Hmmm, no dirt in the boxes as they are a modified skippy type filter. I may try misting a weak solution and see how it goes. Digging up the limestone gravel they are planted in is a odious task, I've had to do it 2 or 3 times when I started this pond. The pond is inside but it is open (through mosquito net high above) to the roof and does get some rain. I hope we are finally heading into a real dry season, I'm tired of the mosquitoes and the rain, it's supposed to be dry now and by May I should be hoping for rain. I am just getting my strength back from dengue fever that I came down with on the 30th of Dec. We had so much rain in the fall that the mosquitoes never went away. I've had the place sprayed several times but almost always it has rained right afterwards.
