Do not be concerned if you see white residue on the leaves of your plant when it is delivered. The white substance on the leaves is fertiliser residue and will not affect the plant at all.  

Many of our plants are fed/watered from above whilst in the glasshouses, so if the weather is particularly hot and sunny, the water can evaporate from leaves quickly, leaving this white cast. You’ll notice that it resembles a ‘splash’ pattern, or droplets. 

A healthy dose of rain will wash it off. Alternatively, you can wipe the leaves with a damp cloth – but there’s really no need.
