What are Sun Sugar Tomatoes?
Sun Sugar Tomatoes are a cherry-sized tomato. They are considered a yellow cherry tomato but they really ripen to a very nice orange color. They are a bit bigger than the traditional cherry tomatoes that I have grown in the past (Sweeties and sweet 100’s).
I have also found that they are overall more productive than many of the more traditional cherry tomatoes. They are also very early to mature. These are always the first tomato in our garden. They are also fairly hardy and make a good choice to plant extra early in a wall of water. We have grown them in walls of water for 5 years now and a mid-April planting will mean you have tomatoes by mid to late June!
How to plant?
In most areas tomatoes can not be started directly in the garden. They can be planted 2 ways
- Plant indoors in a seed starting container
- Plant by starts directly in the garden
If you choose to plant this variety of tomato by seed indoors you will need to start them 6-8 weeks before the last frost. To learn more about seed starting indoors go here to find out how to start these tomatoes by seed.
If planting starts then plant them directly in the garden 2 weeks after your last frost. They need to be planted deep. The recommendation is to plant so that ⅔ of the plant is below the ground. 24 to 36 inches apart. These plants grow big and so they need the space.
Pro Tip: A trick I learned from my in-laws to help your tomatoes to be sweeter is to throw a couple of banana peels and some organic compost in the hole that you dug to put your start in. Make sure you plant them deeper than the container they are in.
Growing Sun Sugar Tomatoes
Sun Sugar Tomatoes grow like most other tomatoes. They need good well-drained soil with plenty of organic matter. Sun Sugar Tomatoes benefit from an early dose of nitrogen fertilizer and a later dose of fertilizer that is higher in phosphorus (both organic fertilizers of course).
Sun Sugars are resistant to fusarium wilt and tomato mosaic virus. I have never had a disease problem with this variety either from seeds I have started myself or from nursery-bought stock. But it is still a really good idea to practice proper crop rotation and to avoid planting Sun Sugar Tomatoes in the same spot without at least 3 years in between plantings.
They need consistent water but be careful not to overwater or you will get all vine and no fruit. And make sure they get plenty of sun.
When to Harvest?
It is super simple to know when to harvest these cherry tomatoes and the easiest way I have found is to look at their color.
You will know they are ready to be picked if they have a deep orange color all around the fruit. There shouldn’t be any green on the tomato. Carefully twist the tomato without squeezing them otherwise they will split and it should come off easily.
I have read many places suggesting you can pick them green and they will ripen on the counter, however whenever I have tried this they don’t ripen well and they are not as sweet. So if you want the sweetest tomato you have ever tasted leave it on the vine until it has that bold deep orange color, you will be glad you waited.
Should I prune a Sun Sugar Tomato?
Yes!! There are so many advantages to pruning this cherry tomato and you will be glad you took the time to do it.
Here is why you should prune them;
- Tomatoes will grow bigger
- Improves the sweetness of your cherry tomatoes
- Higher production of tomatoes
- Reduces the risk of disease
This variety of tomatoes is indeterminant. This just basically means they continue to grow. They grow pretty large plants and will need some support. A tomato cage works well. But because they are indeterminant tomatoes they will benefit from pruning.
If Sun Sugar Tomatoes have one disadvantage it is this aggressive growth habit. I have found that they can get very aggressive by the end of the summer so be sure to give them a little space so they don’t overtake your other plants.
In fact, this year we are growing our Sun Sugar Tomato plant in a pot away from our other tomato plants to keep the Sun Sugars aggressive vines from affecting the growth of our other plants. Sucker pruning Sun Sugar tomatoes helps keep them under control. You can learn how to do “sucker pruning” from this article!
How does this variety taste?
This is no ordinary cherry tomato! They are bursting with sweet delicious tomato flavor. Sun Sugar Tomatoes are seriously the best-tasting cherry tomatoes I have ever eaten. Sun Sugars are like eating tomato-flavored candy!! They also have very thin skins so they are a pleasure to eat straight off the vine. They are soft and bursting with flavor!
Aj loves cherry tomatoes and eats them by the bucket full in August and September, but I have never been a real big fan of them. I’ve never been one to just eat a plain tomato. I usually prefer my tomatoes in a recipe or at least a sandwich or salad. But Sun Sugar Tomatoes has changed that for me, just writing about them makes my mouth water!!
How many Tomato plants should you plant?
I started my first season off with 2 starts. Two of my Master Gardener friends each gave me a start to try. One of them met an early demise when it had an accident involving and a soccer ball and a trampoline (don’t ask). The other survived to maturity and after struggling to set fruit through our hot summer it finally hit its stride and produced a lot of fruit.
For the first few years that we grew this variety, we planted 2 plants. But we have trimmed that back to one plant now. They are so productive that we were getting overwhelmed with 2 plants and just couldn’t keep up. I would say that one plant is plenty for a family of 4 to 6 people unless all of you really love cherry tomatoes!!
Is a Sun Sugar Tomato a hybrid?
Sun Sugar Tomatoes are a hybrid variety so you WILL NOT be able to save seeds from year to year. But if you are going to grow a cherry tomato, in my opinion, this is the one to choose!! The seeds germinate easily so these are a good choice for growing your own seedlings. Sun Sugars are still not the most well know tomato so you may have to search a little for them. But the seeds are easy to find online from several different seed catalogs. In fact, Sun Sugar Tomato seeds are even available now on Amazon, just follow this link. And for the past two years, we have even been able to find them at our local garden nursery.
