Hello guys I'm new to the forum and joined because I wasn't finding the answers I was looking for.

I bought this orange tree during the spring and repotted it as it had outgrown it's pot. A few days later it blew up with new leaves and about 2 months after that it started growing fruit. It's coming to the end of the summer here in Ontario but we are still having 40 degree celius days, the humidity has been out of this world this entire summer. I have noticed some of the leaves getting yellow spots and some have fallen off or started to curl. I have also noticed the soil is not drying out like it was earlier in the season. What could I be doing wrong? Here are some pictures unless I posted then wrong .






Secondly I have a 15 + year old lemon tree that has never Grown fruit, anything I can do to help it along? It grows new leaves in abundance every summer.





And last but not least I planted a few brown turkey fig trees this spring, both were around 4 inches tall and are now about 2 feet tall. I'm scared to try and keep them in the ground with our harsh winter so I dug them up and transplanted then in containers to store in my garage . The root system they grew was pretty vast. But one of them seems to still not have recovered after about 4 days on now. and it's only 1 of it's branches. The other question I have is why this branch in particular has solid leaves while all my other branches have the typical fig leaves. Could it be a different type? From what I remember there was more then one sapling in each pot when I bought them and they had kind of grown together.




Thanks in advance

I'll try to answer.

Leaf curl in many plants, citrus trees included, is a sign of distress. Judging by the picture and other symptoms, I'd say your problem is due to watering. Citrus trees are very water-intensive, but they don't like having soggy feets, meaning they need excellent drainage, especially when potted. A poor (which doesn't mean cheap) potting medium is usually the first cause, followed drainage holes getting clogged by dirt.
You also mentioned 40°C highs ( we are having 27°C at very most now and tomorrow a further drop in temperatures is expected) but how hot/cold are nights? Also have your citrus trees suffered from any parasite recently? Bugs love to feast on their leaves, causing all sorts of issues.

Now let's move to the lack of blooming. Generally speaking citrus trees fail to bloom if one or more of these conditions happen:
-)Winter night temperatures over 10°C
-)Lack of water in late Winter (January-February)
-)Lack of sunshine
-)Excessive nitrates in the ground (due to water content or excessive fertilization)
Check the list and see if it applies to your lemon tree.

Finally the fig tree... yes, they do develop impressive root systems quickly. That's part of their survival strategy.
A particularly impressive root system may also hint your fig tree is grafted: check if there's a notable "junction" on the trunk anywhere from 1" from the ground and up. Fig trees sold in cold climates are often grafted so that would explain a lot.
Rootstocks are often "franks" or "volunteers" meaning plants obtained from seed, which usually are highly variable in fruit quality but are extremely tough and adapatable as far as soil conditions go. It's not uncommon to see volunteers sprout in the most unlikely places after traveling there in some bird's digestive system.

Thank you for the advice. I think I'm going to have to transplant the orange tree, I ran out of cactus soil (only thing I could find that was well draining ) so I had to mix it with normal potting soil. Could my old lemon tree also not be blooming because it was planted from seed?
As far as the fig tree goes is there a particular variety that has solid leaves?

Matt, if you can't find cactus soil, you can always use perlite. pumice, or granite chicken grit to regular potting soil...about 50-50. Don't use sand as it's too fine. You may be over fertilizing your citrus trees and you should use citrus specific food for them. Too much pushes green growth at the expense of fruit.

I was warned early on that while it is tempting to repot a tree into a large pot, citrus trees should remain in their pots until rootbound then gently moved to the next size up pot. 3 gallon to 5 gallon, 5 gallon to 7 gallon, etc., or the tree will concentrate on growing roots instead of flowering. Also, I feed heavily in the spring, bloom food and Osmacote. Currently have 10 oranges on my Satsuma Orange tree but only 1 lemon on my Improved Meyer Lemon. But I also hear they they fruit heavily in cycles every other year taking a break? Not sure I believe that? My Mei Wa kumquat has bloomed in cycles all summer meaning I will get lots of kumquats at different times. It was repotted from 3 gallon to 5 gallon last spring and needed it badly.

Watering well gives you juicy fruit but over watering will hurt it. And of course, the more sun the better. Keep us posted.

I decided to repot them with some better draining soil and they are drying out between watering, instead of stay wet for a week at a time. I'm also wondering now if the amount of humidity we were getting here wasn't allowing the moisture to evaporate.

Also was curious to know if it's normal for a Meyer lemon to produce big clusters of between 15 and 20 flowers while it's already flowered months ago and producing fruit. I don't know how you tell if it's a Meyer, it was given to me by a neighbor in pretty rough shape.
