How to Water a Venus Fly Trap

How to water

Venus Fly Traps love water and do not like to dry out at all. Feel the soil: it should be moist or slightly wet when watering it again. Squeeze a bit of soil between your fingers - if water runs out it’s too wet.

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

Always use mineral-free water when you water your Venus fly trap, such as rainwater or filtered water. Bottled and tap water contains too many minerals and can ‘over-fertilize’ or ‘burn’ your plant.

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

Carnivorous plants love the perfect balance between wet and moist soil. They don’t like to dry out even once and they don’t want to be drowning in water, at least not all of the time.

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

Plants can soak up water more easily when it is roughly the same temperature as the surrounding air.

Ofte stillede spørgsmål

What kind of water should I use for my Venus Fly Trap?

Always use mineral-free water for your Venus Fly Trap, such as rainwater or filtered water, as tap or bottled water contains too many minerals that can harm it.

How can I tell if my Venus Fly Trap needs watering?

Feel the soil to check its moisture; it should be moist or slightly wet. If water runs out when you squeeze the soil, it is too wet and does not need watering yet.

Is bottom watering a good method for Venus Fly Traps?

Yes, bottom watering is effective, but remember to water over the soil occasionally. This helps wash away any accumulated salts and minerals that bottom watering doesn't remove.

Why is mineral-free water important for Venus Fly Traps?

Bottled and tap water contain minerals that can 'over-fertilize' or 'burn' your Venus Fly Trap. Mineral-free water ensures your plant receives hydration without harmful mineral buildup.

How do I water my Venus Fly Trap using a water bath?

Fill a bucket with lukewarm water and lower the entire pot into it, stopping where the plant's stem begins. Wait until the bubbling stops, then lift the pot and let the excess water drain off.

How to Water a Venus Fly Trap

  1. Pour water over the soil, using a watering can or by placing 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, make sure to remove all collected water afterwards to prevent the plant from sitting in water.

  4. If you watered under a tap, ensure that water has stopped running out from the bottom before putting the plant back.
