Start with Flowers
Flowers are more than just something pretty to look at; they're also a nuisance! Flowers can get in the way of some great matches, and you'll have to work around them until you've eliminated the ones that are positioned most inconveniently. Instead of fighting the flowers the entire round and losing points along the way, start by taking out those least convenient of plants. Your improved score once you have done so will be reward enough for the trouble.
