Brassicas include: broccoli, cauliflower and cabbage 

Dig the soil over and add organic material such as garden compost in the winter.  When early spring arrives dig the patch again and sieve the soil so that it has a fine tithe to it.  Add lime to the surface of the soil and fork it in.  However, there is a remote possibility that your soil is already alkaline - in that case adding lime isn't necessary.

Growing seeds in seed trays and putting those trays in sunny warm conditions helps them develop quickly, so I highly recommend using a greenhouse or putting seed trays on the window ledge, on the sunny side, of a house.

Skimmia are ideal plants for low maintenance gardens because they are drought resistant so they allow you to go on holiday throughout the summer without having to water the garden.  In addition they do not require pruning, which can be a time consuming endeavour.

These plants are medium-sized deciduous trees.

A good set of plants for a sunny border is shown below.  It is sensible to plant one of each plant that we mention unless we state otherwise below.  

Hebe

Buddleja x weyeriana

Lavandula stoechas (plant about 3)

Syringa microphylla 'Superba' 

Rosemarinus officianalis 

Sedum spectabile (plant about 6) 

Euphorbia myrsinites (plant about 3)

Salvia x sylvestris 'Blauhugel' (plant about 4)

Geranium pratense

When you plant ensure you look at the expected height of the plants you plant so that you can ensure the taller plants are towards the back of your border.

Having a hedge planted is an ideal way to create a border around your garden.  Hedges subdue the wind effectively (far better than fences and other solid features) thereby making your Yorkshire garden less weather beaten.  Plants that don't fair well in exposed conditions will benefit from the protection of a hedge.  

We have experience of planting mixed native hedges.  Seeing them grow into large effective hedges is rewarding.  

Quite a lot of hard physical work is needed to plant a hedge so you may want to employ a gardener to do it.

Plugs can be planted directly into areas of turf in order to establish a wildflower meadow. 

A crop such as oil-seed rape can be grown on the soil and harvested.  The crop takes nutrients out of the soil and removing the crop at flowering time ensures the nutrients do not return to the soil.  Soil that has low fertility is typically needed for a wildflower meadow

We can control weeds and vigorous grasses by introducing plants that are semi-parasitic.

Ragwort is a generally seen as a weed.  It is toxic to horses.  To get it out dig out the roots; some of these weeds have very long root structures so dig deep down as if you are getting rid of a dandelion.  

Ragwort does provide a home for various caterpillars though so you might want to keep it.

Foxgloves contain digitalis which is poisonous in quite small amounts so you may want us to dig it up and get rid of your foxgloves.  Foxgloves are excellent for bees and quite attractive to some so we recommend keeping some for this.

Just about any vegetable can be grown in containers.  Raised beds are ideal for vegetables (we can build raised beds for you).  Otherwise it would be a good idea to buy a contained to at the least the size of 18 inches by 18 inches.

Good vegetables to grow in containers include: beans, carrots and beetroots.

Herbs are ideal for containers.  Try planting:

sage

thyme

rosemary

oregano

If you grow mint ensure it is in a separate container otherwise it will overwhelm the other herbs.  

Common Hazels are small deciduous shrubs.

These plants reach a height of 4 to 8 metres. 

Common Hazel has a branched spreading habit. 

The flowers are yellow in colour.  These give way to edible nuts. 

They have rounded leaves that turn yellow in the autumn.  They have yellow, male catkins in early spring. 

They are indigenous to the UK, hence they are often used in wildlife gardens. 

This plant enjoys full sun or partial shade.  They prefer well-drained soil and chalky soil.
