Plum Trees

Plum Trees Plums Gaes Greengage Gage

Plum trees are regularly grown in gardens in the UK and their fruit is traditionally made into jam and eaten on its own. They can also be made into a fruity wine or dried and eaten as prunes.

The trees flower in early spring and cover the tree in blossom. Normally around half of the flowers will turn into fruit but this can depend on the weather. If there is a late frost, the tree could lose all of its flowers, and the fruit set will be lower than normal – you may even not get any fruit at all if the frost is severe enough. If there has been very little rain, the fruit crop will suffer, and you will also get less fruit if it has been too wet.

The Greengage is a close relative of the plum. It was developed in France and is small and oval-shaped. Unlike plums, they are green or yellow, and are the tastiest of eating plums.

Varieties of greengage include:

  • Bryanston
  • Cambridge Gage
  • Golden Transparent
  • Laxton's Gage
  • Laxton's Supreme
Growing Plum Trees
Plum and gage trees are easily grown in the UK and need very little maintenance.

Choosing Your Plum Tree
If you want to grow your own plums, you will need to consider a few factors before buying your tree. How big do you want it to grow? Do you want cooking plums or eating plums? How many plum trees will you need in order to produce fruit?

How Big Will it Grow?
You can buy plum trees to suit nearly every type of garden. Fan trained trees only grow to a height of around 2m, and a width of 3m. They are ideally grown against a south or west-facing wall. You can also buy free-standing fruit trees, which grow to an eventual height of around 2.5m, and are ideal for smaller gardens, where a fan-trained tree wouldn’t be suitable.

Bush-trained plum trees are also an option. They are also freestanding, and grow to up to 4m in height. They are ideal for larger gardens. Growers looking for a really large tree might want to consider growing either a half standard tree (they grow to 6m), or standard plum trees (8m). You will need to use a ladder to reach the fruits from these trees, however.

Cooking or Eating?
The following guide will help you learn more about varieties of plum tree and the best one for your needs.
  • Blue Tit – produces a large crop of delicious blue plums
  • Czar - eating plum with yellow-green flesh
  • Old English Greengage – best tasting of all gages, this tree produces a small crop of very juicy fruit
Some plum tress are self-fertile, which means you will only need to buy one, but many require another tree growing nearby for pollination to occur. If you do choose a tree that requires another variety to cross-fertilise with, choose one that flowers at the same time.

Plum trees are varied and they are a fantastic choice of tree to grow in the garden. With the right conditions, they will produce masses of fruit every year that can be used for a variety of culinary treats.

My Victoria plum tree was overflowing with plums last year but hardly any this year. Is that normal?

I have a friend with a plum tree that has a heavy crop of ripe fruit throughout June. This is obviously very early. It’s a dark blue plum, very sweet. Any idea of the variety.

We have a Victoria Plum which is 15 to 20 years old, 2 years ago we had a brilliant crop, last year we had just a few and this year we have a lot of very small ones which seem to be changing colour but not ripening and then dropping off the tree. Has the tree come to the end of it's lifespan or is it just reacting to the changing climate?

We have a plum tree but I do not know what variety as it was there when we moved in 15 years go (SW Wales). This year, the plums are a nice size and some have started to turn a purplish colour as they always do. However, some have a clear sticky substance on the outside of the plums. The green ones do not have this, only the ones turning purple. The tree is very tall, estimated 17-18 feet high. I intend pruning it down, by 1/3 required each year, which is what I believe to be correct way. Any idea about the sticky substance please?

For the last few years my victory plum tree .goes on a growingSpirit in the summer . It grows about 1.5 m in the summer and does not produce any fruit . I have had very little fruit from this tree In the past . Why does the tree grow in summer when it should be producing fruit , do I need to shock the root system and cut around the base of the tree about a metre away from the trunk . Any advice on resolving this problem would be very helpful because the fruit are very delicious but sparse ..

My plum tree is smothered in fruit this year but the leaves are curled and we’re very brown in places. Someone told me all fruit trees are suffering this year because of the extremely hot Easter followed by cold weather. Should I just leave well alone ; can send photo if you want

Hi, A large number of the leaves on my plum tree have not developed properly. They are tiny and the leaves are bumpy. What has caused this? The tree has been growing successfully in a large tub.

I have a patio plum tree and lots of plums but they have gone flat and shrivelled what can I do? Can I send picture?

Our Victoria plum tree has had lovely blossom and lots of plums but some of the tree hasn't many leaves,what could be the cause of this.

I have a young plum tree, last year we had a few plums. But this year there are quite a few but they are mishaped,flat and yellow Why has this happened, any advice would be grateful

I have two mature plum trees in garden. each year the yield of fruit is pretty good but every year as the flowers start to come through, the local pigeon population take turns to sit in the tree and peck at the flowers. This year I decided to try putting a net, mesh sized approx. 1cm over the trees as the flowers started to appear. This has certainly stopped the pigeons but not the leave seem constricted. should i remove the net again or will the fruit come along as usual ? Thanks in advance for your thoughts .

Hi, I planted a Plumtree (Czar) last September and we are now in mid April and it is still not showing any signs of leaves. Is it dead? Or should I wait longer?
Beate - 19-Apr-19 @ 4:58 PM

I bought a plum tree today, Opal, and it has thorns. Is this usual for an Opal plum tree?

I bought a mature plum tree from a nursery a year ago. I say "mature" because its trunk is approx. 8 inches in diameter. It produced one plum this summer and then started exuding brown globules of a sticky, glue-like substance. I have had conflicting opinions ranging from "this is normal" to "your tree is dying" from various sources. I'm happy to send you a photograph if this will help. Can you enlighten me?

@Keirren -Do a small scratch test.You can scratch the bark of the trunk of the tree, just a small amount. If you scratch away the bark and the wood beneath is not green, then your tree is on its way out or dead. Trees in pots need a lot of water - it could be that you have starved it if you have only given water occasionally. It would explain the sudden loss of leaves.

I bought a plum tree from the local garden centre about 2 weeks ago it's about a 9-12 months old and we have kept it in the pot as we were going to plant it in the garden on Saturday on my daughter first birthday over the past few days however the leaves have all turned yellow/brown and are falling off I'm sure this is too early for the autumn fall so I'm worried that it's dying... It's in a well sunlit area shielded from the wind by a hedge that perimeters the garden and I've been giving It water occasionally

I have a plum tree I’ve had 4 many years n it hasn’t flowered or produced fruit last year I had very small green fruit but wasn’t big enough n it’s never ever flowered Opposite I have a discovery apple tree which is doing very well The plum tree nothing is happening to it it looks very healthy though I don’t really have any idea b cause I’m not a gardener I bought the tree as it blossomed wen my cat died n it stands in her honour My apple tree is because of another cat I thought as the apple tree was doing so well that I’d try a plum tree but I’ve had the tree a long time no blossom or fruit

@Cobra - If from the outside the plum looks OK (or there may be a small brown mark on the skin), then it could be the plum sawfly.

I have a plum tree in the garden 3 years old and this year when just picking a few off which were ripe they have brown specs inside, I picked some off the not so ripe and inside they are the same, outside no problem They have been watered well during the drout,, can they still be eaten and what is causing this?
Cobra - 11-Aug-18 @ 2:56 PM
@Nico21 - The tree has only so much energy to use to produce fruit so thinning (removing some of the fruit) is essential to produce a good crop. But it's usually done earlier in the year and for the present year's crop.
AaronN - 10-Aug-18 @ 3:24 PM
My plum tree is covered with fruit for the first time.I have been advised to take off the not yet ripe fruit now to obtain a better yield next year, is this right?
Nico21 - 9-Aug-18 @ 8:37 AM
@Jan - it could also be plum sawfly. If there is a brown dot on the plum itself that it due to the pest burrowing inside. You'd have to research how to control it. It's not easy :(
Sal1978 - 7-Aug-18 @ 2:50 PM
@Jan-I'm afraid to say your plum has been invaded by the plum moth and the brown flecks are the excrement of the maggot that may still be resident. (One reason not to preserve plums whole as you may be preserving more than you bargained for). If you aren't put off eating them completely you can cut away the damaged/dirty areas and eat the remainder but it is one hell of a faff!
Devman - 7-Aug-18 @ 2:04 PM
Just picked some Victoria plums from the garden but when cut open they have brown specs inside.What is this?Can they still be eaten?Thanks

Hi, we have a Victoria Plum tree in the garden, which has these last 6 or 7 years produced loads of blossom but the fruit is very small and purple. It still tastes of plum but they are so small. We live 1/4 mile from Buncefield Oil Depot which blew up December 2005 and before this and for a few years after, apart from 2006, the tree was heaving with fruit. I was giving them away. I do believe that the explosion affected the tree as the following summer the fruit were purple black and small, much as they are now. Does anyone have any ideas please on why it won't produce lovely golden and red plums anymore? Thank you!
Dawny - 24-Jul-18 @ 5:56 PM
@Woody - it might be about the variations in the water supply available at the roots. Hard to say really. the most important thing is not to waterlog the tree, but to keep water more constant if you can (if the tree is in a pot).
