Hi All - Question for the pros. I have a DA Vanessa Bell in a container. We're moving and the goal is to get it in the ground at our new home eventually, but it needs to stay in a container for the time being. It overwintered and is leafing out beautifully, but the leaves appear way more lime green/yellow than I feel like they should. I know VB foliage is on the lighter green side, but I'm concerned this may be due to a possible Iron deficiency. Attaching some pictures to show what I mean. Any ideas/tips? I was thinking of possibly adding some Iron Tone to the soil, but I figured let's ask here first! Thank you in advance!
