Hydrangeas are beautiful flowering shrubs that can be used to create a stunning display of color in your garden. They can also be grown indoors, as long as you provide them with the right environment and care.
How To Plant Hydrangea Seeds
Here is the complete process explained in detail on how to plant hydrangea seeds:
1. Start with fresh seeds.
If you’re starting your seeds indoors, use a hydrangea seedling that’s less than 6 months old.
If you’re planting outdoors, use fresh seeds from the current year’s blooms.
2. Soak the seeds overnight in water.
3. Fill a pot with moistened soil.
4. Plant the hydrangea seeds about ½ inch deep and cover with soil mix or sand to keep them from drying out while they germinate (sprout).
5. Keep the soil moist but not soggy until the seedlings emerge and grow several inches tall, which takes about 3-4 weeks under ideal conditions.
6. After the first true leaves appear, gradually expose the seedlings to more light by moving them to a sunnier location indoors or outside as weather permits, until they are ready to be planted in a permanent location after their second growing season (about 2 years).
7. If you want instant gratification, plant your hydrangea seedlings in pots and move them into an area where they will get full sun for at least 6 hours per day when they are ready to be transplanted (after their first growing season).
It is important that they get enough sunlight at this stage because it helps make up for what they missed when they were inside as seedlings! Once moved outside, keep them well watered so that the root systems stay healthy and don’t dry out too quickly once established in their new homes!
Tips for How To Plant Hydrangea Seeds
Here are 5 things to take care of with respect to how to plant hydrangea seeds:
1. The seeds should be planted in a potting soil that is rich in organic matter and well drained.
2. You should plant the seeds approximately ½ inch deep.
3. Planting them too deep will cause them to not sprout, and planting them too shallow will cause them to dry out before they can sprout.
4. Moisten the soil with water before you plant the seeds so that it is moist but not wet when you plant the seeds.
5. Keep your hydrangeas in a part of your house where they won’t get too hot or cold for too long, because they are susceptible to heat damage if not properly stored!
Interesting Facts About Hydrangea
Here are 5 things you should know about hydrangea:
Large hydrangea plants are not always better. In the case of hydrangeas, large shrubs are more likely to have weak stems and less blooms. Smaller shrubs tend to be sturdier, produce more flowers and be easier to care for. Hydrangeas don’t need as much sun as you might think. While they prefer full sun, most varieties will do well in partial shade or even deep shade.
They also grow very well in containers or hanging baskets where they can get the light they need without competing with other plants for space. Hydrangeas do best in moist soil but do not like wet feet. They grow best in soil that is moist but not saturated with water.
They should never be planted near a pond or creek or anyplace where the roots may become waterlogged. The leaves of hydrangeas turn a beautiful red color when they are stressed by too much heat, drought or cold temperatures.
If your hydrangea has leaves that are turning red but otherwise looks healthy and green, it is likely just stressed by extreme weather conditions and should recover nicely once the weather cools down again.
In fact, if you live in an area that gets hot summers you can actually help your hydrangea survive by watering it less during those hot months so that it doesn’t get over-stressed by the heat!
Many hydrangeas will bloom all summer long when grown in areas with mild summer climates such as California and southern Florida but will only bloom for a few weeks each year if grown where summers are very hot and dry like Arizona or Texas.
It is not difficult to grow hydrangeas from seed. In fact, it is very easy to do so. Seed germination of hydrangeas occurs within two weeks and the seedlings are ready for transplanting after six months. Hydrangea seeds are best planted in the fall or in spring as they need cold stratification before they can germinate.
The easiest way to achieve this is by placing the seeds in a plastic bag and storing them in your refrigerator for one month prior to planting. It is important that you store them in a bag, as it will trap moisture that will be needed for successful germination.
How far apart should I plant hydrangeas?
Hydrangea plants require ample space between each plant and between rows of plants when growing hydrangeas from seed. The distance between each plant should be at least 4 feet apart, while the distance between rows should be 6 feet apart. This will allow room for the mature plants to spread out, along with plenty of room for pruning. As with most plants, too much crowding will cause stress and stunt growth which may lead to poor flowering or even death of the plant.
Hydrangea seeds germinate best in cool soil, so you should plant them after the last frost. This means that if you live in a warmer climate, you’ll have to grow your hydrangeas from cuttings or take seeds from plants that have grown in cooler climates.
How do I plant hydrangea seeds?
Hydrangea seeds are tiny and hard to handle, but they aren’t difficult to plant. Just follow these steps:
1. Use a trowel or other small digging tool to dig a hole about 1½ inches deep and 2 inches wide. You can use containers such as egg cartons or old pots to make planting easier. If you’re planting several seeds at once, space them about an inch apart in the hole.
2. Fill the hole with water until it is about ¼ inch deep, then let it drain out of the bottom of the container into a bucket or other container for later use if needed.
3. Sprinkle the seed on top of the wet soil, then cover with ¼ inch more soil and pat down gently with your hands so that there are no air pockets around any of the seeds.
4. Water well and keep moist until seedlings appear, which may take up to three weeks depending on conditions, especially temperature and moisture levels in your garden bed or pot.
5. Once seedlings emerge, thin
It takes hydrangeas about a year to bloom from seed. It’s important to note that these plants require chilling hours before they will bloom, so you may need to wait until the following spring for your flowers.
How do I plant hydrangeas from seed?
Hydrangeas are easy to grow from seed, but you will need to start them indoors. You can also try planting them directly in the garden if you live in zones 7 or higher. If you live in zone 6 or colder, we recommend starting them indoors and then transplanting once the weather has warmed up. To start your seeds, follow these steps:
Fill a seed-starting tray with moistened potting soil and sprinkle the seeds evenly over the surface of the soil. Cover the seeds lightly with more potting soil and place in a warm room until they sprout. Once they have sprouted, place them under fluorescent lights until they reach about 2 inches tall. At this point, it is time to transplant them into individual pots or plant them outside if you live in zone 7 or higher. To transplant outdoors, dig holes deep enough to accommodate the roots and set each seedling into its own hole at a 45-degree angle away from the parent plant (to avoid root competition). Water well after planting and keep watered regularly throughout spring and summer as needed.
Can I grow hydrangeas from cuttings?
The time it takes for a hydrangea to grow depends on the cultivar and the size of the plant. Some hydrangeas can grow very large. Hydrangeas are generally classified as small, medium, or large shrubs. Small hydrangeas grow up to 3 feet tall and wide. Medium-sized hydrangeas grow up to 6 feet tall and wide. Large hydrangeas are usually over 6 feet tall and wide. It can take large hydrangeas from three to five years to reach full maturity, depending on how long they have been growing in the nursery before being transplanted into your garden.
When planted in the ground, it can take smaller plants just one year to reach full maturity after transplanting into your garden (depending on how long they have been growing in the nursery). When grown as container plants, it can take two years or more for them to reach full maturity.
How do I know when my hydrangea is mature?
Hydrangea flowers come in many different colors: blue, pink, white, red and purple. The color of your flower will depend on what type of soil you have in your garden as well as which type of fertilizer you use during the growing season. Hydrangea flowers are formed by leaf buds at the end of branches that emerge from the base of each stem.
