I started eucalyptus neglecta 'Big O', eucalyptus elliptica 'Grace', and eucalyptus camphors 'Lucky Country' from 4" containers about a year ago. My goal was to grow them in pots on the patio of my Tampa home.
Originally the soil in the pots dried out quickly in the Florida heat and needed to be watered daily.
Larger pots with water reserves helped immensely and now they stay well-watered throughout the hot Florida days!
Aside from some occasional black mites on 'LC', they're all real healthy and pest free.
They smell absolutely amazing and the cuttings have been helpful in keeping my home smelling nice. A bonus is that my bird cages smell nice too and the birds love to chew on the leaves and bark.
