Unhealthy Crape Myrtle

6 years ago

Hi,

We have a Crape Myrtle Natchez tree. It was planted last year (zip code 27519) in July by the builder’s landscaper. Since then during the growing season, it gets water from rain. When it doesn’t rain, it gets water two times a week from a sprinkler hose which goes through the gap in its trunks and through our yard. The sprinkler hose is really for the grass. Since last year was the first year, we would also fill a gator bag once a week at least as recommended by the builder. Not doing it this year.

The leaves came this year, but generally speaking the tree doesn’t look healthy. The leaves have an orangish brown color. Some leaves have been skeletonized. When I looked at it closer a couple of days back, it had a Japanese beetle and a Mexican bean beetle. I sprayed it with Sevin Insect killer and don’t see the bugs anymore. There is no sign of a large infestation. I also applied a slow release 16-4-8 fertilizer a week back which I realize how was not applied correctly because I simply spread it around the trunk. Our grass gets fertilizer about every 6 weeks through an annual maintenance program. I don’t think I saw new buds on the tree. The ones on the tree appear to be on dead twigs and the buds themselves are dry and dead. There are three plants at the bottom of the tree. From online search, they appear to be hillside creepers. Two of them were in bad shape last year and looked like they were dead, but they came back although still not quite full yet. The location of the tree should allow it to get sun for more than hours. The drainage is also good in that there is no standing water nearby. There may be some immediately after a storm, but it drains off not very long after. The tree is about 10 feet tall and the soil is clayey.

I am wondering what I should do to restore the health of the tree this season. The leaves of the tree are not deep green and full as of several of my neighbors’. Also, I think it should already be flowering now. When I drive in my town, the crape myrtles are flowering everywhere. Although the curious thing is I haven’t seen any of my neighbors’ tree flowering, except one. Not sure if that has to do with the age of the tree.

Any help will be appreciated.

    lawn irrigation is usually not good enough for tress or shubs.. you need to water down theu the root mass planted ...


    take a hand trowel or tablespoon .. and dig a bunch of holes around the gob planted.. and native soil .. AND FIND OUT ABOUT MOISTURE at depth ... water accordingly ...


    you really shouldnt hav sprayed for one or two bugs.. next time just pic them off ...


    big city name.. would have helped as compared to zip code.. i wasted about 3 seconds of my life looking that up .. lol .. NC huh???


    it was a HUGE transplant ... it can take two or three years to get over the stress of that ... and during that time .. all you do is water properly .. deeply with near drying before the next ... i would go as far as getting the lawn irrigation off it completely ... not may shrubs like wet foliage .. especially at night ... which is when such irrigation usually runs ...


    its stressed.. not hungry ... no more fert .. maybe ever ... its a shrub..not a child.. it doesnt need to be fed.. nor educated.. etc .. treat it as one ...


    and as with children.. dont compare yours to the neighbors ... lol ... yours just had more stress than the neighbors .. in a year or 3.. you probably wont be able to tell the difference ...


    i dont know about that scarred trunk or whatever ... if there are leaves above.. the trunk is still viable.. if those leaves die.. we will cut it out ...


    i dont understand what hillside creeper is.. nor why it is at the bottom of your plant ...


    drainage has little to do with puddling water .. its more about how water moves thru your soil.. and away from the plants that dont need it ... a perk test might help you understand how your soil works ... most plants want a drink of water.. and all the rest to go away ... in clay soils.. sometimes that doesnt happen.. and your plant end up standing in water you cant see underground.. yours doesnt look like that .. imo ...


    and lastly ... these are not annuals or perennials ... we talk of tree or shrub time .. on some level .. your expectations are a bit high for the large transplant ... in a year or 3.. it will probably please you ... but it isnt going to happen this year .. so try to relax.. water it properly ... and if you see any other singular bugs.. just squish or remove them ...

    do a perk test .. maybe a couple .. and report back any extreme results ... we are basically looking for bad clay below whatever the builder heaped on top ...

    I’m not a pro, but have grown many, many CMs for over 25 yrs at various houses (Tx). And there’s one thing I’ve learned most: they’re picky and temperamental until very established.

    Can you get a closer picture of the planting area/bottom of Crape? It could be planted too deep and root flare needs to be uncovered.

    As mentioned, Crapes sometimes don’t thrive the first couple of years ... then just take off.

    One of mine struggled badly the past two years. I realized it had sunk in my clay soil, and I GENTLY dug the root flare out a month ago, mainly with gloved hands. You can research doing that. I watched several videos and How-Tos before proceeding.

    Mine is thriving now, very happy. Lots of blooms coming any day now. Leaves look healthy. :)

    @ken_adrian - thanks for taking the time to write an extensive response and for your expertise. I will do a perk test. It’s forecast to rain here the next few days, but hopefully the weather will clear up after that enough for me to do this test.

    @Jinx - thank you. I checked this. When I removed a small amount of dirt from the base of the plant, I could see and feel the roots. So, I think this should not be a problem.
