I have thought that over, and over-watering may be a problem, but my mix dries out so fast now, and it dried out even faster before I added coir to the mix. Montana humidity is extremely low, (I live in a "high desert".) What mix ratio do you recommend? I hate buying pre-mix formulas because they are the same ingredients we can buy separately and mix together for alot less cost. I can easily go thru 50 or 60 lbs of mix a season. The heat....the dang heat....I know that is my biggest problem! It could be 26 degrees outside, but as soon as the sun rises the inside becomes an oven...(perhaps my high elevation has something to do with it.) Last year I tried shadecloth, but it did not help. Since we get far more un-sunny days than sunny ones, the cloth made everything grow very leggy. And, altho it did cut down on the sun-rays it did nothing to stop the heat build-up. I keep the vents taped up because all the heat escapes during the night thru them if I don't. I cannot afford to heat the night air by untaping them until the end of april or so. When some seeds in a flat have germinated, should I turn off the heat cables? I use humidity domes too, but if I don't the mix dries out overnight. Regulating the temp in the grhse has been hard because the ambient temp may be one thing, but over on the shelves where the seeds sit, it is much cooler. But I'm thinking my judgement on "heat" may be humanized instead of plantized. If I'm standing in the greenhse and the thermometer reads a cool 65*, and I shiver, does that mean my sprouts are shivering? Would putting the fan on at night swirl the heated air around, or will it simply cool the air and blow it over already shivering plantlets? You guys are right....HEAT....I live in the mountains of Montana and heat is my worst enemy. I'm cooking my babies, aren't I? Can you give me your idea of what "heat" to us, translates to "heat" to a plant? Also, what is dry? If I touch it and it does not feel moist, is it actually moister than I think? If the top is bone dry, does that mean that 1" down it may be okay? One last note....all my veggies are thriving. My tomatoes, peppers, and greenhouse cuke are doing well. I dug up a bell pepper plant last fall and overwintered it, and got 3 good peppers from it so far and right now it sports about 8 more little ones. The seedlings that I started in Feb are all about 4" high and very healthy. Thanks so much for your help.

Could you upload your pictures to Photobucket or something like that? Then post those and your issues on the Tropical Fruit forum. There are plenty of FL folks there growing mangos. Without the pics and more detailed description, just impossible to diagnose.

It's just that it doesn't look like a mango leaf to me. Any possibility something else could have been in that soil? As long as the upper leaves are okay I wouldn't worry. Some plants do drop the first leaves after the mature leaves have developed.

dig a hole with a hand trowel ... AND FIND OUT IF ITS TOO WET OR TOO DRY ... crikey ... no more guessing ... adjust watering accordingly ... find out if the ball planted is wet or dry ... no tree .. recent transplant.. is properly watering with lawn irrigation ... long deep INFREQUENT soaking are imperative ... and that is not how you water grass ... also google mulch volcano ... and fix that ... one problem never answered .. until it dies and is dug up ... is how mangled the roots were when they dug up this extremely large tree and cut off 99% of its roots .. sometimes.. its just a massacre ... but your does have leaves.. it was seriously hurt .. but it is producing food thru those leaves.. and if you perfect and insure proper water.. it has a good chance of surviving ... you can not compare the one prospering.. because.. again.. all the important stuff is underground... ken
