If your soil is sticky when wet or cracks when it’s dry, chances are you’ve got clay soil. But don’t worry, there are plenty of plants that will thrive in this type of soil.
However odd it may sound, clay is one of the best soil types for your garden. Because its particles are much smaller than other soil types like sand, silt, or loam [1], its distinctive qualities make it ideal for plant growth.
Overall, clay soil is great for certain plants because of its water-holding capacity. Plus, it holds on to nutrients very well. With proper care, you don’t need to use as much irrigation or fertilizer.

What about Hydrangeas?
The best soil for your hydrangea is one that drains well, is loamy, and is 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 the ideal choice for gardeners, but there are still some plants that don’t mind growing in it.
The worst thing about it is that it tends to get waterlogged. This can be a bit of a problem, hindering plant growth and may even cause root decay.
This type of soil is also slow to warm up in 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. This is especially true when standing water is present.
Organic Matter
Get your hands dirty and dig that soil over deep, incorporating lots of organic matter as you go. Doing so will improve the quality of this soil type greatly.
Coarse grit, compost, manure, and leaf mold are all great options to get started. Spread out two to three inches of any of these materials and fork it into your garden bed.
Garden Lime
You can improve some clay soils with a little calcium added in. This will help the clay particles form clumps and improve drainage.
However, note that this technique works best on acidic soils. So, 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 pH.
Moreover, if you want to keep veggies such as tomatoes and bell peppers healthy and free from blossom end rot, add some gypsum to your garden. This will help ensure that they’re getting enough calcium, which is essential for preventing 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 really well, so your plants will never suffer from drought. If you choose the right plants, they’ll thrive in clay soil.
