Gardening, How To, Liam, Planting, Trees

Planting a tree is a decision made with many, many years in mind. With that being said it is essential to give your young tree the best possible start so it can grow to its full potential. With this guide we will show you how to plant a containerised tree.

 

A benefit you get with a containerised plant over a bare root one is that you can plant it at any point in the year. As long as your soil isn’t frozen or waterlogged your plant should be able to establish itself regardless of the season.

1. Before taking the tree out of its pot give it a good water. If you are planting the tree during spring or summer then it is essential to make sure it is well watered as the tree is yet to establish itself fully.

2. When picking a site for your tree, ideally you will want somewhere which is going to receive full sunlight and will be sheltered from harsh, drying winds. Make sure you pick a spot where the roots will have a chance to grow and spread out. If training against a wall then leave at least 1ft of space from the base of the plant.

3. Dig a hole with a diameter roughly 3x the size of the root ball and with the same depth. If planted too deep the lower trunk of the tree may become susceptible to disease; the graft-point should be just above the ground.

A square hole allows for the greatest root penetration and growth, especially for containerised plants whose roots are used to growing around in a circle. Loosen up the soil at the bottom of the hole with a fork and also the sides if they appear compact.

4. Take the soil you have dug and mix in compost so that it is three parts original soil, one part compost. You can add some further compost to the bottom of the hole and then fill in with your soil. There is no need at this point to apply a fertiliser, you can however sprinkle around the roots with mycorrhizal fungi (Rootgrow) to stimulate root-growth.

5. Place your tree in the hole and the fill in with your soil. Every now and then gentle heel in so that the soil is touching the roots. Air circulation is essential so don’t compact the soil too much.

6. You can plant a stake by the side of the rootball to give the tree some additional support if required. For a containerised tree we recommend two stakes as they require additional support. If planted in a sheltered site it may not be required and we advise not using a stake to improve the tree’s strength and flexibility. See our guide to staking trees.

7. After this you can form a bowl with the soil around the tree and fill with water. This will ensure the water doesn’t spill off and go directly to the roots. In the first several years it is important to look after and regularly water your young tree especially through periods of extended heat. Once the roots have grown out and the tree has established itself it will require less maintenance.

With this you have done your part in ensuring a long and happy life for your tree. You can also apply a mulch around the base to help it retain moisture, protect the roots and fend off weeds and disease.

How To, Liam, Planting, Plants

Pruning is essential to a productive and healthy fruit bush. For that reason we have created this step-by-step guide on how to prune a fruit bush which looks at those with a bushy and sucker/cane growing habit.

Pruning a Bushy… Bush

Fruit bushes witha bushy growing habit are all those species with branches spreading from one main trunk usually close to the ground level. These include most varieties such as blueberries, blackcurrants, redcurrants etc.

Bushy fruit bushes produce the most fruit on 2-3 year old branches and lose their vigour after that third year. Pruning therefore is the art of facilitating a constant cycle of rejuvenation keeping the plant young, healthy and heavy with fruit.

  • Pruning should be carried out in the winter while the bush is still dormant. I would advise waiting until early spring as the buds begin to develop. This will give you a clearer indication of which branches are worth keeping. Fruit buds will be more round and fat than their thinner vegetative counterparts.
  • In the first two years pruning is a light exercise, simply ridding the plant of anything dead, dying or diseased – the three D’s. As always when dealing with anything diseased you need to sterilise your pruning equipment and burn any of the affected branches or leaves after they have been pruned out to prevent the spread of contamination.

Before and After Pruning a Bush: The Desired Shape
  • As the bush has established itself pruning becomes a practice of training and increasing productivity. After removing the three d’s you want to maintain a good evenly spaced shape with the branches growing as horizontally as possible as these will be the branches capable of supplying the most fruit.
  •  As the bush grows older pruning should include cutting out any of the older more woody branches.
  • With this done you leave only the younger, more vigorous branches which crop the heaviest. This is better for fruit production and will help prevent the bush exhausting itself and falling into a biennial harvest.
  • Now you will want to prune out any crossing branches or areas of congestion. You need to open the bush up to sunlight and good airflow as to prevent the spread of pests and disease.  Suckers and low-hanging branches are more of an issue with a fruit bush.
  • If it appears as if the fruit will be resting on the floor cut out that branch. This helps prevent disease and pests from destroying your crop.

Pruning a Sucker Bush

Some bushes, mainly Raspberries and Blackberries, grow in a sucker fashion meaning that they grow new stems from the base of the plant year on year as opposed to having a truck or main branch. Both also only grow fruit on one year old canes and so it is essential to annually prune these bushes maintaining this cycle of rejuvenation.

Again this process should be carried out in late winter or early spring. More recently horticulturalists have realised that the old canes send carbohydrates back to the roots which can boost the plant’s vitality and therefore it may be worth waiting until spring time before you prune them out.

  • First of all tend to the 3 D’s.
  • Every year you need to monitor and remove those canes which have produced fruit during the harvest season. You can cut these out right at the base but leave a little length so the cut does not become contaminated from the soil and pests.
  • Lastly remove any weak or spindly looking branches. These won’t be able to bear much fruit and will simply limit air-flow and sunlight reaching the more productive canes.
  • You can now tie in these main canes to their support and expect a bumper crop as summer comes around!

Hopefully with this guide we have given you all the information on how to prune a fruit bush. As always check the specific requirement for your plant to ensure a healthy life and a bumper crop!

Current Issues, Liam, News, Trees

With the total world population now living in urban environments reaching nearly 50% it is becoming increasing apparent that we need to drastically rethink urban living. Urban forestry has been recognised for centuries as the key to beautiful city-scaping, however it is only more recently that studies have indicated trees are essential to a happy and healthy urban life.

In the UK alone air pollution kills 40,000 people every year. This year (2017),  during the record-breaking heatwave, there were emergency pollution alerts stretching from London across the South to Wales.

Moving towards the future we should aspire to smarter, greener urban living where any health complications due to pollution is deemed unacceptable. Despite facing a uniquely modern issue one of the most effective solutions is truly prehistoric; trees.

One large tree can absorb as much as 150kg of carbon a year and for every 10% increase in urban tree canopy, ozone is reduced by 3-7%. Not only do trees absorb CO2 they also reduce the level of other harmful air particulates which can cause a range of health issues from asthma to skin cancer. Research shows that a street lined with trees has a 60% reduction in the level of air particulates.

Reducing pollution, however, is not the only benefit which trees can give our urban spaces. There is a vast host of issues which can be solved with some smart urban forestry. National England state that trees save us £2.1 billion a year through the various positive health and social impacts they make.

A reduction in noise, stress and even crime are all effects of more trees. Scientific studies show our primitive instincts are more in-tune to forest environments and as such when around trees we become more relaxed, compassionate and active. Having trees in our gardens and streets go a long way to improving our personal and communal mood.

Tree’s make cities cooler too, potentially up to 8°C cooler! They can cut energy consumption by 30% on what would be used for air-conditioning. This is not to mention spaces in the garden; shade can go a long way to improving how comfortable an outdoor space can be.

When considering all of this, therefore, it is unsurprising that more expensive neighbourhoods have trees as a part of the street plan. In the UK alone the property value can rise by as much as 15% if the street is lined with trees. The aesthetic appeal is great, especially with brilliant autumn colours but not only that there is a proven reduction in crime in these areas due to the trees themselves.

With that being said, what can we do? Planting trees in our garden is a great start, as the old saying goes; ‘the best time to plant a tree was 20 years ago, the second best time is today.’ In our own private spaces we can allow the tree to grow to full maturity when the full benefits are possible. There are many urban developers negligent of this simple fact.

Beyond this, extensive urban forestry projects with maturity in mind should be on the agenda of every local councillor. In the long run, trees pay for themselves and have proven essential to healthy and enjoyable city life.

In this step-by-step guide we’ll not only show you how to mulch but explain the different kinds and what will work best for your plants and garden. Mulches are a thin layer of organic or inorganic material placed over a bed or the soil surrounding plants. The more attractive ones may grab your attention and look like a great addition to formal landscaping, but the practical uses are vast. 

Mulches are used primarily to improve the soil around plants, reduce weeds, increase fertility, help the retention of moisture and during winter can protect the roots of the plant from damaging frosts. Using the right mulch for your plants can help eliminate the need for chemical pesticides and fertilisers which is fantastic for your garden’s biodiversity. This all contributes to a healthy, great looking garden you can be proud of.

Now that Autumn is approaching it is the perfect time to start planning!

The Types:

You can roughly separate the different types of mulch into two categories; organic and inorganic.

Organic mulches are best for improving the fertility and overall structure of the soil. Over time the mulch will degrade and replenish the soils nutrients including nitrogen, potassium and phosphorus. Organic material also promotes biodiversity and encourages insects such as worms and spiders which will actually keep pests at bay while further enriching the quality of your soil.

For this reason an organic mulch is fantastic for plants try to establish themselves or are just generally hungry. Roses for example love a good organic mulch of well-rotted manure. More on this to follow.

Inorganic mulches are used to protect the soil around the plant and can also have an aesthetic edge to them. The benefits include locking in water to the soil, keeping weeds at bay and unlike some organic mulches it won’t wash away which is brilliant if you are planting on a slope.

Bark and Wood-Chippings

Here is a mulch which is attractive but also helps improve your soil’s nutrients and structure as it rots down. It also allows water to flow through it without binding throughout the year and really is a fantastic for pretty much all plants and circumstances. The only issue with it is that it is difficult to move or work around and so is best for around trees where you won’t be doing any more planting. Bark and wood-chippings will last you through the year and maybe even two depending on the grade, see how far it has broken down and replace if necessary.

Leaf-Mould

Leaf-mould is arguably the most nutritious and nature-friendly mulch you can apply. Pretty much every plant loves it and what’s more it can be completely free! It may not look like the most attractive mulch but apply in Autumn and by spring it will have blended in with and really enriched your soil. The only major drawback is that leaves do take some while to decompose and if you plan to DIY this is something you plan for a year in advance.

Collect as many leaves as possible in black bags and cut some small holes to let the air in. Ensure the leaves are thoroughly wet as leaves break down through fungi. Come next Autumn you’ll have some of the finest and richest mulch money can buy… not that you have to spend a penny! Of course, leaf mould is available to purchase in fairly substantial bulks.

Compost

There are two main reasons why compost can make a great mulch: 1) It is packed full of nutrients ready to leach down into the soil and 2) It is something you can make yourself free of charge. Additionally it helps with keeping the soil moist and fending off weeds. One thing to look out for however is that no weeds have made their way into the compost as these will simply sprout up from the compost and steal your plants nutrients.

Manure

As I’ve briefly mentioned before, when it comes to roses and other phosphate hungry plants nothing compares to some well-rotted manure. Like a compost that has gone through a far more strenuous decomposition process it is packed full of nutrients and its dense texture protects the roots and keeps the water locked in. It is also a really great mulch for trees and shrubs although to prevent waterlogging it may be worth mixing with some sand to allow for greater drainage.

Manure – As is Comes From a Stable or Farm

Gravel, Slate and Stone Chippings

There really isn’t a great difference here between them as you will want roughly the same thickness of layers. Stone mulches are fantastic for drainage and keep the soil underneath moist. It is also brilliant for retaining heat and so should be used for plants that are used to very hot conditions and can be worked into a Mediterranean themed garden well. Overall many stone mulches look fantastic and can maintain a pristine look for formal garden structures. They do not however add any nutrients to the soil and can become too hot during summer for more tender plants and young trees.

When to Mulch

The best time to apply a mulch is in Autumn, as you come into bare-root season, and spring. You will need to apply the mulch when the ground is relatively warm and moist, avoid periods when it is frozen or waterlogged. When the ground is good to dig and plant, it will be good to mulch which is very handy!

How to Mulch

  • Before you apply your mulch first you have to prepare the soil. Clear the ground of any weeds and give it a watering if the soil appears too dry.
  • If you are reapplying a mulch now is a good time to break up any old layers which may have matted to allow better water penetration.
  • Then cover the ground in a layer of mulch roughly 2 inches thick. Avoid mulching right up to the stems of plants and trees as this can cause them to become soft and rot.
  • Level out with a rake to an even finish. This is imperative, some people mulch little mounds, especially around trees. This will cause the bottom of the trunk to grow soft and rot while also drawing water away from the roots.
  • If you noticed that your mulch has matted over the year and become a hard layer, simply break  and fluff up a bit.

You can apply a fertiliser on top of the mulch through the year if you wish. Follow these rules and you should be all set!
