Rose Gardens

Okay, I've managed to get Expert on all of the first three levels. Now I'm starting level 1 on the Rose Gardens.
Does anyone have any advise on how to get the Expert on this one?

I would recommend planting as many flowers as possible. I got a great tip a few weeks ago to plant plant plant even if it is not the expensive ones, but the combos make up for it :c) Good luck!

That's great! I'm up to level 5-8 now. Thanks!

Except, now, I'm having more problems: I can't reach Expert on 5-8.

More help, please.

I'm new at the game. So, is the first primary strategy to keep using your mana (especially at first) to buy as many plants as possible and then plant them quickly? And which is the better strategy.... to place the plants in their corresponding color fairy rings, or is it more important to make the adjoining color chains as large as possible?

Any help or tips would be very appreciated.

ive played the free online game and this is what ive leant, usuall the dust is together so plant them on the dust and youve got a group , but if theres only one dust plant one ine it and plant oters around it.
