I water my conifers regularly but the leaves go brown. Why?
It could be lack of lime, but it could also be either left over damage from winter cold or a lack of sunlight. Do you prune your conifers? If you do, you may have pruned the top too wide. If you do not, they may need to be pruned a bit to allow more sun to the lower branches.
I live in Tasmania's northwest coast and have four conifers, about six feet tall, planted in a line next to one another. I have noticed that some areas are turning brown. This is mainly around the bottom and one has brown appearing on the side. I was told that it may be a lack of lime in the soil. I was also told that this is normal in the summer and I should not do anything. Can you please advise me?
It could be lack of lime, but it could also be either left over damage from winter cold or a lack of sunight. The sunlight is especially true if the tree or shrub is affected on the bottom of the plant. Sunlight does not get down to the lower branches through the upper branches and the lower limbs start to die.

Some of their needles are dropping.
Perlite can help with drainage. If the soil is staying too wet, this could be causing the needle drop. Make sure that there is plenty of drainage holes at the bottom of the pot as well.
We have over 300 conifers in our garden, several different species. We are now in late/mid summer and several of them are showing signs of distress. Whole branches are turning brown and brittle and losing their growth and needles. We have experienced a wet summer. Can excess wetness affect the health of the trees? I surface feed them all fish blood and bone in early spring and again in mid summer. Is it possible to overfeed them, and am I using the right fertilizer or is there a better one available? Thank you so much. I do hope you can help. Regards, Wendy.
Yes, wet summers can affect them by causing fungus or root rot. It may be a fungus on the needles or it can be a root rot of the roots.
Try treating the needles with a fungicide and check the roots for softness and rotting.
If I have conifers felled in my garden and the roots ground up, can I replant the area with new trees straight away?
As long as the trees that had been there were not removed due to disease issues or there are no chemicals in the soil, it should be fine to replant now. This article has more info: https://www.gardeningknowhow.com/plant-problems/environmental/planting-in-old-spaces.htm
I had a few huge and tall conifer trees chopped down last June. Only the trunks are left now. Will they grow again? And how long will that take? A lot of the bark from the tree trunk is peeling off and can see the inner layer, but I cannot see any green. Please advise what I should do to them. Thank you!
Unlike many deciduous trees and shrubs, most conifers will not resprout if cut all the way back to the base. Typically, pruning of conifers is only done as a last resort because of this and then it's only trimming for shape or to remove dead/diseased growth.
I have just dug up a conifer tree, about 2 metres tall. I tried to dig around the roots as much as possible. The roots are now about 65 cm in length roughly. Can I now plant this tree in a pot? If so, how big does the pot need to be? I have a 66 cm round pot. Shall I leave the roots as they are or shall I snip them back? Will this tree survive?Any help would be appreciated.
You can probably root prune some (so it fits comfortably), but I wouldn't take too much off. Also, the pot needs to be at least 2 inches larger than the rootball, though I would go slightly larger than this if you do not want to repot anytime soon.
