How to fertilize potted gardenias and what time of year to stop fertilizing

Gardenia fertilization method.

1. Gardenia should be applied to cooked soybean cakes, sesame sauce residues, peanut bran and other fertilizers, which can be acidic after fermentation and rotting, but must be applied with thin fertilizer, avoid thick fertilizer, raw fertilizer, and do not apply fertilizer during the hibernation period

2. Stop watering gardenia before fertilization, and water thoroughly when fertilizing.

3. Gardenia peanuts are long-term, and the appropriate amount of fertilizer should be applied more when flowering, and fertilizer should be added once after flowering.

4. If the gardenia has been planted for less than three years, do not apply human feces. Excessive nitrogen fertilization will result in thick branches, large leaves, and thick green, but no flowering. When phosphorus and potassium fertilizers are deficient, there will also be no flowering or flower buds wilting and falling off.

3. Gardenia fertilization precautions.

After knowing what fertilizer is good for gardenias, it is very simple, although gardenias like fertilizer, but can not add too much fertilizer at one time, must be thin fertilizer and more application, must not be greedy and save trouble, otherwise it will cause thick branches, large leaves, thick green, it will lose its own appreciation effect. <>

Generally, the bottom fertilizer is applied in the potting, and the fertilizer is applied during the growth period and when there are flower buds [the fertilizer should be thin], and the fertilizer should not be applied for a while before flowering and in winter.

Potted plants are generally applied basal fertilizer before planting, non-acidic soil can usually be made of ferrous sulfate and soybean cake or other manure, after fully decomposed, with a ratio of 1-10 with water, it can be applied once a month, and the special alkaline soil can be appropriately shortened fertilization interval. This is liquid fertilizer. An easy way to try acidic soils is to boil some soybeans and put them in a bottle or other container.

Put it in the sun until it is fully fermented and rotten, you can dig a small pit on the outer edge of the pot soil about half or close to half of the pot, and put one to three grains of rotten soybeans

After applying plantar fertilizer (chicken manure, pig manure, etc.) before changing the soil in spring, it will be applied every month (self-made kitchen waste water, chicken, duck and fish offal, etc., melons and fruits, mildew melon seeds and peanuts and so on are fermented and rotted with water and diluted more than ten times with water) thin liquid fertilizer, so that thin fertilizer is applied frequently, and fertilizer is applied once after flowering, and fertilizer is stopped at the end of autumn.

Fertilization method: It is advisable to apply cooked soybean cakes, sesame sauce residues, peanut bran and other fertilizers, which can be acidic after fermentation and rotting, but must be applied with thin fertilizer, avoid thick fertilizer, raw fertilizer, and do not fertilize during hibernation. If it has been planted for less than three years, it is important not to apply human feces.

Excessive nitrogen fertilization will result in thick branches, large leaves, and thick green, but no flowering. When phosphorus and potassium fertilizers are deficient, there will also be no flowering or flower buds wilting and falling off.

Fertilization time: After planting, weeding and topdressing in spring and summer every year, human and animal manure, manure, compost, cake fertilizer, etc. can be applied. Before flowering in summer, it is better to apply fertilizer with more phosphorus and potassium content, and fertilization is generally carried out after weeding and loosening the soil.

Precautions: The day before fertilization, the soil should be loosened, which is conducive to the absorption of nutrients by plants and achieves the best fertilizer effect; Water the next day after fertilization to avoid fertilizer accumulation in the soil and cause fertilizer damage.

Fertilization needs to keep these time points in mind: fertilize after the beginning of spring, do not apply after the autumn equinox; Fertilize the buds now, but not when the buds crack; Apply fertilizer on sunny days before the rain, but not after the rain; Fertilize the potting soil when it is dry, and do not apply it when it is wet; Thin fertilizer is applied frequently, and thick fertilizer is not applied; Fertilize before and after flowering, and do not apply during flowering; Fertilize in the morning and evening, and do not apply at noon; Strong seedlings are applied more, and weak seedlings are not applied.

1. Apply plantar fertilizer.

In the process of maintenance, gardenia grows slowly, the branches are thin, and frequent top dressing is required, indicating that the bottom fertilizer is insufficient during planting. Before planting gardenias, organic fertilizer (rotted animal manure, cake fertilizer) is added to the soil and mixed evenly with the soil.

2. Apply slow-release fertilizer.

In fact, most families raise flowers, the number of fertilization is small, and even not often take care of it, in order to facilitate and save trouble, agricultural scientists have developed a lazy fertilizer - slow-release fertilizer. If the fertilizer is applied in a pot, the fertility in the fertilizer will be released slowly, so there is no need to worry about the damage to the plant if you apply too much fertilizer. However, fertilization is stopped after October and during flowering.

3. Top dressing. 4 October, except for the flowering period, top dressing once a month. Potassium dihydrogen phosphate was sprayed weekly in April, until most of the branches of the whole gardenia bud appeared.

Watering the roots twice with potassium dihydrogen phosphate after budding can enhance the stress resistance of the plant and promote the large and fragrant flowers of the plant. But as soon as the buds crack and show white, the fertilization should be stopped.

4. Change pots and fertilize.

If the pot is changed, the plant should be placed in a cool place to pot, and then fertilized after the slow potting period.

5. Precautions.

The day before fertilization, the soil should be loosened, which is conducive to the absorption of nutrients by plants and achieves the best fertilizer effect; Water the next day after fertilization to avoid fertilizer accumulation in the soil and cause fertilizer damage.

Growing environment

It can also tolerate shade and shade, and the leaf color is dark green under shade conditions, but the flowering is slightly poor; It prefers warm and humid climates, is heat-tolerant and slightly cold-tolerant (-3), prefers fertile, well-drained, acidic light clay loam, and is also resistant to drought and barrenness, but the plants are prone to aging. Strong resistance to sulfur dioxide. The tillering power and germination power are strong, and it is resistant to pruning and renewal.

Gardenia fertilization method.

1. Gardenia should be applied to cooked soybean cakes, sesame sauce residues, peanut bran and other fertilizers, which can be acidic after fermentation and rotting, but must be applied with thin fertilizer, avoid thick fertilizer, raw fertilizer, and do not apply fertilizer during the hibernation period

Raise gardenias, fertilize with this method, the leaves are green, the buds are many, and the flowers are beautiful!

Gardenia is not a very fattening flower, but because it grows vigorously and is limited by the nutrients of potting soil, it needs to be reasonably supplemented with fertilizer during the growth period. Apply rotten human manure or cake fertilizer every 10 days or so, stop watering 1 day before fertilization, and water once at the same time on the day of fertilization. Fertilization will be stopped from mid-September.

For adult plants, apply sesame paste residue once in mid-June and mid-August, two at a time, and mix well with the topsoil after crushing.

Apply base fertilizer: Apply a sufficient amount of base fertilizer to the soil before potting the gardenia to improve soil fertility. Slow-release fertilizer:

Before flowering, apply slow-release fertilizer to the soil. Timely top dressing: From April to October every year, gardenia is topdressed with fertilizers rich in nitrogen, phosphorus and potassium.

Precautions: When fertilizing, loosen the soil for the plants in advance.

1. Apply base fertilizer

In the process of maintaining gardenias, it is necessary to apply sufficient amount of bottom fertilizer to the soil before the plant is potted, so as to improve soil fertility and meet the nutrient needs of gardenia growth and development.

2. Apply slow-release fertilizer.

After October every year, as well as during the flowering period, it is necessary to stop fertilization, but before flowering, you can apply slow-release fertilizer with a long fertilizer effect to the soil, which can avoid root burning, yellow leaves, and poor growth due to excessive fertilization.

3. Timely top dressing

From April to October each year, gardenia is topped with nitrogen, phosphorus, potassium fertilizer, and with the use of trace element fertilizer, generally sprayed with potassium dihydrogen phosphate on the leaves once a week, and phosphorus and potassium fertilizer is added after budding, so as to improve the stress resistance of the plant and promote the large and fragrant flowers.

4. Precautions

When fertilizing gardenias, loosen the soil for the plants one day in advance, which is conducive to better absorption of nutrients by the root system, promote the growth of the plant and promote the growth of the plant and health, and water once the next day after fertilization, so as to avoid the accumulation of fertilizer in the soil and the occurrence of fertilizer damage.
