Well that is a good sign that it is plump and green...it takes a couple weeks sometimes for it to form a good tap root. It's a lost cause when the seed turns black and molds.

i planted a mango 6 days ago and i heard that you have to plant it on a certain side... is that true? if it is what do i do if i planted it on the wrong side?

Hi teenager!

I planted 3 within the last couple of weeks. All with the heavier side down and the other end sticking up over the soil line so that it's only have buried (like avocados). Put all in full, hot sun...didn't move for the hurricane bands we got this past week or anything. All are growing and about 4-6" tall.

My mango seed from my home grown fruit germinated over the weekend! Now another of my fruit trees is a mama...I feel like such a dork lol!
