I have a moisture meter that registers readings from 0.0 to 9.9 (driest to wettest). I cannot find a listing for a potted avocado tree. Can you give me info as to what percentage is optimal for the plant? I'm not that good at pressing on the soil and figuring it out from there.

    growing indoors or out? Full sun or partial? How old is the plant? How tall is the plant? How about a picture? Help us help you...

  • Which meter are you using?

Without knowing what meter you are using, and whether the readings are linear or not then, one would have to guess.

It's recommended that avocados be watered 3 time a week to simulate what happens in their native environment, and potted into a free draining soil. This is important as the roots can rot if submerged for a day. However the pot should not be allowed to dry out completely.

If the tree is potted into a sandy loam soil, then your meter should read towards the moist side eg. 8 but if in a loamy soil, then aim for near mid way eg. 6. The corresponding tensiometer readings are 20 cb and 40-45 cb where 0 cb is when the soil is saturated.

  • For a potted plant that may be indoors the watering guidelines may be different..

  • @kevinsky are you saying moisture readings are different Mar 7 '16 at 17:31
  • For indoor potted plants? Mar 7 '16 at 17:32
  • All that we know from the original question is that the plant is in a pot. That leads me to suspect it is growing indoors. I suggest that any indoor plant that is watered three times a week is probably getting too much water unless it is in a greenhouse.

  • @kevinsky, it depends on the mix. On a long cado thread elsewhere they use a gritty mix, and water daily, and fertilize weekly fire their indoor cados. The meter will help. Mar 7 '16 at 17:37
