Although this is something of a dying art these days, there are a few things you can check for in order to conclude what course of action to take with your tree.

Here is a short guide, compiled by the Tree Contractors Directory that should be quite helpful:

Pooling at the base of the tree is a potential sign that the roots aren't absorbing the water properly, which could create issues in the health of the tree. This lack of absorption could be caused by a variety of external factors or even biological factors within the tree; however it is something that should be taken seriously. This is because if the tree is not taking up water then it will become dry of water and be sapped of life. Talking to a professional might be of help if your tree is drying out, who will be able to advise you on the best course of action.

Spring is perhaps one of the more beautiful times of year as you can see glorious blossom, so if you notice your tree has failed to flower, it should suggest something is amiss. Not only could it spoil a scenic garden for the season but it may also indicate that the tree is unhealthy and needs diagnosing. This is because flowering is part of the process for certain species, so if you are expecting blooms yet it refuses to flower then it could need treatment. It is best to treat as soon as you notice a change but treatment doesn't necessarily have to be complicated and you'll have a couple of options; such as adding extra fertiliser or making sure you water it regularly.

Many different animals need the habitat of a tree to live, so it is worth noting whether animals are attracted to the tree as if they are absent that can suggest that there is an imbalance. You can tell this because if animals aren't keen to live there then it isn't offering enough food or shelter, which could disturb the local ecosystem. Summer is the perfect time to take note of any alterations in the trees as it is then that animals start to wake up from hibernation and would be seen in the tree. So if your tree is looking a little bare of animal life, it is time to investigate.

Birds, insects, animals, water and even wind can carry tree fungal spores from place to place. Some tree fungal spores become pathogens when they germinate on wounded areas of trees. This means that if inhaled they can cause some levels of discomfort, especially on the chest and in the lungs. It can also spread to any of the other trees in the garden. Also as it is not always clear what the fungus is, it is advised that you get in touch with a specialist. It could well be that tree pruning experts from TreeContractorsDirectory.co.uk might be well equipped to get rid of the fungus.

If the plants grow around a tree start to wither away then this suggests that the soil is insufficient to meet the needs of the tree. Actually, this might be a sign that the tree isn't getting enough biological support from the soil. This is because if a small plant cannot survive then it means that the conditions aren't right and it won't be long until the tree dies. Fertiliser and extra watering can help if you see this happening to your tree. Make sure you check up on your tree to check that it is making improvements.

By following the guidelines above you should know whether you should chop down your tree or whether an experienced tree surgeon could help.
