Geranium sowing method, geranium planting points

Why is autumn suitable for sowing and planting? Autumn and winter grow roots without stopping.

Geranium is one of the most popular flowers, it likes cold climate, the suitable growth temperature is 5 to 25, the plant enters a semi-dormant state in the summer high temperature period, and the cold area can overwinter with a little protection in winter. It likes to grow in a sunny environment, is resistant to dryness, avoids water, requires loose and well-drained cultivation medium, and is rich in organic matter. Geraniums are best sown from late winter to early spring, and bloom throughout summer.

If sown in late summer, the overwintering temperature remains above 5 for spring flowering.

The production of high-quality geraniums is the most basic requirement in the geranium market, and in the cultivation of geraniums, pH value and the application of plant growth regulators are two very critical factors, if growers can grasp these two points, they will be able to produce better quality geranium products for less money.

1. Research on the appropriate pH value.

In general, the pH recommended for the best growth of geraniums is very consistent. During these years, the recommended pH for horseshoe geraniums is between to and for ivy leaf geraniums, but according to the latest research by researchers at Purdue University in the United States, these recommended pH values are not very accurate.

If the pH of the medium is initially low, the pH of the medium may be reduced to in the subsequent growing season of the geraniums. At low pH levels, geraniums do not grow well and end up with a dwarf geranium. Therefore, in order to get the ideal geranium, the pH of the medium should be kept between for both horseshoe geraniums and ivy-leaf geraniums.

Doing so provides an ideal growing condition for geraniums, and also maximizes the growth potential of geraniums and breeds the best geraniums.

It should also be noted that if the pH of the water is around the limit, it is advisable for the grower not to make any changes at this time, as neutral water can compensate for the effect of geraniums on reducing the pH of the medium.

2. Limit the use of plant growth regulators.

When growing geraniums, avoid using too many plant growth regulators. Because after use, these chemicals that remain on the plant can still have an effect on the plant. At **, the plant looks good on the surface in the pot, but in fact, the customer will only buy back a short, stunted geranium, which will only bring the customer an unpleasant planting experience.

Therefore, it is best to use plant growth regulators only as recommended.

In addition, focusing on other cultivation practices can also help promote geranium growth, such as the correct use of water, temperature and fertilizers, which will help reduce the need for plant growth regulators in geraniums. This not only allows customers to buy good geraniums, but also saves growers money on chemicals, which is also very meaningful for growers. By reducing the use of plant growth regulators, growers can produce better geraniums.

1. Soil. Loose, breathable soil should be used. Cultivation soil can be mixed with humus remanipulation, peat, perlite and organic fertilizer. It is better to turn the pot once in the fall.

2. Watering. Watering should be moderate, spring and autumn are the peak season. At this time, sufficient moisture should be maintained, and the potting soil should be in a moist state, but no water should be produced; Reduce the amount of watering when the temperature is low; If there are many rainy seasons, drainage measures should be taken to avoid root rot caused by stagnant water, and should be placed in a dry and ventilated place; In winter, the indoor temperature is much lower, so you should water less.

3. Temperature. The suitable temperature for the growth of geraniums is 15-25. It is best to control the indoor temperature at about 10 and not lower than 3.

It is very cold when it is below this temperature, and some varieties can accept low temperatures of 0. The maximum temperature must not exceed 35. Once it enters a high-temperature environment, it will enter a semi-dormant state.

Keep a ventilated environment as much as possible and avoid a stuffy environment.

Fourth, light. Geraniums need plenty of sunlight, but shade should be taken when the sun is too strong in summer. In other seasons, it can be exposed to sunlight.

If there is not enough sunlight, it will not bloom. When flowering, it should be kept out of direct sunlight, moved indoors, and put back in a sunny place when the flowers are gone. Turn the pot as far as possible so that the light on the leaves is more even.

Flowering period from May to June, except for midsummer dormancy, if the environment is suitable, it can continue to bloom. It likes cold, but it is also not cold-tolerant. Avoid high temperatures, like sunshine, like well-drained fertile loam; It is not resistant to water and moisture, and it is easy to grow if the humidity is too high, and it is slightly resistant to drought.

The suitable temperature for growth is about 15 degrees Celsius during the day and not less than 5 degrees Celsius at night. In summer, dormant or semi-dormant should be placed in semi-shade and moisture should be controlled.

In autumn and winter, it grows well in full-day and half-day locations, and is also suitable as a flower bed plant. If it is placed indoors, there must be scattered light, otherwise the flowers and leaves will fall quickly.

Geranium planting needs to use the end of the fertilizer, slow release fertilizer, so that it will grow better!

Sowing and propagating:

From practice, it is known that the flower life of geranium plants bred by sowing is longer than that of cuttings, and the number of flowers is large, which is favored by scenic spot users, especially the hybrid generation, which shows its advantages. According to the characteristics of geraniums that are not tolerant to heat and can grow robustly in a cold environment, combined with the needs of the market and the requirements of users, in recent years, producers have mostly used sowing seedlings to bloom on New Year's Day and Spring Festival to achieve greater benefits.

1.During the New Year's Day, flowering and cultivating strong seedlings make their root system developed, and the damage to the root system should be minimized when transplanting, and the seedling period should be minimized. Choose early-growing varieties, such as F1 multi-flower series, with a growth period of 80 to 90 days; Early sowing date, generally in early September; Strictly select places with ventilation, light and rainproof facilities for sowing and seedling raising; According to the climatic characteristics of South China, the weather begins to cool after mid-October, and it is safer to place open field cultivation at this time.

2.Flowering during the Spring Festival Sowing from late September to early October; The sowing and seedling environment should also be ventilated, cool, rainproof and light; The use of seedling cups is ideal, which is conducive to improving the survival rate and reducing costs.
