In my garden area I found some curry leaf plants growing by themselves. Even they have a root network spreaded all over the area and every where small plants are growing. These thing are not letting me do seeding and other gardening activity for other plants. I am feddup with this self growing curry plant and want to get rid of it. They have nearly 1or 2 inch thick horizontal roots spreaded all over the garden at depth of 3 to 5 inch.
If you treat with a herbicide it can kill the tree that these suckers are growing from, a concern if this is your tree!
You can prune them off, near ground level and pour boiling water over the wound. This reduces sucker regrowth without killing the plant. The only drawback is that this should be done every month.
I just removed and replanted a curry leaf plant about 170 cm tall, worried the roots could have been damaged , as i would like to save the plant , After 2 Weeks of relocation now i can see the leaves are falling and the plant looks dull, The place i planted doesnt get a lot of sunlight only in noon and evening it gets decent sunlight, I dont know if they are shedding due to lack of sunlight or just the shock but need advise on this
These are quite sensitive to transplant. It is likely that this is just a simple case of transplant shock.
There are many things that will reduce transplant shock from many different brands. A google search will give you many different choices for supplements that will help here.

My curry leaf tree looks unhealthy and the stem or bark is discolored as seen in the photo. Also the leaves are a pale yellow in color which is not normal. I would like to restore the plant to its healthy state and need to know what to do about it. The plant is outdoors and receives quite a bit of sunlight. I live in the Melbourne - Australia. Please advise.
What is your watering schedule? Too much water can result in yellow leaves and black stems. Try cutting back on the water. It also wouldn't hurt to get a soil sample to check for a nutrient deficiency.

I live in Bali and have a curry leaf tree growing in my garden that sends out prolific underground shoots that are difficult to remove. How can I stem the tide of these unwanted interlopers?
Yes the root suckers are a common problem. One way to limit the spread is to dig a trench and install a "root barrier".
But you can't do that too close to the tree or you will cut too much of the root system.
Closer to the tree you are limited to cutting the suckers down to soil grade periodically.
Do not use an herbicide to poison them or you could kill the parent tree.

My CP is around 6 months old and doing well. I know not to water, keep warm etc. The pot is small with not much compost, and the top of the compost has gone white/ mold. What should I do, and if I need to top up the compost what should I use? Many thanks
You can lightly turn under the moldy top layer and top it off with compost.

I have this tree growing in a pot indoors for over 2 years. It does get a lot of sunlight even in winter. I have suddenly noticed that there is no fragrance when I touch the leaves and when I cook with them. Why?
It likely needs more light and fertilizer! These are notoriously heavy feeders and light hungry. This article will help you with their requirements: https://www.gardeningknowhow.com/edible/herbs/curry/growing-curry-leaf.htm
