While I'm not familiar with this NPC, there are a few NPCs that say they will give you something if you keep bringing them a specific junk item however they are broken and you can't interact with them after the initial conversation. Unfortunately, unless someone has made a mod for this, there is no fix.

Are you trying to sell her the fertilizer junk item, or the bag of fertilizer item. She only buys the bags (the ones that can be broken down into 1 acid and 4 fertilizer each), not the individual units. There are also known bugs (from the wiki):

When trying to sell fertilizer to Dr. Penske, she may just give generic dialogue instead. [verified]

Reverse-pickpocketing one bag of fertilizer onto Dr. Penske will resolve this, since the code erroneously checks her inventory to trigger the dialogue, not the player character's. Alternatively, the console command 2a826.additem 5a0d9 can be used to add a bag directly to her inventory without the risk of being caught pickpocketing.

The player character must sell the fertilizer to Dr. Penske before completing Hole in the Wall. Otherwise, even the above solution will not trigger the fertilizer dialogue.

Upon completion of the quest Hole in the Wall, she will no longer buy fertilizer from the player character. Instead, she acts as a generic character on a rotation of set dialogue. In most instances, her dialogue will proceed to offer quests for fertilizer but it does not actually start the quest nor make her accept fertilizer regardless when to talk to her.
