Growing roses from rose calyx, also known as rose hips, can be a rewarding process. Rose hips are the seed pods that develop after the flowers have faded. Here’s a step-by-step guide on how to grow roses from rose calyx:
Rose Hips (Calyx): Collect mature rose hips from healthy and disease-free rose plants. Choose hips that are plump and have turned a vibrant color.
Sharp Scissors or Pruners: To open and extract the seeds from the rose hips.
Seed Starting Mix: A well-draining and sterile mix for germinating seeds.
Seed Trays or Small Pots: Containers for planting the seeds.
Plastic Wrap or Clear Plastic Dome: To cover the seed trays or pots and create a greenhouse-like environment.
Watering Can or Spray Bottle: For watering the seeds.
Labeling Materials: Markers or labels to identify the rose varieties.
Collecting Rose Hips:
Harvest rose hips when they are fully ripe, usually in the fall after the petals have fallen off.
Use sharp scissors or pruners to cut the hips from the plant, leaving a small stem attached.
Cut open the rose hips and remove the seeds. Be careful, as some rose hips may have irritating hairs.
Clean the seeds by removing any remaining pulp.
Many rose seeds require a period of cold stratification to break dormancy. Place the seeds in a plastic bag with a moistened paper towel, seal the bag, and refrigerate for 4-6 weeks.
Preparing Seed Trays or Pots:
Fill seed trays or small pots with a seed starting mix. Moisten the mix slightly.
Place the seeds on the surface of the soil and press them in lightly. Do not bury them deeply.
Covering and Watering:
Cover the trays or pots with plastic wrap or a clear plastic dome to create a humid environment.
Water the seeds lightly, ensuring the soil stays consistently moist but not waterlogged.
Place the trays or pots in a warm location, such as a sunny windowsill.
Germination may take several weeks to months, depending on the rose variety.
Once the seedlings have developed true leaves and are large enough to handle, transplant them into larger pots or directly into the garden.
Gradually acclimate the seedlings to outdoor conditions by exposing them to sunlight and outdoor temperatures over a period of 1-2 weeks.
Planting in the Garden:
Choose a sunny location with well-draining soil for planting the rose seedlings in the garden.
Care and Maintenance:
Water the young plants regularly, and provide adequate spacing for air circulation.
Mulch around the base of the plants to retain moisture and suppress weeds.
Fertilize according to the specific needs of the rose variety.
Growing roses from rose calyx can be a patient process, but with proper care, you can enjoy the beauty of your own cultivated roses. Keep in mind that not all roses come true from seed, and there can be variations in flower color and form.
