MyI've been interested in plants appeared whenever since I was little.

You could also say, "My interest in plants began when I was little," but the version I wrote sounds more natural/idiomatic.

That is probably something that was passed down onto me from my grandparents.

EspeciallyIn particular, my grandmother used to spend a lot of time taking care of plants.

Same meaning, just sounds a bit more natural to me.

My grandfather was more interested in growing different types of plants, such as fruit trees or grapevines.

Because I spent a lot of time with them, I have developed thean interest in gardening.

For the cooking, I havI use oregano, thyme, sage, and chives for cooking.

I rearranged this to make it sound more natural.

Sometimes, I make them both from home-grown herbs, such as peppermint, sage, balm, and marigold; and. I also picked herbs— for tea: coltsfoot, meadowsweet, flowers of lime tree, and othermore.

I broke this up into two sentences because this one sentence, while grammatically correct, is rather long. I know what you mean when you say "picked herbs," but it sounds just a little off.

This year, I'm growing milk thistle for seeds that have strong regenerative effects on liver.

I shouldn't have sown it so densely,planted the seeds so close together because it made them to grow thin and have smaller flowers, which in turn caused them to be prone to bad weather.

Not sure I understand the end of the sentence ("which in turn caused them to be prone to bad weather"). Do you mean that they couldn't survive bad weather?

It all lay down the same way as wheat does due to windy and rainy weather, but that is not an issue—the real issue is thorns.

Again, not 100% sure what you mean here by "lay down" :(

Currently, itThis is the third season I have been growing chili peppers.

I have tried many varieties of both species: Capsicum Annum and Capsicum Chinense.

Varieties of Capsicum Annum areis the most common onespecies.

Saying that it's the most common species implies that you are also talking about varieties,

They have a distinctive fruity taste and a high content of capsaicin—substance responsible for sensation of burning, which is a substance that causes spicy, burning sensations.

Same meaning, but just a little more natural-sounding to me. "Spicy" is a good word to use here.

There is yet another plant that I have triedbeen trying to grow for many years.

I would change it to "I have been trying to grow" if you are still trying. If you've given up, then "I have tried to grow" is correct (because it means that you stopped).

It is called Lycium Barbarum and Lycium Chinense, . It's more commonly referred as Gto as a goji Bberry Pplant.

I think it's correct to capitalize the species names, but not the common name.

Better word choice; appeared is ok, but sounds a bit funny.
