We understand. As a newly minted bonsai enthusiast, you probably
have dozens of questions about caring for your bonsai. Don't worry;
you're going to be fine. After all, your friends at The Bonsai
Outlet are here to help.
Today, we're here to talk about watering
basics. This is one of
our favorite topics because it allows us to confront one of the
most common bonsai myths head-on.
You've probably heard some version of this by now: "I've
heard that bonsai are fragile. I don't think I could keep one alive." Let's
just hope these types are content with their pet rocks.
But this misconception is out there, and unfortunately, it's not
helping bonsai's popularity. While it's true that some plants may
go to that "great garden in the sky" prematurely, it
is our opinion that dubious watering practices usually have something
to do with their early demise ... and that effective watering
can prolong the health and vitality of your bonsai.
All of this brings us to the subject at hand: Watering Bonsai . Over the
years, we've heard our share of questions on the topic. How often
should I water? How much? When is the best time? We thought we
go through some watering basics so you can get the information
you need to take the guesswork out of watering and start down the
road to having a healthy, happy bonsai.
After all, isn't that what it's all about?
How often should I water my bonsai?
Ah, therein lies the question, but unfortunately, only you know
the answer. Why? Because you are the only person that can monitor
your tree every day in order to determine the most effective
watering schedule.
Sorry, we can't give you a more specific answer, but here are
some pointers to consider. The frequency of watering will depend
on plant location, type, and material, type of soil, the depth
of your bonsai pot, lighting, and more.
How do I check my bonsai to see if it needs watering?
This may be easier than you think. Push the top dressing aside
and insert your finger approximately ½ inch into the soil.
Is the soil cool and moist or warm and dry?
If the soil is more on the warm and dry side, chances are good
you're ready to water.
How should I water my bonsai?
There are actually two watering methods: Overhead watering (best
for outdoor bonsai) and immersion watering.
The overhead watering method
Let's start with the overhead watering method. You'll need a hose
or a watering can, but be careful: Make sure you deliver a fine
spray of water; otherwise a strong blast of water can dislodge
soil or damage your bonsai. We recommend using a watering
can rosette for just the right spray.
To water, simply pour water over the plant and allow it to flow
into the soil. If water puddles on the surface of the soil, let
it drain into the soil and water again.
Keeping going until water begins to run out of the drainage holes
in the bottom of the pot. Keep watering for a minute or two more
to make sure the entire soil mass is soaked.
The immersion method
Probably the most popular and the most-effective method for indoor
bonsai. Fill a bucket or sink full of water to the point where
the water should go to about one inch up the trunk.
As you submerge your tree, you will see bubbling from the root
ball. Pay close attention: The vigorousness of this bubbling will
indicate just how much water your tree needs. As you become more
in tune to your bonsai, you will come to recognize various levels
of bubbling.
For example, if your tree produces bubbles like boiling water,
chances are that you're not watering enough. If it bubbles slowly,
you may not be watering enough. Watering your bonsai – much
like life – is finding the right balance.
But back to the watering. Keep your bonsai immersed until bubbles
stop rising to the surface. When they're done, you're done - no
more bubbles means that the root mass is thoroughly soaked. Slowly
remove the tree and allow it to drain.
Tip from The Bonsai Outlet: If too much soil or top dressing keeps
getting washed away, keep your water levels below the rim of your
bonsai pot. The water will still soak up through the drainage holes
of the pot and provide adequate water for your plant.
And remember, misting is not an acceptable method of watering.
It may refresh and clean foliage, but it doesn't provide enough
water for your bonsai.
Final words of wisdom
The goal of bonsai watering is to provide even and moderate moisture
for the entire root and soil mass. Each variety of bonsai requires
a varying amount of moisture, so you need to monitor your tree
closely to see what it needs.
The good news is that after the first couple of weeks, you will
determine a schedule or pattern. Stay alert to any changes and
adjust your schedule accordingly, and you'll be off to a good start.
