Sandy Soil? These Plants Love it!

Summary

• Coreopsis, daylilies, irises, and lavender thrive in sandy soil with good drainage and only need minimal amendments.
• Water plants deeply but infrequently to encourage deep root growth in poorer soils, preventing dryness.
• Fertilize sparingly with slow-release options and apply mulch for moisture retention in low-nutrient soil types.

Are you looking for plants that thrive in sandy soil? Many gardeners face challenges when working with poorer soil types because it only retains moisture for a short time and lacks essential nutrients. However, plenty of plants flourish in sandy conditions and prefer drier, looser soil.

In fact, there are several advantages to gardening in sand soil types. It tends to be light and less labor-intensive to cultivate, drains well after watering or rain, and warms up quickly in the springtime. However, there are also a few downsides to sandy and other poor soil types. It dries out quickly and is often acidic and low in nutrients. As such, it's helpful to amend sandy soils with organic matter like compost, manure, leaf mulch, or processed bark in early spring before planting.

With some planning and research, you can create a beautiful and thriving garden, even in sandy types of soil!

1 Coreopsis Is Tough and Pretty

Don't let the delicate-looking flowers fool you; this plant is a fighter!

Coreopsis, also called tickseed, is low-maintenance, pollinator-friendly, heat- and drought-tolerant, and deer-resistant!

• These tough plants prefer full sun or partial shade.
• Coreopsis plants are hardy in USDA zones 3 through 9.
• These lovely flowering perennials require well-draining soil with a neutral pH.

Coreopsis plants are not heavy feeders and grow well in relatively poor soil as long as it drains well. As such, amending the soil isn't usually necessary in sandy conditions where drainage isn't an issue!

Water these plants deeply and infrequently, with an average of 1 inch of water per week from rainfall or irrigation. Coreopsis is drought-tolerant and overwatering damages the root system. Fertilize sparingly with a slow-release fertilizer in the spring, as excess fertilizer causes leggy growth and few flowers.

2 Daylily Is Bright and Bold in Sandy Soil

Even in poor soil, daylilies bloom with spectacular color

Daylilies (Hemerocallis) are remarkably hardy and adaptable, growing well in different types of soil.

• These gorgeous flowering plants thrive in full sun or partial shade.
• Daylilies thrive in USDA zones 4 through 9.
• The flowers grow best in well-drained soil with a neutral to slightly acidic pH.

Although they'll grow in relatively poor soil, these plants perform best if you amend your sandy soil with organic matter like compost or manure before planting. Doing so adds nutrients to the soil and helps maintain more consistent moisture levels.

Daylilies are relatively drought-tolerant but grow best with around 1 inch of water per week. Fertilize once in the spring with a balanced, slow-release fertilizer. However, avoid over-fertilization, as it causes excessive foliage growth at the expense of flowers.

Plants may need more frequent fertilization and extra irrigation in sandy soil if you haven't amended it with compost. Additionally, applying 2 to 3 inches of mulch over the soil surface helps to retain soil moisture, insulate plants' roots, and improve soil quality by adding nutrients and organic matter.

3 Iris Is Strong and Beautiful

The iris is no shy violet, it can thrive in sandy soil types!

Known for its distinct blossom shape and color, iris is a favorite in home decor and floral arrangements of all types. These lovely flowers will also thrive in sandy soil and other poorer types of soil.

• Give iris flowers six to eight hours of direct sunlight daily.
• Iris plants thrive in well-draining soil with a neutral to slightly acidic pH.
• These plants are suitable for USDA zones 3 to 9.

It's helpful to amend your soil with organic matter like compost or manure before planting to add nutrients and moisture retention.

Water your irises consistently and deeply, especially during dry periods. However, overwatering often causes the rhizomes to rot. After planting, keep the soil consistently moist but not too soggy. Once the plants get established, allow the top 3 inches of soil to dry out between watering. Fertilize your irises in the spring with a balanced, slow-release fertilizer. A second application after the first flowering is beneficial for reblooming iris varieties.

4 Lavender Is Not a Picky Plant

Multiple types of lavender grow well in sandy soil

Lavender (Lavandula) plants aren't very picky about soil conditions as long as there's adequate drainage. As such, amending sandy soil isn't necessary unless it's too compacted.

• Plant lavender where it gets full sun, meaning at least six hours of direct sunlight daily.
• English lavender varieties are generally hardy in USDA zones 5 through 10.
• In cold regions, they benefit from extra protection from harsh winter conditions using a thick layer of mulch.

Spanish and French lavender cultivars are hardy in zones 7 to 9.

Water mature lavender plants sparingly until their flower buds form. Once every two or three weeks is usually sufficient. During flowering, water once or twice per week. Lavender plants don't usually need supplemental fertilizer, so that's one less thing on your gardening to-do list! If needed, use ¼ diluted liquid fertilizer only once a week to add more nutrients to sandy types of soil.

The best way to water sandy soils is deeply and infrequently. Doing so encourages plants to develop deep root systems. When the roots reach deeper to where there is more consistent moisture, the plants will be more drought-tolerant. In contrast, frequent surface-level watering encourages plants to grow shallow root systems, causing them to dry out faster and be less resistant to drought.

5 Salvia Is Unique and Resilient

Beautiful flowers and foliage for the garden

The small flower clusters, which usually appear in shades of purple and red, grow on twisting and curving stems that give salvia plants a distinct look.

• Grow salvia where it will receive six to eight hours of direct daily sunlight.
• Salvia plants grow best in well-draining, moderately fertile, and slightly acidic soil.
• Avoid overwatering and over-fertilization, as it increases the risk of fungal disease.
• Salvia plants are typically hard in zones 3 through 9.

There are over 900 species of salvia, so be sure to check the zone for your plants to know whether or not they're cold-hardy.

If you amend your soil with compost, additional fertilizer isn't usually necessary for perennial salvias. But, in poor soils or for annual salvia varieties, mix compost or manure into your soil before planting or apply a slow-release fertilizer.

Sandy soil drains quickly, so excess fertilizer leaches out of gardens and into the local watershed. As such, it's best to use slow-release fertilizer on sandy types of soil and mix it in when planting. That way, soil bacteria and underground moisture help break down and disperse the granules more evenly over time.

Talking Dirt-y About Garden Soil

Cultivate a landscape that is both sustainable and low-maintenance.

Plants that prefer well-draining soil and can tolerate dry conditions are best for planting in sandy soil. In contrast, plants that prefer higher moisture levels or have very shallow roots may be difficult to grow in sandy types of soil because the available moisture gets used much faster than in fine-textured soil, like clay.

Growing plants in sandy soil may seem daunting at first. But with the proper plant selection and site preparation, you'll cultivate a landscape that is both sustainable and low-maintenance. By selecting plants suited to sandy types of soil, providing adequate irrigation and nutrients, and using techniques like mulching and composting, your garden will be healthy and beautiful.
