Greenhouses because of controlled environment, can almost enable to reach an extended growing season with a much better degree of health and yield of fruit trees. Gardeners using advantages given by the greenhouse grow a range of varieties of fruit trees, which may not be possible otherwise depending on their climatic region. Here’s an all-inclusive guide on how to grow fruit trees in a greenhouse.
Benefits of Fruit Trees Grown in a Greenhouse
- Long Growing Season: Greenhouses provide protection from harsh climatic factors, thus allowing for a longer growing season and sometimes year-round cultivation. Now, you can control temperature, humidity, and light, providing an optimum environment for fruit tree growth.
- Greenhouses: Can be sealed, locking out many pests and diseases and hence raising the threshold against pesticides and acaricides.
- Better Yield and Quality: In case of fruit crops higher yields are possible with fruits of better quality.
Selecting the Right Type of Fruit Trees
Not all fruit trees are fit to be grown in greenhouses. The following has to be checked up while picking up trees:
- Size of Trees: Better to choose dwarf and semi-dwarf varieties as they are relatively easy to handle and require less space.
- Chill Hours: Many cultivars of fruit trees require a certain period of cold for fruiting. Make sure that the greenhouse can be brought to this condition or select low-chill-hour varieties.
- Pollination Needs: Some trees need pollinated in a cross-pollinating manner. In this circumstance, either choose self-pollinating varieties if room is scarce or plan to provide for hand pollination.
Prepare the Greenhouse
- Situating and Frame: The greenhouse should be an aspect of catching all the sunlight as much as possible. It should always faces south. It must be a strong one to endure or resist the local weather.
- Ventilation: Proper ventilation is key to avoiding overheating. It is also quite essential for the circulation of air. Vents, fans, and exhaust systems will help control temperature and humidity.
Heating and Cooling
Depending on your climate, you may need extra heating in winter and cooling in summer. Options include electric/gas heaters and shade cloths.
1. Lighting Supplemental: Lighting might be a necessity, especially during the shorter days of winter. Lately, grow lights are employed in a lot of applications because of their energy-saving characteristics with regard to promoting growth.
2. Irrigation System: Drip irrigation system; this is very efficient and helps to maintain the moisture at the same level. The system should be automated, ensuring watering regularly.
Planting and Maintenance
- Soil Preparation: Quality-in, well-drained growing media or raised beds to enhance better control of the soil conditions and giving adequate root space.
- Plant: Space trees wide enough apart. These dimensions vary with different tree varieties, so make sure and look up the specific spacing for your trees. Plant to the same level as the nursery containers.
- Water: Fruit trees need consistent soil moisture, but over-irrigation will do more harm than good due to the possibility of fostering root rot. Monitor soil moisture levels and only water as needed for the time of year.
- Manuring: Apply a balanced and slow-acting manure to meet the basic requirement. Watch out the trees for deficiency symptoms and manure accordingly.
- Pruning: Regular pruning is very important to maintain tree shape, remove dead or diseased branches, and stimulate the growth of fruiting wood. Prune in the dormant season or as required.
- Pollination: Even when growing self-pollinating types, hand-pollination might need to be carried out. The pollen has to be transferred from one flower to another by taking a little quantity on a small brush if natural pollinating agents are not used.
Management of Pests and Diseases
Though plants are grown indoors, the set up may not be free from pests and diseases. The major issues and their remedies are as follows:
- Aphids: This is a small insect, which leads to damage to leaves; also, it spreads diseases. Biological control may be carried out by introducing one of the beneficial insects, namely, ladybird larvae or using insecticidal soap.
- Spider Mites: These are a common pest problem and proliferate in weather that is hot and dry. Increase humidity and use miticides if necessary.
- Powdery Mildew: This disease appears as a white powder on the leaves. It helps in air circulation; fungicides should be applied as control.
- Root Rot: Due to over watering, in lack of proper drainage. Soil should be properly drained, and water should not be over-used.
Seasonal Care
- Spring: This is a very important time for the herbaceous perennials because this is actually the phase where they begin to start building mass. They should be supplied with adequate water, pests should be controlled, and a schedule of fertilization started.
- Summer: Water, prevent overheating, and keep them moist. Continue to remain vigilant against pests and other diseases that may affect the plant.
- Fall: Get ready for the dormant phase of this plant by reducing water and stopping any form of fertilization. Harvest ripe fruits, and a bit of pruning required.
- Winter: maintain a minimum amount of water and ensure proper temperatures in the greenhouse. Prune trees and give necessary care for next season growing.
Special Considerations
- Container Growing: If space is a problem, then one may grow in large containers, so that one can manage the soil conditions and move trees .
- Hydroponics: Are a way that the fruit tree has a chance to increase the productivity of the limited space for agriculture and subsequently decrease the diseases that are soil-borne. This, however, is relatively costly in management of the nutrient solution, and water quality.
- Selection of Varieties: Check and identify the varieties available that are most responsive to greenhouse conditions. Frequently chosen species are citrus, fig, peach, banana, and papaya.
Growing fruit trees in a greenhouse has its advantages and can yield fresh, self-produced fruit each season. As long as the right varieties are selected, the greenhouse environment is appropriately fixed up, and an overall amount of regular care is put in, it can be done successfully, raising flourishing or productive fruit trees. It really only takes a tiny bit of labor and a little bit of care in order to turn the greenhouse into a fruitful, blossoming paradise.
