A landscaper swears by driving a copper nail into the stump of large amur honeysuckle bushes to kill the roots. I'm having trouble finding reliable information to verify or debunk this. Is this an effective alternative to herbicide?

Hello! I saw an idea online for making a raised container garden out of a metal file cabinet by removing the drawers and turning it on it’s back. My question is whether or not it would be safe to eat veggies grown in such a container. One suggestion was to paint it inside and out with non-toxic paint. Another was to put plastic containers inside, and plant in the containers. Wondering about the safest method. Thanks!

Majesty palm smells like dog urine

So I finally figured out where the dog urine smell was coming from. It's my majesty palm. When I put my nose down by the dirt it smells like urine. I seem to notice the odor a day or 2 after I've watered it than I do prior to watering. Recently the palm on the right side died. Now I'm just left with the stub, which I haven't removed yet because I'm afraid the plant will die if I try to transplant it. Any idea why it smells like dog urine?

I have many house plants, palms, dracenas, lilies, asparagus ferns, rubber trees, aloes. Can any or some of these be moved from their wintering indoors to direct sunlight and if so, do they need to be slowly acclimated to it?

Miss kim flowering lilac tree sickness

I have had my Miss Kim lilac tree for around 10 yrs now and a couple years ago it began to lean over then l noticed the bark was splitting on the trunk and last year the branches on one side of the tree died but the other side seemed to be ok. But the tree has leaned way over. It is planted in a garden with other plants and they are doing fine. What is wrong with it. I am planning on getting another one but I don't want it if it will do the same thing.

I am curious about your views of using treated lumber for a raised bed. My research shows that current treated lumber is safe for edible beds and that the copper that is used is actually locked in the soil if it leeches into it. Just wondering your thoughts, or research. Thanks!

Air plant

Hi! What is causing some of these leaves to brown? I spray the plant every other week and let it fully dry out. Is it dying? How do I prevent it from continuing?

Adromischus cristatus

Hello, do I need to replant this so the new the new growth will get bigger? The bigger leaves on the bottom are old..from when I bought the plant over a year ago and much bigger. Some fell off and I got a lot of new leaves. I’m not sure if being in a smaller pot doesn’t allow the new leaves to grow. It’s currently in a 4 inch pot. Thank you.
