Don't forget fall plant orders will be delivered
during the fall teachers meetings at the end of the month!
Do you have what you need for this growing season?
This is just
a basic help guide for the average school grower, I realize some of you are
much more extensive with your greenhouse and if you have other
specific questions please let me know.
Bedding plants/ annuals ordered from South Region come 288 flats to a plug tray. If you plant these in Jumbo 606s you will get about 8 flats per plug tray. These are usually sold 100 per case. You will also need the web flats (the trays that hold the insert).
Poinsettias: you will need one 6 in pot per Poinsettia and don't forget support rings if you didn't order those with your cuttings.
Ferns: If ordering from the south region you will have 84 ferns per tray. Great way to save money and not put 3 plugs to 1 hanging basket is to transplant plugs into 4" pots until Nov or when roots fill pot, then transplant into 10" hanging baskets to grow out for spring plant sale
Fertilizer: Osmocote Plus 15-9-12, top dress each pot w. one teaspoon every 10-12 weeks (I know some of you have your own recipe but this is a general guideline)
Perennials: are usually grown and sold in either gallon nursery pots or larger azalea pots
Growing Media: Fafard 3-B is a good mix and usually one 3cuft bag will fill fifteen 606 trays or 120 4in pots or fifteen 10in baskets or 45 6in pots or 30 gallon pots -
Fungicides: Banrot is a good general fungicide to cover most greenhouse fungus problems
Insecticides: Marathon for whiteflies, aphids, or other sucking insects, Conserve for thrip, leafminer, or worms, there are lots of others out there that work great but these are good basics. Safari works the absolute best for white flies but has a pretty high price tag if you can afford it, that would be a good #1 go to.
Herbicide: Finalle is good to control weeds in the greenhouse and Roundup for weeds outside the greenhouse.
13-2-13 Plug Special Peters Water Soluble (25 lb bag) is recommended at 100 ppm for a successful cool season crop this year
20-10-20 with 100-150 ppm Nitrogen to encourage initial leaf expansion and branching
Always use a nitrate fertilizer with low rates of phosphorus to maintain compact plant growth
Shade cloths Fall bedding plants and poinsettias benefit from
full sunlight during the months of September, October and November.
Plugs and rooted poinsettias do best with some shade when first planted, but after they are established, they will do better with full sun.
Pull off and store your shade cloths by the middle of October.
Ideally fall bedding plants can be left in the greenhouse for approximately 2 weeks after transplanting and then moved outside to finish off.
The additional light and cooler temperature of the outdoors will produce a more compact bedding plant crop.
The use of a growth retardant ( i.e. Sumagic/A-rest )will help control stretching.
B-nine is reported to be ineffectual on snapdragons and any retardant used on
snaps will need to be used at a higher rate than pansies.
LIVE PLANT License: Has everyone reapplied for your school license this year??? These expire every year and every school that grows live plants MUST have one! Here is the link to more info on a live plant license - http://agr.georgia.gov/licensing-and-inspection.aspx
As soon as you get your new license, laminate it and hang it in the greenhouse.
