Struggling Potted Lime Zone 5

8 years ago

Is it time to get a grow light and set up an ICU for this Lime tree? Here in Upstate NY the temperatures are steadily dropping and I can only get it about 4 hours of direct sunlight a day.

I received it with a strong case of scale and spider mites, in old poorly draining soil and set out to revive it. I've learned a lot along the way about house plants in general, and subjected this to some stress.
This is it after a long session of wiping the whole thing down with some alcohol to get the scale and mites under control.

It unfortunately continued to deteriorate, all the leaves showing yellowing similar to those big 2 ones off the lower branch.

I bare rooted it and put it into some Miracle-gro Citrus & Cactus with not enough extra perlite, and watched as the soil continued to stay wet for days. I noticed one of my Sansevierias showing signs of root rot in the same batch of soil, and that made make some Gritty Mix to transplant everything into.

So I bare rooted the poor tree again, but it was quite easy since it hadn't taken hold of the new soil yet. Then potted it into the gritty mix.


Over the next few weeks, the few new growth sprouts fell off and all the leaves continued to yellow and fall off until it looked more or less like the first photo.

The new growth leaves are taking a long time to grow, they're about 2 months old at least.
I'm imagining putting a cut out bucket over it with a grow light over it, would this be the best way to help it?
I just want it to be healthy.

    The tree looks good overall and I would agree that it needs more light. I am giving my grafted Fukushu kumquat 6 hours of lamp light starting at sunset. I has proven quit valuable. The tree is growing 3/4 inch per day at present time.

    was it an accident or you wanted to break that citrus

  • 8 years ago

    The citrus was broken intentionally to encourage the new grafted bud to grow. While the tree rejects the main trunk because of its damage, the rootstock top still produces food for the tree. The grafted bud is positioned and given extra light so the roots put it energy into the new bud/branch instead of the damaged broken top. The tree will discard the old top when it is done with it. Most people will cut the old top off after the bud gets a good amount of growth. I am not though.

    poncirusguy,

    Thank you very very much. I am learning. Best wishes.

    Steve, bud53 is grown in to a beautiful young tree :)

    Hi Matt, are you sure you know how to use the gritty mix to its full potential?

    What did you use for ingredients and how do you know how often to water? It's a trick and it takes time. I have never got the knack for it to this day, so I play it safe and use the 5.1.1 instead. I must say going from a bagged mix to gritty can be very different.

  • 8 years ago

    I used screened 1/4" reptibark, screened turface, and screened chicken grit.
    It's taken some getting used to. When I'm in doubt, I stick a skewer in for 15 seconds and test it with my lip.
    Seems my plants only need watering about once a week or once every 2 weeks.
    I killed a lemon seedling by leaving it out when we got rained on for a few days straight. It rotted the roots. So I learned you can still over water.
    My other identical seedling survived and gets watered bi-weekly and is doing well.

    So, getting the hang of it I suppose. All my plants seem happy in it since putting them in it about 3 months ago

  • 8 years ago

    This tree looks the same as it did a month ago, with just 4 good leaves. but I just noticed what looks like the start of flower buds at the tips of some of the branches.
    Should I pinch these off? I'm afraid any energy not spent to growing more leaves is going to kill it.

  • 8 years ago

    Matt, if you are taking good care of it and not overwatering, give it time to come back. I remember once I waited for 2.5 months for a lemon tree to leaf out. Give it lots of light, not scorching sun, warm roots and it will leaf out.

    My sweetlee tangerine tree was killed in the winter of 15/16. I came up from the roots 6 inches under july 2017 taking 1.5 year to recover. Wait

  • 8 years ago

    Should I leave the flower buds be? Thats really my main concern now, I'd hate for it to waste valuable energy on flowers as a 'last hurrah' if it could instead be diverted to leaf growth.

    Matt, I know what you are thinking and feeling right now about that tree :)) post a picture of the tree with flower buds, let's see how many of them are showing up.

    Show us your container as well.

  • 8 years ago

    Here is what Oscar Tintori one of the worlds foremost container growers says about terracotta pots for citrus growing.

    "The choice of pot, whether plastic or terracotta, is obviously up to the individual. Bear in mind, however, that a plastic pot although more practical, may cause the soil to heat up more in the hot weather and get colder in winter. A terracotta pot on the other hand, will enhance the beauty of the plant, is more resistant to temperature change and will allow the soil to transpire more efficiently."

    Silica, I am not against terracotta pots, l like them, as long as they have lots of holes in the bottom.

  • 8 years ago

    Silica - Terracotta will get colder in winter than a plastic pot because a terracotta pot transpires resulting in evaporative cooling while a plastic pot does not transpire at all.

    Sunshine, my Oscar Tintori post had nothing to do with you. People on this forum seem to have negative positions concerning terracotta. I, as you, like growing in terracotta, Personally, I have never had any problems with terracotta. Going to Tintori's web site one can see all of Oscar's trees and the lovely terracotta container s they are in. Few in this world have more knowledge and success with container citrus than Tintori.

    Vladimir, cold should never be a problem with container citrus unless you leave your trees outside during the winter season. A home or greenhouse should be plenty warm for a container---- plastic, terracotta, or wood. Anyway, I was only pointing out what Oscar Tintori had written in his book.

  • 8 years ago

    Silica, although terracotta are colder than plastic pots, I am not convinced it matters much when it comes to growing citrus.

    Here's the 2 main stems with buds, theres a few tiny branches with some at the end but not as many or the size of these.

    It sits in a terracotta pot in a room that tends to stay around 70-80 degrees, although the bay window area will be somewhat cooler. I'm not convinced a plastic pot in this scenario would be much benefit over the stress of repotting.

    Looks Ok, now wait and don't make wrong moves:)) meaning disturbing roots, overwatering or underwatering. Giving it an adequate light will make it to leaf out, you can remove the flower buds. Do you have fertilizer in the growing mix?

  • 8 years ago

    big thorns on a little twig?

  • 8 years ago

    I fertilize with foliage pro, 1/4 teaspoon per gallon.
    I'll thoroughly drench the soil in my shower with a spray head, and then after it's sat for about 30 minutes and drained, I'll water again with the fertilizer.

    Seems to be working OK for all my plants so far.

    Up the feed to 1 teaspoon per gallon.

    More than 1/4 is needed, more like tablespoon or more, just as Steve say's for the active growing season...1/4 is a good amount for the winter when growth slows unless you have them under lots of strong lights though...)
