Should Phalaenopsis orchids be given nutrient solution in summer, and how often should it be sprayed?

In summer, as temperatures rise and Phalaenopsis growth speeds up, its nutrient needs increase accordingly. So, do Phalaenopsis orchids need nutrient solution in summer? And how should the spraying frequency of the nutrient solution be determined?

We all know that summer is hot and stuffy, and people lose their appetite - Phalaenopsis orchids are pretty much the same! At this time its growth rate clearly slows down, not growing as vigorously as in spring and autumn, and its demand for nutrients is reduced as well. But this does not mean you should stop feeding nutrient solution completely! Just like in summer we eat less but still occasionally need a glass of juice to supplement vitamins, Phalaenopsis also needs a little nutrient solution in summer to maintain basic nutrition. If you cut off its food supply entirely, when autumn comes and the weather cools down and it wants to grow new leaves and send up flower spikes, it may not have the energy. So, using nutrient solution on Phalaenopsis in summer is something you should do, but not the old way!

Key point! In summer you cannot copy the spring and autumn frequency for spraying nutrient solution. In spring and autumn Phalaenopsis has a good appetite; spraying diluted nutrient solution once a week is fully absorbed. But doing that in summer is like force-feeding it and can easily burn its roots! Generally, in summer2 - 3weeks between sprays is fine. The exact number of days depends on your environment - if indoors with air conditioning, keeping the temperature around25°C, the environment is relatively cool, and2weeks between sprays is no problem; if the room is hot and stuffy with temperatures above30°C, then3weeks between sprays is safer.

There are also little tricks when spraying nutrient solution! Never choose high noon under the blazing sun to spray - Phalaenopsis cannot take it! Choose the cool morning hours, or in the evening after the sun goes down; at these times when you spray the nutrient solution, it can slowly take it in. When spraying, do not just focus on the leaves - spray the aerial roots too; these aerial roots, like little whiskers, are the main force for absorbing nutrients! In addition, the concentration of the nutrient solution must be diluted properly; if the instructions say to dilute1000times, never cut corners - better too weak than too strong!

Finally, a reminder: when growing Phalaenopsis, if you find the leaves turning yellow and the aerial roots shriveling, it may be that too little nutrient solution was given; if the leaves develop scorched edges and the roots rot, it is most likely too much. Quickly adjust the frequency and concentration to rescue it! Master the rhythm of feeding nutrient solution in summer, and when autumn arrives, your Phalaenopsis will surely burst out with flower buds.
