Harvesting Oranges: Learn When And How To Pick An Orange
The first thing you need to know is that there are two types of orchards. There are those where the trees grow directly into the ground and those where they grow up a trellis. You will have seen both types of orchards before, but never at the same time!
There are three main ways to harvest an orange:
1) The Tree Method – This method involves cutting off the top part of the tree and then climbing up it to reach the fruit.
The tree method is usually used for large trees like sugar maples.
2) The Trellis Method – This method involves using a rope or net to climb up a trellis and then pull yourself along with your hands until you get close enough to grab the fruit.
This method is best suited for small trees like pears and peaches.
3) The Hand Pull Method – This method involves grabbing the fruit with one hand while pulling with the other.
Usually used for smaller trees such as apricots and nectarines.
How Do I Know If My Tree Is Tall Enough For Me To Reach?
You may want to consider whether you would like to harvest your own fruit or buy some from a farmer’s market. If you would rather buy it from a farmer’s market then you can skip to the next section. If you would like to try and harvest your own then you need to make sure that your tree is tall enough for you to reach the fruit. Pick a flower from the tree and extend your arm out as far as it can go. The tip of the flower should almost touch the ground. If it doesn’t then the tree isn’t tall enough for you to pick from.
How Do I Pick The Fruit?
The first thing you need to do is climb up the tree. If you are using the trellis method then make sure that you use the rope or net that is already attached at the top of the tree and that you secure it to something sturdy on the ground before you start climbing. You may also want to have someone on the ground to make sure that the rope or net doesn’t come undone. If you are using the tree method then just make sure that someone is around in case you fall.
If you are using the hand pull method then just grab a fruit and start pulling yourself toward it. This may take a few attempts to get right and you may find that leaning away from the tree helps you get closer.
