Please help. I believe I have an angustifolia agave. I added a pic of the first day I got it, one week ago, and now the bottom leaves are turning yellow and black and the leaves look dry. There appear to be 2 pups underneath, plant is 3' wide 2' tall, pot is 17" wide 12" tall. I live in Wisconsin and keep it in full sun and bring it in if it gets to low 40s. I was watering when soil was dry but have stopped since we've had rain the last two days. Please let me know if there's any more info or photos you need, I really want to save this plant. Leaves are mainly black on the ends of leaves and I do not see any insects.  |

| Please post a photo of the entire plant as it looks now. It is difficult to diagnose plant problems just from their symptoms. I assume your Agave was inside for most of the winter. Where was located relative to the nearest window? What was your watering routine during the winter?

I did not have it during the winter. Above on the original post I have included a before and after (current) pic of the plant.  |

| I would like to see a "now" photo of the entire plant so I can assess its overall condition and deterioration since you purchased it. It is hard to imagine what you could have done in such a short time, so it begs the question as to how well it was cared for at the greenhouse. Exposure to temps close to 40 degrees after it has been in a warm greenhouse all winter might explain it. Also, what are your plans for it when cold winter temps return?

| Thanks for the photos. I don't see any major damage at this point. It is normal for plants to suffer some minor deterioration of older, lower leaves when they are relocated. The closer you can match the temperature, light, and water that it received in the greenhouse, the better it will fare in making an adjustment. Trim off the discolored leaf portions as they occur. Initially, you may want to keep it in light shade when outdoors and protect it from temps below 50 degrees. Assessing water is difficult with Agaves because it is so hard to get past the sharp leaves to probe the soil with your fingers. Rainfall complicates it. In general, it is a succulent and tolerates drought quite well, but does not like constantly damp soil. The soil should dry deep into the pot before it gest water. Err on the side of dryness with this plant When moved inside in the fall, it will be forced to make another significant adjustment as the light indoors is greatly reduced, even when supplemented with a grow light. Place it directly in front of and close to your sunniest window. Reduce your watering as it will use very little water in winter.

   It looks to be getting worse... any suggestions? I have brought it inside now, sitting by a window, there do appear to be spiderwebs on it and I've seen a small bug/spider. Can I spray with water and gentle dish soap? |

| Those are symptoms of a light or watering issue. Plants react slowly to changes in their environment. I suggest you settle on a permanent location for your Agave so it has lots of time to adapt. Be patient. Focus on the health of new leaves, not on the discoloration on the older leaves. Agaves are not favored by spider mites, so I don't think that is what you have. The webs may be from garden-variety daddy longlegs. No need to spray.
