Water Quality

Having good water quality is the single most important ingredient required to ensure successful orchid growing. This cannot be overstated. At Slo Orchids, we have a reverse osmosis system, which eliminates any concern of salt build up in the potting media. Additionally, we do not have water spots on the leaves and in the hot summer weather we can spray the foliage and still have clean looking plants. Difficult orchids often become easy to grow when pure water is used. If you are not sure what your water quality is, you should get it tested. NEVER USE SOFT WATER FOR ORCHIDS!

Water Frequency

Generally we water all the orchids at one time regardless of genera. In summer, we water 2 to 3 times a week or every other day. If the weather is particularly warm, we will water spray the foliage every day without necessarily attempting to water the media. All watering is completed by 10:00 a.m., especially in the cooler months, to allow the foliage to completely dry out by the end of the day.


We fertilize at half the recommended dilution rate, every other watering that equates to once a week in summer and twice a month in winter. For general growing, we use a balanced 20-20-20 fertilizer with added trace and micro nutrients. For bloom forcing, we use a 10-30-20 or similar high potassium or phosphorus combination. Since we use reverse osmosis water, we have a deficiency of magnesium and sulfur, and therefore do a monthly foliar spray of magnesium sulphate also known as Epsom salt.

Hello! I just got my Slo Orchids plants tucked into their new pots / mounts. Thank you so much for the "bonus plant" that was a lovely surprise. I was also thrilled to see the E. tampensis and A. didieri are in spike/bud. What a delight! I really hope that they do not blast, so I can experience the blooms in the near future. They were packaged wonderfully and did not look stressed on arrival, so I am very hopeful. (fingers crossed) Thanks again for the beautiful plants. I will do my best to help them flourish.

Thank you very much for the new orchid. It is up to the standards of all of the other ones I have gotten from you. It is nice to do business with someone who cares about customer service. Unfortunately, it is a difficult thing to find in the world today. Thank you again.
