How to grow sunflowers? It’s actually very simple to grow sunflowers. You don’t need too much pots, too much soil, or even too much care. You can try it too!
The first step: selection
Selection is very important. There are different varieties of sunflowers. There are edible ones, the one that produces melon seeds. It is said that they can grow up to 3 meters in height. Of course, the flower pots are also very large, and the flowers are huge. It is generally better to use small flower pots at home, so you should choose the seeds of ornamental sunflowers that have been dwarfed.
Step 2: Seeding
(1) Time-It is recommended that after the beginning of April, the temperature can be stabilized at around 20 degrees before sowing. At this time, the seeding does not need to be soaked in advance. Throw it into the soil and it will germinate in 3 days and transplant in 5 days. fast.
(2) Seedling soil-Seeds cannot germinate for a long time when the temperature is low. At this time, if the soil used for growing seedlings is the old soil that has been planted with other plants last year, it is likely that there are small insect eggs in the soil, and the seeds have not yet germinated. , The eggs hatch first, and then the flesh of sunflower seeds becomes the best food for the larvae!
(3) Nursery pots-you can buy a special pot for nursery, which is the kind with a transparent cover on it, so as to prevent the evaporation of water, and secondly, you can see the germination of the seeds. Of course, it can also be planted directly in a large pot, but remember to put a layer of plastic wrap on the surface after pouring it thoroughly, so as to prevent the water from evaporating too quickly while keeping the temperature warm. There is no need to add water during the emergence period.
To sum up: if you use ordinary soil, sow hot spots to avoid being eaten by bugs; if you use advanced seedling soil, sow early is fine, but you still have to wait a long time before sprouting. So, don’t be anxious, and plant the seeds later!
Step 3: Transplant
When the sprouted seedlings are unearthed, and the two lovely cotyledons are opened (I don’t know if they are called cotyledons? Anyway, they are the two that grew at the beginning), then they can be transplanted into a big pot! The pots don’t need to be too big, one seedling per pot, don’t be greedy to plant too much, so that the nutrition is not enough, the place is too small, and finally the leaves will not open.
After transplanting, pour enough root water, and be sure to pour thoroughly. Then just put it there. It is recommended to put it in a sunny place indoors. If there is a sun room, put it in the sun room. Don’t put it in the open air immediately, because the temperature in early spring is not stable enough, and the temperature difference between morning and evening is still relatively large. Put it in the sun room for more sunshine, even if the temperature suddenly rises to 30 degrees in those few days, don’t worry that the seedlings will be killed by the heat. Sunflowers are naturally not afraid of heat.
Because it is a small seedling, it does not need much water, so you will find that after transplanting, as long as it is not placed in the open air, the potted soil will be wet for a long time. Don’t water it. You can leave it without watering for at least 1 week. Quietly and slowly begin to grow true leaves, two long true leaves, the speed will be very fast.
Step 4: Daily maintenance
When 3 or 4 pairs of true leaves are grown and they look stronger, they can be placed in the open air! If the weather is hot, water some water every night after the sun goes down. If possible, spray potassium dihydrogen phosphate once every 3 or 4 days to promote the growth of branches, leaves and flower buds. Then, wait slowly, waiting for the little surprise that belongs to you to come quietly in a sunny morning.
