Butterworts (Pinguicula)

Tropical Butterworts

Light

Tropical Pinguicula Butterworts need strong light but must be protected from scorching sunlight. If grown indoors they need a very sunny window and/or to be 2 to 4 inches directly under a fluorescent light that is on for 12 to 18 hours a day.


Water

Do not water Butterworts with tap water, purified water, drinking water, or mineral water. They must have Reverse Osmosis or Distilled water only. You can buy Reverse Osmosis or Distilled water at your local water store or grocery store. Just check the fine print to make sure it doesn’t have anything else added to it. Put your Butterwort’s pot in a bowl or saucer. Fill up the bowl or saucer with Reverse Osmosis or Distilled water to about 2/5ths way up the pot. When the water evaporates to near the bottom of the container refill it back to about half way up the pot again. Never let the Butterwort’s soil dry out.


Feeding

Butterworts eat small insects like ants. They can be fed by sprinkling small insects on their sticky leaves. If you grow your Butterwort outside you do not need to feed it all. It will catch bugs on its own. Don’t use fertilizers for your Butterwort.


Leaf/Trap Growth

If your Butterwort is shedding its lower leaves don’t worry this is normal, as long as there is also fresh new healthy leaves emerging.


Potting

To pot up your Butterwort first put your long fibered sphagnum moss in a bowl with Reverse Osmosis or Distilled water. Make sure to loosen the fibers and mix it around in the bowl to help it hydrate. Then use this as your potting soil for your Butterwort. You don’t need to firmly pack it into your pot. It is better if it is loose and airy.


Dormancy

Tropical Butterworts do not need to go dormant. But they should be protected from frost. They may slow down in cooler temperatures. This should not hurt them though and they should start growing more quickly again once they experience warmer temperatures.

Dormancy

Every Winter Temperate Butterworts need to go dormant. If you grow your Butterworts indoors or you get more than a light frost where you live you will need to put it in a cool place in your house for the Winter. Do not put it back outside until the last frost is over. When Butterworts go dormant some of their leaves may dry up and turn black and they grow small leaves or no leaves for all of Winter. If you see this happen to your Butterwort in November to December don’t throw your Butterwort away. They are supposed to die down every Winter. They are annuals. They will regrow right back every Spring and maybe make a flower for you too.
