Where to Plant: Choose a spot with as much sun as possible. We consider full sun at least 6 hours daily. For wildflowers, full sun is best. Most all soils are acceptable -- if any plant has grown in the spot, it should support wildflowers, which are tough and will adapt to the soil you provide for them.
When to Plant: The optimum time to plant wildflower seed in your area depends on your climate and rainfall patterns, as well as the species you are planting. In cooler climates; plant annuals, perennials or mixtures of annuals and perennials in spring, early summer or late fall. In milder or warm climates; plant wildflower seed during the cooler months of the year, fall through spring. Perennials can be sown spring, summer and fall. If planting perennials late summer be sure to allow 10 weeks growing time before plants go dormant for the winter months.
Spring planting: when there is no further chance of a killing frost, meaning that your night time temperatures are maintaining 45 degrees and above.
Summer plantings: annuals or mixes containing annuals can be planted through mid-summer. Depending on your climate you want to insure that you have enough time to enjoy all the annuals in your growing season. Perennials can be planted through the summer up until 10 weeks before your cold weather sets in.
Fall plantings: in areas with freezing weather, a fall planting must be after a killing frost when your daytime temperatures are maintaining 45 degrees and below but before the ground freezes. In other words, when you are sure cold weather has set in. Killing frosts usually happen at 28 degrees Fahrenheit. Fall plantings in cooler climates are dormant plantings and should be late enough so that the ground temperature is low but the ground is not yet frozen. Seeds must remain dormant – the seeds will germinate in spring. In areas of no frost, plant as your rainy season begins. It is never too late to plant – just ask us for details on how and what to plant!

Remove all existing growth, either by hand , roto-tilling, rough or power raking. Till only deep enough to remove all old roots. Deep tilling may bring up dormant weed seeds lying beneath which will compete with your flowers. If you want to be sure your soil is “weed seed free”, you’ll have to till, wait for the crop of new weeds to grow, usually one to three weeks and then do one of two things; kill them down with one of the safe, non-residual method of using white vinegar; or to till again as in step one. If you use the vinegar method, then once the weeds are dead, rake them out and seed your wildflowers without roto-tilling again. If using the roto-till method, you can seed after the second or third tilling. For those of you that wish to use an herbicide, please read the label for any detrimental effects it may cause. If you choose to use this, use the same steps as if using the vinegar.
About Fertilizer: When you choose to plant wildflowers there is usually minimal weeding done…and fertilizer will encourage the weeds and grasses. Fertilizer is not necessary for a great wildflower garden or meadow. (No one fertilizes in the wild or along roadsides), but if you want this extra boost for your flowers, fertilize only where you are willing to weed.
Sowing: Once your soil is prepared and free of previous growth, it’s important to sow immediately. (If you let time go by between preparation and spreading your seed, you’re giving possible weeds an advantage over your wildflower seed). You can use a hand crank seed sower, but most simply scatter the seed by hand. If you want to be sure to get good, even coverage, divide your seed into two roughly equal parts, in two buckets or cans. Then add clean sandbox sand to both halves, roughly 4-5 parts of sand to 1 part of seed. The sand does two things: It “dilutes” the seed, making it easier to sow evenly, and since it’s light-colored, it shows you “where you’ve been” on the dark soil as you go. Next, sow one bucket’s mix over your whole area. Then go back in the opposite direction and do the same with the second bucket. This way, you should have even spreading and no bare spots. Once seed is sown, do not rake or cover it in any way. If you can, use a lawn roller or lay down a large board and walk on it to compress (squash down) the seed into the bare soil. Remember, some of the seed you’re sowing is tiny; even the lightest covering of soil can stop it from germinating. Keep your new seedbed moist until seedlings are about 6-8” tall. After that, they should be self- sufficient; however watering during droughts will keep your flowers blooming.
