APRIL TO DO LIST (edited from DRS 3-21-05)
1. Potting on mums into 4” or 6” pots
· Soilless growers who are using the club recommended M&R mix. This mix is ph balanced at 6.5 and contains a good mix of fertilizers that carry the plant for 3-4 weeks. It requires no additives at this time, but some growers like to add a little Alfalfa meal and some additional pumice for increased aeration.
· Soil or compost mixes: See McGlashen mix in the McGlashen Hand Book. You’ll need to mix your own soil, consisting of compost, or garden loam plus slacked Lime or Dolomite to keep soil sweet plus Steamed Bone to promote root growth. Also, ashes and a little Rose and garden fertilizer (i.e. 4-10-8 or 5-10-10) Pumice or grit may be added to loosen the soil mix.
· Wash previously used pots in a mild Clorox bath (bleach), then rinse in clear water.
· Clay pots are recommended for 4 or 6 inch potting as they breathe and dry out faster during cool April days.
· Pot on when a significant ring of roots forms around the bottom edge of the pot (semi root bound). Do not compact the potting mix. Tie plants to small stakes.
2. Move mum pots outdoors as weather warms. Choose a sunny location.
· Bury pots to rim if using clay. Protect from frost, wind, dogs, cats and Children.
3. Review stopping dates. Most ECA cultivars are stopped Between April 15 and May 30.
· Pinch date lists for most club cultivars should be available at the April meeting. Contact your Coach for other cultivars not on the list.
4 OTHER CARE:
· Control Aphids. Spray for Aphids every 2 or 3 weeks, with liquid Diazinon, or other insecticides. Water only as needed, do not over water.
· Continue culling process in April to get to your final growing group. The 6” potting should be used for this reduction. Don’t always keep the first plants to reach 6” potting stage. Keep the best cultivars. Share surplus plants with other club members. Throw away damaged or diseased plants.
Fertilize weekly starting the 3rd or 4th week after potting. Standard Miracle Grow is recommended. Water soluble 10-50-10 Peter’s upper blossom booster is also a good substitute.
(Please note the change in recommendation for starter fertilizer. In 2009, Don Stark indicated that water-soluble 10-50-10, Peters Super Blossom Booster plant food, is available at local garden stores or McLendons Hardware in 1.5-pound bags. The application directions indicate 1 tsp per gallon of water for indoor use. Use this fertilizer as a supplement through the 6” pot stage. Don noted that Peters 20-10-20 will be available for use through the summer growth season.)
