Maintaining Fruit and Nut Tree Orchards

I have had a couple of emails this past week from people who want to know how to maintain fruit trees when they are growing them in lawn areas. By coincidenge, the next video that will be posted on this site deals with this topic and you can see how we maintain our lime trees. For ease of maintenance we have planted them in groups of 30. They are now 3 years old and are growing well.

Barring accidents, which include such things as untimely hail storms or strong winds, the amount of fruit you will get from your fruit trees will be determined by the amount of food that the tree has available to it to create the fruit. If the soil is nutrient rich, well drained and has a high (10% or greater) level of organic matter, then the tree will produce an absolutele abundance as long as there is plenty of water and sunshine. Unfortunately most soils aren't as good as they should be so you have to make a habit of feeding your trees regularly - at least once every couple of months.

Soils are generally deficient in several minerals, have less than optimal organic matters and may be poorly drained or too sandy. My rule is that if I want my trees to produce, say, 100 kg of fruit per year, I will need to feed them the right amount of the food they need so that they can do this. If I value the tree's production at $4 per kilo, then my tree will give me $400 worth of fruit per year. So that it can do this, I give the tree 1/10 of the value of that fruit in the form of nutrients. This means I need to spend $40 per year on each of my trees. If you give your tree nothing, it will give very little in return.

I think an investment of $40 to get $400 worth of fruit is pretty good value, but the problem is that first you have to believe that the tree will give you the fruit and second you have to be prepared to make your investment before you reap the harvest!! Most people think it is sufficient to plant the tree and let nature look after the rest. Unfortunately, it generally doesn't work this way.

To feed your tree you can give it at least some of the following: blood and bone, lime, a really good all purpose fertilizer, molasses, boron, fish or kelp fertilizer, soft rock phosphate, silicon in the form of diatamaceous earth and lots of organic matter. Trees like to be fed regularly, so the rule is a little, often.

Don't dig around the trees. This damages the root systems. Cover the ground area with mulch keeps the weeds under control. Use cardboard to stop light getting to the weeds. Think of the area around your tree as a mulch pile and keep adding to it, remembering not to pile anything too close to the tree truck. Take your mulched area right out to the drip line of the tree so that you can mow right up to it. Weed the area by hand whenever necessary and pile the weeds back under the tree. Weeds make really good mulch.

The reason for not using weedicides around your fruit trees is that the weedicides kill the soils' micro-organisms. Through their root systems, your fruit and nut tree give out 50% of all the sugar they produce through the process of photosynthesis. The reasons they do this is to attract billions of fungi and bacteria to live around their roots. A tree must consider these microscopic creatures must be pretty important for them to give them so much of the food they create. If the trees consider them to be important, don't you think it might be foolish to use weedicides which kill those micro-organisms? All the orchardists I spoke to when writing my book "Transition Farms" told me that once they realised they had to stop using Roundup to control weeds, their whole farming operation improved significantly.

Growing fruit trees is not difficult but it does require on-going investment to keep the trees healthy and productive.
