Forum:Miracle Fertilizer question? please clear its description

http://yugioh.wikia.com/wiki/Miracle_Fertilizer

Once per turn, you can select 1 Plant-Type monster from your Graveyard and Special Summon it. You cannot Normal Summon or Set the turn you Special Summon a monster with this effect. If a monster Special Summoned by this effect is removed from the field, destroy this card.

My friend thinks this card can only be destroyed by another card's effect or if a monster summoned by this goes back to his hand, can you clear this up, it does mean if any monster special summoned by this is destroyed it is destroyed too or leaves the field for whatever reason the card is destroyed correct? thanks
