Fertilion

The Fertilion is the first plant obtained in Red Sands. Fertilions fertilise martian soil by blowing seeds onto red tiles which in turn grow into grass.

Suburban Almanac Entry
Most plants hate waiting for grass to grow. It’s slow, it’s boring, and the plants usually get impatient. They want to be planted on that spot now, not later! Fertilion, on the other hand, is fine with it. Waiting for grass to grow is part of his job description. It can take a while, but at least if he watches it, he can see if there’s room for improvement. After all, how else do you speed up grass growth? Sometimes, you just gotta march through the tedium, you know.

Plant Food
Grows grass tiles in a horizontal and vertical cross pattern centred on the Fertilion.

Implementation
Fertilion will blow seeds in the same way as Dandelion, forward and randomly across three rows. The plant will not blow seeds if all tiles in its range are grass tiles. Its attack cooldown is the half the duration of a sluggish recharge. Blovers and Hurrikales will also affect Fertilion in a similar way as Dandelion, but will instead blow three seeds. It will take two times its cooldown to regenerate its seeds, giving the player a two extra grass tiles overall.

Strategies
Fertilions MUST be planted on grass. Note that Fertilions can only blow seeds forward, unless given plant food. Hence, it is crucial that the back row of grass tiles and any subsequent columns are not chewed off, or else you will severely limit your planting space or even cause a potential game over scenario. It is very unlikely for this to happen, especially given it's the final row of plants, but it is a possibility.

At the beginning of a level, place at least two Fertilions in the back row to cover the entire lawn. This should give you fairly steady grass growth. If you use more Fertilions, it may be more difficult to defend against initial zombies, but it will allow setting up your defences earlier.

TBC once I have announced a particular herbaceous zombie... whatever that could be ;)
