Time is like a flower-- falling in love with Platycodon grandiflorum

Sowing Platycodon grandiflorum is actually very simple, as long as 100 days to see flowers, there is no garden and no longer worry about the rose.

It is said that Platycodon grandiflorum looks bad, after three sowing and two blossoms, the budding rate is 90%, the flowering rate is 80%, and it blossoms as soon as 80 days. Summarize the method of planting Platycodon grandiflorum indoors in Beijing, which directly makes up for the defect of bad rose without garden. Come together.

Planting coordinates: Beijing

Planting location: indoor floating window, open north balcony.

Buy imported pelleted seeds and start sowing on March 6.

Room temperature 18-24 degrees; maximum 40 degrees in sunlight, air humidity 30-60%

Domestic seedling block, into the box, cover, direct exposure

Tip: put the seed in the middle and wet the coating and touch it with a small spoon to expose the seed.

March 20 from the 7th day to the 14th day, 40 seeds, 37 seedlings, very small seedlings, use a magnifying glass to look carefully; start to open the lid for 2 hours every morning and evening, and then increase the lid opening time by 1 hour every day

Tip: a pair of real leaves in front of the sun must be covered with a lid to moisturize, or it may die in one day.

On May 6, four true leaves can be put on the pot.

Loess / decommissioned gentleman's orchid soil (rotten leaf soil) / fine sand 3 _ 3 _ 1% chicken dung, 1% bone meal.

V9 small basin, one in each basin; dry bubble basin, about once every 3-5 days, unfertilized

Tip: later sowing found that a pair of true leaves after spraying Wanwu urea every week, the growth is much faster, four real leaves before the pot is easy to get hurt.

June 2 has begun to strip, as there is no sunshine indoors (there is no south balcony), just put the seedlings on the north balcony, like whatever.

Tip: coincidentally or not, the ones that were put into the north balcony after drawing all blossomed at last, and those without them did not blossom.

June 20 gradually began to blossom, striping to blossom less than a month, indeed because sowing too late they are anxious to blossom, the growth is really too thin.

Tip: there is no need to top before the first flowering, topping will prolong flowering for more than a month, and topping will not easily increase flower branches.

After flowering, only cut off the flower branches, other buds will continue to open, but also will grow more flower branches, each flower blooming for about 2 weeks.

Then start to look at the flowers. They bloom from July to September.

Cut off the whole branch after flowering on August 20, the root will continue to send out lateral buds, but no longer shoot, it may be too late, this batch can only wait until May next year before flowering.

Next year, try to see if the branches that bloom in May will continue to blossom.

Sowing summary of Platycodon grandiflorum:

1. The best time for indoor sowing in Beijing should be around February. It can blossom 100 days after sowing and blossom in May. Because flowering requires high temperature, even if sowing before February, it will blossom after May.

2. Different varieties have different germination time, the fastest is 7 days and the slowest is 28 days.

3. Sowing uses seedling block + seedling box, if the seed is good, the germination rate will be more than 90%, and direct covering and exposure will increase the germination rate and is conducive to the rapid growth of seedlings.

4. as soon as the strips are drawn, they begin to apply phosphorus and potassium fertilizer, which is more favorable for striping, and has more flower branches, and the flower color is better and brighter.

5. There is no need to top before the first flowering, topping can not promote more branches and will delay flowering. If you want to have more than one branch, wait for the second year.

6. One small pot with 10: 10 in the first year has the best effect, and 4 pots can be moved with soil in autumn after flowering, and the basin will burst in the coming year.

7. It is said on the Internet that flowering needs vernalization; 8 knots top; it is a lie if there is no sun without flowering. Flowering requires high temperature, and it will blossom for 100 days in May.
