If you want to make your garden as beautiful as possible, there are several things to consider. Here are three ways to improve your garden’s appearance.
Oranges are among the most commonly grown fruits in greenhouses as they can be quite easy to grow and provide you with the freshest possible fruit in the off-season. Plus, the taste of a fresh orange will always trump that of the one you will find in your supermarket. So, if you are planning on growing oranges in a greenhouse for the first time here are a few things that you need to keep in mind.
Choose the Right Variety of Oranges
Orange trees have many different varieties and you will have to figure out which one has the best chance of thriving in your region. New varieties keep popping up on a regular basis which can cause a lot of confusion for first-timers. So, it is best to ask a knowledgeable professional at the nursery to get a better idea of which types would be right for you if you are growing oranges in a greenhouse.
Regardless of which variety you go with, make sure you choose dwarf trees as they are best suited for a greenhouse environment as opposed to standard-sized trees. Even though the fruit is exactly the same, these trees take up a lot less space and are much easier to manage.
Select the Best Containers for Orange Plants
Selecting the right containers for your trees is very important as they determine how big your trees will eventually get. Look for high-quality containers that are at least 10 gallons. This will give your plants plenty of room to spread their roots and grow into manageable-sized healthy plants. Remember that orange plants tend to be top-heavy which is why they require a pot that is quite deep to balance out the weight.
Maintain the Right Temperature for Orange Plants
Start by buying the right greenhouse. Make sure it has a heavy cover that will help maintain optimum temperature during the winter months and keep down the cost and side windows that will help regulate external airflow and provide better air circulation. During the day the plants need the temperature to be above 70 Fahrenheit, whereas during the night the temperature must stay above 50 Fahrenheit, otherwise, the plants will start drooping.
Orange Tree Watering and Drainage
In order for your plants to thrive, you will need to make sure you water them properly. However, many people make the mistake of overwatering their plants which can end up causing different diseases. So, use pots that have a lot of drainage holes to make sure that the water doesn’t pool near the roots. Because orange trees don’t like wet feet. Another way to give your pots added drainage is to place them on drainage racks that keep the bottom of your pots from coming into direct contact with the ground, making sure the drainage holes don’t get blocked. Some gardeners also pack pebbles or peanuts at the bottom of the pot to accelerate the water drainage.
Use a potting mix manufactured specifically for container cultivation of citrus trees. It will make sure that the root system gets enough drainage. When you see the soil getting dry and the leaves start curling, water the plants to the top of the plant. You can reduce the watering during the winter season. The plants don’t need too much water during these months, however never let the soil get dried out completely.
For growing orange trees you need a water-soluble fertilizer with a high nitrogen concentration. It is best to use a time-release fertilizer while planting. Much easier than adding fertilizer to your plants regularly throughout the season.
However, If you want to add fertilizer regularly throughout the season then make sure to fertilize the trees every week in spring and summer. Whereas, during the winter season fertilize only every two weeks and use a low-nitrogen fertilizer. If you notice the temperature going below 55 Fahrenheit during the winter season, it is a sign that you should stop adding more fertilizer.
Make sure you are using a fertilizer that is formulated specifically for growing orange trees. Remember to keep an eye out for any yellowing leaves throughout the season. It can be a sign of iron chelate deficiency.
Fight Pests and Disease
When growing oranges in the greenhouse, you need to be aware of different pests. Pests like whiteflies, leafminers, spider mites, aphids, and mealy bugs can potentially destroy your plants. However, if you use a high-quality sprayer to spray insecticidal soap on your plants you can easily keep most of these pests away from your plants. Some gardeners also realize beneficial insects like ladybugs in their greenhouses that take care of all the aphids and other pests.
One of the best ways to protect your plants from pests and diseases is to make sure your greenhouse always has optimum air circulation. Be sure the pots are not placed too closely together. If you plan on moving your plants outdoors during the summer season make sure to use insecticidal soap before bringing them back into the greenhouse. During the fall to make sure they don’t bring any pests with them. Also, keep pruning the trees as necessary and remove suckers that appear below the graft and water sprouts. This will help keep the plants healthy and shape them at the same time.
When to Harvest Oranges
If you are planting oranges for the first time you might have a hard time recognizing when your oranges are ripe and ready to be picked. Don’t harvest your oranges prematurely. They don’t tend to ripen after they have been picked unlike lemons and some other fruits. So, make sure they are completely ripe before you start harvesting.
The longer the fruit stays on the branches the more flavor it will have. Also, the sweeter and juicier it will be. You can tell when the oranges are ripe by checking their weight. Ripe oranges are generally heavier than non-ripe oranges. Moreover, ripe oranges are brightly colored and give a bit when pressed.
