Hi, my tamarillo has stopped growing. The leaves have all turned a deep brown and looks like it's rotting. What have I done? It's grown in a pot in my tunnel house.

Hi Tali 

Is that tamatillo or tamarillo? It could have been over watered, or it could have cooked in the tunnel house if there is insufficient ventilation. This applies to both tamarillo and tamatillo. Feed with Tui Organic Seaweed Plant Tonic at a rate or 30ml per 9L watering can to try and help it recover. 

Thanks, Tui Team.
