No flowering reason: the soil is not suitable

Gardenia like acidic soil. The land in the north is alkaline. Over time, the soil will be affected. Due to lack of nutrients, gardenia will not bloom naturally

Solution:

When watering, you can add some ferrous sulfate to improve the soil. You can often apply 10% alum fertilizer as topdressing. You can also ferment the acidic fruit skins such as pineapple, orange and grapefruit and put them in the soil

Reason for non flowering: less fertilization

Gardenia likes fertilizer. If the fertilizer is insufficient, it will lead to poor plant growth, no nutrient supply and flowering

Solution:

1. During the growth period of gardenia, apply more rotten cake fertilizer once every 10 days. From April, spray potassium dihydrogen phosphate solution once a week at the concentration of 1:2000 until flower buds appear on most branches of the whole gardenia

2. After budding, the roots are watered with potassium dihydrogen phosphate twice to enhance the stress resistance of the plant and promote the plant to blossom larger and more fragrant. If you find that the flower bud is cracked and white, you should stop fertilizing

Rose

There are many kinds of roses. When they bloom, the flowers are big and colorful, so many people choose to cultivate roses. But many flower friends reflect that the roses they cultivate only grow branches without flowering. What's the matter

Reason for non flowering: insufficient soil fertility

If the soil for planting rose is poor or there is no soil change for a long time, it will lead to insufficient soil fertility and lack of nutrition, especially the lack of phosphorus and potassium fertilizer, which will affect flower bud differentiation and impossible to bloom

Solution:

1. Fertilize more. It's best to fertilize when the rose is dormant from January to February, so that the fertilizer can gradually ferment into fertilizer liquid and penetrate into the roots with watering

2. May is the vigorous growth period of rose, and fertilization can be carried out once in about 10 days. Cake fertilizer or rotten and fermented chicken manure can be used for fertilization according to the ratio of 3:7, and fertilization will be stopped in November

Reason for non flowering: long-term non pruning

If the rose is not pruned for a long time, it will lead to too many branches, scattered nutrients and reduced nutrients for flower buds, so that flower buds cannot form

Solution:

1. Prune the rose once a year around December, and cut off the side branches, sick branches and concentric branches. After flowering in May, cut off 2 / 3 or 1 / 2 of the flowering branches, so that it has the opportunity to grow flower buds again

2. In order to make the flowers bloom big, you can sparse the buds of roses, pick some buds, concentrate nutrition and prolong the flowering period

Jasmine

Jasmine flower is white and fragrant. It is a popular flower. It can bloom continuously for several months in a suitable growth environment. But many flower friends say that their jasmine flowers are luxuriant, but they don't bloom or bloom very little. What's the problem

Reason for non flowering: insufficient light

Jasmine likes sunshine very much. If the light is insufficient, it will lead to the crazy growth of leaves, absorb all the nutrients, and the flowers will not open without nutrition

Solution:

Place the jasmine in a sunny place, such as a courtyard or a south facing balcony or windowsill, to ensure that it can receive about 10 hours of light every day, so that the Jasmine can grow and bud until it blooms

Reason for non flowering: lack of fertilizer

If Jasmine receives enough light, it is basically lack of phosphorus and potassium fertilizer

Solution:

1. Before Jasmine bud pregnancy, less nitrogen fertilizer and more phosphorus and potassium fertilizer can be applied. Rotten bone meal and chicken manure can be used as base fertilizer, followed by topdressing with quick acting phosphorus and potassium fertilizer or alum fertilizer water, and watered once a week to promote plant bud pregnancy

2. After Jasmine blooms, it is necessary to change the pots and soil in time to maintain sufficient nutrition in the pots and soil, improve the condition of non flowering, and make Jasmine bloom big and fragrant

Longevity flower

The flowering period of Changshou flower is from December to May of the next year. During this period, as long as it is properly maintained, the plant will continue to produce beautiful flowers

Reason for not flowering: wrong light

Too strong or too weak light will affect the flowering of plants. If the light is too strong, the plant is easy to wilt and affect the growth and development; Uneven exposure to light will lead to plant deformity and affect flowering

Solution:

1. Put the longevity flower in the light receiving place of the balcony, shade it properly in summer, and normal light in other times to ensure that it receives more than 4 hours of light every day

2. Often rotate the direction of the flowerpot to make the plant receive light evenly. Rotate the flowerpot 180 degrees in about half a month

Reason for non flowering: too little fertilization

Longevity flowers like fertilizer. The flowering period can be as long as 6 months, so they need a lot of nutrients. In the absence of fertilizer, the flower bud differentiation of Changshou flower is relatively slow. Even if the plant has many branches, it will be difficult to ensure flowering due to lack of nutrition

Solution:

1. From November to October of the next year, it is basically the late stage of flower bud differentiation and full flowering of Changshou flower, which is also the time when plants accumulate nutrients, and there is a great demand for fertilizer. Fertilizer containing phosphorus, such as fishy manure and calcium superphosphate, can be applied once a week to promote the differentiation of flower buds

2. Thin nitrogen, phosphorus and potassium fertilizer or 0.2% potassium dihydrogen phosphate solution can be applied once a month to prevent the flowers from becoming smaller and lighter in late flowering due to lack of fertilizer

Camellia

There are many varieties of Camellia, including single and double petals. The flower colors also include red, purple, white and yellow, and even colored striped camellia. Its flowering period is very long, from October to May of the next year, and its full flowering period is usually from January to March

Reason for non flowering: wrong humidity

If the camellia is short of water, it will lead to poor plant growth, so that the camellia will not bear flower buds, even if there are flower buds, it will not bloom

Solution:

1. On sunny days, water once every 3-5 days to keep the basin soil moist. If the flowerpot of camellia is relatively large, it can be watered once every 5-7 days

2. After 10 a.m. on a sunny day, spray water on the Camellia plants to maintain air humidity

Cause of non flowering: diseases and insect pests

The flower bud stage of camellia is vulnerable to diseases and insect pests, such as aphids and rust ticks. These pests will erode the flower bud and affect the flowering of Camellia

Solution:

1. If aphids are found on Camellia, they can be sprayed on the plant with a solution of 40% Omethoate EC 1000 times, so as to kill the aphids

2. If rust ticks appear, you can use 50g of washing powder, 10ml of diesel oil and 10kg of water to stir evenly, and then spray the solution on the camellia plant to eliminate rust ticks
