They dont like the fluctuation of winter temps inside
.Many homes get cold at night.Thermostat here keeps night temp at 64 but lack of tropical humidity means I water but not too often.
They like a bright room.Mine are in a south facing window.
This is from the year I couldnt hold back taking cuttings and then taking cuttings in Dec and Feb.I had 300 plants.
I used seed starter trays,I dont recoment it.The cells are too small to support a growing root system for 9 months
Coleus inside still need pinching back,its like the gardening never gets a rest.
This was December 2010 I couldnt stop.
I had to put a table in the jacusie for the annex.By May I was so sick of dealing with them I vowed to stop taking cuttings,now DD cuts a few and raises them in her office upstairs.
