Question
Hi guys,
Question: i grow different nepenthes and they are growing very good, i have some plants with enormous leaves
and the plants are getting really big but i don't have any pitchers. All my plants are sitting on a southern windowsill. I water them on a regular basis and mist them also twice a week with rainwater. So why doesn't my plants produce any pitchers? The plants are ventrata, Miranda,ventricosa and sanguinea.
I hope you can help me.

Greetings from belgium.

Hi Geerard,

From your description, your plants are not getting enough sunlight. Ideally they should get several hours of direct sunlight each day.I know you have it in a southern windowsill, but if your winter was very cloudy, you won't have enough sunlight to keep the plants fully happy.  Even for us, our Nepenthes stop producing pitchers in winter because of heavy cloud coverage.

In the best of situations, your Miranda should have reddish leaves.  This is how you know it's getting lots of sunlight.  If the leaves are green without red hues, then the light intensity is too low.  During the summer months, I place my ventrata and Miranda outdoors under a tree where they get dappled sun unitl midday and direct sunlight in the afternoon.  It's only then they produce pitchers.  

For now, you may need to accept your plants being pitcherless until you can increase the light intensity.  Perhaps when the weather is warm enough you can hang your plants outdoors where they can get some direct sunlight.

By the way, you don't need to mist your plants.  The varieties you have acclimate well to lower humidity.  Even with Nepenthes in my home, I don't mist them at all.  Misting is only necessary with ultrahighland plants.  In general, for misting to have any impact on a plant's growth, it needs to be done at least several times a day.  Once daily has no effect whatsoever.

Good growing!
