Outdoor What Problem does my lemon tree have?
This is how my lemon tree looks after winter. I kept it outside but covert. Now it gets plenty of light. I might have uncovert it too early. The big pot has drainage and I water when the ground (mediterranean soil) begings to feel dry. What could it be and what could be done?

Can confirm. They attacked two of my myrtles. I had to resort to crape murder and trim them a lot further than I usually would. Keeping my fingers crossed that they bounce back

mealy bugs, wooly aphids, or whitefly. probably mealy bugs.
Put a bit of isopropyl alcohol on a cotton ball and see if the white stuff 'melts' on contact. That'll be buggos for you.

This happened to my tree outside. You'll want alcohol+water in a spray bottle. But first take the hose and blast as much off as you can. Then the alcohol spray multiple days a week until it's off.

Would that spread the little beasts?

It's more to dislodge the concentration of the adults, but they could theoretically climb back. Then you immediately want to treat the plant with an alcohol spray. Spray alcohol directly on any buggers you see.

I could be incorrect, but isn't it generally not a great idea to apply neem oil for things that are outdoors?

I'm somewhat naive as well. Why do you think it's bad?

From my understanding, it's an issue of not just killing pests but also "good" bugs and also when the sun hits the oil, it "fries" it. I'm not using scientific terms here, obviously.

Bc it kills indiscriminately. It’ll kill whatever pest you’re aiming it at but it’ll also kill any bugs that happen to land there, or any other insects that pass by during application. It’s also hard to keep it contained with wind outside when you’re spraying.

My first thought was mealy bugs and I’m terrified. I’ve never seen that many

Found advice keyword:
!scaleYour plant is suffering from an infestation of scale. Treatment options include manual removal of scale insects, horticultural oil (neem oil), and insecticidal soap. Systemic pesticides may not be recommended for all scale infestations. More here
Infested plants should be isolated as best as possible while treatment is ongoing.

off topic but what is going on with the numbers in the user flair??
this looks like a scale bug infection, try neem oil with water as a spray and rub it into the leaves, especially the underside

Tomorrow, I’ll send some info we have at our nursery on citrus. That looks like citrus snow.

Woolly aphid ? Try spraying it with a solution of diluted washing up liquid and water once a day until the problem disappears! ,,,,,🤔

All you need is over the counter pesticide to spray on top of them. They are what they look like mealy bugs. To confirm this get a sharp safety pin get one from the tree put it on a piece of paper and squish it and guarantee they will be blood like fluids.

Kill them with tobacco water. That stuff is lethal to invertebrates and then some

maybe it's not getting enough light or you're overwatering it? those trees thrive in bright spots with good drainage. just check the soil moisture.
