|Can watermelons and pumpkins be planted next to each other? I understand I would not want to chance saving the seeds to plant again next year.
|There is no problem planting watermelon and pumpkins next to each other. They will not cross-pollinate and you can save the seed if you wish. However, if you plant hybrid seeds, it is not recommended that you save the seed, as they do not come back ?true to type? of the parent plant. Seeds from hybrid vegetables usually produce offspring inferior to the parent. Only ?open pollinated? varieties are recommended for seed saving.
