Correct watering methods are necessary for avoiding root rot and dehydration. Enthusiasts often struggle with determining the optimal watering frequency. I've killed plants by both overwatering and underwatering. Your watering method needs to be adjusted for seasonal changes and other environmental conditions. Being properly hydrated will help the roots remain firm and green, and will help keep the leaves from becoming wrinkled.

Seasonal Adjustments

  • Summer: Water weekly during active growth phases
  • Winter: Reduce to monthly during dormancy periods
  • Spring/Fall: Transition gradually between schedules
  • Monitor temperature changes affecting evaporation rates

Potting Media Differences

  • Bark mixes: Require watering every 5-7 days
  • Sphagnum moss: Holds moisture for 10-14 days
  • Charcoal-perlite blends: Need frequent 3-4 day cycles
  • Check media dryness before every watering session

Environmental Influences

  • High temperatures increase watering needs by 30-50%
  • Low humidity requires more frequent hydration
  • Air circulation accelerates drying time
  • Pot size affects moisture retention duration

Always check media dryness before watering

Using the finger test method, check the reservoir level before watering. You insert your finger 1 inch into the media. When it is scorched, you can water the azaleas. Do not water on any rigid schedule. My orchids in terracotta pots require more frequent watering than those in plastic containers. Watering should never be based on a schedule, just on what is happening at the time with the orchids.

The quality of water is paramount. It is essential to use room-temperature, filtered water, as cold water can shock the plant's roots. Hard water can cause unwanted mineral buildup. I prefer to use rainwater for optimal results. Always ensure that the entire pot is drained after soaking in water. If you achieve this, you don't have to worry about your plant developing crown rot.
