Fish Aficionado
There's much discussion about how we determine whether or not our fish are healthy and/or thriving, but much less on plants.
Plant growth is obviously slow and, with daily exposure, it's easy to miss just how far my plants actually have grown.
A series of photographs have been an excellent tool in this regard, clearly identifying for me what appears to be growing well and not-so well.

- Growth can be used as an indicator of plant health, but not if that growth is weedy, or the plant becomes thin and 'leggy'. Then there's growth of new leaves and of roots to consider.
- Leaf colour is always a good indicator, but care has to be taking in observing the actual colour of the leaves and knowing what colour they should be. For example, some might start off a nice red shade and become green, or even vice versa.
- 'Pearling' has to be my favourite indicator, simply because those little silver balls of oxygen tell me that the plant is doing what it should and is effectively photosynthesising. (I suppose that, after dark, pearling with CO2, as a by-product of respiration, may also occur, but I'm usually asleep by then. Can anyone confirm whether or not this occurs?)
