easy grow guide marigold whitegold max (F1 Tagetes erecta)
Plug Production: 288 plugs or larger
Sowing/Media:
Use a well-drained, disease-free, peat based plug medium with pH 6.2-6.5 (avoid pH levels <6.0), EC <0.75mmhos. Cover seed with vermiculite Keep medium uniformly moist until seedlings are hooking above the covering, media temperature should be 68-72°F (20-22°C), light is not essential but light levels <1500 f.c. are beneficial. Dry down slightly to avoid stretch, keep media temperature at 68-72°F (20-22°C), germination should be complete in 5-7 days. Allow media to dry further between irrigations to improve rooting and control stretch, media temperature can be dropped to 65-68°F (18-20°C), light levels should be <3000 f.c. Fertilize with 100-150ppm N from 15-5-15, 17-5-17 or 13-2-13, keep media pH at 6.2- 6.5 (low pH can cause iron deficiency) and EC <1.5mmhos. Practice good wet/dry moisture cycle, maintain media temperatures at 65-68°F (18- 20°C), light levels <5000 f.c. Fertilize with 100-150ppm N from 13-2-13 to help tone the seedlings. PGR’s shouldn’t be required but If needed, use sprays of B-Nine (1500 – 2500 ppm), A-Rest (3 – 10 ppm), Bonzi (10 – 20 ppm), or Sumagic (2 – 7 ppm) to control growth. It is best to run your own trials to avoid overdosing, as weather and cultural regimes can affect the requirements.
Germination Stage 1: (3-5 days)
Germination Stage 2:
Germination Stage 3:
Germination Stage 4:
Growing on to Finish: 4-6 inch (10-16cm) pots
Media:
Use a well-drained, disease free, peat-based growing mix with pH 6.2-6.5 (no lower) and EC <1.5mmhos. pH levels below 6.0 can induce iron, manganese and sodium toxicity.
Temperatures:
Day temperatures should be 65-68°F (18-20°C) Night temperatures can be lowered to 62-65°F (16-18°C)
Note: WhiteGold Max can be sensitive to cold temperatures and reddening can be seen on the foliage if average temperatures are below 59 ° F ( 15 ° C) for a number of consecutive days. This will revert back to normal once exposed to warmer conditions again. Light levels should be 3000 - 5000 f.c. as a guide. Marigold WhiteGold Max has a facultative short-day response.
Light:
Irrigation:
Practice a good wet/dry moisture cycle.
Feed 1 – 2 times per week with 150 – 200 ppm N from 15-0-15 or similar, occasionally using a 20-10-20 for more lush growth, but be careful not to lower the pH too much. Keep media pH 6.0 – 6.5, and media EC 1.25 – 1.75 mmhos (saturated paste). Use sprays of B-Nine (2500 – 5000 ppm), Bonzi (15 – 30 ppm), or Sumagic (5 – 10 ppm) if needed. A Bonzi drench (2 – 5 ppm) or Sumagic (1 – 2 ppm) can be used when plants are up to size and flowering if needed. It is best to run your own trials to avoid overdosing, as weather and cultural regimes can affect the requirements

Pests:
Aphids, Whitefly, Thrips, Red Spider mite, Leafminer
Pythium, Botrytis, Alternaria leafspot. A preventative fungicide program is recommended. Leafspots (bacterial and Alternaria), bronzing or speckling on lower leaves is likely to be caused by media pH <6.0.
