Hyacinths are very reliable spring bloomers with spiky flowers and a sweet fragrance that they give off every year. Although buying bulbs is often considered faster, propagation by seed or staggered bulbs are surprisingly simple.
Most hyacinth varieties are grown from bulbs developed in the Netherlands. It is very difficult to grow them from seed.
So in this article, you’ll discover how to plant hyacinth seeds. Let’s start.
Step 1: Find a suitable location
To germinate seeds outdoors starting in the spring, shade from wind and mice is required. The soil should be somewhat sandy for good drainage. Cover the planting soil to prevent weeds from growing and damaging the seedlings.
Step 2: Measure and prepare the nursery
Dig 3 feet long and 18 inches wide to the depth of the pot. Place a garden towel in this area and fold the long side 5 inches toward the end of the tray. Six 18-inch long trays will fit in this area. Press the cloth into the bottom of the pot and staple the ends together.
Step 3: Prepare a pot
- Fill the pot with water.
- 1-inch potting soil in the bottom of the pot.
- Add 1 inch of mulch material
- Add another inch of soil
- Sow the seeds at a depth of 1 inch (12 mm) at 6-inch (15 cm) intervals.
Step 4: Place planting tray in the planting bed
Spread out the trays and fold the fabric around the edges of the two outer trays. Fill in the soil around the three trays. Water all three trays with enough water.
Step 5: Cover the tray with a glass plate
Place a 1/4-inch thick glass plate over the pot to protect it from burrowing animals, mice, and other pests.
Step 6: Care and maintenance
Keep the nursery moist by watering twice a week. Cut glass cloth and landscape to steam in. Seeds will begin to germinate in 1 to 3 months. When the first frost comes, remove the glass and spread the cedar mulch.
Place an additional landscape cloth over it and tuck it in loosely to protect it from frost. Leave the germinated seedlings for a year.
Step 7: Preparations for transplanting
In the second year, the surviving seedlings can be transplanted. Find a shady spot in the garden. Dig an 8-inch hole underneath, add 1/2 cup of organic mulch material, and sprinkle loosely with soil. Plant the seedlings with strong roots about 5 inches deep in the soil.
Step 8: Flowering
Hyacinths grew from seed take 3 to 6 years to flower. Protect the planted hyacinth with landscaping fabric around the stem and organic mulch.
Propagation of hyacinths by seed
To sow hyacinth seeds, remove the seeds from healthy hyacinth flowers when they have finished flowering. Place the compost mixture intended for sowing seeds in a pot. Spread the seeds evenly over the surface of the growing soil and cover them with a thin layer of clean horticultural gravel or clean coarse sand.
Water the trays and place them in a cool place, such as a greenhouse or cold frame, and let them mature undisturbed for a year. When the hyacinth seeds have matured for a year, the seedlings can be planted in pots or transplanted directly into the garden and cared for as usual.
Compensated propagation of hyacinths
If you want to know how to propagate hyacinth bulbs instead of seeds, no problem. The method is actually very simple. When the leaves die, small displaced bulbs grow at the base of the main bulb. The displaced bulbs can hide deep in the soil, so dig deep around the perimeter of the plant.
When you find the bulb, carefully separate it from the parent plant. For a more natural look, simply drop the bulb into the soil and plant it where it falls. Any branches that remain on the bulb will die back on their own.
Can hyacinth seeds be propagated?
Propagating hyacinths is not the quickest or easiest method, but with a little patience, hyacinths can be grown from seed. To do this, the hyacinth seeds must first mature on the plant. Don’t cut off all the hyacinths after they bloom, but leave some to form seeds.
At first, they are light green and fleshy, but as they mature they turn brown and break open, scattering small black seeds. The easiest way to store hyacinth seeds is to wrap a hyacinth flower with seeds in a nylon sleeve and collect the seeds when the pods have disintegrated.
It is important to note that hyacinths grown from seed will not necessarily be of the same variety as the seeds collected. When plants are sexually propagated (seeded), the plants produced often take on the characteristics of other parent plants.
Therefore, the best method for propagating plants that are exactly the desired variety is asexual propagation, such as by dividing plants or by cuttings. For hyacinths, the best way to produce more of a particular variety is to plant small bulbs that can become mother bulbs.
how to plant hyacinth seeds
Once the hyacinth pods are cracked, carefully pull off the nylons, collect the seeds, spread them out, and let them dry. Once dry, store the seeds in an envelope or paper bag in a cool, dry place for later use.
Fresh seeds are most effective. Then soak the seeds in warm water for 24-48 hours. There are two ways to germinate hyacinth seeds.
One is to sprinkle a thin layer of hyacinth seeds on a damp paper towel, cover it with another damp paper towel, and carefully place it in a plastic bag. Place the plastic bag in a place in the refrigerator where it won’t be disturbed or crushed, and just wait for the seeds to germinate in the refrigerator.
Then plant a 5-7.6 cm section in a seed tray filled with a mixture of peat moss and perlite and place this tray in the refrigerator or greenhouse. Another method is to plant the seeds directly into a tray filled with a mixture of peat moss and perlite and place the tray in a cold frame or greenhouse.
Both methods require patience. In the first year, only a few hyacinth leaves are formed. In this first year, seed energy is used for the growth of bulbs, not leaves or flowers. When hyacinths are grown from seed, some varieties may take up to six years to bloom.
For hyacinths grown from seed, bulb growth is the primary focus for the first two to three years, but monthly applications of rooting and bulb fertilizer can encourage bulb growth. Patience is important for the proper propagation of hyacinth seeds.
