How to Water Your Petunia (Petunia x hybrida) Plant

How to water

Feel the soil; it should be a bit moist but not wet when watering it again. Squeeze a bit of soil between your fingers, if water seeps out it's still wet.

If the soil is wet - snooze this action, we will remind you again in 2 days.

Water over the soil

Pour water over the soil, using, for example, a watering can or put the plant directly under a tap
Continue adding water to the pot until it starts to run out from the drainage holes
If you have a tray under the pot when watering, make sure you remove all the collected water afterwards - never let your plant sit in water
If you watered under a tap make sure that water has stopped running out from the bottom before putting it back

It might actually be kinda tricky to overwater a Petunia, but it doesn't like to swim either so just make sure that the soil doesn't get too wet.

Bottom watering

Fill the plant tray with water
Make sure the soil is in contact with the water on the tray
Wait for about 10 minutes
Feel the soil to see if it absorbed enough water —> if the soil is moist throughout, remove any excess water from the tray
If it’s still dry —> add more water to the tray
Wait 20 more minutes before removing the excess

Note

Bottom watering will not wash away salts and other minerals from the soil, so make sure to also give water over the soil every now and then.

Water bath

Fill a bucket or any other vessel with lukewarm water
Lower the whole pot down in the water, stop where the stem of the plant starts. Make sure all of the soil is under water
The water will now start to bubble - wait until it stopped
Lift the pot up and let the excess drain off
Put the plant back in the cachepot or on the tray
After 1 hour, check that the plant isn’t standing in water, if it is it might get overwatered and rot

How to Water a Petunia (Petunia x hybrida)

Check the soil moisture by feeling it; it should be slightly moist but not wet.

Choose a watering method: pour water over the soil, use bottom watering, or give it a water bath.

For top watering, pour water over the soil until it runs out the drainage holes, then remove any standing water from the tray immediately.

For bottom watering, fill a plant tray with water, allow the soil to absorb moisture for 10-20 minutes, then empty any remaining water.

For a water bath, submerge the pot in lukewarm water until bubbling stops, then lift and allow all excess water to drain thoroughly.

Ensure your Petunia is not left sitting in water after any method to prevent overwatering and rot.
