Carnivorous Plants/Water in tray


Hi Jeff,

I heard that there are no dumb questions ;-) So IŽll ask...

Does it make any difference to the soil of a potted plant if the pot is constantly in a tray of water (that does not dries out) that is only 1 cm deep or 3 cm deep?

If the pot constantly sits in a deeper amount of water, will the water reach out more of the soil, or the deepness does not matter?

I am asking, because I was wondering if I can "control" the wetness of the soil by putting plants in different trays. I would go for smaller (in diameter) and lower trays with Flytraps and Pinguicula and bigger ones for Sundews/Sarracenia. Still, all have in common they would be always full of water, since IŽll use the drip system.

Thanks a tons!



Hi JP,

If I understand your question correctly, the water depth does make a difference.  We vary the water depth all the time for plants based on the type of plants.  A good example is in one of our greenhouses we keep just a little water in trays of Mexican butterworts.  They don't like to be waterlogged.  Sundews, however, we fill the trays.  They love being wet (most of them anyway; always exceptions), and many are found in nature right at the water level.  For hardy varieties D. intermedia is a good example of this.

So, having various depths of trays is a great idea.  Also, if your drippers come on frequently enough, you might not need water trays at all.  Darlingtonia loves being watered this way.

Good Growing!
