General advice for a complete novice

Hi

Just wanted some advice from the experts on the below please.

We have bought a patio rose tree, some geraniums, oriental lillies, and a patio rose plant.

We are wanting this to thrive, look beautiful and return each year. I know i have to feed them and prune the roses but dont know when or how to do this.

They are planted in John Innes number 3 as recommended by the garden centre.

Please can anyone advice me on how to look after the above e.g when to feed and prune etc??

Thanks

 

Feed with high potash liquid feed two weeks after planting, (gives them time to settle in.) dead head flowers regularly, prune in early spring ie mid feb to outward facing buds. Dont take any notice of garden centres JI No3 is expensive, any compost will do.

Personally I would fill half with well rotted manure and top up with compost

 

I've never used JI No3, is it really expensive?

 

Around 25L for a fiver., as against Wickes 4 75L bags of Nutrient rich peat based stuff for 13GBP!

Cheers.

 

Already used JI number 3 now so thats by the by.

Anything else i need to know about the questions below?
