Choosing the best soil for roses can seem complicated at times.
With so many soil types and amendment materials to choose from, it is understandable how a newcomer can feel overwhelmed.
We all want what’s best for our plants, which is why we made this ultimate guide on the best soil for roses.
Soil Types
There can be a lot of discourse over different types of soil out there.
Let’s take a look at three very common soil types: clay, sandy, and loamy.
1. Clay Soil
Clay soil is primarily made up of small grains that group together in tight clusters.
It is very compact and heavy.
This soil is not ideal for most plants due to its nature.
Roots find it difficult to develop under the suffocating heaviness of clay soil.
Water drains very slowly in clay soil and there is not much room for proper air circulation.
2. Sandy Soil
Sandy soil contains larger particles compared to clay soil.
It is very well-draining as opposed to clay soil.
However, sandy soil does not retain moisture well. As a result, it requires more frequent watering in order to keep up with its rapid drainage.
Not only that, but sandy soil also tends to be lacking in necessary nutrients for plants to thrive and produce flowers.
3. Loamy Soil
Loamy soil is the happy compromise of these soils.
It contains either medium-sized particles or a mixture of small and large particles.
If you were to put all the soil types on a scale, then loam would be right in the middle in terms of drainage, moisture retention, and airflow.
Discovering What Type Of Soil You Have
When starting out in the garden, you might not know what type of soil you have.
Inspect the soil’s appearance and texture- you can learn a lot just from looks.
Clay soil tends to crack when it is dry. It also has a greasy texture when it is moistened.
Sandy soil won’t crack when dry, but it will feel gritty when it is wet.
You can also determine soil type by how quickly it can drain water.
Dig a hole about 12 inches deep and fill it with water. If the water has yet to drain after 1 hour, then it is safe to assume you have a clay soil.
Determine Soil Depth
After deciding what type of soil you have, you must then determine its depth.
Using a garden spade, make a hole that is about 2 feet deep.
If your soil runs deep, you will be able to effortlessly dig a hole unobstructed.
However, it is likely to hit an obstacle (hardpans, bedrock, or boulders).
If these obstacles prove to be impossible to move, then we highly suggest using a raised bed in order to provide that needed 2 feet of soil depth.
How To Prepare The Best Soil For Your Roses
To prepare the best soil for your roses, you will need amendments.
Amendments will help you personalize the soil based on the roses’ specific needs.
Organic Amendments
Organic amendments are good for just about any soil.
It is made from the byproducts of decomposed animal or plant remains.
Organic materials help soil quality by sitting between the soil particles.
In clay soil (which is very compact) the organic materials act as a buffer between the otherwise tightly compacted clay particles. It helps increase the drainage and airflow of clay soils.
In sandy soil (which is aerated and well-draining, but lacks moisture retention), the organic materials sit in between the sand particles and help the soil retain moisture and nutrients.
The breakdown of organic materials produces a substance known as humus. The humus helps bind particles together, making the soil easier to dig and work within the garden.
Examples of organic materials:
- Peat moss
- Manure
- Sawdust
- Leaf mold
Regardless of the organic material used, it is recommended to add 25% of the volume of the soil prepared.
When adding organic materials to your garden, you should work the soil until the materials are uniformly mixed into the entirety of the planting area.
This is helpful because roots have a preference for growing in uniform soil.
Providing well-blended soil for your rose plants will allow the roots to grow and thrive in an unobstructed environment.
If your soil type is sandy or loamy, you can also add organic materials at the time of planting. Doing so is beneficial to increase water and nutrient retention.
However, the same cannot be said for clay soil.
For clay soil, it is best to use standard garden soil in order to backfill clay soil.
Lightening the backfill soil in this scenario does more harm than good.
The hole will end up absorbing more water at a faster pace.
This will result in the soil holding in much more water and causing the plant to become waterlogged.
Inorganic Amendments
While organic amendments are the most popular option to amend your soil, inorganic products have their place in the garden as well.
Materials such as gypsum and lime can be used to loosen compacted clay soils, for example, but should be used in specific areas depending on the soil’s pH levels.
Gypsum is better suited to help acidify soil pH, whereas lime is best to raise the pH level.
If you are curious about the pH level of your soil, then it is always a good idea to invest in a testing kit.
However, this is not a necessity when it comes to roses, as these plants are often very forgiving when it comes to pH levels.
Many rose growers also enjoy using perlite for its multifaceted uses.
Perlite not only can provide excellent drainage and aeration, but it also has moisture-retaining properties as well.
When To Prepare The Best Soil For Your Roses
When preparing the best soil for your roses, it is best to start early in order to allow the soil to settle down and mellow before planting occurs.
Early preparation can be done months in advance, as soon as you start to plan on planting roses.
If you intend on planting your roses in the autumn, then we suggest prepping your soil in the summertime.
Prepare your soil in the early autumn if you intend on doing a spring or winter planting.
Prepping in advance also allows you to use a wider range of organic amendments.
Take animal manure for example.
When it is fresh, animal manure can actually burn newly planted roses, which is counterproductive to your goals.
Instead, it is advised to work in animal manure to the soil a few months in advance in order for it to sufficiently meld into the soil, therefore posing no threat to the safety of your plants.
Of course, sometimes gardening involves a lot of last-minute decisions and you may need to amend your soil with only a few days to spare.
For short-term amendments, it is suggested to use materials with enough nitrogen to encourage decomposition, or well-rotted materials (leaf mold and compost), or peat moss.
Planting Remedies For Problem Sites
Sometimes simple amendments are not enough to fix drainage issues in the garden.
Remedying problem sites will require some extra work, but will certainly be worth it in the end.
Here are three of the best solutions for planting in problem sites:
1. Raised Beds
Raised beds are the premier way to solve the issue of a leveled garden, or insufficient soil depth.
It will help add both depth and drainage to your soil.
Craft your raised beds so that they will be at least 1 foot above the ground.
Fill the raised beds with organic material and start to blend it with the native soil that was already in the garden.
Allow the soil 2 months in order to settle properly before any planting occurs.
2. Tile-Drained Beds
Tile-drained beds are the answer for a situation where the soil is poorly draining and the garden is on an incline.
You may plant your roses at ground level by installing drainage pipes or tile beneath the garden beds.
After the pipes are properly installed, you may proceed to fill out the garden beds with organic material.
Once again, allow the organic materials to settle for a couple of months before planting your roses.
The water will enter through the pipes and be expelled to another area by draining down the incline.
3. Terraced Beds
Terraced beds are a solution to very sharp inclines.
Similar to the tile-drained beds method, terraces will provide a leveled surface to grow roses upon, while the excess water will be expelled down the incline.
Use a sturdy material such as wood, brick, or stones to build a retention wall.
Always remember to install “weeping holes”, which are simply drainage holes placed at the bottom of the terrace’s wall.
This helps maximize drainage by avoiding excess water pooling at the lowest part of the terrace wall.
Conclusion
Soil is one of the basic foundations of a healthy, happy plant.
The soil you choose for your roses can make or break the future of your plant, so it’s only natural that you’ll want to know everything about it.
That’s why we’re happy to help you when it comes to choosing the best soil for your roses.
