首先要講清楚, 野草係weed, 而草係grass
個原因就係其實係有種子o係山坡既泥土裡面, 因為草係用風去傳播種子,而且可以留o係泥土裡面等到合適既時候生出黎, 所以這個唔係問題~
唔係冇, 只係少d養份o者, 但唔好忘記, 草係地球上其中一種生命力最強既生物, 佢可以o係熱帶雨林,沙漠, 寒冷既高原上生長都冇問題,山坡係小兒科啦, 而wikipedia對weed有咁既description:
....the weedy nature of these species often gives them an advantage over more desirable crop species because they often grow quickly and reproduce quickly, have seeds that persist in the soil seed bank for many years, or have short lifespans with multiple generations in the same growing season. Perennial weeds often have underground stems that spread out under the soil surface or, like ground ivy (Glechoma hederacea), have creeping stems that root and spread out over the ground. A number of weedy species have developed allelopathy, chemical means to prevent the germination or growth of neighboring plants.
3. 佢好快就可以繁殖下一代, 可以出現同一個時間幾代同堂
