Help - bark splitting Little Gem Magnolia + Redbud

9 years ago

Hoping for some input from the tree gurus here about what could be going on with my Little Gem and my Forest Pansy Redbud because I'd hate to lose either one.

The magnolia, approximately 6 1/2 ft tall, has been planted for just over a year. It's always been a bit sparse but healthy looking overall. About 8 weeks ago, I randomly noticed two areas where the bark appears to be splitting open -- one near the top 1/4 of the central leader and a second, on a thinner side branch. The tree is planted as a focal point in the middle of an eastern facing bed in my backyard and gets full sun (fairly intense 8b/9a sun) from 9 am to 3:00 or so. It's hot and humid here in coastal Mississippi and these "splits" are on the sun facing side. I was freaked out when I first noticed them but the tree is putting out new growth and has flowered a little. Earlier in the summer, I lost several clumps of new leaves -- they'd suddenly brown out and droop and die -- but that's been happening less now. And the leaf issue was not on the affected limbs.I am very conservative w/fertilizer and only applied Plant Tone in the spring followed by two applications of half strength 10-10-10 liquid this year so I wouldn't think the leaf issue was fertilizer but I could certainly be wrong.

The Forest Pansy redbud was planted in June. It gets part sun and is somewhat sheltered by my neighbor's huge live oak and an old pecan tree. It's a lovely tree but a little top heavy at 8.5 feet tall and is currently staked. It looks fine but hasn't had any significant growth (above ground, that is... hopefully the roots are doing their thing). This morning though, I just happened to notice one of the redbud branches has the same kind of "splitting" action going on -- looks identical to the ones on the magnolia -- but that branch is not getting blasted by direct sun.

I am thoroughly mystified (as is my yard man) and more than a little worried. There are no sprinklers in my yard and these lesions are high up -- so they're not weed trimmer damage.

I've yet to master how to post more than one photo at a time so will add some in subsequent posts. This first picture is the redbud limb. Bad angle but the branch is significantly over my head and hard to photograph.

Any ideas? Is this serious?? Thanks in advance...

Pic 1 of Little Gem magnolia. And I forgot to mention but all of these limbs are on the small side -- 1" - 1 1/2" in diameter max since both are young trees.

i suspect.. that 3 months ago.. was a bit late in regard to proper tree planting time in TX .. increasing transplant shock .. even if done by professionals ... however.. a few more months .. further back .. put the second one more into the PROPER planting time .... shall i presume the second was also as large ... because if it was smaller that also reduces transplant shock ... i understand you have an exceptional emotional attachment to this one .... and you are concerned ..... and you are worried.. but i just dont know what more you want from it.. if it has green leaves .. its alive .. i expect nothing more.. for the first 2 years after i plant a tree/shrub/conifer ... on this expectation.. i am never let down .. and often .. they surprise me by doing more than i expect ... but often.. they just sit there ... presumably growing roots ... and more importantly.. if the buds remain green and viable.. you are simply going to have to wait for it to get its act together ... there is nothing you are going to do.. to a large recent transplant.. to make it perform any better.. or any faster ... just water properly .. and make sure you do not drown it in clay soil .... try to be at peace with it ... and good luck ken

I've seen lots of DDB, it is a popular landscape tree in the SE. I've only seen one EB, my tree. EB's main claim to fame is it's supposed hardiness. Mine is in full sun and wide open, no large trees anywhere near it. It is about 20-25 years old from a one gallon. It is wider than high, branched to the ground, and fairly open with somewhat long willowy branches. It took a long time to bloom, and is even now a rather shy bloomer. Blooms are of average size. For me EB has been of average hardiness, it has never lost any wood or suffered any bark split, but it has had browned foliage, though never defoliated. On a scale of 1-5 I rate it 3. DDB is very popular and often seen in private landscapes and especially public ones. It is upright in youth and more spreading as it ages, but taller than wide. Foliage is deep glossy green above and copper/red beneath, especially when young. The tree presents a lush, rich appearance and is a vigorous grower. Floriferousness has been average, but blooms are well formed and slightly smaller than average, a good thing IMHO. Hardiness has been on a par with EB for me, the literature says less hardy than other hardy clones, zone 7. On a scale of 1-5 I rate it 5. All magnolias grown under conditions you describe will tend to be open, with slightly larger than average foliage and less than average bloom, all due to shade. If DDB and EB are the only clones under consideration, my choice would be DDB.

New Forest Pansy Redbud tree with trunk wounds - need advice
Q
Comments (8)
Thank you so much for your help! I have included the photos you asked for below. Our landscape designer recommends that we keep the supports in place for around one year and take them off somewhere around Nov. 2016. So you don't think we need to ask for a different FPR tree? Are these common enough problems that we might end up with similar issues with any FPR tree we get? Thanks again so much! Here is picture of the full trunk. The split wound is at the very top middle of the pic., to get an idea of how each of the wounds are located to each other. Here is a close-up of the bottom of the trunk. Here is a better picture of the support lumber from the side. And, here is a close-up of how the support lumber is attached to the tree. Just let me know if you or anyone else would like to see any other photos of the tree to give us advice. ~Thanks!

I just found a black tulip magnolia here in Colorado and fell in love. i didnt purchase it right away but my husband brought it home as a surprise to me. Im not sure where to plant it or how to amend the soil. can you describe what you have done? Also how do you teepee it? Do you put poles and some kind of covering Over the poles? or Do you cover just the trunk? i have lots of burlap. Does it do better in full sun or mostly sun with part shade.

Sorry about the out-of-focus photos ;-( I tried to retake them but fear that only this one, of the magnolia, has come out clear enough. Luckily (if one can call it that) the lesions on both the redbud and magnolia look exactly the same. The damaged section in this photo is about two inches long and there's a smaller one on a skinny twig/limb next to it that you can also sort of see. Both about 5 feet up on my 6+ foot Little Gem.

Ken, the Little Gem was purchased at Home Depot last year and the Forest Pansy came from an independent nursery and both were lugged home in my Subaru Forester. Neither have had any "mechanical" damage that I can think of. When I first noticed the problem, the swollen cracked part felt a little soft and moist but it's since hardened off. And as I mentioned in the original post, there is new growth above the lesions on both trees.

Fingers crossed someone here can enlighten me on what's happening... Thanks.

Looks like mechanical damage to me as well, although it can be hard to judge without being there. There's only two things you can do, prune off the damaged branch or wait it out and hope that it heals over.

This looks like mechanical damage ie rubbing during transport. You may not have done the damage moving these home in your Subaru. This may have happened between the grower and the seller.

This doesn't look like major damage at any rate. The tree seems to be handling and repairing it on it's own. Unless you need to have it perfect I'd leave it be.

Assuming it is some kind of mechanical damage, just leave it be. Magnolias handle the sealing off of an injury fairly well. It will not happen overnight, but in a few years, it will callus over. The process is known as compartmentalization. Animals (including us), 'heal'; plants do NOT heal. They seal off the dead portion and grow over it. Do not apply anything to the wound or even cover it.

Magnolias are a favorite in the annual buck rub due to their soft bark, so I have had this type of damage previously (except more extensively). In fact, when it first happened, I assumed it was something my neighbor did unintentionally. The wound is now completely calloused over with healthy tissue.

as your plant gets established.. and growing to specs... you can remove these things thru selective pruning ...

these injuries occur ... w/o showing ... after some prolonged rubbing incident ... and there is some damage to the tissue under the bark ... that is were the cambian layer of the plant is.. the vascular system of the tree ...

and when its damaged .. that bark above.. dies.. and the wound shows ...

if you want some pruning advice ... give us some pix of the whole plant ....

try to picture this.. some guy.. tooling down the road in his yugo.. with a 12 foot tree sticking out the back ... the trunk rest on the edge of the trunk ... etc ...
