An inadequate diet may make a Hydrangea’s style difficult. However, if you’re the type of gardener that favors natural techniques, you might be thinking whether all of those specialty fertilizers you see online are actually necessary. Can you use compost or other natural fertilizers to grow hydrangeas?
Yes, it is the answer. Compost, whether purchased or prepared at home, will help hydrangeas grow and thrive since it is nutrient-rich and improves soil drainage. Most Hydrangeas respond well to all-purpose compost, but ericaceous compost is preferable if you want your Mopheads or Lacecaps to produce blue flowers.
The fact that you can make compost in your own backyard is arguably its best feature. Simply gather the ideal mixture of kitchen and grass scraps and spread them out for your neighborhood worms and microorganisms. Your hydrangeas will receive a ton of nutritious yield from them.
Should I use ericaceous compost for hydrangeas?
For hydrangeas to change from pink to blue, the soil must be acidic and contain salts of either aluminum or iron.
We all learned in chemistry classes in school that distilled water has a neutral pH of 7. However, in horticulture, a neutral pH is typically categorized as 6.5. Any soil with a pH below 6.5 is considered acidic, and any soil with a pH above 6.5 is considered alkaline. A pH testing kit can be used to check the pH of your soil, and Greenshutters Nurseries & Garden Centre has these on hand. The inexpensive pH meters that are available are often not precise, so I do not advise using them. Often, seeing surrounding gardens and the local plant life is a simpler approach. It’s likely that your soil is acidic if nearby Rhododendrons, Camellias, and Pieris are flourishing in the soil.
Peaty or sandy soils are typical of acidic soils. Clay soils are typically not highly acidic. Chalky soils have a high pH. By incorporating Irish moss peat or ericaceous compost, you can increase the acidity of your soil. Ericaceous compost has an acidic pH range of roughly 5.0 to 5.5, while regular multifunctional compost has a pH range of 6.0 to 6.5.
Irish moss peat is particularly useful for mulching since it has a pH of about 4.0, which is much too acidic for most plants to thrive in. However, when combined with neutral or alkaline soil, it lowers the pH of the soil. Once a year, mulch with Irish moss peat and let the worms to work the peat into the soil to maintain the acidity of the soil around a plant.
As an alternative, hydrangeas can be grown in containers. Although hydrangeas can thrive in both multifunctional and ericaceous compost, it is recommended to plant them in the latter if you want them to turn blue.
If your soil is deficient in aluminum or iron salts naturally, you can easily increase them by putting Hydrangea Colorant into the soil. People claim that adding rusty nails to the soil or compost will turn hydrangeas blue; however, as I have never tried it, I am unable to confirm if this is true or false. On the other hand, Hydrangea Colorant is a combination of Iron Salts and Aluminium Sulphate. When potting or planting, it can be added to the soil. For established plants, you can also dissolve the Hydrangea Colorant in water and give your hydrangeas a weekly drink during the growing season (March to September). Your light pink kinds will become blue if you do this, while your dark pink varieties will turn mauve-blue.
Grow your hydrangea in neutral or alkaline soil, though, if you want it to stay pink.
What kind of soil works best for hydrangeas?
Friable, loam soil and soil with a high organic content are ideal for hydrangea growth. The soil must have a light structure that drains properly and be able to retain rainwater. You won’t need to add any fertilizer to the soil if it is nutrient-rich.
While bigleaf hydrangeas can tolerate both acidic and alkaline soils, doing so will change the color of their blossoms (Hydrangea macrophylla).
Which acidic compost is the best?
The best compost to use for these acid-loving plants is ericaceous. For all kinds of acid-loving plants, our Westland Ericaceous Planting & Potting Mix is the best choice.
Can Tomorite be used to fertilize hydrangeas?
Tomorite is rich in potassium, which is needed for flowering and fruiting.
Although I would wait a little before administering it to your hydrangea, potash will aid in its flowering.

Do hydrangeas require specific types of soil?
In dappled shade that is neither very sunny nor overly dark, wet, well-drained soil is excellent for hydrangeas. Avoid sites that face south, especially if the soil is quite dry. Grow Hydrangea anomalasubsp. petiolaris, a climbing shrub, in an extremely shady area like a north-facing wall. Avoid planting in a frost pocket and plant away from strong winds in the spring since the tender new growth is vulnerable to frost damage.
Most soil types, including alkaline and acidic soil, are suitable for hydrangea growth. The color of some types’ flowers will vary depending on the pH of the soil. If the soil is acidic, some plants that typically produce pink flowers will instead produce blue ones.
When to plant hydrangeas
Hydrangeas grow best in the spring or fall when the soil is warm and moist. It is possible to plant in the summer, but you must monitor the soil’s moisture content.
How to plant hydrangeas
If your soil is thin, bulk it up with moisture-retaining organic matter before planting hydrangeas because they thrive in damp soil. A good hour or so before planting, thoroughly water the plant. A hydrangea should never be planted any deeper than it was in the pot. Well with water. After planting, add a layer of mulch. Leaf mould is preferable, but compost or well-rotted manure can also work. Throughout the plant’s first spring and summer, make sure it gets plenty of water.
Train climbing hydrangeas initially onto galvanized wires before planting. They have roots that attach to themselves, so after a season of growth, they will find their own way.

What plants flourish in ericaceous compost?
You want to plant some flowers that need an ericaceous compost, but you have no idea what that word means or what it does. You’re surely not the only one who thinks so, though!
There are quite a few plants that, for a variety of important environmental reasons, can only flourish in this kind of compost. That is to say, you might be setting yourself up for failure if you try to produce Camellias, Blueberries, or Heather before first determining your soil type.
Nevertheless, don’t panic! We have all the details you require about ericaceous compost and how it will benefit particular plants in your yard.
What is ericaceous compost?
The plants that like to grow in it gave the soil type ericaceous, which is more acidic, its name. The Ericaceae family is the name given to them. This indicates that in order to support their growth, these acid-loving plants require a more acidic compost. Ericaceous plants are also referred to as lime-hating plants since they do not thrive in soils that are high in alkalinity.
Which plants need an ericaceous compost?
Rhododendrons, Azaleas, Camellias, Hydrangeas, Holly, Fern, Gardenia, Aster, Magnolia, Pachysandra, Lupine, Pieris, Viburnum, Bleeding Heart, Japanese Maple, Juniper, Blueberries, Raspberries, and Cranberries all require an ericaceous compost to aid in growth. There are many more, so be careful to investigate the kind of compost your plant need!
Why do these plants need ericaceous compost?
Ericaceous plants generate yellow leaves when grown in alkaline or lime soil. Chlorosis brought on by lime is the medical term for it. They typically die because they don’t grow or blossom well. The primary cause of this is that they require iron and other soil nutrients, which become insoluble or “locked up” in the soil when the pH is high and prevent the plants from absorbing them.
It could be simpler to cultivate these plants in pots or tubs if your soil is alkaline.
How should I care for and grow my ericaceous plants?
Consider growing your plants in a sizable pot or container that is loaded with ericaceous compost. The container is necessary so that you can later position your plants according to their demands in the appropriate region of your garden.
The majority of Ericaceous plants cannot be in direct sunlight because the exposure will cause their blossoms to turn brown. They are hence ideal for growing in shade.
Make sure to feed your plants with a sufficient fertilizer, and you’ll need a special ericaceous plant feed for the compost. A continuous release plant food is an alternative that can be applied once and nourish plants for six months.
Ericaceous plants also require constant watering, particularly in the summer. Therefore, be sure to water your plants once a week and mulch the soil well to keep the moisture in.

Which alternative to ericaceous compost is available?
Verify that your ericaceous compost is free of peat as well; the label should indicate this. If finding peat-free ericaceous compost proves difficult, prepare your own. Use composted bark, bracken, or a combination of the two as the foundation and then mix three parts by volume of sharp sand or perlite with one part without any added lime.
Do all plants benefit from the usage of ericaceous compost?
Compost that is specifically designed for growing ericaceous plants is an acidic sort of compost. These can include plants that do poorly in alkaline soil, such as heathers (the word “ericaceous” is derived from the Latin word for heathers), camellias, and rhododendrons.
Ericaceous compost is comparable to what?
Because they can’t absorb certain minerals in alkaline or limy soil, some plants that have developed from woodland, mountainside, or heathland, require soil that is acidic or neutral. The term “ericaceous” refers to the family of plants known as Ericaceae. The improper type of soil causes plants to quickly display signs of nutritional insufficiency, particularly a lack of iron and other trace elements. Yellowing leaves, or “lime-induced chlorosis,” are the main sign. This stunts growth and produces subpar results.
Which plants need ericaceous compost?
Rhododendrons (including azaleas), camellias, and pieris are the three main plant species that dislike lime or thrive in acidic environments. Ericaceous compost benefits blueberries, summer-flowering heather (Calluna), Fothergilla, Gardenia, Gaultheria, Kalmia, and Leucothoe the most.
What’s in ericaceous compost?
Peat has traditionally been the principal component of many potting composts, especially ericaceous compost. Peat is naturally acidic, but as people become more aware of the harm that peat extraction does to the environment, numerous great peat-free substitutes have been created. In the UK and Europe, lowland bogs are the primary source of peat harvesting. Peat bogs are home to a variety of endangered wildlife species and store enormous volumes of water and carbon. Therefore, destroying them to collect peat worsens climate change, endangers biodiversity, and raises the possibility of localized flooding. The use of peat in horticulture and composts is being phased out, but progress is being made slowly.
A few ericaceous composts without peat are on the market; they contain things like composted bracken or bark, coir (coconut fiber), and wool. Additionally, you can purchase Moorland Gold, a compost formed from recycled peat that has been diluted in lakes and reservoirs.
How can I encourage my hydrangea to bloom more?
Early spring or mid-July through late summer are the blooming seasons for hydrangeas. The methods for extending hydrangea blossoms’ life and producing more of them are discussed below.
Plant the hydrangea where it will receive morning light and afternoon shade, keep the soil continuously moist, and treat it in the spring with a fertilizer that is well-balanced to encourage more flowers. To encourage more blossoms, don’t prune your hydrangea too frequently. Hydrangeas bloom on the growth from the previous year.
Continue reading to find out how to lengthen the time that your hydrangea blooms as well as my personal pick for the best fertilizer for hydrangeas to enhance blossoming.
How can acidic soil be created for hydrangeas?
Like coffee itself, coffee grounds have an acidic pH. The acidity of the soil around hydrangeas is increased by mixing in dried coffee grounds, which enhances the hydrangea’s capacity to produce blue and its capacity to absorb aluminum from the soil. With a pH test kit, track the soil’s pH over time; a range of 5.2 to 5.5 is ideal for blue flowers. Coffee grinds occasionally scattered on the soil’s surface or placed there will slightly raise the acidity level.
