>>657046Willow is amazing like that.
>>657044See pic. These red lines are the proper places to cut and place into wet sand or willow water. If you still have access to the tree, I suggest getting new cuttings.
>15-20°CYes, try at least 22C.
>distilled waterNo. Rainwater, well water, or river/stream water, but not distilled water or tap water. Tap water can have all sorts of crap in it that plants hate especially if it is city municple water. Hard water usually isn't a problem but salinity is. If you are using a water softener for your tap water that can be a big problem.
>32cThat should work too.
