Question
Hi cobra guys!
)
I have had my Drosera Capensis now for 6 months and is has started to send out a flower. Last month i have noticed that the end of some leafs are turning black and its getting more and more black ends. They still have dew on them even the ones that are half turning black. My question is of this is normal when starting to flowering or if its something that i need to keep an eye on.
I have it growing indoors under UV lights. I use rainwater with TDS 5-10 ppm and i dont have more the 1/4 of the pot in water. The soil is 1 part peat and 1 part perlite. My location is in Borås, Sweden.
Hi Patrik,
When the ends of the leaves turn brown like this, it's usually a result of rapidly changing humidity. The older leaves or older growth) are most susceptible to rapidly changing humidity, this is especially true as the season changes. Overall, your plant looks very healthy. The color looks good, the leaves look very turgid and the plant has lots of dew.
If you prefer, simply cut off the leaves that are affected. Other than that, your growing conditions are just fine.
For more information about sundew problems, I suggest taking a look at Volume 2 of our Grow Carnivorous Plants DVD series. In this volume we cover tropical sundews and some of the common problems, such as this.
