We have a large Gunnera. Oregon is HOT and DRY this year. Water is short. More important to have showers and clean laundry than the usual large gunnera. Some of the older and outside leaves have wilted at times between watering and have damaged areas. Can I remove those leaves ? Thinking the plant will need less water that way. Worried about the open tube of the stalk for pests etc. Any Tips appreciated. Thank you
You can remove the damaged leaves as soon as you notice them. Gunnera is rarely bothered by pests or disease so the open tubes should not be a problem.

Every year I see these huge seed pods growing out of my gunnera plants. I do not use the seeds, so is it necessary to let the plant waste its energy on making seeds, OR can I cut them off to allow more energy go to the leaves ? Thank You
You can trim off any plant's seed pods if you don't want it reseeding or don't want to save the seed.

It had 3 new leaves with stems about half inch diameter.
It could be anything, and unfortunately your photos did not come through. I will be unable to identify the issue. You might need to look for signs of what it is. Slime trails would indicate snails or slugs, which feed at night. Deer or other animals might leave fur or droppings. Once you can figure out or catch in the act the culprit, then you can make a treatment plan.
