Stump Grinding

Stump Grinding

Stump grinding is only able to be completed after a tree has been removed, leaving a tree stump. Stump grinding is when a machine, called a stump grinder, is used to remove the remaining stump which is completed by the machine using a rotating disk which gradually chips away at the stump, creating a smooth surface or ground, leaving none of the stump behind. Stump grinders can range in size and shape from as big as a lawn mower to the size of a truck. There are various advantages surrounding stump grinding and its effectiveness like it’s fast, great for the garden, excellent for the environment and has minimal damage effects.

Stump grinding can prove to be one of the more effective methods of removing a tree stump. Using a stump grinder is one of the fastest methods of removing a tree stump. The reason behind this is due to its powerful spinning disks which constantly chip away at the stump. Tree stump grinders eliminate many of the hassles associated with traditional methods of stump removal like having to clear the roots away and digging around the stump. All these issues are eradicated effectively with the job being completed in a shorter period of time using a stump grinder.
Not only does using a stump grinder decrease the labour involved with removing a stump, but it is also excellent for the garden. Stump grinders prove to be excellent for the garden as their disks carve through the stump, creating nutritious mulch for your garden. Not only is it a great source of mulch for your garden, but it looks fantastic on your garden bed.

Stump grinding has had increasing popularity with environmental preservation groups. The reason surrounding this is due to the use of stump grinding in the removal of disease infected stumps. Removing these stumps will permanently prevent the further spread of these diseases between other trees, meaning stump grinding is the perfect tool for the job.

Another benefit surrounding stump grinding is the minimal damage it produces when in use. The reason for there being minimal damage is due to the accuracy of the machine. The accuracy of these machines are precise and remove the stumps without damaging its surroundings which can include other trees, plants or landscaping.
Stump grinding is the best method of tree removal.

Stump grinding is completed in a much quicker time than traditional methods, provides better results, is great for the garden and is beneficial to the environment. For a free quote, talk to Sydney Tree Removals.

Removing Tree Stumps with Salt

Comments Off on Removing Tree Stumps with Salt

After a tree is cut down it may take many years for the roots and trucks to die. Often stumps will go on living for many years to come with new roots developed and sprouts not only appearing at the stump but in the tree’s general area. If stump removal and stump grinding is not an option for you (although they are relatively inexpensive) and you don’t feel the need to burn the stumps or use toxic chemicals, then the use of rock salts might just be for you!

How it is done

  1. Have the tree lopped to as close to ground level as possible. Make sure it is safe and not a tripping hazard.
  2. Drill holes into the side of the stump at a downward angle as close to the top of the stump as you can. Make sure the holes you drill are at least 2 cm in diameter.
  3. Drill additional holes all around the stump. The larger the stump – the more holes it will have.
  4. Fill the holes with rock salt. Compress the rock salt in using a rod.
  5. (Optional) If you are not concerned about nearby vegetation sprinkle salt around the base of the stump.
  6. Cover the stump and salt with soil. Give it a good soak with water so the salt dissolves and enters the soil.
  7. Water the stump every 2-3 days for 5-6 weeks. This helps the salt enter the stump.
  8. If you notice any growth during this period repeat the salting process. Patience is the key to success!

If you’d like the stump to rot faster now that it’s dead, have a read of this organic stump removal process.

Organic Stump Removal

Comments Off on Organic Stump Removal

Removing stumps can be a long, difficult, and exhausting task. There are many methods from digging it out, using toxic chemical, to stump grinding. Somewhere in this spectrum of tree stump removal methods there is removing the stump organically. That is, removing the stump using natural products, methods and allowing Mother Nature to do all the hard work. This article focuses on using mushrooms to speed up the process of decomposition. There are plenty of other organic stump removal methods, this is just one.

Before I begin – organic stump removal isn’t for everyone. It should be used for people who don’t require the stump removed immediately, have limited funds or have an organic philosophy to life.

Stumps are massive. They take several years to decompose unaided. So if that stump is going to be around you might want to make the most of it and get some edible mushrooms out of it… right? Tasty gourmet mushrooms are natural stump removers. They break down the stump while producing a wonderful supply for your gourmet dinners. Mushrooms can halve the time it takes for a stump to be fully decomposed.
Before you start a word of caution – you need to be able to identify the difference between poisonous and edible mushrooms. Just because you plant edible mushrooms doesn’t mean that a poisonous species hasn’t beat you there and has started growing first. You need to be able to correctly identify the mushroom you intend to eat, mistakes can be fatal.

You’ll need to pick a suitable mushroom for the job. Mushrooms like shiitake and oyster grow very well on logs but are not suited for growing on stumps. Stumps are a highly competitive environment and you need to use a mushroom variety that can handle competition. There are some mushrooms that are stump specialists so you may want to consider these; agrocybe aegerite (black popular mushroom), hypholoma sublateritium (brick top mushroom), grifola frondosa (maitake), laetiporus sulphureus (chicken-of-the-woods mushroom), trametes versicolour (turkey tail mushroom). I will leave it to you to do your research and decide what is best suited for your environment and taste buds.

The method is actually quite simple. You need to inoculate the stump with mushroom plug spawn. This is a small wooden down that has the particular mushroom that you were looking to grow on it. Drill a hole in the log or root and then hammer that dowel in, making sure to seal the hole with wax upon completion. Obviously, the more plugs you put in the better. You can space them at around 2-3 centimeters apart. If you don’t have access to a plug spawn you could alternatively use sawdust spawn in the holes. It is harder to protect, but well worth the effort.

Benefits of Stump Grinding

Comments Off on Benefits of Stump Grinding

Stump grinding is possibly the most effective method of removing the remnants of a tree stump from a garden, plot or landscape. By default arborists only remove the tree to the ground level.

Usually, a tree is lopped to the lowest possible point that cutting equipment can operate at without being damaged by being run into the dirt or concrete. This means that a small section of the tree truck may stick up from the ground. These stumps can be unsightly and a tripping hazard. They are also subject to disease which may run the risk of spreading into nearby plants and trees in the nearby area.

Stump grinding allows for a complete removal of stumps that not only eliminates potential hazards, but also creates an opportunity for new plants and garden beds.

Having being experienced with many years of stump grinding, we know that our stump removal service offers several benefits:

  • Affordable (and cost effective)
  • Clearance means that construction of pathways, patios, fencing or walls can be built without obstruction
  • Any size and any amount of stumps can be removed quickly and efficiently
  • Stump removal is fast and has minimal disturbance
  • Minimal risk to damaging surrounding areas
  • Fully licensed, insured and certified service

Removing a Tree Stump with a Tractor

Comments Off on Removing a Tree Stump with a Tractor

This is an interesting video that shows how to remove a tree stump using a tractor. Well, they use an excavator attachment on the tractor but that is besides the point. If you have the heavy machinery and the space to dig out a stump mechanically it is a great option. It is a more thorough alternative to stump grinding which is the more common approach, however, if you have to hire the equipment it becomes very expensive quickly. The video shows  how large the root ball of the stump is and how easily the tractor can dispose of the stump.

Poisoning a tree stump

Poisoning a tree stump*

After a tree is removed, often the stump will continues to grow and there will be sprouts of growth on the stump in the few weeks after it is lopped. If left untreated then the stump could potentially regrow into another near full sized and slightly disfigured tree. Removing the tree stump is the only way to prevent the tree stump from regrowing if poisoning and kill the stump is an unacceptable option.
The first thing that needs to be done is the tree must be cut to ground level, or the lowest level permitted by the terrain. Within 30 seconds of causing an injury to the stump or its roots a generous application of tree poison needs to be applied. Any delay in applying the poison may allow the tree’s cells to close up and the stump won’t accept the poison as readily. Use a chainsaw to cut grooves in the stump and roots and quickly apply the poison using an applicator or spray bottle. Drilling holes into the tree’s stump and roots is an equally effective option.

There are many products on the market that would be suitable to poison a tree stump. Glyphosate based liquid poisons are highly effective (such as Round-up, glypho 450, zero, etc) when applied in this manner. Make sure they are applied in dilute form and in accordance with the manufacturer’s instructions. Wait around 6 weeks and then reapply in the same manner – making grooves in the timber before a quick application. If the poison is undiluted it will damage the cell membranes of the stump but not be absorbed by the plant which how they cause the stumps to die.

A common concern with glyphosate based poison is that it is considered a nasty toxic herbicide. In fact, it is one of the least toxic herbicides and it is not soil residual. This means that in 14 days from application it would be impossible to detect in the soil as it leaves without a trace. There is zero chance that glyphosate would poison plants that it was not applied to. So don’t get over zealous with your application and accidently exposed the other plants when you were applying it. There is the risk if it rained within 6 hours of application the poison could spread – so check the weather before applying. Also, in winter trees can have greater resistance to herbicides as the tree’s growth slows during this time.

For stumps that just refuse to die there are some serious heavy duty poisons available. Tordon has an injection poison, which is injected into tree stumps roots and causes rapid death. Graslan and Tordon have pellets which require drilling into the tree stump and inserting the pellets that get slowly absorbed. There are basal bark forms from Access, Garlon 600, and Starane which are also highly effective for those hard to kill stumps. We suggest using a glyphosate poison, but if it isn’t working then try the cut stump method with any product from Access, Garlon 600, Tardon, and Starane – they are guaranteed to do the trick.

If you can’t be bothered with poisoning your stump you could always get a professional arborist to come around and poison or remove the stump for you. Try the crew at Sydney Tree Removals as they are highly affordable and have an excellent reputation.

*The drill holes in the picture are incorrect, the ideal place to drill is just into the cambium layer which is just inside the bark.

How to Remove Palm Tree Stumps

Palm Tree Removal

Root ball of a Palm Tree

There are many varieties of palm species and they have one thing in common – they have a long fibrous root system that has evolved to withstand  tropical cyclones. These roots go deep into the ground and spread a distance around the palm tree. They can be responsible for movement in building’s walls, retaining walls, pavers, concrete, sewers, or other nearby structures.

Removing Palm Tree Stump

Root Structure of a Palm Tree

You only have two feasible options for removing a palm tree stump – using an  excavator, or hiring a stump grinder to remove the stump to below ground level. As you can see from the pictures of the palm tree stumps it would take a long time to dig up and cut through all those roots. We have spoken with people who said it took them years to remove palm tree stumps even though they worked on it a  few hours every weekend till it was gone. They vowed never to do it again.

Using an excavator

In this method you use an excavator to dig a huge hole around the stump so you have access to the palm tree’s root ball. You cut off any long running roots and lift the stump and root ball out of the ground and transport it to the tip. This method is best if you need the entire stump removed if you are already planning to build a structure there or requiring to plant another large mature tree. If you plan to use this method, ensure it forms part of your construction plan (if building a house), since an excavator & truck adds up quickly. Depending on the size of the excavator it can be around $80 per hour, with additional costs for hiring truck hire to dump the stump, paying the tip to take your stump, and then all the additional time to restore the site.

Hint: You must dial before you dig to check for buried services. Their could be telecommunication, water, gas, or electrical lines where you want to dig!

Stump Grinding

With stump grinding a machine is used that has rotating discs with teeth on them that are used to literally grind the stump away. It operates in a fashion similar to a chainsaw – reducing the area being grinded to sawdust. The grinder can only remove what it can reach – which is usually only 1-2 feet below ground level. This method is usually cheaper than  excavating, with a typical stump grinder costing around $100 per hour (with operator) but the work will be carried out in less time (around 3-4 hours). This option is the better value for money choice, but you still have the stump rotting away below ground level. You can plant a garden on top, but you will have to wait a while if you want to plant something that requires deep root penetration.

Stump Removal Options

When it comes to stump removal, there are a few approaches than can be taken. There are so many myths and “simple solutions” that complicated the process because so many don’t actually work. The following is a list of common ways to remove stumps. This is based from experience in the arbour industry and should help prevent you wasting your time.

Chemical Removers
There are a few chemical remover products on the market, most of them are high in potassium nitrate. The product is spread on the stump and it is used to accelerate the decomposition of the stump. There is no product on the market that makes the stump disappear appear in weeks. This process will take months provided you follow the instructions – keeping the stump moist and covered – or it will even take years if it is a palm stump. Another cheaper option is to use a manure that is high in potassium nitrate like cow manure. This will achieve the same results as a chemical product. First drill holes into the stump, fill it with the manure, and then keep moist and covered. It will decompose as fast as nature will allow it. That is, unless you give it a helping hand by burning it – which brings us to the next stump removal method.

This is a common method of stump removal but is highly ineffective. It is rare for a stump to stay on fire since it sits deep in the ground and no enough oxygen is supplied to the fire. However, stump burning can work after the treatment of a chemical remover since it causes the stump to be more porus (allowing more oxygen in) and the potassium nitrate will provide fuel for the fire (so to speak). It still comes with a big risk: if you burn a stump you could end up with charcoal material that decomposes even slower than the stump, and is even more difficult to remove. So DON’T DO IT.

BUT… If you still have your heart set on burning that stump out of the ground there are a few things you can consider. (Your neighbours should definitely be a consideration!) But in addition to using a chemical additive to make the stump more porous before burning, you can build a makeshift open stove out of a large metal can or bucket, placing the stove over a portion of the stump and let it burn for a time. After you are satisfied that the area of stump has been burnt out, you should then move it to another area on the stump until the whole stump is removed. Make sure to remove any charcoal from the stump after each fire. If done right, this method can be an effective way to remove a stump. But generally, it should only be carried out in rural areas such as farms. In the suburbs or the city this is a big no no.

We wish there was small caterpillars we could use to remove stumps for us, but grubbing is actually the industry term for manual labour. Getting those gardening gloves out of the shed, grab your crow bar, mattock, shovel, chain saw, and dig the heck out of that stump. When you grub, you need to first dig a trench around the stump to as deep as you can go. From this you need to work in under the stump cutting off the roots and freeing the stump for removal. This can be really hard work and not a job for those with sensitive backs. If you stick at it long enough you will eventually get there.

Stump Grinders
Decomposition and grubbing can be used to get rid of stumps. However, some clever engineer was contracted by an arborists to make his job easier and came up with a stump grinder. This tools are machines who use rotating teeth to grind away a stump to below the ground level. This doesn’t get rid of all the running roots, but it does get it low enough that you can plant a flow garden, or cover it in dirt so natural decay can occur out of sight. Stump grinders can be hired, but it is recommended that you should hire an experienced arborist or landscaper to do this work because it can be very dangerous. Grinding a stump can take an hour or two, but setup and removal might add another two hours onto it. This still isn’t easy work and required a bit of elbow grease, but it is definitely the best option for stump removal.

If you’re looking to remove stumps from your property, consider talking to our favourite stump removal experts who can arrange a professional to remove that stump for you in no time and at a fair and reasonable price. If you end up doing it yourself, just be careful, it can be a dangerous task.

Stump Removal

Comments Off on Stump Removal

Not all stumps can be removed using a stump grinder. Professional arborists have a few tricks up their sleeves for removing difficult tree stumps.

Leveraged removal: Depending on the circumstances. This method requires manual or mechanical digging around the base of the stump, detaching any roots that might be problematic, and then applying appropriate leverage through a chain block system to pull the stump out of the ground.

Manual removal: This is the hardest way to remove a tree stump, by digging it out manually. This sometimes is the only option if the stump is located in a hazardous or confined location.

Chemical removal: This method requires a chemical stump removal product to be applied onto the stump to promote the decay of the stump. Stump removers are normally made of potassium nitrate (KNO3) and take between 4-6 weeks to make the stump rotten enough for it to be removed in fragmented pieces. The limitations of this method are the use of chemicals and it lacks immediate results. Sometimes people set stumps on fire after chemical treatment to speed up the removal process because the potassium nitrated once absorbed acts as an oxidizer, but we do not encourage this method as it is dangerous, and stump grinding is a fair superior, safer, and quicker option.
