I think it does make sense to dig it up and inspect both the roots and the planting hole. It might be that the soil in that particular place does not drain as well - or drains too well - and doesn't keep enough moisture in the soil for healthy root growth. When you replant, roughen up the sides and the bottom of the planting hole and if the soil is clayey you can mix some organic matter into the native soil and backfill with the newly amended soil. Normally we don't recommend amending the planting hole but it sounds as though the roots of your crape myrtle are struggling and might benefit from this extra rich soil. Be sure to replant it at the same soil level as it was growing before and water it in well to help settle the soil. Hope this does the trick~ |
