Fiddle Fig Leaf question

4 years ago

Can anyone tell me why i have these dry crispy places on my FLF ? i had this tree for almost 2 years, planted in fast draining soil watered every 10 to 12 days. it has double in growth, since i have had it. Also to Al, once June comes, should i leave it alone or do a root pruning? You helped me with my tree when i first go it and root prunning was done then. Thanks. Please be patient with the picture posting, if i had to do multiple post. seem to always have problems.

    The images look fine. Good job.

    The necrotic areas on the leaves shown is likely caused by over-watering. How do you determine when it's time to water? Are you familiar with using a "tell" to "tell" you when it's time to water? When you water, are you making sure the entire soil column is getting moistened and at least 20% of the water applied at each watering exits the drain hole? I ask that because salts from tapwater and fertilizer salts can accumulate in the soil to the point where it makes it difficult for water to move into individual cells. It is essential that the level of dissolved solids (salts) in the soil solution is lower than the level of dissolved solids in water within cells if water is to move through the cells membrane. When the level of salts is too high, it limits water movement into cells, and can even pull water out of cells by the same mechanism curing salts pulls water out of meats like bacon, ham, salami, ..... . This causes plasma to be torn from cell walls as the cells collapse, killing the cells. The technical term for this physiological disorder is called plasmolysis, but it's commonly called fertilizer burn.

    The above is not to say I think it is fertilizer burn, only some watering habits and a high level of dissolved solids in the soil solution can work in concert to limit the plant's ability to move water efficiently to all parts of the plant. Over-watering causes the same symptoms as under-watering; this, because under-watering limits the soil's oxygen supply, which in turn limits the roots ability to do its job of taking up and moving water to all the plant's organs. Even when the roots are awash in a sea of plenty, the plant's chemical messengers can be "fooled" into informing the plant it is in a drought situation.

    To tell whether of not your plant needs repotting, lift the plant from the pot. If the root/soil mass comes out of the pot as an intact mass, it's time to repot when it's next most appropriate, which would be in the 2 weeks before the summer solstice in most parts of the Northern Hemisphere.

    What are you fertilizing with/ how often?

    Hey Al, yes i am using a tell. it goes all the way to the bottom of the pot. i leave it in the soil overnight and water when there is no soil on the tell and it is completely dry, usually this is about 11 days out from last time it’s been watered. i water throughly and have a wick that further drains the water and it’s in a clay pot. i was using the pro foilage whenever i watered 1/4 tsp per gallon of water but i stopped that a couple of months ago, just didn’t put it in the water. Don’t know what else i can do except push the watering out to every 14 days if overwartering is the culprit, what do you think?

    Over-watering is much more common than under-watering, but allowing the medium to go completely dry might mean you need to water sooner. Try watering when you can barely detect moisture on the tip of the tell, and make sure you're wetting the entire soil column and flushing the soil as you water. You might want to consider going to 1.5 - 2.0 tsp FP 9-3-6 per gallon and fertilizing every 5th time you water in the winter and every 3rd or 4th in the summer. To keep track of what plant needs to be fertilized at any given point in time, drop a marble/ button/ cement block in the pot each time you water. When you're about to add the 3rd/ 4th/ 5th item, you'll know it's time to fertilize, depending on the season and how often you've determined you should water. Everything else sounds good.

    I was kidding about the cement block - just seeing if you're paying attention.

    Thanks for the advice! Sounds good. I just saw this as i was reading the current post about the FLF. I spaced entirely about the cement block! Ha Ha!
