Start by getting all the necessary supplies. You will need some fresh hydrangea seeds, seed trays, a good seed-starting mix, and a spray bottle.

Make sure you have a sunny spot or a grow light to provide the needed light for the seedlings. With your tools and seeds ready, you are all set to jump into the next step!

Prepare the Seed Trays

Start by filling your seed trays with seed-starting mix. Lightly press the soil down, but don’t pack it too tightly.

It creates a nice bed for your seeds to grow in without making it hard for roots to spread. Make sure there’s good drainage to prevent your seedlings from getting waterlogged.

Plant The Seeds

Now comes the fun part! Sprinkle the hydrangea seeds on top of the soil.

Try to spread them out evenly. Lightly press them into the soil without covering them completely.

Hydrangea seeds need light to germinate, so keep them close to the surface!

Water Gently

Using a spray bottle, gently mist the soil to keep it moist. Be careful not to drown the tiny seeds; just keep the surface damp.

Check on them daily and mist as needed. Proper moisture is key to ensuring your seeds get off to a great start.

Provide Light and Warmth

Place the seed trays in a sunny spot or under a grow light. Hydrangea seeds need about 10-12 hours of light a day to germinate.

Keep them warm—aim for a temperature between 65-75°F. Warmth and light will kickstart the germination process!

Transplant the Seedlings

Once your seedlings have grown a few sets of true leaves, it’s time to transplant them. Carefully move them to larger pots with a rich, well-draining soil mix.

Handle the seedlings by the leaves, not the stem, to avoid damage. Give them some space to grow bigger and stronger.

When your plants are sturdy and the risk of frost has passed, it’s time for the big move! Gradually acclimate your hydrangeas to the outside by putting them out for a few hours each day.

Then, find a cozy spot in your garden with partial sun and well-drained soil to plant them permanently.

Regular Care

Once your hydrangeas are settled in their new home, keep an eye on them. Water them regularly, especially during dry spells.

Feed them with a balanced fertilizer according to the package instructions. With a bit of love and regular care, your hydrangeas will flourish into stunning shrubs!
