Hi, William! Your plants look great! I think the pot size is fine for now, but, you can gently slip one or two out of its pot and get a look at the roots to see if they are growing down and around the soil, and holding it in. If they are, and they are starting to circle, it is time to move them to a pot that is at least few inches bigger in diameter. One pot size up. It is better to up-pot now, than in the winter if you can. You will have them under lights, but, will you be letting them go dormant during the winter??

Some folks don't like growing citrus in Clay pots (I started out with clay) because they dry out so fast, but, it depends on where you live, climate, and how often you plan on watering them. When you upsize, you could switch over to plastic pots, which are easier to monitor for water issues. And, they are lightweight ..

I am sure you will get great advice from the pro's on here shortly. You are doing a great job so far!! Nice varieties! !

Hey jinnylea thanks for replying! I did unpot the mandarin since it had the most roots coming out and the roots at the bottom were indeed circling around a little so I teased out some of the roots that were circling up and potted up in a slightly larger clay pot.

I didn't know citrus go dormant! I had my ponderosa lemon under lights last winter and it had a few growth bursts so it didn't seem dormant at all and since the plants will be under those same conditions, I guess I will not be having them in a dormant state.

I was using foliage pro early this summer but I got a little lazy about mixing the fertilizer so I've been hosing them all down with Miracid until the soil is saturated. I don't know if it's the best fertilizer for them but since I started doing it some of the foilage has gotten huge.

Unfortunately the variegated calamondin's has not been as vigorous as the other plants; the leaves and branches that grow from the main plant are very small for citrus leaves. My guess it is due to the lack of chlorophyll but I have the plant in as much sun as I could possibly give it. :(

Don't keep your trees next to or on the grass. Grass gives off a gas that will slowly kill citrus. You can paint the pots to reduce moisture loss.

William...Use vinegar and you won't believe how much better they will grow and how green they will get))

Hi William! I agree with Mike that you can go either way with the pots (very nice plants by the way!), I always lean towards potting them up. I recently potted up some that had roots wound around like yours and they immediately started growing again. I would definitely go with plastic pots though...much lighter, easier to manage, and they hold in moisture better. I have always found variegated plants are not as vigorous as their green counterparts, so I would not kick yourself about that. I am glad to see that your plants from Loggees are doing so well...I have a couple from them myself.

Thanks everyone..! How much vinegar should be used and how often? And are you talking about white vinegar or apple cider vinegar?

Laura: I think you're right about plastic. I am going to switch them all up once I repot them. They are already heavy and they are not even in big pots!

William, buy yourself a cheap pH testing kit (for aquariums - they are like $6 on Amazon) and check your water 1st after adding FP, then again after adding vinegar until you get it to about 6.5...I would add at 1/2 tsp intervals until you get there. If it's a little below, don't worry, they'll be fine. And yes, white vinegar, but when I started I used apple cider because it was what I had and it worked just fine.

William, I find my variegated trees do better in a little less sunlight than the non-variegated. Try moving it into a little bit more dappled shade and see if it does better.
