Blue Tit has round medium sized dark blue plums with yellow flesh They are quite juicy with good flavour for eating and cooking It is a reliable cropper and a good garden variety Plums are sent from November until March as bare rooted one year old trees All varieties are self fertile unless stated They need a sheltered position protected from frost Plum trees are quite hardy but they flower early in the year so if you loose the flower to frost there will not be any fruit The soil needs to be rich and moisture retentive but not waterlogged A sunny position will help the fruit to ripen and become sweet Plums do not store so pick and eat or destone and freeze Many varieties are dual purpose so as well as being delicious to just eat they can be cooked to make pies crumbles jams and chutney Prune plums in the summer after cropping unlike most other top fruit which is pruned in the winter
