1. About watering flowers

① Residual tea is used to water flowers, which can not only maintain soil moisture, but also add nutrients such as nitrogen to plants. However, it should be poured regularly and appropriately according to the humidity of the flowerpot, rather than pouring with the residual tea

② The deteriorated milk is used to water the flowers. After the milk is deteriorated, water is added to water the flowers, which is beneficial to the growth of flowers. But it needs more water to make it more diluted. Unfermented milk should not be watered because it produces a lot of heat during fermentation and will "burn" roots (rotten roots)

③ Watering flowers with cold boiled water can make flowers and trees luxuriant and colorful, and promote their early flowering. If it is used to water asparagus, its branches and leaves can develop laterally, dwarf and dense

④ Water the flowers with warm water. It's cold in winter. It's better to water the flowers with warm water. It is best to place the water indoors and pour it when it is close to the room temperature. It would be better if the water temperature could reach 35 ℃ before pouring

⑤ Rice washing water is often used to water flowers such as Milan, which can make its branches and leaves lush and bright colors

2. Five methods of fertilization

(1) Maifan stone fertilizer, sprinkle a layer of Maifan stone particles in the flower pot, which can promote the growth of flowers and prolong the flowering period

(2) Crushing eggshell fertilizer, crushing eggshell and burying it in the flowerpot, is a good fertilizer, which can make the potted flowers grow luxuriantly, with colorful leaves and flowers

(3) Cook a small amount of soybeans and set aside. Each pot of flowers goes through three holes and puts in 3-5 cooked soybeans, 2-3cm deep, without damaging the flower roots, and is covered with soil as usual

(4) Roast and smash the pig bones and fish bones that are ready to be discarded on weekdays, and put them on the bottom or surface of the basin

(5) Water the flowers with rice washing water. The rice washing water contains trace elements such as nitrogen, phosphorus and potassium, which is both compound fertilizer and mild fertilizer. It does not hurt the flower roots. It can be used at any time as long as the basin soil is not soaked

3. Collect organic fertilizer for potted flowers

Chemical fertilizer should not be commonly used in family flower cultivation. The main fertilizers such as nitrogen, phosphorus and potassium needed to cultivate flowers can be collected in daily life. For example, moldy and inedible waste peanuts, beans, melon seeds and cereals are nitrogen-containing fertilizers, which can promote the vigorous growth of flowers and trees by fermenting as base fertilizer or soaking into solution as topdressing; Fish bones, broken bones, chicken feathers, eggshells and people's cut nails and hair are rich in phosphorus. Add some water into the old culture soil, put it in plastic bags and put it in the corner. After a period of decay, it can become excellent organic fertilizer. If these wastes are soaked into a solution and then topdressing, the flowers of domestic potted flowers can be bright in color and have many fruits. In addition, fermented rice washing water, water replaced by raw bean sprouts, plant ash water, rainwater and wastewater in fish tanks all contain a certain amount of nitrogen, phosphorus and potassium, which will promote the growth and development of flowers and trees as long as it is used in an appropriate amount

4. Pericarp can neutralize alkaline basin soil

Some flowers in the south are not easy to survive or bloom in potted plants in the north, because the basin soil is too alkaline. There are many ways to neutralize alkaline soil. This method is to soak the peeled apple skin and apple core in cold water. Often water the flowerpot with this water, which can gradually reduce the alkalinity of the basin soil

5. Flower disease prevention

In early spring, all kinds of flowers will enter the vigorous growth season. At this time, spray 1-3 times of 1% Bordeaux liquid on the leaf surface and back to prevent diseases. The method of preparing 1 ml of copper solution after pulverization: 1 ml of Bordeaux sulfuric acid; Then use 1g quicklime, pulverize it with a few drops of water, and then add 50ml water to filter the residue; Pour the two solutions into the same container at the same time and mix well. Finally, the transparent Bordeaux liquid is sky blue

6. Six methods of killing insects and ants in flower pots

(1) When there are small flying insects in the flower pot, three or four cotton cuttings (cotton sticks) can be used to dip dichlorvos fully, so as not to drop, and then insert the handle end into the basin soil around the plant, and the flying insects can be eliminated

(2) Washing powder: dissolve a tablespoon of washing powder in 4 liters of water and spray flowers and leaves every two weeks to completely eliminate white flies and bacteria

(3) Milk: mix 4 cups of flour and half a cup of milk into 20 liters of water, mix it, filter it with gauze and spray it on the flowers and leaves, which can kill ticks and their eggs

(4) Beer: pour the beer into a shallow pot under the soil of the flower pot, and the snail will be drowned if it climbs in

(5) Garlic: mash a big garlic and mix it with a tablespoon of pepper into half a liter of water. After an hour, spray it on the flowers and leaves to prevent the invasion of rats

(6) When ants appear in the flowerpot, soak the cigarette butts and cut tobacco in hot water for one or two days. When the water turns dark brown, sprinkle some water on the flower stems and leaves, and pour the rest into the flowerpot after dilution, and the ants can be eliminated

7. Three methods of fresh-keeping fresh flowers

① The rose flower is moxibustion with fire at its cut, and then inserted into the bottle. The autumn chrysanthemum is painted with a little menthol crystal at its cut. Chrysanthemum in the clear water for raising chrysanthemum, add a small amount of urea or soil leaching solution (the solution formed by adding water and stirring and filtering fertilizer soil), which can make the chrysanthemum in the bottle wither for 30 days, which can be extended by more than 10 days compared with ordinary clear water. White orchids are wrapped in wet cloth at night and opened during the day, which can delay the withering time of flowers by 2-3 days

② When going far away, take out the flowers in the bottle and put them in the fruit and vegetable box of the refrigerator for preservation, which can keep them from withering for a long time. When you come back, take them out and put them in the vase, which can be lifelike

③ Dissolving aspirin in water can prolong the flowering time of bottled flowers

8. Adjust flowering time

Put the flower seeds, plant bulbous roots or cuttings into plastic bags, and then put them into the refrigerator. Take them out to plant seeds at an appropriate time, and the flowering time can be adjusted arbitrarily

9. Frozen potted flower resuscitation method

In spring and cold season, potted flowers will freeze outdoors. In this case, the potted flowers can be quickly wrapped in three layers with waste newspapers with strong water absorption. When wrapping, pay attention not to damage the branches and leaves of the potted flowers and avoid direct sunlight. Let it stand for a day so that the temperature of the potted flowers gradually rises. After this treatment, the frozen potted flowers can recover

10. Clivia summer method

In midsummer, the temperature is often above 30 ℃, which is extremely unfavorable to the growth of Clivia. Therefore, shed cooling is commonly used. You can also bury the Clivia with the basin in the sand (bury the basin), and then sprinkle water on the sand every morning and evening. In this way, the basin soil can be kept wet, and more importantly, the endothermic effect of water evaporation in the sand can be used to achieve the purpose of cooling. 　

11. Hydrangea turns blue

When a rusty iron nail is nailed into the root of Hydrangea, the hydrangea will obviously turn blue

12. Ash soil cleaning method on plants

When many families clean, whether in winter or in midsummer, they usually wash the potted flowers under the tap, which often affects the growth of plants due to sudden changes in temperature. If it is a foliage plant, you can dip in water and clean it piece by piece along the flower branches and leaf veins. Other plants can be washed with a watering can

13. Flower raising deodorization method

Indoor flowers will give off a bad smell if they use fermented solution as fertilizer. If the orange peel is put into the fertilizer solution, the smell will be eliminated. At the same time, orange peel itself is also a good fertilizer

14. Four methods of self-made insecticides

① Take 200 grams of green onions, cut them up and soak them in 10 liters of water for one day and night. After filtering, they are used to spray the affected plants several times a day for five consecutive days

② 200-300g garlic, mash and take juice, add 10 liters of water to dilute, and immediately spray the plant

③ 400 grams of tobacco powder, soak it in 10 liters of water for two days and nights, filter out the tobacco powder, add 10 liters of water and 20-30 grams of soap powder, mix well and spray the affected flowers and trees

④ 10 liters of water and 3 kg of plant ash. After soaking for 3 days and nights, the plants can be sprayed

15. Weed eradication method

Weeds have strong fecundity. Weeds in the courtyard have just been uprooted and grow everywhere in a few days. In this case, do not pour out the salt water normally used to pickle duck eggs or pickles. In the season of weed prosperity, pour the salt water on the weeds three or four times to stop the growth of weeds. In addition, the water for boiling potatoes can also remove weeds in the courtyard or aisle. Then, it is also very effective to use bleach water to weed. The method is: sprinkle water on the ground to be weeded to make the land wet. After 24 hours, pour it with bleach water< span>
