How to Sow Wildflower Seeds

Gardeners who sow wildflower seeds in the fall may envision a springtime scene of brightly colored blossoms billowing in the breeze with butterflies and bees dancing from bloom to bloom. but sometimes when spring arrives, weeds-not wildflowers steal the show.

The most common mistake when planting wildflower seeds is not getting rid of the existing weed and grass seed that is in the soil and germinate along with the wildflowers. These fast-growing weeds smother the slower growing wildflowers. For a more successful planting, take time to eliminate the competition.

First, choose a site in full sun, To get rid of existing weeds, cultivate the soil 3-4" deep and remove all the weeds. This the the method with the least environmental impact.

The next step is crucial. Soak the soil thoroughly, then wait for the weed seeds to germinate. When they do, lightly cultivate the soil to a depth of not more than 1 inch. Deeper cultivation exposes more weed seeds that will germinate along with the wildflower seeds.

Before sowing the seeds, rake the soil to form shallow grooves. Ensure even distribution of seed by mixing with 4 times its volume of sand and broadcast by hand. Rake the seed lightly into the soil and tamp it for good soil contact. Wait for fall rains to germinate the seeds. You can water to keep the soil moist if rains don’t come.

Next year, when the plants have dried and dropped their seed, .  Be sure to take pictures of your meadow in the spring with the butterflies, bees and birds enjoying it.

Fall Planting ideas

It’s always exciting for me to see the first fall colors of the season. we may not have a show like they do in the the hardwood forests of the east coast but we’re still barbequeing and they’re not. If your garden cries out for a something that you can put a table and chairs under and still have room to play, consider a red maple. Autumn Blaze maples spread to 40 ft. wide and you’ll be enjoying their brilliant orange-red fall color long into the fall season. They need an occasional deep watering like a fruit tree but little pruning.

Take advantage or fall weather to plant cool season flowers.  October is a great month to plant as the plants will have time to become established and start flowering before winter sets in. You’ll be amazed at how much color your plants will produce when you start early. Good choices for this area include iceland poppy, snapdragon, chrysanthemum paludosum, calendula, stock, pansy, viola, primrose and cyclamen.

Citrus & Avocado for the Santa Cruz mts

Late September and you can feel autumn in the air. While our days are still beautiful and warm, nights are getting cooler with less daylight hours. Perfect weather for transplanting or adding new plants to your garden.

Why is this a good time? Cooler air is kinder to plant foliage and soil temperatures are still warm, which creates an excellent environment for new root growth. In the fall many plants and trees ( even broadleaf evergreens ) are entering a period of dormancy. With no need to allocate resources into foliage, plants are transferring all their energy into roots and storing nutrients for the cool months ahead. By spring, the roots system should be well established.

So take advantage of fall planting weather. Decide what changes or additions you want to make in your garden.
Perhaps it’s time to remove lawn from banks or slopes where water runs off instead of soaking in. Replant with more drought tolerant ornamental grasses or perennials.  Picture hummingbirds feeding on beautiful variegated autumn sage, their creamy white and green leaves topped with brilliant red flowers from summer until frost.

If you have a small lawn on flat land and want to improve water absorption and reduce water waste, rake out the thatch that accumulates at the base. Then aerated your lawn in a hollow-tine aerator or power aerator from a rental yard.  This brings plugs of soil to the surface, then rake compost over the hoes and water well.

Now is a good time to plant citrus and avocado. They will fair better during the cold winter months if roots are established.  Remember to give older citrus a good soak every week or so or the fruit will be dry.

If you’ve always wanted an avocado tree there are several varieties that do well here.  The Bacon avocado is hardy to 24 degrees. You can harvest medium sized fruit from November-March. They even produce at a young age and grow to 30 feet tall. Fuerte avocado have excellent flavor. This tree is large and spreading, hardy to 28 degrees and the fruit ripens from November-June. Zutano is another good variety for this area. Mexicola varieties are also very good.
 
These avocados are self fertile for the home gardener. You can expect your tree to live for about which is a lot of guacamole.

If you receive frost of consecutive night during the winter you can easily protect a young avocado or citrus by erecting a simple frame of 1×1" stakes that extends above the height of your tree.  Then drape with a frost blanket or beach blanket on cold night. Don’t use plastic- the cold will go right through it.

Take advantage of this great fall planting weather. Bon appetit !
