Flowering Crab Apple Trees

  • From £49.99 (VAT Free)

Malus x robusta 'Red Sentinel' is a small ornamental tree that provides a vibrant display of cherry sized deep red fruit. In spring, white blushed flowers emerge from pale pink buds to produce a cloud of fragrance. Mid-green leaves turn bronzed yellow in the autumn before falling and leaving behind the glossy, postbox-red fruits adorning the branches that often last right through winter.

The profuse fruiting on Malus 'Red Sentinel' naturally controls the size of the tree, that forms a rounded head and will grow to an estimated height and spread of 5 x 4 metres in 20 years. Suited for culinary use, these crab apples are perfect for jellies but are also commonly used in Christmas decorations. This particular Flowering Crab Apple tree is tolerant of pollution, suited to most soil types and has been awarded the RHS Award of Garden Merit.

This variety has large crab apples ideal for culinary use, so is sold with zero VAT.

Planting Advice for Flowering Crab Apple trees

When planting flowering crab apple trees, such as Malus Red Sentinel, it is important to prepare the planting area well. Pot grown Malus trees can be planted at any time of the year. Bare root crab apple trees need to be planted between November and March. If you are not planting your bare root crab apple tree straight away, it is best to ‘heel in’ your tree. Dig a hole in an unused area of soil and pop the roots of the tree in, gently firming around. If you’re planting within a couple of days, you can untie the bag around the roots, water, re-tie and then store in a frost free garage or shed.

Whether planting a pot grown or bare root crab apple tree, you will need to carry out the following to prepare your planting site. Firstly, remove all weeds and grass within a metre of your desired planting hole then dig a hole as deep as your root mass and approximately 2-3x as wide. We recommend digging a square hole as this encourages the roots to grow straight as opposed to around inside the hole. To help your tree establish more effectively, we advise applying root grow (sprinkle in the hole for pot grown trees or prepare and apply the gel mixture for bare root trees), especially if you have poor soil. Gently loosen the roots and place into the planting hole.

Using 50% of the original soil and 50% compost, fill in the hole and firm around gently. Make sure not to bank the soil up around the collar of the tree as this can cause problems. To see how to use a tree stake and tie, watch our informational how to videos.

Aftercare Advice for Malus Robusta Red Sentinel trees

If you’re planting in dry weather, water well and regularly for the first few months. The same goes for spring and summer planting. Make sure to keep an eye on your young tree and increase watering if there are extended periods of warm or dry weather. If you’re planting in autumn, you may only need to water your tree a little. We also stock a range of irrigation kits, suitable for a variety of planting schemes.

Once planted, it is important to keep the area free of competing weeds and grass for the first couple of growing seasons. Using a glyphosate based weed killer or installing mulch matting and bark chips will aid in this. Do not simply mow the grass around the area as this will only encourage it to grow more vigorously. If you know your area is prone to rabbits, we would advise using a rabbit guard.

Pruning Advice for Malus Robusta Red Sentinel trees

Flowering Crab Apple trees can be pruned in winter. They do not require hard pruning and you should not trim the tips of crab apple branches. Simply remove any dead or damaged branches and shoots at the base of the tree i.e. suckers and water sprouts which redirect energy resources from the main stem but do not produce strong branches.

The product table gives the sizes and forms offered for this variety, along with photos you can enlarge (these are only a guideline as all plants are unique so vary slightly). Below are definitions of various forms, which refer to the shape of the tree defined by the pruning it has received. For more information, please contact us.

Single Stem / Pruned and shaped: Classic shaped tree with a single stem that has had pruning to help create a beautiful, natural shape.

Top grafted: A height noted next to this form refers to the length of clear stem, which will not grow taller. Only the head of branches will develop. Top grafted trees do not require complicated pruning and are ideal for small spaces.

Multi Stem: A multi stem tree is has two or more stems arising from or near ground level, growing from one root system. Take care to buy a true multi-stem like all ours and not those that are 3 saplings in a pot to cheaply imitate them.

Feathered: A feathered tree has branches from the bottom of the trunk all the way up. These branches can be removed if a clear stem is required.

Bush: A plant with many stems low down, rather than one clear stem.

Climber: A plant that is a natural climber and will be delivered usually running up a bamboo cane, ready to position in the garden.

Standard Tree: A more mature tree with an upright clear stem of approximately 1.8m-2.0m (measured from the soil to the lowest branch), which supports a branched crown. Standards are available in different forms relating to their girth size (circumference of the stem measured 1m above soil level), not height.

Standard  either 6-10cm or 8-10cm girth, approximately 2.5-3.0m in height
Premium Standard  10-12cm girth, approximately 3.0-3.5m in height
Heavy Standard  12-14cm girth, approximately 3.5-4.5m in height
