Biennial flowers - a game-changer for clay soil
Got clay soil? Fret not! Embrace its nutrient-rich benefits with these eye-catching and easy-to-grow biennial flowers perfect for your garden.
"Biennials are a gardener's gem, especially when it comes to clay soil," says Kate Turner, a Miracle-Gro horticulture expert. "Cheap, colorful, and easy to propagate, they're ideal for a cutting garden, delivering delightful scents and blooms year after year."
A seasoned grower with over 20 years at Jacksons Nurseries, Hayden Salt shares his passion for horticulture and insights into the best plants for clay soil gardening. Read on to unlock the secrets of gorgeous, flourishing gardens despite the challenges clay soil may present.
Our Test at Home:Wondering what soil type you have? No fancy tools or trips to the garden center required! Take a handful of moist soil, roll it into a ball, then try to flatten it into a ribbon. If it holds together and feels smooth, it's clay. Don't know your sand from your loam? Worry not; our simple test has got you covered!
Tackling the Main Complaint: DrainageThe biggest downside of clay soil is its poor drainage, leading to potential waterlogging, root rot, and compaction issues. But all is not lost; here's how to tip the balance in your favor.
"Regular mulching is the key to improved clay soil for gardening," advises Kate. Fill your garden beds with organic matter like compost, well-rotted manure, or bark chips – Miracle-Gro's Border Booster is an excellent option. No need to dig it in – leave a generous layer on top and let the magic of worms do the hard work. Just remember not to work the soil when it's wet to avoid creating solid, unsightly clumps!
Jacksons Nurseries: Friendly Staff and Mayan Gold"Clay soil often gets a bad rap, but it's not all bad news," says Hayden Salt at Jacksons Nurseries. Yes, it can be heavy and slow to drain, but it's also rich in essential minerals that feed plants like modern-day Mayan gold. With careful plant selection and appropriate care, you can unlock clay soil's benefits and cultivate a thriving garden.
Choosing the Best Biennials for Clay Soil"Biennial plants that grow well in clay soil include foxgloves, sweet william, dianthus, hollyhocks, wallflowers, forget-me-nots, campanulas, and violas," shares Julian Palphramand, Head of Plants at British Garden Centres. Follow Hayden and Julian's recommendations to capture color and life throughout your garden despite your clay soil worries.
1. Foxgloves (Digitalis)"Thrive in clay soil as long as it's not waterlogged," says Hayden. A tall, striking addition to any garden, foxgloves will add height and bloom in their second year. For improved drainage and root spread, sprinkle grit, organic matter, or compost in the soil when planting. Raised beds are another option for those dealing with particularly heavy clay soil.
2. Sweet William (Dianthus barbatus)Great for color and scent, sweet williams handle clay soil well and provide pollinators with a tasty treat. Properly drain clay soil, conserve water during dry spells, and ensure your plants receive full sun or light partial shade to promote healthy growth and abundant blooming. Sweet William varieties like "Sweet Mixed" and "Rockin' Red" are readily available at Dobies and Thompson & Morgan.
3. Angelica ArchangelicaStand out from the crowd with the impressive Angelica, growing up to 2 meters tall. Sow in early winter for a growth spurt the following year. Attract bees and consider using this biennial in your borders for a striking wow factor. Striking Angelica options are available at Crocus and Sarah Raven.
4. Hollyhocks (Alcea rosea)These classic cottage-garden plants adore the nutrient-rich conditions that clay soil offers. Plant hollyhocks in early summer or autumn and allow them to bask in full sun to support their growth and prevent them from wilting due to shaded areas. Proper mulching, such as with bark or compost, is vital to retain moisture, deter weeds, and support the plants while they develop strong roots in clay soil.
5. Forget-me-nots (Myosotis)Add a splash of color with forget-me-nots, which thrive in partial shade to full sun and are happy in boarders, and self-seed readily. To improve clay soil structure and drainage, integrate well-rotted organic matter, sand, and grit. Sow forget-me-nots directly into the ground and appreciate their dainty blooms. Varieties like "Mixed Forget-Me-Not" and "Marginal Aquatic" are just a few options from Thompson & Morgan and Suttons.
6. Wallflowers (Erysimum cheiri)Early-flowering and surprisingly adaptable, these fragrant biennials bring a much-needed splash of color during the spring season. Sow from early spring to summer for blooms during the following year. Try out distinct varieties like Golden Gem from Thompson & Morgan or Orange Bedder on Amazon.
7. Sweet rocket (Hesperis matronalis)Another pollinator-friendly biennial with a pleasant scent and wonderful as a cut flower, sweet rocket is easy to grow and serves as one of the best plants for attracting bees. Scatter seeds in the spring season through summer and enjoy flowers the following year. Good mulching practices with compost and well-rotted manure will improve soil structure; avoid walking on wet clay soil to prevent compaction.
