Here is a picture of one of my giant tomatoes on it’s way to stardom. (I hope!)
baby giant tomato
Notice this tomato looks deformed and gnarly. It has 4 little tomatoes that have fused together-kinda like Siamese twins only this one is quadruplets! Most giant tomatoes are a result of a megablossom where 2 or more blossoms fuse together. Many megablossoms do not pollinate fully and so they have a higher self abort rate. So far this one is doing well. I have a few other megablossoms right now but not many. Some varieties produce more megablossoms and hence more giant tomatoes. Two varieties that have the potential of producing giant tomatoes are Delicious and Big Zac. There are other varieties that can produce giant tomatoes too. This one in the picture comes from a Nick Harp tomato seed. His plant grew a 7 lb+ tomato last year and he gave me a few seeds. I call his plants the ‘Harpies”! I have 5 growing right now. Hope this one becomes a monster! Since I’m an organic grower I’ve been feeding it fish and seaweed fertilizer from the Neptune brand.

GIANT TOMATOES-I got my first 2 megablossoms off my Big Zac tomato plants and they are not even in the ground yet. All giant tomato growers are looking for megablossoms. Some varieties tend to produce more than others. Since megablossoms usually come earlier on a plant I will leave these on as I don’t know if I will get more off each plant. A megablossom is at least 2 or more blossoms that fuse together to make one big tomato. That is why giant tomatoes are so knarley and bumpy. It is kind of like twins, triplets or quadruplets that are all conjoined together. Recognizing these megablossoms is the key to growing giant tomatoes. It doesn’t happen all the time so it is exciting when we get some megablossoms and the potential for a BIG TOMATO. Since they are made up of many blossoms, oftentimes they abort if they don’t pollinate well. Most tomatoes are self-pollinating so you don’t have to worry about pollinating them unless you get a megablossom. That is when we should hand pollinate them although I didn’t on these. Using a small soft paintbrush, you can take some pollen off of the stamen part of one blossom and paint it onto the megablossom pistils. Kind of sounds like Luther Burbank doesn’t it?
The top picture has two blossoms-the one on the left is a normal single tomato blossom and the one on the right is a megablossom made up of two flowers. Notice how big it is.
megablossom with three blossoms fused
This second picture has even more blossoms fusing together. Looks like maybe three blossoms. Starting to look knarley! I’ll see if it aborts or starts to grow into a giant tomato on it’s own as I didn’t hand pollinate them. I will pick off all the normal blossom off of each plant. I might grow 2-4 tomatoes from megablossoms off of one plant. You don’t let all of the normal tomatoes grow so all the energy goes into these potential giant tomatoes. Obviously I am growing these for size and I have other varieties where I let every blossom become a tomato to grow for food.
