I have a small rosemary plant, but half of it died back during the summer, so I pruned back the dead bits and it seems to still be alive. Apart from that there are some small brown lumps coming out of the stalks. Don't know if this is normal, as it looks like the lumps are breaking through the stalks.
These may be just buds that will develop into new branches. This would be normal. Try to gently wipe them away. If they do not wipe away, then this is what they are.
If they do wipe away, then it might be scale. This article will help you with this problem.

I planted a rosemary in a pot with palm soil so it drains and put it on the south side of the house where it will get sun. But it gets very hot out here in the summer, so will it burn? I live in Southern California and the summer weather can get into the 100's.
They can take the heat provided they get enough water. In a container, in those kinds of temps, it will be very hard to keep them with enough water. You may need to water 2-3 times a day if temps get over 90F.
If you feel that you may be able to keep the plant watered, then it is fine there. But if you will not be able to do that level of water, I would look for somewhere less directly in the sun.
I have planted a hedge of Rosemary that is not very good. The plant leaves are turning yellow. Is it the soil or the plants? We have had a lot of rain recently, also I have put pine mulch on the plants which I fear may not have helped. Thank you.
If the soil is not draining well, then the rain is causing the problem. Rosemary needs well draining soil to grow well. If the soil is well draining, it could be that the plants are in shock (if you planted them in the past few weeks).

A friend recently gave me a beautiful indoor rosemary plant as a Christmas present. I have placed the plant near a south facing window about 10-12 feet away from the front door to my house. Today I noticed that the side of the plant facing the window is dry and grayish brown. The other side of the plant is green. Obviously, the plant is stressed, but I'm unsure what might be causing the drying and browning on that side of plant. I am open to your suggestions on how to save the plant. I live in Oakville, ON, Canada. Thanks so much for looking into this matter for me.
It sounds like it may have a fungus, like powdery mildew, affecting the plant. This can be made worse by stress to the plant. Treat it with a fungicide and this article will help you with caring for it indoors: https://www.gardeningknowhow.com/edible/herbs/rosemary/grow-rosemary-indoors.htm
My son brought a Rosemary (Christmas tree pruned) plant from Texas to Nebraska in November. I watered it as instructed and sat it outside in the day when possible, bringing it in at night without fail. I didn't water it until it was dry within 2" from the top. It started turning brown, so I bought a Sunlight Lamp for when it couldn't be outside. Now it is all brown. Is it hopeless? My situation: If it is, I need to get another similar plant in here and murder my husband before July when our son will return.
It may not be dead, but will need ALOT of TLC to come back to its former glory. This article will tell you how to tell if it is a lost cause and what to do if it is not:

I would also recommend that you not move it back and forth from inside to outside. This can be pretty stressful on a plant, especially in the winter.
Best of luck and maybe you should just beat your husband instead of murdering him. ;)
When I have purchased my rosemary plants even from nurseries, within a couple days they turn brown. I have check the roots and made sure of the water requirements and getting sun when I have planted indoors. What can be happening and can the plants still survive? I trim them back as one nursery told me. Also, when growing outdoors they turn brown. I live in Forestdale, Alabama - part of Birmingham zone 7.
If they are bought from different nurseries, I would guess that the issue is likely watering. While you may think you are giving the plant the right amount of water, the water may not be reaching the roots. If you are allowing the rootball to dry out completely before watering, the soil can actually start to repel the water, which prevents it from getting to the roots.
Never allow the rootball to go completely dry. If this does happen by accident, soak the plant's container completely submerged in water for about 10 minutes to force it to take water in again.
I bought two small rosemary trees for Christmas; however, they are both drying out and almost all the branches are dry. How can I save the trees and propagate them again? Thank you for your advice.
