The RHS website describes acers as 'easy to grow'. Acers are happy in all soils, even chalky ones. Heavy clay can be a problem as acers dislike wet feet, so be sure to incorporate some organic matter into the hole at planting time. And don't overdo the watering.
Choosing a Japanese mapleJapanese maples can grow to 8m (26ft) in fifty years, depending on growing conditions, but most are small, slow-growing trees rarely more than 1-2m (3¼ft-6½ft) in height – ideal for the smaller garden or a container.
Acers are deciduous trees David and will shed their leaves during the winter months. With regard to new growth now appearing this has been caused to this year's unpredictable weather and the very mild autumn.
Beni hime is a cheery dwarf maple that is among the smallest Acer palmatum dwarfs with red color.
Using Coffee Grounds on PlantsEssentially, Japanese maple plants do not actually require coffee grounds at all. These plants thrive in good soil, and they need rich amounts of nitrogen, phosphorus, potassium and magnesium to grow well.
Japanese maples, or acers, are ideal for pots as they're slow growing and make stunning focal points. They'll eventually need repotting, so don't forget to watch our video on when to repot an acer.
For best results, apply Acer Feed to the soil during planting and then as a top dressing in spring. Rake, hoe or fork into the top surface of the soil, and in dry weather, water well for maximum benefit. As with all fertilisers, store in a cool, dry place. Keep out of reach of children and animals.
The evidence of the (acer) leaf scorch presents itself as drying leaves. In mild cases, you may notice the edges and veins of the leave going brown. The most common reasons for leaf scorch are unfavourable weather conditions, such as drought, high temperatures, hot dry winds and excessive sun exposure.

In an ideal situation Acer palmatum should have a slightly acidic, sandy, well drained soil that does not dry out in summer or become waterlogged in winter. Acers have shallow fibrous root systems which benefit from an annual mulch of organic matter.
Best Acers for Autumn Colour
- Acer Palmatum Chitoseyama. A good choice for a smaller garden, slow-growing and weeping habit, with incredible colours of deepest red and orange in Autumn, when fully grown will be 2 metres high with 3 metres across – fabulous statement tree.
- Acer Sango Kaku.
- Acer Palmatum Shirasawanum Aureum.
- Acer Palmatum Shaina.
Yes, they can. If you have a porch, a patio or even a fire escape, you have what you need to start growing Japanese maples in containers. These graceful, slender maple trees (Acer palmatum) thrive in pots as long as you know how to plant them.
Well-drained, Consistently Moist Soil - Japanese Maple flourish in any well-drained soil except highly alkaline soil. Many gardeners grow them in acidic conditions, where they pair beautifully with Rhododendrons, Camellias, and Kalmias.
I recommend using a slow or controlled release type fertilizer. Commercially known as Polyon or Osmocote, these are the most common and both work very well on Japanese maples.
Add foliage plants such as Heuchera (Coral Bells), Ophiopogon planiscapus 'Nigrescens' (Black Mondo Grass), Ferns with their graceful fronds, Hostas with their smooth leaves, Carex (Sedges), ornamental grasses with bright golden foliage such as Hakonechloa macra 'Aureola' (Hakone Grass), to carry the display over the
It is common for red-leafed maple to have red leaves in spring that then tend to turn green in summer. Environmental factors are usually the cause. Too strong sun or, conversely, too much shade can cause color change. In sun the leaves may scorch.
AAcers will respond very well to pruning. It is best to prune whilst the tree is dormant, so December to February would be an ideal time of year. Make sure to prune back to a bud – this means cutting just above the bud. If you leave any excess wood above the bud, the dieback could become diseased.
Others, such as Acer palmatum, Cotinus, Lonicera, Jasminum and Sambucus, can be removed from the parent plant with a heel, pulling off the stem with a 'tail' of bark from the previous season's growth. The heel is then dipped in hormone rooting compound.
A. Japanese maples do well when carefully pruned so can be planted just a metre from the house. Many cultivars do not grow taller than eight feet and so will fit nicely in a corner next to the house, underneath a window or eve, or beneath a medium to large shade tree.
Originally Answered: Why are Japanese maples significantly more expensive than other types of trees? The biggest factor is that most of them are grown as grafted plants. This adds significant cost to each one as seedlings are much cheaper to produce. That and yes they are slow growing.
Japanese Maples have a reputation for being difficult to grow, but while they have needs that need to be attended to for best growth and color, they are a tough and adaptable plant. There are more varieties than one could count, from dwarf maples for containers to upright trees worthy of a focal point in your garden.
Dig a hole three times the width of the root ball, but not as deep. When you put the tree into the hole, it should sit slightly above the soil line.
Do all Japanese maples lose their leaves? Yes! Japanese maples are deciduous trees. During October and November maples provide a lovely show of fall color. Then in late November, or December, the leaves drop.
Quick tips…
- Keep plants moist and in the shade until planting.
- Soil preparation with organic matter is important, especially if the soil is heavy clay.
- Mulch with 6 inches after planting to reduce the need for frequent watering and protection of their shallow roots.
- Keep pruning of newly planted trees to a minimum.
Applying a thick layer of mulch – up to 4 inches (10 cm.) – over the root area of the tree protects the roots from winter damage. Watering well before winter freeze is also a good way to help the tree survive the cold. That kind of winter protection for Japanese maples will work for any plant in the cold season.
Red maple is one of the first trees to show off red flowers in the spring and displays a most magnificent scarlet fall color. Red maple is a fast grower without the bad habits of fast growers. It quickly makes shade without the compromise of becoming brittle and messy.
