The last week or 2 I started opening the top of my winterstorage so the plants would get used to the outside environment a little bit.
Today I took the storage away and the next couple of weeks the plants will stay in the garage in the same place with that little bit of extra light.
Today I took em out for the first time for about half an hour into the sun. It's about 18°C in the sun so I sprayed them enough to cool the leaves down whilst the pot got a little warmth.
When putting them back in the shade just in front of the garage I took some pictures.
I also took the opportunity to cut some dead stuff away and some buds before putting them on the pondedge for some sunlight.

Pic's:

Calamondin with the curled leaves...seems to have had a real blow by the forst just before I took em in.


closer look:


C. latifolia...this one had about 20 buds which suprised me since it lost allmost all of his leaves:


These were the only ones that stayed on and still grow, a bunch of young leaves:


C. Limon...the fruit grew about 2mm during winter but also lost all of its leaves axcept 1:


C. sinensis...last year completely bald and got better nicely and now this one kept quite a lot of leaves compared to the others:

I notice my key lime will drop most of it's leaves in the winter. In the spring it loads up with flower buds before it starts to leaf out. The key lime is in a 30 gal container.

About every three years I change the soil. I slide them out of the container & use a hose to blast away all the soil from the roots. I then cut back about 20% of the roots & repot with fresh soil & a lot of Osmocote. They never miss a beat.

A nice sunshine today so I took some pictures of my 2 lemon's which I am very proud of.
I always wanted to take some pic's right after spraying them with water...

The calamondin seems to suffer from heavy root damage as in the first pic's and I don't know if that one is gonna make it. I think all of its branches are dying back so my hopes are very low.

The sinensis is stable though no new leaves, no new buds. This surprises me actually since this one got through the winter looking the best of my 4 plants. Guess it needs more time just like my C. Limon.

And now the pic's of the Limon + 1 of the latifolia

The little one, about 1.2 inches (3cm) in diameter:


Again little Joe:


The bigger one, about 1.6 inches (3cm) in diameter:


again Big Jim:


And I'm starting to see some new flowers emerge at some places on my latifolia:

My Bearrs Lime looks a bit like your Calamondin, except that the heat vents were the culprits rather than the cold.

We renovated the sun porch and it has made it much warmer. Great for us, but bad for Citrus. Next year they go into the unheated basement.

Since the calamondin kept having twig dieback I already gave up hope and cut of the branches which were all turning...well yeah...dead .
This is what he looks like:


But when I looked closer I noticed this:




It actually has a young 'sprout' growing. :s I never thought I'd see any sign of life in this one but here you go.

edit: I forgot to ask...since all the branches are dead, will the plant be able to make new ones or do I need to do something special?

It seems the dieback has stopped.

It will survive! Let it grow.

You had luck with these trees. However, it is not a good practice to prune the frost damaged branches and twigs immediately, before the flush occurs.
Pruning dead branches in such cases usually leads to complete die back of the tree.

Best,
Igor

It's mostly the citrus physiognomy which could explain the whole process in depth... Personally, I always prune my citrus trees when at their peak, which is usually followed by even more vigorous flush. Pruning trees which suffered severe frost damage, just isn't the right thing in my opinion. Someone might think otherwise. I write mostly from my own experience, trials and errors.

Good luck to you and your plants!
Igor

Update:

Calamondin:


Sinensis:


Can't really figure out if thiese 2 twigs belong to the rootstock or the sinensis itself:


Limon:


Latifolia:


Mini Latifolia lime's:

Sven, both twigs, around the grafting area, seem to be right above the union. So both of them belong to the scion, sweet orange. However, if I were you, I would possibly strip those off and leave only the top branches to form the canopy. Good luck!

Take care,
Igor

Thanks for you reply .
Is there a way I can stimulate the forming of new branches and leaves? For instance: my latifolia has a nice bunch of leaves now but still not enough. Flushing stopped a while ago. It has some bald twigs as you can see in the pictures though they're still green. Should I cut these off or something?
I'm very new when it comes to cutting so I don't really now how to make it work properly.
All my plants are stable but I would like them to grow more branches and/or leaves.
