Do you have what you need for this growing season?
Make sure you order early, remember others are ordering too
and you don't want to be left out!! 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.
I have also attached a greenhouse crop schedule for the entire year to help you prepare your order for the entire school year.
Bedding plants/ annuals ordered from Central Region come 345
flats to a plug tray. If you plant these in Jumbo 606s you will get
about 9 - 91/2 flats per plug tray. These are usually sold 100 per
case. You will also need the web flats (the trays that hold the
Poinsettias: you will need one 6in pot per Poinsettia and don't forget support rings if you didn't order those with your cuttings.
Ferns: If ordering from the central region you will have 84 ferns per tray.
4" pots, 10" hanging baskets
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
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
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.
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 using NO3 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
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
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.
Remember, 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 his or her 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
