FLOWER-AGERATUM - MARKET GROWERS BLUE

How to grow Ageratum-Market Growers Blue

1. Choose a site with full sun to partial shade.
2. Sow seeds directly into the garden during mid to late spring.  In tropical regions, sow anytime. Surface sow seeds and lightly cover them, as they need light to germinate.
3. Use a well-drained seed sowing mix at about 22°C.
4. Plant in rich, well-drained soils.
5. Ensure proper spacing to allow for good air circulation and prevent common pests and diseases. Plants will grow up to 70 cm tall by 50 cm wide.
6. Provide regular watering to keep the soil moist but not waterlogged.
7. Seeds will germinate best at a temperature of about 22°C.
8. Regularly deadhead spent blooms to encourage continuous flowering and keep plants tidy.
9. Monitor for pests and diseases and take preventive measures as needed.
10. Ageratum typically grows to be about 30-40cm tall. Provide support to the plants as they grow.
11. Pinch off dead flowers to encourage new blooms

Additional tips

1. Start seeds indoors:
   •  Ageratum can be started from seed indoors, 8-10 weeks before the last frost date in your area. Sow the seeds in seed trays or pots filled with seed compost and cover with a plastic wrap or propagator lid to maintain humidity.
2. Transplant seedlings:
   • Once the seedlings have grown to about 5-7cm tall and have at least two sets of true leaves, they can be transplanted into larger pots or into the garden.
3. Stratifying:
   • Although not necessary, cold stratifying the seeds for a week before planting can sometimes improve germination rates. Place the seeds in a damp paper towel, put them in a plastic bag, and store them in the refrigerator.
4. Companion Planting:
   • Plant Ageratum near vegetables and other flowers to deter harmful insects. Its strong scent can help repel pests such as whiteflies and aphids
5. Pinching Back:
   • Is especially effective for preventing the plants from becoming too leggy
6. Fertilising:
   • Ageratum prefers moderately fertile soil. Over Fertilising, especially with high-nitrogen fertilisers, can result in lush foliage at the expense of flowers
7. Humidity Tolerance:
   •  Ageratum can tolerate high humidity levels, making it an excellent choice for humid climates where other plants might struggle.
8. Edging and Ground Cover:
   • Use Ageratum as a living mulch to suppress weeds. Their dense growth can help keep weed growth down around taller plants.
9. Cut Flowers Longevity:
   • When using Ageratum as cut flowers, sear the cut ends of the stems with a flame or boiling water for a few seconds. This helps seal the stems and prolongs their vase life.
10. Pest Control:
    • Although Ageratum is relatively pest-resistant, keep an eye out for spider mites and thrips. A strong spray of water can help dislodge these pests, or use an organic insecticidal soap if needed.
