This is what "leaf scorch" looks like

I guess this is probably more for newbies that are rooting for the first time this year, but it may be helpful to others also.

The topic of "leaf scorch" has come up a lot - and I have suggested that you should always "harden off" your trees if they are started indoors -- you must gradually introduce them to full sun to prevent burning the leaves.  This "hardening off" process is usually done by putting them in filtered sun for a few days (under a tree), then gradually giving them an hour of sun for several days in a row, then for two hours, then three hours, etc.

I am going to show you why you should NEVER put indoor plants out into full sun for several hours, even if they have seen "full sun" from a window (many windows filter UV rays, and so do window screens)

The attached pictures show what leaf scorch looks like.  These are some of my plants rooted a couple of months ago that I took outdoors for the first time.  I couldn't get lattice up to shade them in time, and they saw about 4-5 hours of full sun one day (one day, 5 hours, that is all it took). 

The white "scorched" (burned) areas are circled in red so you can see what happens.  Eventually, this part of the leaf will dry out and fall apart, and the leaf will probably curl up, crinkle and fall off.  I will try to remember to take pictures later to follow up.

In severe cases, and for some types of plants, the leaves will turn completely white, and fall off.

Think of the difference if you are standing in full sunlight, versus standing in bright sunlight, but in the shade. Same thing goes for plants. They don't use sunscreen - they have to get used to the light a little at a time.

I really burned my leaves last year.  Figs seem to have a strict growth cycle.  If you lose leaves they don't seem to be able to just quickly put out new growth.  I have absolutely no partial shade.  I either get the full morning sun or the full afternoon sun.  The only thing I can do is keep the plants on the Northwest side of the house so they get the weaker late afternoon sun.  I have to build something for when I need to transition plants.  I want to take the two I have in the windows outside.

There are some nifty inventions out there, including shade cloth.

Just make sure you support properly and watch closely for puddling during your first couple storms ;)

Thanks for the pictures Jason!  Unforunately one of my babies has crispy leaves but good to know it's the sun and not something else crazy!:)

It happens ... the leaves affected are permanently bleached on the plants you see above, but new growth is starting perfectly fine!
