ALAN Tichmarsh is making a Runcorn mum’s dream come true tonight.

Mum-of-two Karan Waller, aged 37, was diagnosed with a low grade astrocyloma after collapsing at home in 2009.

Despite surgery, the growth returned and surgeons told her they can’t operate again.

She wants to thank her family for all their support as she battles a brain tumour.

In Love Your Garden on ITV at 8pm tonight, Alan’s team of landscapers and horticulturalists will transform her garden into a multi-functional space she can enjoy with her husband, Ian and their daughters, Harriet and Charley.
