What are the key points for growing potted lemons?
The main techniques for potted lemon cultivation are as follows: Raising seedlings and potting up. In the south, where cultivation is on a large scale, grafting propagation is preferable; in the north, where cultivation is on a small scale, cuttings are mainly used, or grafted seedlings can be purchased for growing. The lemon's root system has high requirements for water, nutrients and soil. The potting soil should be mixed to be permeable and airy, moisture- and fertilizer-retentive, and slightly acidic. Potting up and repotting can be done either after autumn or in early spring, flexibly according to the local climate.
Light and temperature: Lemon is a light-loving plant, yet excessively strong sunlight causes poor growth and development. Generally, at noon the plant needs to be moved to a suitable spot. The suitable annual average temperature for growth is above 15°C, the optimal growth temperature is 23°C to 29°C, growth stops above 35°C, and at -2°C it suffers cold damage. In summer, lemons generally do not need cooling; move them indoors before Frost's Descent and outdoors after Qingming, and they can overwinter safely.
Watering and fertilizing: Lemons need a fair amount of water during growth and development, but too much water easily causes root rot. Generally speaking, spring is the period of shoot growth and leaf unfolding, bud formation and flowering, so water moderately. In summer, with strong light and high temperatures, more water is needed. But it must be timely and moderate, otherwise fruit drop will result. Autumn is the period of autumn shoot growth and rapid fruit enlargement, so there must be sufficient water. Late autumn and winter are the flower bud differentiation period, when the potting soil should be on the dry side. Lemons quite like fertilizer; besides applying enough base fertilizer when potting up and repotting, the principle of light fertilizer applied frequently should be followed during the growing season. The number of fertilizer applications and the amount applied must be determined by growth vigor and phenological stage. For liquid fertilizer, well-fermented cake fertilizer water is best, with a cake-to-water ratio of 1:200. In the north, where the soil tends to be alkaline, ferrous sulfate can be added to the fertilizer solution to make a slightly acidic nutrient solution.
The fresh and lovely method for growing potted lemons - what are the key points for potted lemon cultivation?
Raise a pot of lemon with your own hands to add a touch of fresh green to your home. Wake up every morning to a fresh fragrance - that is the scent of lemon, and life is so beautiful. The small lemon tree gives off a natural lemon aroma and becomes part of a healthy life. Now follow the editor and learn how to grow lemons.
Materials to prepare:
1 lemon, 1 growing container, 1 transparent ziplock plastic bag, 2 wet wipes, 1 small pot of soil.
Growing steps:
Step 1 Cut the lemon open, trying not to damage the lemon seeds, then pick out the lemon seeds, wash them, and set aside.
Step 2 Use a tissue to blot up the remaining water on the lemon seeds, then remove the outer film of the lemon seeds with the tip of a fruit knife.
Step 3 Select a few lemon seeds that have been cleaned relatively perfectly. As shown in the picture, 9 seeds were chosen and arranged separately on a tissue, then another tissue was placed over them.
Step 4 Carefully put the tissue and lemon seeds into the ziplock bag, then use tape to stick the ziplock bag onto a window facing the sunlight, so the lemon seeds can fully enjoy the sunshine.
Step 5 You can check on them often. When you find that the lemon seeds have sprouted small buds as shown in the picture, you can take them out.
Step 6 Put them into the growing container prepared in advance and cover with nutrient soil.
The above is the method for potted lemons that I have compiled for everyone. I hope it is helpful to you. Please continue to follow Duorou Huapu for more information.
Key points for caring for potted Gardenia jasminoides
Gardenia jasminoides (detailed introduction) has evergreen leaves all year round and fragrant, elegant flowers, and is an important ornamental plant for balconies and courtyards. There are many varieties of Gardenia jasminoides, and caring for them in pots is very simple. Just follow the steps below for care!
Gardenia jasminoides (detailed introduction)
1. Choose suitable potting soil
Gardenia jasminoides likes acidic soil, with a suitable pH of 5 to 6. Prepare suitable soil before planting. If the soil's acidity and alkalinity are unsuitable, later care will be very troublesome.
For growing soil, usually choose leaf mold and peat soil plus half garden soil. Do not use coal cinder, or directly buy special soil for Clivia miniata, which is convenient and practical.
2. Fertilize reasonably
Gardenia jasminoides likes fertilizer. When planting, add decomposed cake fertilizer to the soil as base fertilizer.
During the growing season, use cake fertilizer and ferrous sulfate fermented into fertilizer water, and water with it once a week. A complete-nutrient organic liquid fertilizer can also be used.
During the bud stage, apply additional fertilizer 1 to 2 times, watering with a potassium dihydrogen phosphate aqueous solution, which can make the flowers larger and the fragrance richer.
When the summer temperature is above 35°C and the autumn temperature is above 15°C, stop fertilizing.
3. Water scientifically
Gardenia jasminoides likes a moist and humid environment. During the growing period from April to September, keep the potting soil moist, watering so that it dries and then gets wet. At night, you can spray to wet the leaves to maintain humidity. If the plant grows too vigorously, do not water at night; water after the sun comes up in the morning.
In alkaline-water areas in the north, when watering, let tap water stand for a day before watering. Every 3 to 5 days, water with a little citric acid aqueous solution, which can keep the leaves emerald green.
4. Give plenty of sun
The growth of Gardenia jasminoides needs sufficient sunlight. If placed in half shade for a long time, the flowering branches will be weak and slender. During care, except for shading at noon in July and August and during winter dormancy, it can be cared for in the sun at other times.
5. Good winter dormancy
Although Gardenia jasminoides is cold-tolerant, after enduring a severe winter, the root system of potted Gardenia jasminoides will be damaged, and spring recovery will be slower. But if placed indoors with heating, where the temperature is higher and light is insufficient, plant growth slows and flowering is later the next year. The best method is to place the pot in a 5°C environment to let it go dormant, or wrap the flower pot with insulation material and place it outdoors in a sunny, wind-sheltered spot to overwinter.
6. Prune appropriately
When the main trunk of Gardenia jasminoides grows to 20 cm, pinch off the tip, leaving 3 to 4 branches to promote branching. After flowering each year, prune lightly, cutting off weak and diseased branches. But in spring, Gardenia jasminoides must not be cut back at the branch tips, otherwise it will be difficult to bloom that year.
7. Repot and change soil at the right time
Gardenia jasminoides has strong vitality. Small seedlings grow from a few centimeters to several tens of centimeters, so they should be repotted according to the size of the plant. When the length of the plant's branches and trunk is 2 to 3 times the diameter of the flower pot, it needs repotting. When repotting, promptly prune old roots, replace half the soil, water thoroughly, and place in half shade for a week; after new buds grow, move it into the sun.
