How to Water Herbaceous Perennial Plants

How to water

Feel the soil - the top layer (about 1 inch) should be dry before giving more water. If the soil is still wet, you risk giving the plant too much water and it can rot. There are several ways to water your plant. Choose a way that suits you the best.

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

Water over the soil

  1. Pour water over the soil, using, for example, a watering can or put the plant directly under a tap

  2. Continue adding water to the pot until it starts to run out from the drainage holes

  3. 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

  4. If you watered under a tap make sure that water has stopped running out from the bottom before putting it back

Make sure your pot has drainage holes - without these your plant risks rotting in the excess water that can’t exit.

Bottom watering

  1. Fill the plant tray with water

  2. Make sure the soil is in contact with the water on the tray

  3. Wait for about 10 minutes

  4. Feel the soil to see if it absorbed enough water —> if the soil is moist throughout, remove any excess water from the tray

  5. If it’s still dry —> add more water to the tray

  6. 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

  1. Fill a bucket or any other vessel with lukewarm water

  2. 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

  3. The water will now start to bubble - wait until it stopped

  4. Lift the pot up and let the excess drain off

  5. Put your plant back in the cachepot or on the tray

  6. After 1 hour, check that your plant isn’t standing in water, if it is it might get overwatered and rot

It’s often easier to kill a plant with overwatering than with underwatering, and it’s usually much easier to save an underwatered plant than the opposite.

よくある質問

How do I know when to water my herbaceous perennial plant?

You should water your herbaceous perennial plant when the top inch of its soil feels dry to the touch. If the soil is still wet, it's best to wait a bit longer.

What are common ways to water my plant?

There are several effective ways to water your plant, including pouring water over the soil, using a bottom watering method where the plant absorbs water from a tray, or giving it a water bath.

Why are drainage holes important in a plant pot?

Drainage holes are essential for your plant's health as they allow excess water to escape, preventing the plant from sitting in water and developing root rot.

Should I only use bottom watering for my plant?

While bottom watering is effective, it's important to also water over the soil occasionally. This helps to flush out any accumulated salts and minerals from the soil.

What are the risks of overwatering my plant?

Overwatering can cause your plant to rot, and it is generally much more difficult to save an overwatered plant than one that has been underwatered.

How to Water Herbaceous Perennial Plants Over the Soil

  1. Check the soil, making sure the top inch is dry before adding water.

  2. Pour water over the soil until it flows out of the drainage holes.

  3. If you use a drip tray, always empty any collected water afterwards.

  4. If you watered under a tap, wait for all excess water to drain before returning the plant.
