is there a general rule?
 

I have 5 Differant dens and 3 are a unknown type. I have a sakda blue and a haleahi heartbeat x blue twinkle 'tetra'. Are there any general rules as for care i am new at this and know nothing about winter breaks or any special care?

it realy does depend on the type of den ....

deciduous which drop leaves in fall need different culture from evergreen types and even then you can have a couple that need a winter rest such as agragatum that dont drop the leaves...

then you have the ones that are evergreen IE keep their leaves and you just water and feed pretty much all year ....

hard to realy say there is a general rule the only way you can get a general rule is to determine which type yours are then someone can give a general rule perhaps for that type

i have no idea what the 3 are but how about the 2 that i did list

LOL I dont know them by name I just got my first non noid dens this summer ....hope some one else can help

there are no letter designations other than DEN on both tags
