How to Grow Zinnias

If you’re looking to add more color to your garden in 2022, you might want to add zinnias to your seed list! These colorful flowers are some of the easiest annual flowers to grow. They’re also an excellent nectar source for pollinators and are long-lasting cut flowers.

Most of the zinnia seeds you’ll find at local garden stores are Zinnia elegans. At SESE, we also carry a couple of varieties of Zinnia peruviana and Zinnia marylandica. Zinnias provide a lot of variety, so you’re sure to find something to suit your garden’s design, from the spiky-looking blooms of the cactus-flowered zinnia to the dark red double flowers of Red Beauty. 

Prepare a Bed

Zinnias are pretty adaptable, but they need a bed that receives full sun. Though they’ll tolerate a wide range of soil conditions, well-drained soil rich in organic matter is ideal. Spreading a couple of inches of finished compost over the bed and broad forking it can help your plants thrive.

Planting Zinnias

Here in the Southeast, the easiest way to plant zinnias is to direct sow them when all danger of frost has passed, and the soil is around 70°F. Sow the seeds about 1/4 inch deep. Sow a few every 1 to 2 weeks for several weeks to ensure a steady supply of blooms all season. 

Alternatively, you can start them indoors 3 to 4 weeks before your last expected frost. Zinnias should be transplanted when they’re still relatively small, and you should take care to disturb the roots as little as possible.

These showy flowers make excellent companion plants for various vegetable crops, including squash and beans. They attract bees, butterflies, and other pollinators, ensuring good pollination and wasps and lady beetles that feed on pests.

Zinnia Care

Thin zinnias so that they receive good air circulation and sunlight. Depending on the mature size of the variety you select, you should thin your zinnias from 12 to 24 inches apart. Keeping your zinnia bed weeded and consistent watering will encourage your zinnias to bloom more.

Taller zinnias may need support to prevent lodging. You can stake individual plants, grow them along a fence, or let them grow through a suspended flower support netting, fencing, or other similar material. 

If you’re interested in bouquets, you can continuously harvest zinnias. Cutting flowers encourages them to bloom more. If you’re not harvesting cut flowers, deadheading also encourages blooming. You may want to let some spent flowers go to seed, especially towards the end of the season. 

Saving Seed from Zinnias

Zinnias self-seed well, but it’s also quite simple to save seed from them. You can use it to plant new beds the following year, share with friends, or join a seed swap. 

Wait until the flower heads are fully mature, brown, and dry to harvest them. If the petals are still colorful and pliable, the seeds may not have fully matured. 

Harvest the mature flower heads on a dry day. Bring them indoors and pull the flower heads open. The seeds are brown and arrowhead-shaped. 

Allow the seeds to dry on a screen out of direct sunlight for at least a week. When the seeds are fully dry they should snap cleanly in half and not bend. 

Store them in an airtight container, checking carefully for any signs of moisture for the first two weeks. If you see moisture, place them back on the screen and dry them for a longer period.  

Planning a Bird-Friendly Garden

When we think of nature’s helpers in the garden, we often immediately think of bees and butterflies. We tend to overlook birds, but they’re just as helpful to have around. Songbirds like Cardinals, Bluebirds, and Chickadees feed on various garden pests, Ruby-throated Hummingbirds pollinate flowers, and larger birds like Barn Owls and Kestrels feed on voles, mice, and other rodents that can damage your garden. 

Sadly, many bird species are declining. They’re facing the effects of climate change, habitat loss, and pollution. Providing a bird-friendly garden can help your garden be more productive while giving these incredible creatures a helping hand. Here’s how you can plan a bird-friendly garden for next year.

Layout

You might think that birds wouldn’t care about the layout of a garden, but they do! To start with, you generally want to avoid large open expanses. Songbirds are more likely to visit your garden if you add elements of height and cover. These could be shrubs and fruit trees as well as taller patches of annuals and perennials like sunflowers, Joe-Pye Weed, delphiniums, and hollyhocks. 

The exception to this is openings beneath large trees. These can be great spots for owls and hawks to hunt. They’ll perch in trees on the edges of clearings waiting to swoop down on unsuspecting prey. 

Think about creating a bird-friendly garden with patches of different layers. The tallest layer would be mature trees, followed by shorter trees and shrubs and vining plants like grapes or native Trumpet Honeysuckle on large trellises. Next are herbaceous plants like many of the annual vegetable crops, herbs, and flowers we grow, and last is the bottom layer of mulch like straw hay, wood chips, or decaying leaves. These layers provide habitat for perching, nesting, hunting and foraging, and cover from predators. 

Selecting Plants

The best thing you can do when adding plants for a bird-friendly garden is to select as many native species as possible. These are the plants that birds and their prey are well-adapted to using. They’re also generally low-maintenance and tolerant of local conditions.

If you can add trees to your property, they can help birds and other wildlife. Some great options include native hickories and beeches, which provide protein-rich food for birds like Blue Jays and Rose-breasted Grosbeaks. Native cherries and dogwood are also excellent choices because they produce berries that are favorites for many songbirds. Just be sure to research what will do well in your area. A local field guide to native trees or chatting with your county extension agency can be helpful.

Patches of dense, twiggy shrubs, small trees, or hedges are great places for songbirds to seek cover and nest. Native options like Eastern Red Cedar, Southern Arrowwood, and willows work well. Those that do double duty by providing fruit for you and the birds are also great options. Consider raspberries, elderberries, or mulberries.

Herbaceous plants provide seeds for birds, nectar for hummingbirds, and habitat for insects that birds feed on. Great native choices include rudbeckia, echinacea, bergamot, butterfly weed, goldenrod, and coreopsis. You can also help birds by allowing any bolting lettuces to go to seed. Their little seeds are a favorite of species like Goldfinches. Take a look at plants bloom times and plan a garden with something blooming all season.

Other Additions for a Bird-Friendly Garden

Water Features

Birds are also attracted to water sources. Providing a spot in your garden where they can drink, and bath can make your garden much more attractive. Birdbaths are a decent option, but moving water can be more enticing. Consider a birdbath with a bubbler or a fountain. It’s critical to keep this water clean. You may also want to add a partially submerged stone to allow bees and other insects to get water without drowning.  

Houses

While they’re unnecessary for all bird species, birdhouses can help attract cavity nesters. Don’t just grab the first birdhouse you see, though. It’s best if you start by considering what species of bird you’d like to attract. Specific species have specific nesting requirements. Houses may need to be a certain size, a certain distance apart, or hung at a particular height. 

Bluebirds are an excellent choice because they’re helpful in the garden and have lost nesting habitat to invasive starlings. You can make or purchase bluebird houses with a hole that’s 1 1/2 inches in diameter to allow bluebirds in but exclude larger starlings. If you struggle with rodents, you may want to add a larger house with a 5-inch diameter entrance to attract barn owls. 

What to Avoid

  • Don’t use pesticides in your garden. These chemicals harm species like birds, toads, and predatory insects that naturally keep pests in check. Using them can make pest pressure worse over time. Even organic, low-impact products should be used sparingly. 
  • Leave the leaves! Dead organic matter like leaves and small twigs is great for your plants and birds. They provide habitats for worms, pupae, and insects that are essential food sources for baby birds. 
  • Keep natural areas. While not all gardeners have the space, if you have some natural areas let them remain untouched. Leave standing dead trees which make excellent nesting sites. Resist the urge to clean up fallen trees, limbs, and brush. These provide habitat for birds and insects and eventually rot down, adding organic matter back to the soil. 
  • Don’t clean up all your dead plants. We discussed this more extensively in our post, Wildlife-Friendly Garden: Fall Clean-Up, but leaving some dead plant material through the winter is important. Many flowers like echinacea and sunflowers hold seeds for birds, and the stalks may be home to overwintering insects that birds will feed on during the winter. When all the annuals have died back, these standing dead plants provide perches.

10 Unique Heirloom Varieties to Add to Your Wishlist

If you’re a lover of heirloom varieties like we are, chances are you’ve got an eye for the unique. We love adding uncommon plants to the garden that bring with them a touch of whimsy. Here are ten distinctive heirloom varieties to add to your wishlist to make next season’s garden stand out. 

Grandma Nellie’s Mushroom Pole Snap Beans

These pole beans are a true treasure! Just as their name suggests, they taste a bit like mushrooms when cooked. Grandma Nellie’s are a heavy yielder and are ready to harvest in just 56 days. They’re tender when picked at around 5 inches. 

The original seed for this variety came from Marge Mozelisky and was given to her by her grandmother.

Costoluto Florentino Tomato

This uniquely shaped tomato is sure to be a standout! It’s an Italian heirloom from the Tuscan region that bares 8 to 12 oz, deeply lobed, red fruits. It’s great for slicing, sauces, and making stuffed tomatoes.

It’s also a great choice if you live somewhere hot; Costoluto Florentino was one of the most heat tolerant and productive varieties in the 2011 University of Georgia trials. It also did well in the cool wet, summer we had here in Virginia in 2013.

Mrihani Basil

This ruffled basil comes from Zanzibar off the eastern coast of Africa, where it’s used in food and perfumes. Mrihani is excellent tasting, relatively mild, with notes of anise. This basil is relatively easy to grow, slow to bolt and has excellent resistance to Downey Mildew. 

Lion’s Ear (Klip Dagga)

If you like the unusual and unruly, this orange monster is for you! This plant grows large and sprawling, reaching heights of 4 to 10 feet. Lion’s Ear or Klip Dagga starts blooming in late summer, producing nectar-rich, fuzzy flower tubules that leap from sharp, spiky green bracts. These orange flowers are a favorite of hummingbirds and butterflies.

The nectar of Lion’s Ear has a sweet grapefruit taste. The leaves and flowers of this plant have been used in traditional herbal medicine in Africa and India. 

Lion’s ear is moderately drought tolerant and prefers well-drained soils. It’s a tender perennial and may regrow if winter lows are above 20°F.

Balik Hot Pepper

This productive pepper is named for its unique shape. Balik, pronounced BA-luck, means “fish” in Turkish. These peppers have two lobes generally resembling a fish in shape. They are sleek, crunchy, 1 to 3 inches long, and have milder heat than most Jalapeños. The plants grow about 18 inches tall.

White Wonder Watermelon

While it may not look like most watermelons you see, it’s just as good. The creamy white flesh is crisp with a fresh, sweet taste. White Wonder produces high yields of 3-10 lb icebox-size melons. 

They’re rare today, but white-fleshed watermelons were popular in the 1800s. This unique white-fleshed melon is sure to be a hit at farmers’ markets or on the picnic table!

Lemon Cucumber

This unique cucumber produces seven ft. vines covered with crunchy round yellow fruits. Lemon Cucumbers are ready to harvest in about 67 days. Pick them at 1½ in. for pickling or two in. for salads. You’ll love this excellent, never-bitter, old-fashioned cucumber flavor with a hint of nuttiness. 

Wonderberry (Sunberry)

These Garden Huckleberries are an interesting relative of the tomato. They grow like tomatoes, but Wonderberry is more finicky to germinate. The tiny seeds need to keep moist for a much longer period. However, they self sow readily. 

Plant genius Luther Burbank developed this variety. It produces three ft. plants that yield dozens of clusters of dark, ¼ in. berries; each cluster holds 8-12 fruits. Wonderberry’s unique, huckleberry-like flavor makes for intriguing dessert fillings, jellies, and syrups!

Don’t consume the green fruits as they are likely toxic.

Erlene’s Green Cotton

This beautiful, green-colored cotton is a family heirloom from Erlene Melancon in east Texas. Erlene said that she has been spinning green cotton for years and that her grandmother loved using colored cotton in her quilts.

Erlene’s Green produces five ft. tall plants. The fibers are light olive green and can be spun off the seed. Harvest the bolls shortly after they open so that the fiber does not fade in the sunlight. Once it is spun and washed, it turns yellowish-green. 

Watercress

Rich in vitamins and used in salads for mustard-like flavor, this green stands out for the way it grows. As the name suggests, Watercress should be transplanted into a stream of cool, clean water. Alternatively, you can grow it in pots adding fresh water daily or in trays with just enough water to float the crowns. Watercress needs partial shade in hot weather.
