What happened to using simple lime whitewash on the trunks where sunburn is a danger?

I dont know about lime but white latex paint/water 50/50 makes a better sunblock for bark than surround IMO. 

A fine dusting of surround on the foliage during a 105F+ heatwave makes sense to me.  Less than that, ai wouldnt bother. 

I may use a fine coat of surround on my watermelon plants this year to keep ants and aphids off them.  Problem is how to coat the undersides of the leaves.

Wise suggestions Brad.  I'll try and take is slow and perform "micro-coats", particularly on the branches, doing my best to limit  exposure on the leaves (if that's possible).  Here are some updated pics of my front-yard trees (2 of 3).  One of the three seems to be recovering and pushing out new growth (last set of pics), however the first two are still struggling.  I've no sense of new growth, and one has very yellow limbs showing.  :(










If you just transplanted them, its probably going to take some time for them to adjust and get established in their new spots.  I would just wait, this heat will make them grow.

When you want to offload some if that surround let me know. ;) Brad sent me some and I'll try it once summer rolls around but right now my trees are growing like weeds. That initial 90+ weather seemed to shock them but this week they've exploded.

Let me know how it works on melons brad.

Sure Kris.  I just purchased two bags to help with shipping.  If you want to split the price, you're welcome to one of the 25lb bags.  It would be nice to meet you and visit sometime.  You ever get into placer county?

I find it covers and sticks well to avocado branches and leaves at a rate of about 1 - 2 TB. per qt.

Great.  PM me before one of these weekends.  If the weather is good, chances are I'll be out in the yard working the "field."

At that rate I will never be able to finish 1 bag of surround, lol. Can it be applied with a brush as thick coat like paint on trunks without harming the trees?

That's not a bad idea (the surround painting idea).  I tried to spray my front-yard trees with surgical application, but it ended up getting everywhere and on everything within 10 feet.  It looks pretty terrible (especially all over the wood-chips), so I'm thinking about washing it away (if that works).  I think I would have been better off just painting the trees as originally suggested.  I do see how this stuff could work well in a situation where aesthetics were of no concern.

If you want to use a brush then go with a thinned white latex paint.

 ;D

I really like permethrin, use the Tenguard brand.  Sounds like an oxymoron but it's very low toxicity with a terrific knock down. Tough to kill grasshoppers will be on the ground dead in a minute after being hit with it.

Could be catipillars, grasshoppers, beetles,...  Usually you can look around and find the culprit.

I recommend you do some nighttime recon.

Grafted Frankencado continues to explode in growth, as does the sprawling volunteer tomato.  Sharwil, Lamb Hass, Pinkerton.



Finally some pollinators like this small dragon fly.

Lovely pic Mark.  Question, do you see heavy leaf drop in the Spring (or after post-winter seasonal warming) on your Avocado trees?  My outdoor trees seem to drop nearly 100% of their leaves over several months going into the Spring/Summer.  If they're happy, the put on new leaves and branching shoots to replace those, but there's a good period of time where the trees are brought down to a skeleton of itself.  Scary on a number of levels.

Look on the underside of the dropping leaves between the veins to see if you have Persea mites.  Otherwise just the usual salt burned leaves falling off to be replaced with this year's leaves.  Check back in July and all should be well.

Yep, it's happening right now but new leaves have been coming on for months.  New first, versus new later, may be variety driven.  My Reed is getting ready to dump big time.

Seems like the leaf drop question keeps getting asked.  Yeah its normal this time of year.  We talked about it May of last year in this same thread.
