VVA-1 - Rootstock for Plum trees.
Dwarf 2.5 metres when mature. The new dwarfing rootstock for Plum trees that has replaced Pixy.

St Julien A (SJA) - Rootstock for Plum trees.
Semi dwarfing, Approximate height 3.5-4 metres when mature.

Bare Root = Field grown trees that have been freshly lifted and supplied with no soil around the roots. Only available during the dormant period November-April.

10 Litre = Container grown and can be planted all year round. The size refers to the number of litres of compost that the container holds.
1 Year Maiden = A one year old tree and the size depends on the variety but in general they will be 100-125cm in height.
2 Year Bush = A two year old tree that has been pruned back in the first winter to form a bush shape. Generally trees will be 140-160cm in height with multiple side branches. This height guide is an end of summer height. 

Fan trained Plums - Trees grow to an eventual height of around 2 m (7 ft). Although the shortest of all the forms, they will grow to a width of around 3 m and are really only a practical proposition when grown against a wall or fence.


Pollination Made Simple 

Most suburban situations provide good pollen due to the close proximity of other gardens. It is not always necessary to have pollinators if the bees and other pollinating insects are generous with their visits. If you have no other Plum tree close by then select two varieties in the same group or the adjoining group ie group B and D will pollinate group C as will any others in group C. Some Plum varieties are self fertile. 



For most fruits choose a warm sheltered position avoiding wet or shaded spots, although soft fruit will tolerate some shade. Avoid north walls except when planting blackberries which will crop successfully, albeit, a little later in the season. Crops are likely to be sparse in frosty situations. If birds are troublesome a fruit cage can be erected.

Just received a one year maiden tree which is a lovely example. Bought it at a reduced price which makes it even better! Thanks again Blackmoor for helping to fill up my already overstocked garden!

14 Nov 18 | Mark and Imogen

Ordered in Feb 18 and planted out in the ground around the same time. The tree has grown well over the year with healthy new growth and a lovely shape. Took off all fruit early as it was newly planted but it looked to be a good crop - looking forward to next year,

Can't leave less than 4 or 5 stars or negative reviews here. Misleading feedback system violates Consumer Protection law by skewing buying decisions. This is illegal as well as cowardly.

Ordered a VVA root stock version last summer and have now received it. It looks in good condition and have planted it in a raised bed. Looking forward to getting some good fruit over many years providing I get the pruning right.

I come back to Blackmoors time and time again because the fruit stock is second to none; the customer service is excellent; the packaging is sturdy; despatch is swift ie a few days rather than weeks. Again, this Opal I have just received is one fine specimen. Thankyou so much everyone at Blackmoors. I love my tree!

Opal Plum Growing Tips.

Plums are the most popular of the stone fruit and they are also the easiest to grow. Many plum varieties are self fertile. There are two rootstocks to choose from; St Julien A which is semi vigorous and will reach a height of 3.5-4 metres when mature and VVA-1 which is dwarfing and will reach a height of 2.5 metres when mature. 

How to grow a Opal Plum tree in my garden - Our Care Guide for fruit trees will help you get the very best from your tree.

How to plant my Plum tree - Our How To Growing Tips section on our website has a video that will show you how.

When is the best time to plant a fruit tree - Container grown Plum trees can be planted at any time of the year. Bare Root Plum trees can only be planted between the months of November - April.

Planting distance for Plum trees - All fruit trees are grafted onto a rootstock. It is the rootstock that determines how big the Plum tree will grow into. There is a rootstock guide on the left hand side of all fruit tree product pages that explains this. As tall as the tree will grow into would be the planting distance. Example St Julien A will grow to 3-4 metres when mature. So a spacing of between 3-4 metres would be required.

Can I grow a Plum tree in a pot - All fruit trees will be happy growing in a large container. A pot around 50-60cm is ideal. There is more information on growing fruit trees in containers in our FAQ page.

How do I prune a Plum fruit tree - Our Care Guide explains the basic principles of fruit tree pruning.
