CUSTOM MID-HEIGHT ANNUAL MIX
Your Key to Success
Maintenance is essential ingredient in the creation of a successful wildflower planting.
The key to an effective, long-term wildflower maintenance program is evaluation and timely
follow-up. The site should be evaluated periodically during the growing season to
determine if expectations are being met. Some conditions must be dealt with promptly
while others may be corrected at a later time. Here are five areas of maintenance
that require consideration: (1) reseeding, (2) weed control, (3) supplemental
watering, (4) fertilization, (5) fall mowing and cleanup.
(1) Reseeding
Many people prefer the vibrant, long-lasting colors that are provided by annuals. In most
parts of North America, there is just one way to create annual color year after year - by
reseeding. Exceptions are the Pacific Coast and the states bordering the Gulf of
Mexico, where annuals readily reseed on their own. Annuals can be reseeded in the
spring or fall. Spring reseeding should be completed as soon as the ground is
workable to take advantage of spring moisture. Remember that the planted area must
be kept consistently moist for four to six weeks to ensure good germination. In cold
climates, fall seeding should be quite late so germination does not occur until the
following spring. In mild climates, planting annuals in the fall will ensure an
early display in the spring. Important: follow our recommendations for appropriate
planting rates because reseeding too heavily may cause crowding and poor growth. If
emphasizing perennials is your goal, inspect the planted area and roughly note the number
and kinds of perennials growing there. Bare areas, if any, can be overseeded with
the original planting mix or with a custom mix. Establishing a solid cover of
perennials is one of the best ways to control weeds. When reseeding, some scarification of
the soil surface may be necessary to ensure good seed-soil contact. A mixture of
spring, summer, and fall-blooming perennial wildflower will produce a changing display of
color throughout the growing season.
(2) Weed Control
A monthly program of weed control is essential to ensure a satisfactory display of
wildflowers year after year. Weeds should be eliminated as soon as they can be
recognized, either by pulling, spot-spraying with a general herbicide, or selective
cutting with a string trimmer.
(3) Supplemental Water
Water is a critical factor in wildflower maintenance. During the hot summer season,
up to one-half inch of moisture per week may be required to keep wildflowers at their
peak.
(4) Fertilization
Fertilization may be beneficial in a long-term maintenance program, particularly if the
soil is sandy or very poor in nutrients. If there is a reason to suspect a problem
with soil fertility, we recommend a soil test and/or plant tissue analysis. These
tests will enable you to determine which specific fertilizer may be appropriate for your
needs.
(5) Fall Mowing And Cleanup
If a neat appearance is desired after the wildflowers have gone to seed, mow them to a
height of four to six inches. To prepare the area for fall seeding, it may be
necessary to remove any excessive plant material or mulch that could prevent good
seed-soil contact. We cannot stress too strongly the importance of a regular
wildflower maintenance program, which will be dictated by the specific goals of the
project. You will be rewarded with a wildflower planting that meets or exceeds
expectations and provides a beautiful display year after year.
