can anyone tell me if this is mold or the begining of rooting. In soil rooting the first stages sort of look like this. this is my first time with mangroves. can anybody help please ?
Also, how long have they been in the water? I have mine in the sand, fully submerged, and roots began to appear after about 2 weeks. I know because I had to transplant a couple. Was surprised to see roots so quickly to be honest. The tops had the little green spikes (beginning of the leaves I assume) but have barely grown, again at least underwater. The roots have come out much quicker than any growth on the tops.
I was trying to figure out the same thing a while back! I rinsed them in tap water and wiped the white stuff off. After like a week or two, one of the five has two little roots! The tops of mine were more of a brown than green when I got them so I thought they were just dead.
Sorry to hijack but, are mangroves safe to grow in a display? I've got about an inch or so of sandbed. Will the roots destroy live rock or the silicone seems?
