Last year some florists ran out of stock towards the end of Valentines Day as flooded roads forced flower-laden trucks to turn back.

Flora Lea Florist and Gifts owner Betty Spanner said she ordered a month ahead of time to ensure she has plenty of supply for Valentines Day.

"To make sure I get everything my customers want, I order at least a months ahead," Mrs Spanner said.

"I also fly my supplies in instead of using trucks because they take too long and sometimes my supplies freeze."

Flowers by Ally owner Ally Harris said she too disagrees with using trucks to order supplies for her florist.

"Flying my flowers in allows same day delivery if you order in the morning, so you get fresh flowers and deliver quality product to your customers," Mrs Harris said.

She said this year's Valentines Day was already bringing in plenty of orders to her store.

"This is my first Valentines Day, but I am sorted with plenty of couriers and two more staff members to help out with arrangements and orders for the busy day."

Isa Florist owner Sue Ryan said they use both truck and fly-in services to obtain an assortment of stock for Valentines Day.

"We get most of our flowers from a couple of suppliers so we are well covered if trucks can't get through to the city in time for the big day and it also means we have a great assortment of flowers and gifts," Mrs Ryan said.

"This year we are expecting sales to be bigger and better, so we are more organised and we have great ideas and plans this year for our customers."
