Growing fruit in residential areas can be an interesting, fun and rewarding hobby. Many novices dream of plucking perfect fruit of trees or plants in their gardens. However, high quality harvests do not happen without knowledge and a great deal of work. Controlling pests (insects and diseases) is an integral part of the care necessary to achieve good results.
This blog provides guidelines for pest management in home fruit plantings, but good pest control is not possible if spraying is the only action taken. Success starts with selection of disease resistant cultivars and sites that are open and full sun. Cultural practices such as pruning and sanitation are also necessary for good pest control.
The Importance Of Plant Protection In Winter and Schedule of Spraying
Most fungicide (disease control product) and some insecticide (insect control product) applications are effective only if applied preventatively because it is not possible to control the pest satisfactorily after infection or infestation.
In very rainy seasons, sprays may need to be applied more frequently than the usual practice. Wet weather favours development of the disease-causing organisms; thus, more chemical protection is needed. Also, rains can wash off the pesticides (fungicides and insecticides). When rain occurs before a spray has dried or if rainfall totals more than 1 inch within 24 hours, the spray should be re-applied. However, do not delay fungicide application if rain is forecast because fungicides provide more benefit when applied before a rain than after. Protection from infection by disease-causing organisms is needed when plant surfaces are wet.
Thorough coverage of all aboveground plant parts is needed for good pest control. One of the biggest mistakes home fruit growers make is allowing plants and trees to grow too tall. If dwarf and semi-dwarf trees are selected and then maintained at a manageable height, it is easier to spray them properly as well as to harvest the fruit. Proper pruning practices also reduce the amount of spray needed and permits better coverage.
The type of sprayer used depends on the size of the fruit planting. For most plantings of small fruits or for a few small fruit trees, hand-pump sprayers are adequate. Trombone-type sprayers are helpful for taller trees. For the increased spray volumes required by larger home orchards, power sprayers are recommended.
Mixing a commercial spreader-sticker with the spray solution provides better coverage of slick surfaces, such as apple fruit or blackberry stems. See the pesticide label to find a suitable spreader-sticker.
The product labels give the rates, and those rates must be followed. The label rates are expressed as amount per gallon of water. The following table can be used to determine the amount of spray mixture needed.
Multipurpose Fruit Spray
Multipurpose fruit tree spray products are mixtures containing a fungicide and insecticides. Insecticides should not be applied during bloom because they will kill bees. It may be more convenient to purchase the fungicide separate from the insecticide. Multipurpose sprays are effective against some, but not all, pests.
Protect Pollinating Insects
Honey bees and other pollinating insects must be protected from insecticides, which will kill them. Do not spray fruit plants with insecticides while the plants are in bloom. The literature is mixed on the safety of copper products (copper sulphate + lime [Bordeaux Mixture], copper hydroxide) for bees, and some literature suggests other fungicides may negatively impact pollinator health. To reduce risk to bees, when applying fungicides during bloom (especially copper products), only apply products during late evening, night, or early morning when bees are not foraging.
To protect people and the environment, pesticides should be used safely. This is
everyone’s responsibility, especially the user. Read and follow label directions carefully before you buy, mix, apply, store or dispose of a pesticide. According to laws regulating pesticides, they must be used only as directed by the label.
Most of the pesticides suggested for use in this publication are low-toxicity materials; however, some precautions are still needed.
- Keep pesticides in the original, labelled container.
- Keep pesticides in a locked storage cabinet, away from children or pets.
- Read the label each time before you use the product.
- Wear rubber gloves, goggles, a long-sleeved shirt, long pants and a hat when mixing and applying pesticides.
- Handle the pesticide carefully when mixing. Avoid breathing dust or vapours. Wash any chemicals on the skin immediately with plenty of water.
- Never apply insecticides or fungicides with a sprayer that has been used for weed killers.
- Do not spray if it is windy.
- Mix only as much as you need. Do not store diluted spray mixtures from one application to the next. They will lose effectiveness and are unsafe.
- Observe the waiting period in days between the final spray and harvest (pre-harvest intervals) and re-entry requirements given in the following table and on the product label.
How Do Winter Sprays Work?
Just like the trees are sleeping and recovering during the winter, so are a lot of insects and diseases in their own way. They're going through a dormant period of their own and many of these insects and diseases will do their winter rest on the tree itself. Some examples might be mites, scales, or woolly apple aphids.
Some diseases, particularly bacterial diseases like fire blight, will be residing on the tree itself. And so we want to be aware of that. And in order to reduce the pest pressure or the disease inoculum when the season starts, there are some treatments that we can apply that we need to think about that will help to reduce the population say of overwintering mite eggs or overwintering scale. And by getting a jump on the season, it reduces the potential for those pests and diseases to be bigger problems in season than they would be if we didn't do anything.
One of the most classic applications is horticultural oil. And the horticultural oil would be applied in a dilute spray. And by dilute, I mean maybe 1% to 2% oil in water, and that would be applied to the entire surface of the tree. What the oil does is it essentially smothers the mite eggs or the scale or the woolly apple aphids.
Some other sprays can be applied, copper being one of them, lime sulphur would be another, and also neem oil and Karanja oil which are seed oils from trees in India have also become very popular. They act differently than horticultural petroleum oils and they actually have some added benefits for the health of the tree, but in the dormant season, those are the basic options that we're dealing with to help with these overwintering insects and disease pressures.
When it comes to oils or copper and lime sulphur, if those products are applied when there's foliage on the tree, you can get what's called phytotoxicity. So these products can damage or burn off the leaves. And if it's even later than that, they could potentially burn the flowers or lead to roughened fruit.
And so, if it is known there is a mite problem or a scale problem, these products need to be applied earlier in the dormant season. Maybe in late January, mid to late March or so. At that time, you can apply them at a higher rate and have a greater impact on those pest species populations.
The sooner we get to that bud swell, bud break, and what we call green tip, which is when you start to see the very, very first hints of green tissue emerge, we need to reduce the rates so that we don't cause any phytotoxicity problems in the tree itself.
And so, by reducing the rates once the buds start to break, we're obviously going to have less efficacy against some of those insects and disease pests. But as well, those pests are starting to wake up and they become more susceptible. So, there's a little bit of a sweet spot.
We don't like to recommend applying anything too early in the dormant season. We also don't want to apply it too late because then we have to reduce the rates too much. So somewhere right around what we call delayed dormant. So just as the buds start to swell, but before there's that green tissue, that's really the sweet spot of when you want to apply these for the most efficacy.
Spraying Different Plants
Proper identification of insect pests and diseases is an important step before attempting to control the pest. Not all plant problems are caused by pests; some are caused by cultural, nutritional or environmental conditions.

Pruning is an essential task that needs to be undertaken throughout the year to improve the health and longevity of plants, shrubbery and trees. Winter pruning is the practice that involves shaping, clipping and preserving branches on a tree or shrub. Pruning in the winter is a great way to remove unneeded branches, allowing the organism to focus its growth elsewhere. As a leading greenwaste company we delve into the importance of pruning during winter.
When Is The Best Time Within Winter To Prune
Pruning apple and pear trees during winter is best done between November and March as the trees will be dormant. We recommend pruning in December and January when the cold weather settles sets in.
How To Winter Prune
Before you start clipping, it's important to make sure you have sharp secateurs or clippers. Keeping these clean is a great way to minimise the chance of infection when pruning. It is recommended to shorten the main branches by about one-third to encourage the development of new and existing branches. Make sure to leave side shoots un-pruned so that they can develop into fruit buds faster in the warmer months. Pruning in these colder months is a great way to see the structure of your trees, use the tree's skeleton to shape and evaluate what branches need shortening or removal.
Managing An Orchard - How We Can Help
Pruning one or a few trees can be difficult, let alone an entire orchard. Failing to prune could reduce the fruit yield they produce, it may also lead to weaker branches breaking or spoiling the fruit on the ground. If you have to prune a multitude of trees you can just stick to the essentials within pruning that include; keeping the centre of the tree clear of growth, removing branches that compete or rub against one another for space and the removal of protruding branches.
Making sure every tree receives the treatment mentioned above, will ensure that your fruit will flourish during its development in spring. Instead of trying to manage and deal with the trimming and maintenance yourself, our arboricultural experts can step in and help. Effective tree management does not only improve its health and appearance, it also helps the environment.

One issue that many keen gardeners will come up against from time to time is the issue of pests. As specialists in landscape design services, we know just how irritating it can be when all your beautiful garden plants are being eaten away. For this reason, we have written this guide to provide insight on some of the most common pests and how to deal with them.
Slugs and Snails
One of the most common pests you will encounter in UK gardens are slugs and snails. Both widespread and persistent, these can cause considerable damage to your garden. Often they will eat holes in leaves as well as flowers, bulbs and stems. Most at risk are new spring herbaceous plants and seedlings. Yet, both slugs and snails can be problematic in the garden annually.
However, there are a few natural deterrents you can use to limit the damage. For slugs, consider lining your borders with upturned eggshells or creating a rough area of sand around your plants. Both will work to deter these pesky creatures.
Prevalent in many gardens, ants although not official pests, can be irritating for many gardeners. Ant nests can cause damage to flower pots and lawns as little heaps of soil appear above the surface. Often, these pests are best left alone, but you can brush away the aforementioned soil heaps on dry days.
Small insects such as this can be problematic for a range of greenhouse plants. Thrips will suck sap from plants causing pale mottling and brown marks to appear on the surface of leaves.
They are active all year round within greenhouses and cause a lot of damage between April and September. In order to remove these, hand sticky blue sheets among plants that can trap insects.
Don’t let the damage caused by these garden pests deter you from maintaining your garden spaces. With a few of these handy tips pests such as slugs, snails, glasshouse thrips and ants can be controlled. A few additional pests you may want to be aware of include; Box tree moths, Tortrix moths, Rosemary beetle larvae and Viburnum beetles.
