Questions & Answers

Question  My wife and I have be following your informative shows on the channel 2 and we have noticed the recommendations about fertilizing Orchids. What we have caught up to now, is that the fertilizer to be used has to be a 18-18-18 or 19-19-19 fertilizer and it have to be used once a week. Please tell us how much of this fertilizer to a gallon of water, as we believe that the fertilizer shall be diluted in water before being applied to the Orchids. Any other tips regarding Orchids would be appreciated.

Answer With respect to the choice of fertiliser a general purpose water soluble fertiliser would be best. The analyses should either be 18-18-18 or 20-20-20. We utilise the latter and follow a regimen of fertilising once per week after waterings. Remember never fertilise dry plants as you would leach them and may kill them. We also fertilise every two weeks with a blossom booster (for mature plants ) this would be indicated by an analysis with the middle number being the highest. You also asked about the ratio of fertiliser to water. Ideally it should be a teaspoon to a gallon of water.
