Eustoma, or lisianthus, develops long and slowly. Seedlings are planted at the age of 3 months, when the threat of return frosts has passed. Depending on the growing region and the conditions of planting in the ground, seeds are sown from December to February. Read the article on how to calculate the correct dates for sowing seedlings and open ground, and how to choose the best periods for sowing.

When to sow eustoma: calculating the optimal time
In order for eustoma to bloom before frost, seedlings are first grown. It is important to choose the optimal time for sowing.
The flower grows very slowly, so they stick to early dates, starting from the first months of winter. By the time of planting in the flowerbed, the seedlings are three months old, sometimes a little more.
Lisianthus seedlings should be planted on the site when the threat of return frosts is minimal. The soil should be warmed up to +10 ℃. The air temperature, even at night, should not fall below +12 ℃.

Reference
If you violate the planting deadlines, you may not be able to wait for the eustoma to bloom this season, or the flowers will bloom just before frost.
Timing of sowing seeds
Usually, sowing flower seeds begins in December and lasts until the first days of February, no later.
In November and the first half of December, it is still too early to plant eustoma, but from mid-February onwards, as a rule, it is too late.

When to plant eustoma seedlings in different regions
The timing of sowing lisianthus largely depends on the growing region. For example, in the Moscow region it is necessary to sow no later than the middle of the second month of winter; in the Leningrad region it is advisable to sow no later than the first ten days of January; in Siberia, the Urals and the Far East – it is better to plant eustoma at the end of the year.

Tips for growing eustoma seedlings
Seed material is usually sold in the form of dragees coated with a disinfectant solution. Therefore, the seeds do not require additional preparation. At the same time, flower growers noticed that if the shell is slightly disturbed before sowing – scarified – seedlings will appear faster.
Light
It is imperative to illuminate flower seedlings. On a cloudy day, the lamp should be on from 6 a.m. to 6 p.m. If the day is sunny, then the lamp can be turned on from 6 to 9 am and from 15 to 18 pm.

Choosing plants for a blooming garden
When to plant eustoma seeds in open ground
To grow eustoma without seedlings, seeds are sown in warm soil and a greenhouse is set up.
Sowing time in the ground
The most suitable month for planting lisianthus seeds in the ground is April. Previously, seeds are not sown because the soil is not yet warmed up enough. Later also makes no sense, because you simply won’t wait for it to bloom, the cold will come earlier.

5 ways to stratify perennial flower seeds at home.
Tips for growing eustoma in open ground without seedlings
Growing eustoma from seeds in open ground is carried out in a small greenhouse.
Important
Shoots in open ground may appear in 15–20 days – this is normal. If seedlings do not appear 25 days after planting, it means the seeds are dead.

Choosing a landing site
Open and well lit.
- If the bed is located on a slope, then it must be oriented to the south.
- It is better if the selected area is protected on the north side by a house wall or fence.
Reference
This amazing plant looks like a rose, and when cut it lasts many times longer than the capricious “queen of the garden.”

Setting the stage
First you need to warm up the soil in the garden bed well:
- Remove the top layer from the bed.
- Preheat to +21…+23 ℃.
- Place it on the bed again.
The thickness of the heated soil layer should be 2 cm.
Before planting, the soil is loosened, leveled, plant debris is removed, and weeds are removed.
Covering the plantings
Seeds can be sown directly on the surface. Leave a distance of 10 cm between the seeds. After sowing the seeds, the bed needs to be covered with film, building some kind of greenhouse.
- In an improvised greenhouse during the day, the temperature should not fall below +21 ℃, at night it should not fall below +15 ℃.
- The greenhouse cannot be removed until the seedlings form a pair of true leaves.
- Then the greenhouse can be opened slightly during the day, gradually accustoming the seedlings to the open air.
- Around the beginning of July, the greenhouse is removed and the plants are transplanted to a permanent place.
Council
Do not allow the soil to dry out or become waterlogged.
How and when to plant eustoma: growing experience
Many people like eustomas – graceful roses with delicate colors. However, many refuse to grow them, since they have to wait 9 months for flowering, and the plant does not overwinter in the middle zone – even with shelter.
How and when to plant eustoma
Growing eustoma from seeds is real magic that anyone can do. The process, of course, is long, but not difficult. But what a result! So, we sow eustoma.
When to sow seeds?
We start in December-January, at the latest in February. To see flowering earlier, sow even from October.
What kind of soil does eustoma like?
Eustoma needs special soil: nutritious, loose, light and always neutral acidity. For better growth and development, you need to take peat tablets or special soil briquettes, but there is also a budget option – very loose peat soil.
Important
Chernozem is absolutely not suitable for planting eustoma! The structure of the soil should be light and homogeneous, well permeable to air and water. In such favorable conditions, the fragile roots of eustoma will develop optimally; a complex of nutrients will ensure the growth, health and abundant flowering of these wonderful flowers.
How to sow eustoma correctly?
- Before sowing, it is necessary to moisten the surface of the substrate well: 2–3 cm in the greenhouse will be enough.
- Eustoma is sown superficially, without deepening.
- It is imperative to add 1-2 drops of water with any growth stimulator, vitalizer (for example, HB-101) to each seed.
- Next, the container is covered with film or a special transparent lid.
- Periodically check that the substrate remains slightly moist, but not flooded – eustoma does not like swamps!
Reference
Eustoma seeds are very small and are sold coated (coated). Convenient when planting: moisten a toothpick and carefully move the seed into the substrate.
What to do when eustoma has risen?
Eustoma seeds can germinate for quite a long time – it all depends on their freshness. The plants will be barely noticeable on the surface of the earth – they are so tiny and delicate.
From this moment until picking, they need to be ventilated and watered very carefully; additional lighting will not hurt either.
When to pick eustoma?
- They grow very slowly for the first 3 months, but then they actively begin to grow green mass.
- As soon as 2–4 adult leaves have formed, the plants can be picked into separate cups.
When to pinch eustoma seedlings?
After the eustoma reaches a size of 5–6 cm, the crown of 2 leaves must be pinched. Then new shoots will begin to form in the axils of the leaves, and the thin twig will turn into a rich, chic bush with many buds.
The main thing is not to wait for the baby to stretch out: feel free to shape his grassy crown, and he will thank you with lush flowering.
When will eustoma bloom?
- Eustoma blooms only at 18–20 weeks from germination.
- With the recommended sowing dates, flowering occurs in June – July.
When to transplant eustoma?
The root system of eustoma is fibrous and takes up very little space in the pot. If possible, the plants are transplanted into a greenhouse in the summer, as soon as the threat of frost has passed.
They get along well with tomatoes, and the wind won’t bother them too much, since eustomas really don’t like open, windy areas.
Reference
They do not require abundant watering, like cucumbers, but they cannot tolerate drought either: everything should be in moderation.
How to preserve eustoma
The most delicate eustoma has incredibly magical beauty. Many varieties, colors, shapes of buds and petals make it a favorite among gardeners. How many years can you keep bushes of your favorite flowers? The secrets of plants will be revealed by an observant person who plants with love.
When to collect seeds?
Faded buds can be left directly on the plant and the seeds can be allowed to ripen. And next year you will already have your own seed, the germination rate of which will be almost 100%.
Experimenting and seeing what color and shape the flower will turn out for next season is very interesting, especially for children.
When to replant eustoma for the winter?
- Before frost, the bushes, which are planned to be left until next year, are dug up and transplanted into small pots.
- Adult bushes must be cut at a distance of 8–10 cm from the surface of the ground and brought into a warm room.
- Eustoma can safely continue to grow indoors and even bloom.
- In wintering lisianthus, sometimes the main stem begins to dry out. Don’t rush to throw away the plant. Closer to the ground, it could have preserved buds from which new shoots would develop.
In the warm spring, the overwintered lisianthus will again be ready to move into the garden to delight you and your family with magical blooms.
Reference
There are low-growing varieties on sale that feel great in an apartment and do not need to move to the garden for the summer.
