We planted four knock out rose bushes in full sun about two week ago. I have noticed that some of the aves are turning yellow. Am I watering too much or not enough? It's very hot here in GA.
Knock Out Rose Bush
Were these in a protected area when they were for sale? If they received very filtered light or were under cover, they are probably having trouble adjusting to full sun (I assume that is where they are planted). I think when it is this hot, it is hard to overwater them. Stick your finger down in the soil to test - it should be moist but not soggy.
