The King of Pentacles is the Prince of the Chariot of Earth and is aligned with the Earth signs of Taurus, Virgo and Capricorn. He represents expert manifestation of skills and resources. 
The King of Pentacles brings the harvest of creative endeavours, and is the realisation of rewards of effort, foresight and planning. He plods towards his substantial goals deliberately, seriously and without humour. As a person he is serious, sensual and astute.
He knows how to maximise his resources and looks after those he is closest to as an accomplished provider and custodian of money and property. When the King of Pentacles turns up in a reading it is time for you to get your financial affairs sorted out in your favour - you have the ability now to either attract those who will help you grow and secure your resources or you will find the information that will allow you to do this for yourself.
There is a focus on large established organisations, and these will be important to you now, and this will generally be in a helpful way. The realisation of long-held ambitions and goals, especially of a material nature, is likely now.
Patience is key, as is faith in a positive outcome, although care is also needed to protect what you have built up.
As a partner he is devoted, sensual and tactile. He is serious about his relationships and while it may take him some time to get around to declaring his feelings, when he does it is out of a sense of certainty and an eye on the long term. He makes an excellent partner, provider and leader and while he may be conventional and somewhat unexcitable on the surface, his heart is steady and passionate.
There is much to achieve for you now, and it does take commitment and the ability to work steadily towards your desires. Decide what you want for yourself and create a plan of action - then follow it steadily without getting sidetracked. The rewards for doing so are great. Image from "Labyrinth Tarot" © Luis Royo
