Hi there,
I've had 2 different young plants die in one particular spot over the last 2 months. The location is where we had a small oak tree which we had taken down 2 months ago. It was not sick but due to its location near our house it was recommended be removed before it grew bigger. I can't remember the exact spot but it is around the area where these plants (Nepeta Tuberosa catmint and another pink flowering plant of which I don't recall the name) keep dying after a few weeks before they get to establish their roots. Now the 3rd plant (Coleonema pulchelleum Sunset Gold) is also starting to show a sign of yellowing. It's puzzling because all my other plants around that spot and across the garden are thriving.
When the second plant died, I inspected the soil which was dry, and many ants were coming and going from the spot. My initial thought was that the soil was not kept moist enough and that the ants started to make their nest or passages, creating air tunnels that eventually dried up the roots. So before I planted the 3rd plant, I made sure that the irrigation system is set at the right watering frequency and that the ants were mitigated. Now when I saw the yellowing of my Sunset Gold, I dug the plant out to see the roots and the soil. Looks all good and the soil is moist but ants came back very active. I dug further and saw there was a remaining root from the oak tree. Mind you, the oak tree's stem was completely removed and separated from the roots, so the roots are not alive.
Could it be possible that these roots are the cause for the ants (maybe pests reside there?) Any insights or advice is much appreciated!
PS- we live on the coast in Norther California (zone 10a). The garden location is SW, and the spot in question is in shade until about 1pm, thereafter full sun for about 6 hours.
