Flower Bed Preparation
Special note for Impatiens growers:
The high ammonium nitrate content of Greencare and Multicoat timed release fertilizers, can cause rapid stem
elongation (stretching) of Impatiens, particularly in a heavily shaded area. To avoid this problem, do not use Greencare
or Multicoat timed release fertilizer, in your Impatiens beds. An inexpensive 10-10-10 garden fertilizer applied
at 3-4 lbs per 100 sq feet usually suffices. Use supplementary liquid feeding, or additional broadcast feedings of
10-10-10 if plants show signs of yellowing.
Hanging Basket Maintenance
Most of our hanging baskets contain an application of Greencare timed release fertilizer added at planting . Supplementary
feedings of liquid fertilizer on a bi-weekly basis will be beneficial.
Careful attention to watering is necessary for hanging baskets – especially in hot or windy weather. Gerten planted
baskets are planted in extra deep pots for additional soil holding capacity. Most include a special reservoir to aid in
water retention.
SPACING AND SOIL AMENDMENT GUIDE
To estimate the number of annuals needed to Spacing Multiply
fill a space first determine the square footage of Requirements sq. feet by
the space:
4" (on center) 9.00
Area of rectangle = 6" 4.00
Length x Width 8" 2.30
9" 1.80
Area of Triangle = 10" 1.40
1/2 base x Height 12" 1.00
15" 0.65
Area of circle = 18" 0.45
3.14 x (radius) (radius) 24" 0.25
30" 0.16
Once you know the square footage, use the
chart on the right to determine the number of
annuals needed.
