How to grow olive flowers? A full breakdown of the cultivation methods
Watering
When growing olive flowers, keep the soil moist and make sure there is plenty of water. Never let the soil dry out, which would leave the olive flowers short of water and cause the leaves to wither and die.
Fertilizing
For young olive trees, fertilize mainly with nitrogen fertilizer, suitably combined with other fertilizers, following the principle of frequent light applications, generally once every two months, or apply once before and once after each flush of new growth. For fruiting trees, fertilize mainly with nitrogen, phosphorus and potassium fertilizers. Under the outer edge of the canopy's drip line, open a ring trench 20 cm deep, or two half-moon-shaped trenches, and apply the fertilizer into the trenches. If it is liquid fertilizer, cover with soil after it dries; if it is dry fertilizer, cover with soil immediately after application.

Cultivation methods for olive flowers
Pruning
Olive trees should be pruned in early summer; pruning allows the flowering branches of the olive flower to sprout flower buds again.
Pests and diseases
The common disease of the olive flower is anthracnose, which can be treated by spraying a 600-fold dilution of copper oxychloride solution.
Soil
The olive tree is a world-renowned, premium quality woody oil tree species characterized by "high yield, high quality and high efficiency". It is a strongly shade-tolerant tree that likes to grow on well-drained plots, is drought-tolerant and has strong adaptability to soil, being able to grow in slightly alkaline sandy loam and in clay soil rich in lime.
Do you all understand the effects of the olive flower now? In traditional Chinese medicine, the olive has long been called the "fruit of the lung and stomach" and has excellent benefits, but be sure never to eat it in excess, and always follow your doctor's advice before eating it in moderation!!
How to grow olive flowers? Cultivation methods and precautions for olive flowers
[Common questions]How to grow olive flowers? What are the cultivation methods and precautions for olive flowers?
[Expert answer]The cultivation methods for olive flowers are actually fairly simple. For gardening enthusiasts growing them in pots, it is essential to know how to care for them. Below, we introduce the cultivation methods for olive flowers.
1. Planting methods
A. Planting large seedlings:
When planting, the roots and soil must be closely integrated. The trunk only needs to go 6 cm into the soil. Seal the top with yellow clay, and wrap the trunk with straw to prevent wind and sun exposure from causing water loss. The straw must be 10 cm above the ground and must not touch the soil, so as to avoid attracting termites. Water after planting, and note: (1) lifting the seedlings and planting must be done very carefully, do not break the root bark or damage the root tips; (2) do not put base fertilizer in the hole, use only easily rooting red-yellow topsoil; (3) the soil must be pressed down firmly, which is the key to survival; (4) after planting, set up protective supports.
B. Planting small seedlings:
Planting time: from Grain Rain to Start of Summer is preferable.
Olive tree planting method: use burnt soil and leguminous green manure as base fertilizer in the hole, and sprinkle 1 jin of lime in each hole to prevent termite damage. When planting, mix surface fine soil with water in the hole to make a slurry, plant the seedling into the slurry so that the lateral roots spread out naturally, then cover with fine soil and press firmly so that the roots and soil are fully in contact.
2. Fertilizer and water management
(1) Fertilizer: major elements - nitrogen, phosphorus, potassium, calcium, sulfur.
A. Fertilizing young trees:
Mainly nitrogen fertilizer, suitably combined with other fertilizers, following the principle of frequent light applications, generally once every two months, or apply once before and once after each flush of new growth.
(2) Fertilizing fruiting trees:
Three times a year: namely pre-flowering fertilizer: around March, nitrogen; or: pre-flowering fertilizer
Post-fruit fertilizer: around October, nitrogen and potassium; flower-strengthening and fruit-strengthening fertilizer
Flower bud differentiation fertilizer: November-December, nitrogen, phosphorus, potassium; post-fruit fertilizer
Fertilizing method: under the outer edge of the canopy's drip line, open a ring trench 20 cm deep, or two half-moon-shaped trenches, and apply the fertilizer into the trenches. If it is liquid fertilizer, cover with soil after it dries; if it is dry fertilizer, cover with soil immediately after application.
3. Shaping and pruning
(1) Shaping young trees:
After the seedlings have survived planting, head them back when they reach 1-1.5 m tall. Generally cut at around 0.8 m. Select and keep 3-5 shoots in different directions as main branches. When a main branch is too long, cut it back at 60 cm. Keep 3 side branches on each main branch, and handle them level by level thereafter, so that they form a canopy that bears early and yields well as soon as possible.
(2) Pruning fruiting trees:
For trees just coming into production, in principle light pruning is the main approach, mainly removing overly long branches to encourage side branches; for pruning at peak production, the main aim is to regulate the ratio of vegetative growth to reproductive growth; for later pruning, the main task is to remove dead branches, shaded branches and diseased or pest-damaged branches inside the canopy.
[Editor's comments]There are many varieties of olive; our country alone has seven, two of which are cultivated as fruit trees, while most of the others are grown as ornamental plants. The olive flower is the national flower of Greece and a symbol of “wisdom, courage and victory”. The editors of First Agricultural Economics above have introduced the planting and care methods for olive flowers, and we hope this article is helpful to you.
