70 days. If full-sized watermelons are too much to handle or your garden won’t accommodate sprawling plants, you’re in luck! Mini Love’s personal-size fruit and compact plants can squeeze into even the tightest space. The 7-9 pound watermelons have deep red, sweet, juicy flesh with a minimum of seeds. Glossy skinned, these watermelons have a remarkably thin rind yet are very resistant to splitting. The compact plants stay within a 36 inch space and will yield up to an unbelievable 6 fruit each!
