Growing Fruits

Greenmantle has always been committed to the organic approach to horticulture. This applies both to the nursery stock we sell and our own personal garden and orchard. We believe that in the long run, organic methods will promote healthier plants, people, and planet. Of course, we realize that not everyone agrees with this philosophy, and we also understand that growing "clean" fruit organically can be a very difficult and elusive goal for customers, particularly in humid regions of the country.

For those who wish to pursue a program of fruit culture that eschews dependence on chemical inputs or at least uses less than conventional methods normally require - we offer the following suggestions:. Natural organic orcharding begins with the soil. Eventually, your trees' roots may mine every square inch of your orchard ground in search of nutrients.

When possible, begin a soil-building program before the trees are planted. And develop a long-range plan to manage and maintain the tilth of your soil. The organic and bio-dynamic movements have developed many useful methods legume cover-cropping, mulching, compost dressing to achieve the goal of sustainable orcharding. While building up the tilth and organic content of the soil can solve a multitude of problems, certain situations may require additional "inputs".

Sometimes a comprehensive soil test will indicate a specific nutrient imbalance that needs to be corrected; the N-P-K paradigm seldom tells the whole story. Fruit trees can be very sensitive to mineral deficiences. Supplements that provide major nutrients like calcium, magnesium, and sulfur as well as minor nutrients such as boron, copper, and zinc may bring about dramatic improvement in tree health and fruit quality.

Compost teas, fish emulsion, and seaweed meal are all valuable sources of trace elements. The latter approach may offer some extra benefits in increased disease-resistance and cold-hardiness. Greenmantle's Chief Fertilizing Officer bestows his approval on some product. Develop a sense of place - and understand its inherent virtues and limitations. Soil, climate, and microclimate will affect every decision.

Once you determine what can be expected to grow well - and what will be marginal, experimental, or impossible - you can make realistic choices. This learning process might entail trial-and-error planting, consultations with experts, as well as checking with more experienced neighbors. Our own education meant visiting numerous abandoned homestead orchards and interviewing local old-timers who knew fruit.

Plus lots of mistakes and failures. Perseverance - we hope - will further Plant carefully and provide appropriate aftercare and protection.

Planting depth and orientation toward the sun are also critical considerations. Too deep or too shallow will cause a multitude of problems later on. Newly planted trees should be given a solar orientation that minimizes damage from sunscald.

Usually this means pointing the graft scar to the north so that the initial topgrowth leans toward the south. A slight tilt of the whole tree in this direction might be useful. In addition, a coating of whitewash or paint white exterior latex should prevent sunscald and the consequent girdling by flatheaded borers. Chrysobothris femorata - Flatheaded Apple Borer.

It preys particularly on young, drought-stressed trees. Establishing your trees of course means protecting them from marauding mammals deer, rabbits, dogs, rodents, etc. Young trees that have been defoliated by grazing animals may never really recover their health and vigor - they are certainly more prone to sunscald, borers, poor structure, and stress-related diseases. Good fences, at least in the early years after planting, are an absolute requirement in most regions.

Finally, we cannot over-emphasize the importance of adequate irrigation during those critical first years. Here in Northern California, drought stress leads to stunted, weak trees that cannot support the weight their own fruit. And for young trees, this situation is yet another invitation to borer devastation. Figure out a schedule that provides deep regular watering - at least till the tree is firmly established. Foxwhelp apples are honestly depicted by the great British pomologist and illustrator Thomas Hogg as very susceptible to apple scab.

Foxwhelp of course, is regarded as the premier hard cider apple of Great Britain, so a little blemishing can't hurt. Who knows, maybe the scab even enhances the flavor of the fermented brew? At any rate, a working cider press is a godsend to the organic apple grower….. Cultivate reasonable expectations. A misguided quest for superficial perfection too often becomes the justification for toxic sprays.

This is called "clean" fruit. Modern cosmetic standards for fruit may be somewhat unrealistic. Even here in California, with low humidity and no rainfall during the growing season, scab can blemish a certain percentage of our apple crop - depending on variety. Since we don't market much fruit, this doesn't bother us. At any rate, less than perfect fruit can make fine apple sauce and cider. Of course, some kinds of fruit are easier to grow organically than others.

Make informed choices for both variety and rootstock. Nowadays, fruit growers have many options to choose from, and these may include disease-resistant selections: scab and fireblight resistant apple varieties, fireblight resistant pears, peaches immune to leaf curl. Just make sure that you need this type of resistance. If a disease is not a real problem, then ordinary varieties may produce higher quality fruit.

Also, it is useful to remember that even the disease-resistant varieties are still susceptible to insect damage. Bartlett Pear - An old classic that still dominates the marketplace, Bartlett goes back to 's England, where it was originally known as "Williams Bon Chretien". It came to North America a generation later and was renamed "Bartlett". We grow a strain of this variety that has been selected for improved resistance to fireblight by researchers at the University of Illinois - Urbana.

A sandpear hybrid like Kieffer may be very appreciated by pear growers in a fireblight infested region like Mississippi - but why plant this gritty fruit in Northern California or Oregon where exquisite dessert varieties like Comice and Bosc flourish? Sometimes the decision-making process is not as clear-cut or obvious.

We have long been fascinated by the quandary afforded by disease-resistant apples: Is it better to grow a good scab-resistant variety like Liberty - or a great, but scab-prone apple like Spitzenberg? But we expect that many of our customers will ponder this dilemma.

Rootstock selection can be even more critical to the health and longevity of the tree. Natural vigor may require a taller ladder, but it often means a healthier orchard. Knowing your soil type and its drainage tendencies is an important consideration. For instance, MARK apple rootstock thrives in heavier clay loams, but seems poorly adapted to sand typical of irrigated high desert plantings. Mazzard cherry tolerates winter "wet feet" better than most other cherry roots.

And the Malling- Merton apple series eg. MM was developed in part to resist soil infestations of wooly apple aphis. Organic growers should also keep in mind that many modern orchard practices were developed in conjunction with a heavy spray program. So intensive close spacing of dwarf trees in trellised rows typically means more fungus diseases unless regularly sprayed. Likewise, many genetic dwarf varieties, especially peaches, have such a dense growth habit that disease problems are inevitable without chemical intervention.

Caused by the fungus Taphrina deformans, Peach Leaf Curl plagues Prunus persica wherever wet spring weather is common. Trees can recover from the damage and still bear a crop, but the disease obviously results in stress. Don't become so focused on the fruit that you forget the tree. Healthy fruit grows on healthy trees. Too many people seem obsessed about getting a precocious crop off of their young trees.

This can lead to broken or misshapen branches and stunted trees. It is often best to strip off a premature fruit set to allow the tree to develop a strong, well-formed framework that can hold a crop year after year. Getting a young tree established during its adolescent period is crucial to long-term success. Judicious pruning and training means less remedial damage control later on.

A properly structured tree will allow optimum air circulation and light penetration; this results in better quality, less blemished fruit. Too much openess, however, can lead to sunburn and borer damage. Again, we do recommend the use of white paint on young trunks when appropriate. Balanced feeding and watering is, of course, essential.

The orchardist should carefully monitor shoot growth - both length and caliper - and adjust irrigation and fertilization accordingly. This requires some experience with "normal" growth rates for trees in a particular zone. Here in California, drought stress - and concurrent lack of vigor - can frequently lead to attack from the flatheaded apple borer. On the other hand, excessive watering and fertilizing - whether chemical or organic - can make a tree more susceptible to disease. Fireflight Erwinia in particular likes to prey on apple and pear trees that have been "hyped" with too much nitrogen.

Go a little slow with the manure teas and fish emulsion - even though they are certified organic Fireblight Erwinia amylovora damage in top of old pear tree.

This problem can often be contained by careful pruning and good cultural practice. In regions where fireblight means an ongoing struggle, growers should consider resistant varieties and rootstocks. Learn about non-chemical methods of pest control appropriate to your region. For many years, organic practitioners have been developing "non-toxic" approaches to monitoring and controlling insest pests eg. Methods include trapping, releasing of predatory insescts, and biological sprays.


Apple Production and Variety Recommendations for the Utah Home Garden

Jump to navigation Skip to Content. It is important to select fruit varieties which are suited to your climate, and have some resistance to the insect pests and diseases found in your area. Your local nurseries generally have the best information on fruits suitable for local conditions. Deciduous trees like pomefruit apples, pears, quinces and stonefruit peaches, plums, nectarines, cherries need a certain amount of winter chilling winter cold to produce fruit and different varieties will have a different chilling requirement.

Fruit Tree Pests & Diseases

Just as apples, pears, sweet cherries and other stone fruits e. This can provide the homeowner with edible fruit, valuable ornamental qualities, and possibly access to a favorite variety that may not be available in the local market. What many homeowners may be unaware of is the fact that they are legally responsible for controlling insect pest and diseases in fruit trees on their property. Start by reading these short fact sheets. Then if you still want the fruit tree, we offer resources to improve pest control and horticulture. Home gardeners can protect their own fruit from pests and diseases as well as keep commercial orchards safe from pest infestations and spread of disease by regular spray programs several times a year. Codling moth and Western Cherry fruit fly are pests that are not allowed in commercial crops, and fruit infested with these insects are rejected in both domestic and international markets.

Think Twice, Plant Once: Does a Tree Fruit Orchard Make Sense for Your Farm?

Summer fruits are among the most delicious things we eat, and ripe summer fruit from your own garden is even better. To keep your fruit trees healthy and producing fruit, learn how and when to prune fruit trees. Below are fruiting trees that grow well in northern Virginia and that we find are generally the easiest to care for. Choose a south or southwest position to plant your tree, and make sure it receives full sun.

Nurseries grow virus-free plants not just for the export market, but for the domestic market as well. Producing virus-free plants is important because viruses can stunt tree growth, reduce fruit yields, produce deformed, off color foliage, and increase susceptibility to other diseases.

Most fruit trees are basically easy to grow, so don't worry if you are not an expert gardener - watering is the only task which is really essential.. The varieties we classify as Easy are those which we think are particularly well-suited to the first-time fruit grower. These varieties are reliable croppers with simple pollination requirements. We classify some varieties as Average.

Verticillium wilt of deciduous fruit trees

A large number of diseases occur in the northeast because of the frequent rainfall that favors their spread and development. The most effective method of prevention is to plant varieties that have resistance. Where that is not possible, keeping a clean orchard by removing diseased plant parts can slow the spread. In many cases, the trees will tolerate mild cases of disease with no harm. Apple scab is recognized by the brown or olive green spots on leaves and the black spots on fruit.

If you have not yet planted your fruit trees, you have the opportunity to select resistant has broken down in wild apples, and may do so in the case of.

Fruit trees: the five easiest to grow

RELATED VIDEO: Disease Resistant Apple Trees – Family Plot

Many gardeners are interested in fruit trees, but are often unaware of which species will do well in Illinois and also the amount of work involved in growing tree fruit. Be sure to do your homework in planning a tree fruit planting, as not all tree fruits will do well in Illinois. Most of the varieties of tree fruits are grafted on dwarfing, semi-dwarf or seedling rootstocks. Trees grafted on dwarfing rootstocks require less space compared to trees grafted on seedling rootstocks. Due to the limited space in the backyards, homeowners prefer growing trees on dwarfing or semi-dwarfing rootstocks as they require less space compared to trees grafted on seedling rootstocks.

The prospect of growing fruit trees can be daunting — pollination groups, complicated pruning involving spurs and tips, countless tricky pests — but choose your variety wisely and you can sidestep many of the scarier aspects of fruit cultivation.

Pests & Diseases

First free yourself from the idea that fruit trees need to be in a separate part of the garden to ornamentals. This belief in 'appropriateness' in planting is comparatively recent; once upon a time cottage gardens simply grew whatever was useful or beautiful together in one area. Whether you have a small, inner-city courtyard or even just a balcony, there is always room for at least one fruit tree. To make the choice easier I've narrowed it down to a list of attractive, hardy, relatively pest-free, delicious fruits. So in return for all your gardening efforts, why not let your garden provide you with not only beauty but healthy, sun-ripened fruit? Looking for a bit more space? Then if you have a lawn, its time to assess just how useful it actually is and consider replacing it with fruiting shrubs and trees.

Growing your own fruit trees is a rewarding experience, and disease-resistant fruit trees make that experience much easier. We understand that the environment can pose challenges to growing fruit, but these varieties have a natural edge — with no genetic engineering! Here we feature some disease-resistant fruit trees from our offering for your convenience.
