Is it OK to use ericaceous compost for all plants?
Can I use ericaceous compost on all plants? Ericaceous compost is ideal for acid-loving plants so you should use it for them solely and use neutral or alkaline soil for other types of plants.
Is ericaceous soil low pH?
Acidifying garden soil will lower its pH so that ericaceous plants such as camellias, blueberries, heathers and rhododendrons can grow.
How do you make soil more ericaceous?
Begin your compost pile with a 6 to 8 inch (15-20 cm.) layer of organic matter. To boost the acid content of your compost, use high-acid organic matter such as oak leaves, pine needles, or coffee grounds. Although compost eventually reverts to a neutral pH, pine needles help acidify the soil until they decompose.
What plants do not like ericaceous?
What is ericaceous compost? Ericaceous compost is an acidic compost suited to growing lime-hating plants such as rhododendrons, azaleas, camellias, calluna and various other acid-loving plants. The meaning of the word ‘ericaceous’ directly relates to the definition of plants in the Ericaceae family.
What plants benefit from ericaceous compost?
Which plants need ericaceous compost? The largest groups of lime-hating or acid-loving plants are rhododendrons (including azaleas), camellias and pieris. Blueberries do best in ericaceous compost, along with summer-flowering heathers (Calluna), Fothergilla, Gardenia, Gaultheria, Kalmia and Leucothoe.
Can I use ericaceous compost for Acers?
Using ericaceous compost for acers will promote healthy growth and sufficient mineral uptake for health. Check the leaves for signs of over-exposure to the sun- Acers need light but do best under a thin canopy. Acers need damp (but not wet) soil conditions, so a loamy soil with good drainage is perfect.
What can I use instead of ericaceous compost?

Can ericaceous compost be used for roses?
Roses thrive in slightly acidic soils so they can absorb the nutrients they need to thrive and produce a beautiful display of flowers. If the soil is too alkaline then adding ericaceous compost and plenty of organic material will balance the soil and result in the desired more neutral or slightly acidic soil condition.
Can I plant seeds in ericaceous compost?
The seeds should germinate regardless. Ericaceous compost may not be ideal afterwards because it will affect the availability of nutrients, but it should not be immediately fatal. If the seedlings seem to be suffering then you can transfer them to better compost, or perhaps apply a little lime.
Can I plant begonias in ericaceous compost?
They will grow much better in a peat based ericaceous compost than a soil based one and are not at all easy in peat free mixtures. This is because they want permanently moist compost that’s well drained so never waterlogged.
Do hydrangeas need ericaceous compost?
Adding compost to alter the pH of the soil will determine the color of the blooms you get. If you want or have blue hydrangeas you need ericaceous compost. For other colours and white normal multi-purpose or shrub compost is fine.
Which fertilizer increases the acidity of soil?
Nitrogen Fertilizers Nitrogen sources — fertilizers, manures, legumes — contain or form ammonium. This increases soil acidity unless the plant directly absorbs the ammonium ions. The greater the nitrogen fertilization rate, the greater the soil acidification.
Do Tea bags make soil acidic?
It’s important to know that not all plants like tea leaves, whether poured over them directly or via compost you’ve made up – the tannic acid in them can lower the soil’s pH and increase its acidity.
Is multi purpose compost alkaline?
The general assumption is that all multi purpose composts are pH neutral. If we want a compost that is specifically acidic, to match the needs of acid-soil desiring plants, then we need to look at a type of compost known as ericaceous compost.
Do Camellias need ericaceous compost?
How to plant camellias. Camellias need acid or ericaceous soil, with a pH of 5.5-6.5. If the pH is neutral in your area, you can make it more acidic by adding composted bracken (available mail order), homemade leaf mould or composted pine needles to the planting hole, then mulching with them too.

Some of the most beautiful plants are acid-lovers, such as Azaleas, Rhododendrons and Gardenias.
Is clay soil acidic or alkaline?
Most types of soil, including clay, which tends to be slightly alkaline, will benefit from the addition of organic matter.
What is the best compost for Acers?
Acer palmatum varieties adapt well to life in a pot providing the roots are kept moist and have a good drainage and aeriation. Crocks in the bottom of the pots are a good idea. Loam based compost such as John Innes No 2 is best together with a bark mulch to help avoid water loss.
Why are my Acer dying?
Scorch happens whenever water is lost from the leaves more quickly than the roots can take it up. A wide range of environmental factors can cause this such as frost, drought including under-watering, waterlogging, drying winds, hot sun and even salt-laden winds in coastal areas.
What is the best compost for Japanese Acers?
Japanese maples are ideal plants for growing in containers. Plant in a John Innes No. 2 potting compost or a peat-free ericaceous with 25% added sharp sand, which gives good drainage. Keep the compost moist, but not soaking wet, and feed in spring and early summer with a slow-release fertiliser or liquid feed.
