When to plant: Almost all perennial and many annual plants are best planted in the fall months of September, October, and November, seed is best planted in September and October. Plants can also be planted in the spring near the frost-free date.
Where to plant: Most of the wildflowers in our area require several hours of sunlight. They will usually do well in most soils as long as drainage is adequate. Those wildflowers that prefer shade will probably require alteration of the soil not discussed here.
Preparation of area: Although use of herbicides is usually not recommended, grassy areas are best treated with a glyphosate-containing herbicide. These must be applied to green vegetation, so will probably need to be applied well before seeding. Allow at least 2 weeks before seeding the area after application of the herbicide.
An alternate method would be to cover the dormant turf grass with several sheets of newspaper, cover that with a couple of inches of sand or compost or a mixture of the two.
Mow any dead vegetation as short as possible.
Seeds: Seeds, purchased from a local source, usually will be better adapted to our area. They should come with instructions on how to treat the seeds or they may be already treated since some seeds require special treatments. They may require a different planting scheme from that given above because some seeds require light exposure for germination. There are specific guidelines that need to be followed for collecting seeds in the wild.
Lightly rake the area. Raking deeper than ½ inch will encourage weed seeds to germinate.
Hand broadcast the seeds over the area. If you are using a mixture be sure they are properly mixed. Commercial wildflower mixtures contain flowers not native to the area so mix your own.
Lightly rake the area again to assure good seed-soil contact.
Spray the area with water.
Care: Water as needed to keep the area moist until seedlings have a couple of true leaves. There is no need for fertilizer. Of course, avoid foot traffic.
Avoiding Problems with City Ordinances
Here are several suggestions for avoiding problems with those people that think only a well manicured lawn is acceptable. Actually, you are trying to defend yourself from the authorities that will be responding to the complaints of the lawn crowd.
Do not have any plants that are noxious or allergenic.
Do not violate any height restrictions near roads.
Take care not to violate any easement requirements.
Make the area look like a garden including hardscape.
Keep records of what is present and their care.
Keep records of all interactions with authorities.
Keep a picture record of what your garden looks like through the seasons.
