If I happen to grow the vegetables for this year it will be grown up to the seed production phase so that I can generate and preserve some seeds for next year harvest to avert this kind of challenge. Preserving the seeds myself will keep them in good condition and for next year planting I will have no issues as to whether my seeds will germinate or not.
Exactly what I wanted to advice you. Most people selling these seeds do not know how to preserve this so that they would be useful for the next farming production. So, the best thing is to grow the veggies to the seeds level, since you know how to preserve them. Sorry for the inconveniences it might have caused.
Thank you so much.
You are welcome
