Instructions Chevron Down Chevron Forward
    Growing Instructions:

    Bachelor Button seeds can be sown directly into the garden when the soil is warm and all danger of frost is passed. Soil temperature (not air temperature) should be warmer than 16°C (60°F) for seeds to germinate Planting at a lower temperature will delay germination. Choose a location that receives at least 6 hours of sunlight daily. Space seeds and plant to the depth indicated below. Press seeds into the soil to ensure good contact and cover with 6 mm (1/4") of soil. After planting, water the seeds with a gentle mist or shower. A hard spray can wash soil away, dislodge seeds and clump them together. It is critical to keep the soil consistently moist, but not soggy during germination. Do not let the soil dry out, as young plants have underdeveloped roots and can quickly dehydrate, particularly in windy conditions. When your seedlings reach a height of a few centimetres (inches) and have developed 2 or 3 pairs of leaves, it is important to thin them out, according to the plant spacing indicated below to provide good air circulation and room to grow.

    For earlier blooms, seeds can be started indoors 4-6 weeks before the last frost in your area. Follow the seed depth and spacing guidelines indicated below. Once all danger of frost has passed, seedlings should be hardened off before planting in their growing location. Seedlings should be transplanted according to the plant spacing directions below. Regularly monitor your plants and ensure that the soil remains moist while they establish themselves in their new environment.

  • Instructions for Nutrient Care: Feed plants SUPERthrive once per week. Mix 1.2 ml (1/4 tsp) per 4L (1 gallon) of water in a watering can and apply solution to the base of the plants.
  • Plant Spread: 20 cm (8")
Suggestions Chevron Down Chevron Forward
Growing Suggestions:
  • Regularly removing spent flowers, known as deadheading will promote continuous blooming and encourage the growth of fresh buds.
  • Harvest flowers for indoor arrangements when they are about 1/4 open. The color should be visible at the top, but no petals should have unfurled yet. Do not worry if you cut them at this stage, they will continue to open. When cutting, make sure to cut deeply. For the first harvest from the plant, cut down to where there are only 3-4 sets of leaves remaining. This will cause the plant to grow longer stems and more of them. Afterward, cut back to the main stem. Click here to learn more about harvesting flowers.
  • Blooms can last as long as 2 weeks in floral arrangements.
