65 Plants You Can Grow in Clay Soil

If your soil is sticky when wet or cracks when it’s dry, chances are you have clay soil. But don’t worry; plenty of plants will thrive in this type of soil.

However odd it may sound, clay is one of the best soil types for your garden. Its particles are smaller than those in sand, silt, or loam [1]. This unique quality makes it great for plant growth.

Overall, clay soil is great for certain plants because of its water-holding capacity and ability to hold onto nutrients. With proper care, you don’t need to use as much irrigation or fertilizer.

What about Hydrangeas?

The best soil for your hydrangea drains well and is loamy and fertile. If you’ve got clay soil, though, no worries. You can still supply your plants with what they need by amending the soil with compost or other organic materials.

Issues With This Soil Type

Clay soil may not be ideal for many gardeners, but some plants still thrive in it.

The worst thing about clay is that it gets waterlogged due to poor drainage. This can be a problem for some plants, limiting oxygen to their roots and hindering growth.

This soil type is also slow to warm up in the spring, compacts easily, and is heavy to dig, but it still works well for some plants.

Improving Heavy Clay Soil

You can improve most clay soils with time and effort. However, the most important issue to tackle is bad drainage, especially when standing water is present.

Organic Matter

Get your hands dirty and turn that soil over, incorporating lots of organic matter. Doing so will significantly improve the quality of this soil type.

Coarse grit, compost, manure, and leaf mold are all great options for getting started. Spread two to three inches of any of these materials and fork them into your garden bed.

Garden Lime

You can also improve this soil type with some calcium. This will help the clay particles form clumps and improve drainage.

However, note that this technique works best on acidic soils. If you’re not sure of your soil’s pH level, pick up a testing kit from your local garden store or get one online.

Gypsum

Who knew that gypsum could do so much for your lawn and garden? Not only does it improve soil structure and relieve compaction, but it also adds essential nutrients like calcium and sulfur. And unlike lime, it doesn’t affect your soil’s pH.

Moreover, add some gypsum to your garden to keep veggies such as tomatoes and bell peppers healthy and free from blossom-end rot. This will help ensure they get enough calcium to prevent this disorder.

Takeaway

Clay isn’t just for mud pies. Many plants do very well in it. Sure, it can be dense and heavy, but it’s also incredibly fertile.

Clay also holds water well, so your plants will never suffer from drought. If you choose the right plants, they’ll thrive in clay soil.
