Do I Need to Feed my Garden?
When you go into any garden centre in the UK, you’ll be ambushed by products all proclaiming they make your garden happier and healthier. Hundreds, if not thousands of types of plant feed, everything from grass feed boasting greener lawns to pellets that will give you vibrant rose blooms worthy of the Chelsea Flower show. You’ll also find a whole host of blogs on the internet telling you what to feed each plant if you want that perfect garden.
But here’s the thing. You don’t need all of that. Most planted gardens don’t need feeding at all, and certainly not all the time. So today we’re going to go over when you do and don’t need to feed your garden, and how to tell.
When You Don’t Need to Feed
In your regular day-to-day gardening, you shouldn’t need to do much feeding. If everything is growing well, then there’s really no need to start throwing fertiliser around just because spring has arrived. Healthy plants in healthy soil are generally very good at looking after themselves. Think about what happens in a natural environment. Leaves fall, plants die back, roots decompose and all that organic matter eventually returns nutrients to the soil. Your garden might be more carefully designed than a woodland or meadow, but the basic principle is the same.
This is one of the reasons we’re such big fans of mulch and organic matter. Rather than constantly giving plants a quick hit of nutrients with feed, you can support the soil itself and allow it to do the job it’s supposed to do. And after all, too much of a good thing can be harmful too. Overfeeding your plants can encourage lots of soft, leafy growth that’s more susceptible to pests and disease, and the excessive nutrients can upset the balance of the soil. So before your reach for the plant food, have a close look at your garden, and if your plants are growing as they should, put the bottle back on the shelf.
When You Do Need to Feed
That being said, there are a few areas you may need to feed your plants. For example, container plants. They have a finite amount of compost to grow in, and unlike plants in the ground their roots can’t keep extending outwards in search of more nutrients. And every time you water them, nutrients can also be washed out of the compost. That means that plants in pots will generally need more help, particularly through growing season.
Similarly, newly planted plants also benefit from having good-quality organic matter incorporated into the soil when you plant them. But even here it’s not about giving them a constant supply of fertiliser, it’s about getting the soil and growing conditions right to nurture that growth.
Then there are plants that are just hungry! Some plants, like fruit, vegetables, roses and heavily-flowering plants need extra nutrients when they’re actively growing. Which means they’re using more resources from the soil and may need help replacing them.
In all of these cases, you’re feeding because there’s a genuine need for more nutrients, not just because you think you should. If a plant looks unhealthy, don’t automatically assume it needs fertiliser. Yellow leaves, poor growth and a lack of flowers can have plenty of causes, from waterlogging and drought to pests, disease or simply being planted in the wrong place. More food won’t solve any of those problems, and might even make them worse!
How to Make Sure You Have Healthy Soil
If you really want to improve the state of your garden, you don’t need to fuss about food. You need to understand your soil and invest time in making it healthier. After all, good soil is the foundation of a healthy garden. It provides plants with nutrients, hold water and allows air to reach the roots. It also supports a huge ecosystem of microorganisms, fungi and invertebrates that you probably don’t realise are there, or how useful they are. And the best way to look after your soil is to feed it, rather than the plants.
You do this by adding organic matter like:
- Garden compost
- Homemade compost
- Leaf mould
- Well-rotted manure
All of these help improve soil structure and gradually release nutrients as it breaks down. It’s a much more natural way of supporting your garden than constantly reaching for a bottle of liquid feed.
Mulching is particularly useful for borders. Adding a layer of organic matter on the surface helps retain moisture, supress weed and protect the soil, while gradually breaking down and returning nutrients to it. Another way to support your soil is to stop chasing the immaculate. Fallen leaves, spent plants and other organic material are all an important part of the nutrient cycle, rather than mess to clean away.
That’s the best way to feed your garden. Not with fertilisers and bottled plant food, but by carefully curating and maintaining the quality of your soil. Pay attention to how your plants are growing and get to know your soil, and your garden will always thrive. And if you’re not sure how to do that, or need some help maintaining it, we are more than happy to help. Just get in touch with CMA Garden Design today.
