth, or underwater their plant as they may not get the nutrients they need.


YouTuber, Tanner The Planter, shared with people a watering method which helps recognise the quantity of water that is needed to give houseplants the nourishment they need.

He said: "I developed this method for watering houseplants that have helped dozens of people across the world. The method I am talking about is kind of like baking."

The amount of water your houseplant needs varies based on leaves, stems and roots

"By looking at certain anatomies of your plants, you can get a pretty good ballpark of when you should be watering them," said the expert.

He said people should examine the denseness of the leaves, the stems and the roots.

Tanner explained: "Each one of these places can have some water storage in there and depending on how much water storage each part has, will determine the amount you are watering."

As well as the structure of the plant, people need to consider the soil the plant is in.

The second step is to measure the dampness of the soil which can be done by using something like a sewing needle or a chopstick.

The gardener compared this part of his method to baking.

"If you have ever baked something like a cake and when the timer goes off, you use a fork or a knife that you insert into the middle of the cake to see if the batter is done," Tanner said.

"If you bring your knife out and there is still wet batter on the cake, you know the cake is not ready to come out of the oven. This is the same principles that we are using to check out plants to see if they need to be watered."

Tanner also said that to lower your probe into the soil, leave it there for a few seconds and take it out. If you notice that some soil is attached to it, then you know you do not need to water your plant as you will run the risk of overwatering.

"Once you see that your probe has nothing on it, that's when you water your plant and give it a thorough soak," the gardening expert said.

He told people to remember before they water their houseplants to check the pot they are in too.

Gardeners have also been told a crucial task they need to complete before entering spring.

The task massively helps roses bloom when the warmer, sunnier weather starts to arrive.
