Tips for Planting & Watering Wildflowers In Dry Areas
If you live in a heatwave-prone area where grass lawns typically turn brown in the summertime, wildflowers should be planted in early spring. This will prevent young plants from being exposed to excessive heat during their first season of growth.
Ideally, plant during the rainiest time of year to minimize the need for supplemental watering -- or at least keep the weather nice and mild so that the sun doesn't evaporate the moisture from the soil.
Wildflowers can still be planted in areas where the hose doesn't reach. We've all seen gorgeous, large scale meadows after all! To accomplish this feat, either time your planting with the weather, or plant seeds in fall to take advantage of winter precipitation.
Wildflower seeds and seedlings must stay moist until they are 4 - 6 inches tall (4 - 6 weeks.) While this is true of most seeds (including many vegetable seeds), the difference lies in the fact that wildflower seeds are not buried beneath wet soil. With constant exposure to the sun, they'll need your help staying moist!
Seed Man's Planting Tips: A sprinkler attached to a timer is an easy way to water your planting without disrupting your regular schedule. On exceptionally hot and sunny days, it may prove difficult to keep the seed bed moist throughout the day, so you can give a through watering the next morning. Water your site well before scattering your seed, and/or make yourself available for daytime watering on hot, sunny days.
When seedlings are 4 to 6 inches high, you can start watering less often, with thorough, deep watering. This will help your wildflowers establish deep root systems, which will make the plants more resilient and drought tolerant.
