MacGibbon & Ross record that flower gardens stood to the side of the property within a walled garden.
In 1875 this garden was still under cultivation and in the orchard had stood the parent tree of the famous Auchans pear, the first of its kind in the county, brought in from France (or Norway) at an early date, said to be during the reign of Mary, Queen of Scots.
This tree had grown to a great height and was blown down in 1793.
In 2003 a sample of pears from Pluscarden Abbey near Elgin were sent for identification and were found to be the Black Aachen or Auchans pear.
Hogg's Fruit Manual also records them as growing in Cheshire.

The Auchans pear may have taken its name from the castle as the proper name, 'The Toadback Pear', had dropped out of usage.
It is a lumpy russet, showing great health and vigour and the fruit is described as being as "ugly as a toad".
Other varieties are Red Auchan and Winter Achan.
The flesh is described as tender, buttery, juicy, sugary, with a rich and aromatic flavour.
Auchans  are Scotch dessert pears of first-rate quality; ripe in November and December.
As stated, the tree is a very abundant and regular bearer, particularly when it has acquired age.
The Auchans pear spread all over Scotland as shown by the Pluscarden Abbey survival.

An artificial loch was situated within the policies, well stocked with fish.
The Old Bank is the name given to the tree-covered hillside to the west, bordering the old deer park.
An area known as Kemp Law is associated with the site of a vitrified fort and the Badger Brae that lies nearby.
The mid-19th century OS maps show a complex of out-buildings and a dwelling called Old Auchans, situated above the castle and with Parkthorn farm nearby; it had views of what is now the quarry.
The Old Auchans property is now ruinous; it may have been the dwelling of the estate factors before New Auchans House, now demolished, was built.
