Malus x robusta 'Red Sentinel' Tree

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 Malus robusta Red Sentinel Trees

Our pot grown Red Sentinel Crab Apple trees can be planted at any time of the year. Start by removing weeds and grass within a metre of your desired planting hole. Dig a square hole as deep as your root mass and approximately 2-3x as wide. To help the tree establish more effectively, sprinkle root grow in the hole.

Remove the pot, gently loosen the roots and place in the planting hole. Mix 50% of the original soil with 50% compost, fill in the hole and firm around gently. Avoid banking the soil up around the collar of the tree. We recommend planting Red Sentinel Crab Apple trees with a stake and tie kit to anchor the roots - instructions are in the planting guide.

Aftercare Advice for Malus robusta Red Sentinel Trees

If you’re planting Red Sentinel in spring or summer, water well for the first few months. Increase watering if there are extended periods of hot or dry weather. If planting in autumn, you may only need to water a little. Our range of watering kits make it easier.

Once planted, keep the area free of competing weeds and grass for the first couple of growing seasons. If your area is prone to rabbits, use a rabbit guard. You can harvest the Crab Apples in early autumn or leave them for birds to enjoy.

Pruning Malus robusta Red Sentinel Trees

Red Sentinel 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.

Delivery Timescales

All trees are carefully packed by our experienced team and most are delivered within a week of placing the order (please allow up to 12 working days during busy periods). There's no need to be in to receive your order and you can request where it is left via the checkout.

There is a slightly longer timescale on pleached and mature trees (trees over 2.5m in height) because we group orders together for specialist delivery - we will contact these customers to notify them of the delivery date.

Trees on pre-order are still growing and an estimate of when they will be ready is given on the basket page. Orders will be despatched when all trees are ready.

Gift trees and those required by a specific date can be accommodated with pleasure, although we accept no legal responsibility for late deliveries.

Our nursery is a busy despatch centre, so please make an appointment to collect or view trees.  For collections, despatch charges will be refunded.

The product table at the bottom of the page gives the forms and sizes available for this variety. Please note, photos are a guideline as all plants are unique. Below are definitions of terms:

Supplied Size: Height measured from the top of the pot.

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.

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.

Multi Stem: A multi stem tree 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.

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

Clump: Several plants in one pot that can give the appearance of a multi stemmed and very bushy tree.

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 branches of the 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
