When does a blackthorn flower?

Mr N sent us a question: I bought some blackthorn specimens from yourselves in 2009 to create a
defensive planting.   Although the plants are growing well and seem
healthy, they have still never flowered.  Someone suggested that they
might not be female specimens.  Is this suggestion a load of rubbish
or is this species one of these plants with male and female attributes?

And the answer is:
The blackthorn flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects. They should flower when around 5-6yrs old.

Native Mixed Hedge pack

We're adding our customer questions to our blog to help answer yours!

"Hi there,
I am looking for 8 metres of new hedging for my front garden.
I am keen to have the native mixed hedge in the Mixed Hedge Pack but not sure if the 45 plants is too many for the length of hedge required?
Would you be able to advise on this and confirm how many plants I should need for 8metres?"

We recommend 6 plants per metre for a thicker hedge, planted in a zig zag or 4 plants per metre for a single row.  This works out a total of 48 plants if you were to plant the thicker hedge. We would also recommend that you purchase spiral guards for protection against rabbits etc.

Cotoneaster lacteus, after fruiting
Hawthorn, Crataegus monogyna, in winter remove selected shoots
Hazel, Corylus avellana, after the catkins have flowered
Holly, Ilex aquifolium, in late summer

Trimming with shears: To keep the top of the hedge level and flat, keep the blades of the shears flat and parallel to the line of the hedge.

Cutting with electrical hedgetrimmers: Use a wide, sweeping movement whilst keeping the blade parallel to the hedge.

Choosing plants for a hedge:
When selecting your plants, consider their eventual height and spread. Think about the climatic zone you are in for hardiness and if your local environment is suitable. It is worth having a good look around your local area to see which species are growing well. Consider the fully grown plants' density. If it is to be a formal hedge, you need a good dense plant like Yew or Box. For an informal hedge, you should select flowering plants and consider a selection of species to create a mixed hedge.
