The latest planting method of fragrant snowball

Fragrant snowball, also known as courtyard mustard, small white flower, jade butterfly ball, etc., is a perennial herb of Cruciferae, the base of which is Lignified, but the cultivated ones are not lignified, creeping, fragrant and pleasant, and suitable for planting on the wall edge of the rock garden, potted plants and ground quilts, etc. let's take a look at the planting method of fragrant snowballs.

Growth habits of fragrant Snowball

Xiangxueqiu originated in Europe and West Asia, like cold and cool, avoid hot, require sufficient sunshine, slightly shady, suitable for loose soil, avoid waterlogging, more resistant to drought and barren. Like cold climate, avoid extreme heat, frost and cold resistance. Like the drier air environment, overcast and rainy days are too long, easy to be infected by bacteria. For fear of rain, keep the leaves dry at night, and the optimum air relative humidity is 40-60%.

The breeding method of fragrant Snowball

The propagation method of fragrant snowball can be propagated by seeds or cuttings, but it is generally propagated with seeds. In the north, it is mostly sown in spring and sowed in March in the greenhouse. Fragrant snowball seeds germinated faster and emerged neatly than ordinary flower seeds, and the optimum temperature for germination was 20 ℃. They emerged in about 5 days, planted in pots when 3 to 4 true leaves, and blossomed in June. When it is hot in summer, it grows poorly and blossoms rarely. At this time, it is necessary to cut off the flowers that have already opened, strengthen the management of fertilizer and water, and bloom again in autumn. Most of the plants in North China and South China are sown in autumn, overwintering in cold bed protected areas, potting or planting in March of the following year, and flowering in April.

Planting method of fragrant Snowball

1. Matrix: the substrate for the upper basin of fragrant snowballs can choose one of the following, vegetable garden soil: slag = 3:1, or garden soil: medium coarse river sand: sawdust (slag) = 4:1:2, or one of paddy soil, pond mud, rotten leaf soil, or peat: perlite: ceramsite = 2:2:1, or peat: slag: ceramsite = 2:2:1, or sawdust: vermiculite: medium coarse river sand = 2:2:1, pour once after basin And keep it in a shady environment for a week.

2. Install the basin: when installing the basin, the fragrant snowball seedlings first put a coarse-grained matrix or ceramsite 2cm thick at the bottom of the basin as a filter layer, sprinkle a layer of fully rotten organic fertilizer as base fertilizer with a thickness of about 1cm, then cover it with a substrate, which is about 1cm thick, and then put in the plant to separate the fertilizer from the root system and avoid root burning.

3. Transplanting: when transplanting fragrant snowball seedlings, first dig the planting hole, sprinkle a layer of organic fertilizer at the bottom of the planting hole as the base fertilizer (base fertilizer), the thickness is about 46.6 cm, and then cover a layer of soil and put it into the seedlings to separate the fertilizer from the root system and avoid burning roots. After putting it into the seedling, backfill the soil, cover the root system, and trample the soil with your feet and water it once.

Planting Management of fragrant Snowball

1. Temperature: Xiangxueqiu is not very strict on winter temperature, as long as it can survive the winter safely without frost, it dies when the temperature is more than 30 ℃ in late spring and early summer, and the most suitable growth temperature is 15-25 ℃. In late autumn, winter and early spring, because the temperature is not very high, it is necessary to give it direct sunlight to facilitate its photosynthesis and the formation of flower buds, flowering and fruiting. If you encounter hot weather in summer, you need to shield it from about 50% of the sun.

2. Fertilizer and water: like other grass flowers, Xiangxueqiu requires more fertilizer and water, but is most afraid of random fertilization, concentrated fertilizer and partial application of nitrogen, phosphorus and potash fertilizer. It is required to follow the two principles of frequent application of light fertilizer, less and more times, complete nutrition and wet between dry and dry, dry and thoroughly watered, and after fertilization, leaves and flowers should be kept dry at night.

3. Autumn: after the sowing seedlings of fragrant snowballs have been restored for a period of time, it is necessary to quickly keep up with the fertilizer and water management. The fertilizer and water management is cycled according to the order of → → clear water → clear water, the interval period is about 1-3 days, the interval period is shorter in sunny days or high temperature, and longer or no watering in rainy days or low temperature periods.

4. Winter: although the fragrant snowball continues to grow in winter, the low temperature will slow down its growth rate, do not require much fertilizer and water, and even control fertilizer and water. Fertilizer and water management according to Huabao → clear water → clear water → Huabao → clear water → clear water cycle, the interval period is about 4-7 days. Watering time is arranged as far as possible when the temperature is high at noon on a sunny day.

5. Spring: the growth of fragrant snowball recovers rapidly after the temperature rises in spring, and gradually enters the flower bud differentiation stage and flowering stage, which requires a lot of fertilizer and water. Fertilizer and water management cycle according to the order of Huabao → clear water → Huabao → clear water, the interval period is about 2-4 days. After entering the fruiting stage, stop the supply of fertilizer.

6. Heart picking: fragrant snowballs generally pick the heart twice before flowering to promote the germination of more flowering branches. One to two weeks after potting, or when the seedling is 6-10 cm tall and has more than six leaves, remove the top tip and retain the lower 3-4 leaves to promote branches. After 3-5 weeks of the first coring, or when the lateral branch grows to 6-8 cm long, the second coring is performed, that is, the top tip of the lateral branch is removed and the 4 leaves under the lateral branch are retained.
