Ron Wallace's Whoppers Giant Pumpkin Seeds (5 Seeds per Package)

First year with these seeds. Germination rates weren’t great but still grew a 600 and 700 pound pumpkin. This picture is of the 700 pound.

All 5 sprouted. I bought these as backups for some more expensive seeds. If everything goes as planned, I won’t be growing these plants to maturity. If my expensive plants don’t make it and I do end up growing these to maturity, I’ll try to update this review.

These seeds are a waste of money. I planted them 3 times and each time they did absolutely nothing. The first attempt was in pots indoors. I don’t have a greenhouse but I followed the instructions on the package and used a high quality potting soil. They did not sprout and rotted in the pot. A few weeks later I planted another set outside in the garden in fertile soil mixed with some potting soil. We then had about 2 weeks of 50 degree temps with a lot of rain. They again rotted in the ground which was expected because of the unfavorable conditions. My last attempt a few weeks later (end of May) also ended the same way. Not a single seed even germinated. For as much money as they charge for these seeds I expected much better results. This was a disappointment to say the least. I would not waste your money on this product.

What I did:1) Collect compost, or buy some seedling soil from Walmart, or go into the woods and dig up some free, quality soil. I used compost. I used to grow weed indoors, and in my experience, you don't want a ton of nutrients in the beginning. Synthetic nutes like Miracle Grow will burn your babies.2) Go buy some peat pots, sandwich bags, and some bottled water or jugs of spring water. Again, I learned from growing weed that ph is important. The water from your tap is probably in the 8-8.7 range and Google told me pumpkins like 5.5-7.5. Bottled, spring, and distilled water are all around 7 ph in my experience. For these pumpkins, I used Kroger bottled water. Don't underestimate ph! It's ridiculously important and easy to get right.3) Fill the peat pots with soil. Leave about a half inch or inch at the top, so water doesn't just wick off the soil and down the sides of your peat pot. Dry soil does not absorb water well, so it needs to pool a little at first and seep into the soil. Go ahead and soak your soil with your store bought water.4) I dragged a razor in a criss cross pattern on the outside of the seeds. I applied no pressure. I just scratched. Then I pushed the seeds an inch into the soil with the point down. Scratching the seeds may do nothing, so if you want to be lazy, skip that step.5) Cover your peat pots with sandwich bags to keep the humidity and temperature high. You don't want it airtight. Now you have 6 little greenhouses. Put them in the sun, and make sure you water once a day. Small pots dry out extremely fast. You want high humidity and damp soil, but make sure it gets super wet, and dries out, gets super wet, and dries out, etc. You absolutely don't want standing water or your roots will rot with a quickness. Peat pots should prevent that from happening unless you have them sitting in a dish that holds the water that drains out.Like I said, that is how I got 4/6 to germinate and sprout, which is mediocre but not disappointing haha.

I've been growing pumpkins and other things for a long time but I'm no expert. Unfortunately none of these seeds were able to germinate. I'm not sure we can hold anybody accountable for the viability of seeds. It's kind of out of the seller's hands I believe. But I had to report the facts. I even went to his website earlier in the year and bought some giant pumpkin seeds, and those also did not germinate. My dream of having a giant pumpkin has not happened. I think I will try again next year.

This was his first ever attempt at growing a giant pumpkin and the seed did not disappoint. Great for a beginner. This pumpkin won 3 ribbons at the fair and was about 590 pounds. It broke the scale at weighin and they didn’t get an accurate measurement. We grew this in zone 6b in clay loam. No doubt that it would have been double in size if we amended the soil.

I planted 5 seeds where I have been planting the Dills Atlantic Variety for the last 10 years. I put the seeds into the ground the same time I always do. The Saturday of Memorial Day weekend. Only one seed germinated and as of the date of this review I haven’t even got a female flowers and the plant is barely 10’ long with only two runners starting. Usually by this time I have several large pumpkins on the vine between a couple of plants.

These seeds are the best this is my second time growing this particular strain. Several years ago I harvested three 160lbs+ pumpkins 10 days before Halloween in my back yard. It's a good idea to hand pollinate with a Q-tip to ensure a fruit sets on your vine. Definitely bury your vines with high quality soil. Hope someone else discovers how amazing growing giants can be even in a back yard!!
