I know you guys rock at this so I'm posting again for help. I was happy to see my tree blooming and now I have mini green fruit (though I'm assuming most will fall off)

Recently though some of my leaves are yellowing before browning near the edges. The temperature spiked a ton recently so I dunno if that is a case. I'm still watering like normal and checking the soil consistency but I dunno if this is normal or not. I'm just starting to worry about these leaves.

Any ideas? Hopefully these pictures are ok these pics were taken between yesterday and today. My leaves that were yellowing have started to brown and I've lost some too.

What kind of soil is it planted in? Are you sure your watering it enough with the temps spiking? I have a grapefruit in a large pot and in the summer I need to water her twice a day on super hot days.

Thanks for the quick response. I might not be watering enough I thought I was but the temps jumped up so much today I was surprised to see the soil was so dry when I got home. It is planted in "基本用土" basic soil which is 7 parts Akadama (赤玉土) and 3 parts Humus (腐葉土).

Thanks nonetheless <3 I really appreciate the input. I don't know much about soil. Just used what the shopkeepers suggested. I had to translate it out just now when you asked. But I am watering it now and monitoring it.

Hi Ashley,

Its great to hear from you again. I suspect your little tree is drying too much. But, as the fruit hasn't dropped off, it could be a little sunburn too. Are you getting the leaves wet when you water? Are the yellowing/brown leaves on the outside/sun side of the plant?

Hi Daisyl!

It might be... I watered it, and I recently moved to a new place. Before I was on a south window now I am facing the east one. So I get a lot of strong light on sunny days in the morning before it moves on and it becomes indirect. I typically water close to the base and not the leaves, but I have needed to wipe down the leaves due to dirt collecting on it, typically I don't use water for it though.

They do seem more focused on the outside tho.

If one side of the pot was facing out in your previous place and now a different side is facing out, the now outward facing leaves aren't used to that much sun. It will adjust and new leaves will be fine. There's nothing you can do for the old leaves.

Keep an eye on the watering though.

If (when :smily:) you move again, mark the pots with a stick or a tag (even a piece of string tied to a branch) so you know what side faces out).

@AshleyD

I just had another thought. Do you have a saucer under your tree's pot? A shallow saucer would act as a reservoir to keep the soil damper. If you actually have a rainy season this year, you may have to move the saucer.

I do! Our rainy season has been kinda weird. We've been having an early start this year, and upcoming will be the real start soon (June is the rainy season in my area). Does this mean I should remove the pan altogether?

Also this morning when I went to check, I noticed mold on the top of the soil. I removed the soil from the top and sprayed some neem oil. Not sure if it will help though. I lost some more of the damaged leaves with the brown.

I'm confused. Is your tree inside or outside? When you water, does some water usually trickle through the drain hole?

Typically an outside tree, I temporarily brought it for 1 night. It is back outside where it belongs now. And yes the water drains through and collects at the bottom in the saucer. I will throw out the leftover water that collects.

I think the pot is restricting the roots. Citrus likes water, doesn't like wet toes. That burn could be sun or fertilizer. Your fruit will be with you until about our Christmas. You shouldnt have fruit drop...if you wipe the leaves, use a mix something like 1/3 cup milk, 2/3 cup water to wipe them with. Sometimes citrus leaves do drop. Have lost ALL the leaves on mine due to grasshoppers eating them, but the fruits grew on and the plant lived and leaves returned.
Should you go first, and I remain, to walk the road alone- I'll live in Memory's garden, dear, with happy days we've known.

It's plausible... I replaced the pot this past October making it a bigger one to expand the roots...

I read that sometimes younger green fruits drop because there are a lot and it is normal. Also temperature changes which could be a reason we are up in the 80s now unseasonably early...

I still have a good number of fruit on my tree though so hopefully that's a good sign...

Try adding soil to the pot by removing old soil as much as possible without disturbing the roots or repot. The soil looks depleted and the plant is not receiving enough nuitrents. Either it's getting too much water or not enough and dries out too much between watering. I would add a 1/3 the recommended liquid fertilizer each time watering. Inspect the root ball is it root bound? If so, open roots gently, clean out dead roots and check for inspects ie: nats or soil mites . Leaf rollers ? Also inspect leaves for insects. Repotting would energize the whole plant and only one size larger pot. Clean all dead material from plant rinse off the whole plant with garden hose. Dead material on plants causes a gas which also causes other leaves to die.

It needs at least 10-12 hours of indirect sunlight per day. Slowly harden off to outside temps ...day and night ...as well as sun exposure to full sun. Generally takes about 7-8 days for plant to adjust.

Happy 😃 gardening ooo !

Thanks so much for the response!

I just moved to an East Facing Window (well as of the end of March) and this is the first time my orange tree has flowered. I am thinking it is like you said and drying out too much between waterings since I had to change the schedule, I am gonna try to be more attentive. My orange tree typically stays on my balcony. I don't have a garden hose sadly so I just use my trusty watering can/bucket XD.

I cleaned up all the dead flowers and leaves I found. In terms of repotting, I talked to a local shopkeeper who knows me. They heavily discouraged repotting right now saying the tree is stressed and it would be better to wait. But we did buy some extra soil for mixing and a bigger pot for the next time that season comes up (There was a sale and I couldn't resist XD and it was better than buying a new plant...)

I think you are on the money though with the watering so we will see how it goes. I am gonna adjust first and see if it improves. I'll keep ya'll posted.

In the meantime here is some pictures!

Another update and wondering what you guys think. I have new leaves growing but still some burned spots and the paleness in the tips of some leaves does concern me...
