My pineapple has all these white things on the older leaves .. none on new leaves. Is this normal or is it a disease?

Hm, none of my pineapples have that, Anne. I just walked out and checked them.

If it was a disease, you'd think it would continue on all the leaves. It looks like some sort of insect damage to me, like the green layer has been chewed away. Thrips, maybe? They sort of scarify the top layer of the leaf, don't they? In any case if the new leaves are ok, I'd just keep an eye out and carry on. The bugs have moved on to 'greener pastures'.

Thanks for the reply .. I was thinking bug damage too but couldn't find any .. anywhere .. which was really nice because usually this time of year I'm in a pitched battle with bugs in the greenhouses .. first year this hasn't happened! Loving it!

Not to predict gloom and doom here, but the bugs may be waiting for it to warm up, too. Keep your eyes open!!

Down here, when it gets cold, that's when we have lots of bugs trying to come into the house for warmth. As soon as we have night temps predicted down into the 40's that's when I have to don the HazMat suit and spray around the house perimeter. But . .. this is an older house with lots of cracks, so I've been having a terrible time with ants this winter.

Once we get warm enough to turn on the a/c they really like it better outside and head on back to the warm, moist garden. Come on Spring!!

I've found diatomaceous earth works for ants .. I'm always finding them in pots so when I mix up some potting mix I also include DE in the mix and it works really well for about 3 months. It still works when it's wet too.

Oo, thanks. I'll try that. My pots get infested a lot, too.

Much rather use that than a chemical. Even the baits don't work half the time. Ants change their diet unpredictably . ..
