I have an indoor elephant ear plant which has been thriving inside for 6.5 years. The problem is with the ongoing loss of leaves. The stalk has become way too long, making the plant top-heavy and unstable. How do I remedy this situation in the easiest and best manner?
Loss of leaves from a houseplant could be due to overwatering, underwatering, pest problems, light problems, or changes in the environment like the indoor temperature:

If a plant is not getting enough light, it may become "leggy" and top-heavy as it grows too tall in an attempt to find a light source. Increasing the amount of light your plant receives (from grow lights or sunnier windows) could help it produce more healthy leaves. After a few leaves have grown, you can prune back the tall stem.
We have a VERY large and tall elephant ear plant that is almost like a tree (with a trunk -- no pun intended:-) The plant is outdoors and in the ground. We live in South Texas and have had an unusual hard freeze which, not surprisingly, took the leaves. The wet, heavy leaves caused the "trunk" to be almost horizontal. We have removed the dead leaves and propped up the "trunk" for the short term, but I am wondering if we can shorten the trunk? If we saw off part of the trunk, will it kill the plant, or will it come back from the shortened trunk? If it is ok to shorten the trunk, how much of it can we remove? Thanks! Donna.
Elephant ear plants can be pruned back to the ground, and they will grow back from the tuber. You can cut the trunk back as much as you wish. Since it's winter now and the plant has already frozen, this treatment won't hurt the plant.
I have a giant Thai elephant plant. It was covered with blossoms all last summer. I want to know if the seeds started from the flowers will be true to the species... Will they all be Thai giant elephant ear plants? Or do they have to be started from tissue to be true?
Growing from seed is not very successful.
It is best to grow from off shoots.

I have a huge plant, and for the first time, the tubers are coming out of pot and have reached a good 3-4 feet long, along the floor. Do I leave it like that? I had it outside this past summer. Looks great, but the tubers?
Sounds like it's time to divide your plant!

My elephant never gets more than 2 leaves on it. One leaf dries up and dies and another one starts growing. Then the other leaf dries up and dies and another one starts growing and it keeps doing this. It is not getting any bigger. What am I doing wrong?

Is it true that elephant ears will cause ground moles to leave? If so, do they have to be planted in ground or can they be planted in planter and set in yard? And are elephant ears poisonous to dogs?
Yes, Elephant Ears are listed toxic to dogs and all pets.
I found no evidence or research showing a link of this plant deterring moles or rodents.

I have my elephant ears in a container. I want to know if I can plant garlic with them. The container is large.
Yes, it should be possible to plant both in the same container. Just make sure the elephant ear leaves won't shade the garlic too much- if they are too crowded, you may have to remove a few leaves to allow the garlic to get light.
