How to fertilize Petunia, Petunia fertilization method / Fertilizer is light rather than thick / thin Fertilizer is the main method.

Flower friends all know that the flowering time of petunia is very long, and its growth rate is relatively ruthless and easy to burst pots, which has a very large impact on the growth of fertilization, not only to pay attention to timely supplement fertilizer, but also to ensure that the fertilizer applied contains the nutrients required by petunia, so how to fertilize petunia? Let's take a look at petunia fertilization methods.

How to fertilize petunias

Different growth stages, petunia needs different nutrients, such as growth period it mainly branches and leaves development, this time should be dominated by nitrogen fertilizer; and before the arrival of flowering need to increase phosphorus and potassium fertilizer, it can ensure more colorful flowers, but also can make flowering time extended, the following is the fertilization skills of each growth stage.

Petunia fertilization method

1. Seedling cultivation period

Just planted petunia, in the growth of new buds, cotyledons since, you can start fertilization, this time is far from the flowering season, so fertilizer is generally based on nitrogen fertilizer, to ensure that the fertilizer contains iron and other elements, can avoid yellowing leaves. Because seedling stage its rhizome is relatively small, so the demand fertilizer is not much, pay attention to apply thin fertilizer.

II. Growth period

After the seedling stage, petunias will enter the vigorous growth period. How will petunias be fertilized at this time? Generally based on organic fertilizer, it can ensure that nutrition is more comprehensive, but also can use farm manure, cake fertilizer, etc., must use decomposed fertilizer, avoid applying raw fertilizer and causing pests.

III. Before flowering

If the breeding method of petunia is correct, it will enter flowering at the right temperature. At this time, it is necessary to increase the application amount of phosphorus and potassium fertilizer, which can promote the formation of flower buds and make the number of flowers more. However, the fertilizer must not be excessive, otherwise it will cause excessive concentration of root fermentation and heat generation and root burning.

Petunia fertilizer considerations

1. Apply enough base fertilizer when planting: To meet the needs of seedlings entering the growth period faster after planting, it is necessary to apply enough base fertilizer at the time of planting. Common base fertilizers include organic fertilizer, chicken manure fertilizer, cake fertilizer, bone meal, etc., which require a longer fertilizer effect and can ensure a longer fertilizer effect of the soil.

2. Water-soluble fertilizer is the main fertilizer at flowering stage: at flowering stage, water-soluble fertilizer should be used as the main fertilizer. The method is to mix fertilizer with water according to a certain proportion and then irrigate it in the soil. The dosage can refer to the product description. This can make the roots absorb nutrients quickly, thus sprouting more buds.

Petunia we are very familiar with, we may not care about morning glory, because morning glory and weeds together, we will mistake it for weeds, we will not even look at it a few eyes, but flowering morning glory, vibrant, colorful, let people notice at once, their flowers are like a small lama in general, like telling people I can also be very dazzling, really very likable, breeding people are also many, so how to fertilize petunia? Here is a brief introduction to the fertilization method of petunia.

How to fertilize petunias

Petunia is also a fertile plant, which needs sufficient fertilizer to maintain a large number of flowers for a long time. The daily method of fertilization of petunia is to mix a large amount of chicken feces at the bottom of the medium for base fertilizer, and then cover it with a layer of slow release fertilizer such as Australian green. Usually every watering is mixed with about 2000 times liquid fertilizer. If it is cloudy and rainy, reduce the concentration and spray it directly on the leaves, but pay attention to avoid direct sunlight after fertilization and the leaves are still wet after sunset (easy to get sick).

Fertilization of Petunia

Fertilization is very important for strong roots and luxuriant branches and leaves. Compound fertilizer (20-5-30) and calcium and magnesium (13-2-13-6Ca-3Mg) are applied alternately. EC values of the matrix were maintained at 110~112. For liana petunia, the fertilizer concentration should be increased from 100~150mg/kg to 200mg/kg, and the EC value of medium should be 1.2~1.5. Stripe yellowing of leaves is often caused by boron deficiency and calcium deficiency, which can be remedied by compound fertilizer of boron 40~60mg/kg or calcium.

How to fertilize petunias? Do you know all the fertilization methods of petunia? Next, we will introduce you to the fertilization method of Petunia in detail by Xiaobian.

Fertilization of Petunia:

1. Seedling stage

Sowing does not require any fertilizer, but fertilizer may affect the germination rate. After budding, the cotyledons can be applied with light fertilizer when they are unfolded. Dilute the concentration in the product description by more than double the amount of water. At this stage, iron fertilizer should be used, and seedlings are prone to iron deficiency and yellowing. Seedlings must be light, need a small amount of fertilizer, roots and tender, remember oh.

II. Rapid growth period

Nursery box or hole tray can be full after the false planting, false planting medium to add a small amount of base fertilizer, organic fertilizer or chemical fertilizer, comprehensive nutrition is better. Organic fertilizer has farm manure, cake fertilizer, chicken manure, kitchen waste retting fertilizer, etc. can be. Need to pay attention to is, must be retting cooked, otherwise it will continue to ferment fever and burn roots, and easy to live insects. Chemical fertilizer with compound fertilizer or slow release fertilizer, controlled release fertilizer, the latter two are better.

After planting, it enters the rapid growth period, and the base fertilizer should be sufficient to meet the needs of seedling growth and flowering. And topdressing, of course. The base fertilizer is still organic fertilizer and inorganic fertilizer. Chicken manure, cake fertilizer, bone meal, and other organic fertilizers available in the market, plus slow release fertilizer more comprehensive. Only organic fertilizer or slow-release fertilizer theory is also OK, depending on their choice of medium fertilizer content and add it as appropriate.

III. Flowering period

By topping the pot shape, the temperature is right can see flowers. This period began to increase the amount of phosphate fertilizer to promote the formation and opening of flower buds. Because petunias bloom so much, it's especially important to get enough fertilizer.

Water-soluble fertilizer was mainly used in flowering period. Water-soluble fertilizer usage, personal watering like to water the soil, so that the root absorption. Wet leaves are easy to breed bacteria, especially during flowering, flowers stained with fertilizer water are also easy to produce spots.

The purpose of using fertilizer is to supplement according to the needs of plant growth stage, rather light, not thick, thin fertilizer and frequent application. Of course, it is not necessary to add fertilizer every time watering, especially agricultural fertilizer with low purity. It is better to irrigate with clean water the next day after fertilizer or when watering again. Too much fertilizer will burn the roots, or accelerate the aging of the roots, so it should be appropriate.
