When does the lotus usually sow and blossom? How do you plant seeds? What if the leaves turn yellow?

Nasturtium is a plant belonging to the family Nasturtium, also known as drought lotus, cold lotus, golden lotus, golden lotus, red cardinal So when does it usually sow and bloom? How to plant seeds? What if the leaves turn yellow? According to different regions and climates, the seed sowing of nasturtium can be divided into spring sowing, autumn sowing and winter sowing according to the flower base in suqian, jiangsu province.

When do nasturtiums usually sow and bloom?

Sowing:

1, spring sowing (East China): summer high temperature is not suitable for the growth of nasturtium, so spring sowing should be early. Germination can occur from early February to early March, buds appear 30~35 days after germination, and flowers 40~45 days after germination. The characteristics of spring-sown nasturtium are broad leaves, slender stem nodes, fewer flowers than autumn-sown, shorter flowering period of single flower, fewer and smaller seeds. Spring sowing has a short growth cycle, so it is more suitable for beginners.

2. Autumn sowing (East China): Autumn sowing of nasturtium is carried out from late September to early October, and February to March of the following year is the full bloom. The autumn-sown nasturtium is characterized by thick leaves, thick branches, compact plant type, short stem nodes, many flowers, long flowering period of single flower and plump seeds. Autumn sowing because of the long growth cycle, so more test the patience of flower friends and planting skills.

Flowering:

Flowers solitary or 2 - 3 in cymes, 5 petals, sepals 8 - 19, yellow, elliptic-obovate or obovate, petals as long as sepals, narrowly banded.

In the north, it is often cultivated as a biennial flower. Under suitable environmental conditions, it can bloom all year round. A flower can last 8-9 days, and the whole plant can bloom dozens of flowers at the same time. The fragrance is fragrant and the color is gorgeous, which wins people's love.

In southern China, it can be cultivated perennial; in northern China, it is sown in autumn and cultivated in potted rooms. It is used as a spring flower and blooms during New Year's Day and Spring Festival.

The leaves are fat and the flowers are beautiful. The colors are purple, orange, milk yellow, etc. The golden lotus vine stems are intertwined. The leaves are shaped like lotus. When the milk yellow flowers are in full bloom, they are like butterflies flying. It is an important ornamental flower.

How to plant nasturtium seeds?

1, seed treatment: nasturtium because the seed coat is relatively thick, before sowing with warm water (about 40℃) or cold water soak for 12 hours, peel off the seed skin, and then continue to soak for 12 hours, to water does not overflow the seed is appropriate.

2, seed germination: take clean unscented paper towel, fold 6~8 layers, put in a small dish, wet with pure water (wet with paper towel is appropriate), put the soaked seeds in the middle of the paper towel and gently press them, then put the small dish into a transparent food bag and tighten them. Breathe for 15~30 minutes every day.

3, budding sowing: with paper towel germination seeds will generally crack in 2 to 7 days to expose the bud tip, to be 2 mm when the bud tip can be under the soil seedlings. 2~5 days after planting, the cotyledons will break out of the soil, and when the cotyledons are fully unfolded, they can receive full light.

What about yellow nasturtium leaves?

1. Too much watering leads to yellow leaves of nasturtium (yellow water): excessive watering of nasturtium, poor drainage, easy wet rot of roots, light yellow leaves falling off heavy plants wilting death. (If the water in the basin causes the leaves to yellow)

Solution: reduce watering after flowering to prevent branches from growing.

2. Long-term water shortage leads to yellow leaves of nasturtium (drought yellow): leaf tips or edges are withered and dry, old leaves fall off from bottom to top, but new leaves grow normally.

Solution: When watering enough, watering can be thoroughly.

3. Exposure causes yellow leaves of nasturtium (burning yellow): flower leaf tips, leaf margins are withered and dry, and yellow spots appear in the sunny part of leaves.

Solution: Move to the shade.

4. Insufficient sunlight leads to yellow leaves of nasturtium (lack of light yellow): nasturtium placed in semi-shade or shade, it is advisable to have yellow leaves.

Solution: It needs to be placed in sunny conditions to grow well.

5, the temperature is too low to cause yellow leaves of nasturtium: cold wind blowing and heating, air conditioning dry hot air blowing, otherwise it is easy to cause yellow leaves.

Solution: It is best to keep the temperature above 10 ° C, and the lower the temperature, the more control the watering times.

6. Excessive fertilization of nasturtium leads to yellowing of leaves (fat yellow): excessive fertilizer will cause fertilizer damage. Especially when pouring fertilizer solution, it is necessary to prevent the fertilizer solution from splashing on the leaves.

Solution: Put it in a cool and ventilated place, stop fertilizer and water less.

7, nasturtium long-term lack of fertilizer leads to yellow leaves (lack of yellow): the color of young leaves becomes pale, yellow or light green, while the old leaves are relatively normal or gradually turn from green to yellow.

Solution: check basin soil if there is dry phenomenon should change soil, usually thin fertilizer and timely irrigation of some alum water.

8. Diseases and pests cause yellow leaves of nasturtium: If there are spider silk on your nasturtium leaves, or insects hidden in the inner pages of the plant, the yellowing of the leaves must be caused by diseases and pests, and its severity can cause all leaves to die.

Solution: Increase humidity, but also spray mites to kill pesticides.

Attachment: Nasturtium maintenance method

1. The cultivation of nasturtium should be carried out with sandy loam rich in organic matter, PH value 5-6. Fertilization is generally applied every 3-4 weeks during the growth period, and soil should be loosened in time after each fertilization to improve aeration and facilitate root development.

2. Nasturtium is wet and afraid of waterlogging. The soil moisture shall be kept at about 50%. During the growth period, watering shall be carried out with small water frequently. Watering shall be carried out once every 2-3 days in spring and autumn, watering shall be carried out every day in summer, and spraying water on the leaves in the evening to maintain high humidity.

3. Reduce watering after flowering to prevent branches from growing vigorously. If watering is excessive and drainage is not good, roots are easy to be wet and rot, and light leaves fall off and heavy plants wither and die.

4, nasturtium like sufficient sunshine, not tolerant of shade, spring and autumn should be placed in sufficient sunshine cultivation, summer appropriate shade, summer placed in a cool and ventilated place, the north in mid-October into the room, placed in the sun maintenance, room temperature maintained at 10--15℃, appropriate control of fertilizer water. At the same time, the flowers and leaves of nasturtium have strong phototaxis, so they should be changed frequently when cultivated or viewed to make them grow evenly.
