Looks like spider mites; you won't see them without a good magnifying glass. A good wash outside or in the shower will go a long way to getting rid of them. My advice... lose the fertilizer spikes and replace with a good soluble citrus fertilizer applied 3-4 times per year according to the label. Your tree looks to be a little underfed; and unhealthy trees are more susceptible to spider mites. I would also get a good foliar fert. and give your tree an application of that about every 15 days; I like Bayer Bayfolan Forte; lots of container growers here use Foliage Pro... there are others. Your tree looks a bit leggy; I am guessing it gets less light than it would like.

Jennifer —-(Spraying with Neem Oil and or and other mixtures to eradicate the insects organically could still harm those beneficial insects. Some people will just let those pest stay on the tree because they dont want to harm them. Its a difficlt choice to make for some and you need to understand that some bad infestations that might get out of hand and could cause your trees to become weak and allow other diseses to slowly kill your tree. i always try and let Mother Nature work on the right balance of the pest verses the beneficial insets to keep everything in check. But sometimes i will have to step in and use more than organic to combact the problem. its up to you to decide what is best for your tree. Laura Even those that eat leaves ___ Katydids 🌺

Yes, so cal San Fernando valley. The fig's ph tested at 6.75, which is within the range of N absorption. My water is pretty alkaline at 7.9 so it tends to counteract all the acidity I put into the ground with compost and fertilizer. the tree gets plenty of water, I test monthly with a probe. my cure-all is worm tea, but I'm worried a shot of N right now will be a killer in the heat. i'm going to try a heavy watering in the morning. my wife is sort of devastated as the figs are turning mostly inedible. Past years were super sweet and tasty (big thumbs up on the V de B) and we had a huge crop coming this year.

Until the soil gets warmer, there is little point in worrying about nutrients, which are locked up when soil temps are below 45F. Good luck!
