Of the 82 seed packets we ordered earlier this year, we have planted nearly all of them, with only the fall crops still remaining. So, I wanted to write two articles: one on the hardest seeds to start and a second on the easiest ones.
I’m starting with the hardest seeds. My experiences with these are just that – my experiences – and are in no way an indictment on them or the seed companies they were purchased from. I could have done something wrong that caused failure, and if you’re curious about them, you should still buy them. Without further ado, here they are.
5.) Principe Borghese Tomato
We bought these seeds to be our paste tomatoes for the year, opting for this heirloom Italian variety over the more popular Amish Paste or San Marzano. We were intrigued because of their history, that they could also be sun-dried, and because they were spherical rather than the typical oblong. Unfortunately, we had nothing but problems with them.
I started these seeds the same way and at the same time as all the other tomato seeds; however, for some reason, these didn’t germinate as well as the others, and the ones that did germinate got leggy within a few days. Side note: Nearly all our tomato starts got leggy due to inadequate lighting, but these starts were worse than the others. When I attempted to harden them off and transplant them into the garden, none of them made it. To be fair, only one variety of tomato plants successfully transplanted due to poor weather conditions, but these were the worst. Later, I attempted to direct sow them in the garden once the soil temperature was warm enough, but it’s been at least two weeks now, and we’ve seen no signs of germination. These seeds not working is disappointing because we were excited about them. There’s a good chance we’ll try them again in the future, but we’ll buy a second type of paste tomatoes if we do.
4.) Calabrese Broccoli
We wanted to grow broccoli this year despite having no experience with it. We chose the Calabrese variety because it is supposed to be a traditional-style broccoli that produces smaller heads and multiple side shoots. Everything I read made me confident that it would grow well in our area. I started them indoors 4-to-6 weeks before the last frost, as the seed packet suggested.
The seeds germinated well, but the new starts immediately struggled. I didn’t know this at the time, but broccoli is sensitive to warm temperatures. That is something I struggled to monitor and control with our seed-starting setup because I started vegetables with different temperature requirements at the same time. Additionally, our current grow light gives off heat but needs to be very close to the plant to provide enough light. This created a lose-lose scenario. Understanding this, we may direct sow late in summer for a fall crop. I think this will result in a better growing experience, but it’s anything but a “set it and forget it” seed.
3.) Husk Tomatoes – Ground Cherries & Tomatillos
I’m combining these two because they’re part of the same husk tomato family, grow in similar manners, and seem to be susceptible to the same issues. This is another vegetable/fruit that we’ve never grown before. Actually, we don’t think we’ve ever eaten ground cherries before and have only had tomatillos in salsa. We had similar issues with these that we had with other seeds: When they germinated, they went leggy pretty fast. One difference, though, was that these seeds took a long time to germinate and were slow to grow after they did.
When it became clear that getting any fruit off our starts was going to be a struggle, we bought a plant of each at the local greenhouse. They were very healthy and already had fruit forming. We transplanted them into one of our garden beds and quickly encountered issues. It started with the three-line potato beetle that required a non-organic spray to treat and has only continued with the plants struggling to grow. I think it’s the result of too much moisture in the soil, but as a bright spot, our ground cherry plant is still producing fruit, and last evening, we were able to harvest one. It wasn’t ripe enough yet, but it was rewarding to get something from it.
We also bought a few more tomatillo starts and transplanted them into a different garden bed with better drainage. I preemptively sprayed them to prevent beetle infestation and staked them. They’re still doing very well with dark green leaves and fruits that continue to develop. We’ve learned a lot since we first started these seeds, and we’re certain that 2025 won’t be the only year we grow them.
2.) Ping Tung Eggplant
We gave these seeds a shot because they were unique compared to the Italian eggplant that is more common in the United States. These originate in Taiwan and have a more cylindrical shape compared to the bell shape of the Italian style. Before purchasing, we were aware of the struggles that some gardeners have experienced with these seeds. Some talked about the issues of successfully moving from germination to transplanting. That’s the same problem we had. They germinated quite well, but like other plants, they quickly went leggy and died. I tried restarting them in May, but they didn’t even get past the germination stage. It’s quite a bummer.
We bought two eggplant starts from the greenhouse, and they’ve been doing very well since being transplanted. I don’t think they’re Ping Tung eggplants, but they are an Asian variety. They have been flowering for more than a week, and several fruits are beginning to develop. We were also gifted an eggplant start from our neighbor. We were unable to transplant it right away, so the plant was looking unhealthy by the time it was transplanted, but it has since recovered and is growing nicely. The Ping Tung seeds may just be difficult to start; I’m unsure, but I think we’ll give this variety another shot in the future, either this fall or next spring.
1.) Ishakura Bunching Onions
The final item on this list is an Asian-variety bunching onion seed. We chose these because we like Asian vegetables and were intrigued by being able to grow onions in the spring. Like the Ping Tung eggplant seeds, there were some mixed reviews from gardeners, so I knew there was a chance of some issues. I attempted to start these inside, which is what the seed packet recommends. In fact, it says to start these up to three months before the last frost date, so I had an expectation of slow but consistent growth, because it’s hard to keep starts going that long without needing to transplant them.
I began them in normal seed cells and had successful germination in the expected timeframe. They grew to about three inches and then stopped. They didn’t grow any taller or thicker. I thought that it could have been part of their growing process and that they would take off after being transplanted, but that wasn’t the case. Transplanting them was difficult due to the fragile root structure, and none survived. I later attempted to direct sow a row of them in the garden, but none germinated. This seed was easily the most disappointing of the season. Part of that is because we were excited about these onions and never experienced a hint of success.
I think part of this was the result of poor growing conditions. I think that growing them in a container would yield better results. You can tightly pack these seeds in, so in a 12″ diameter pot, you can probably grow two or three dozen plants. This would also allow for better moisture management. Still, for how easy the seed description said they were to grow, these were a letdown.
Giving Up or Trying Again
This is the decision we’ll find ourselves with next spring. Do we give up on these seed varieties and buy a different seed or a start, or do we try again with the knowledge we didn’t have before? It’ll likely be a combination of both. We had a conversation last evening about these seeds, and we are unsure if we’ll buy husk tomato seeds next year. They’re quite difficult to start, and the starts are very affordable. That doesn’t mean we won’t try starting them from seed again in the future, but I want to have confidence in successfully growing them to harvest before going back to the starting point again. The Calabrese broccoli seeds may be the same way.
But I think we’ll buy the bunching onions, Principe Borghese, and Ping Tung seeds again. I can pinpoint what went wrong with all of those, make changes, and be confident that we’ll have a different result. We’re going to upgrade our growing light, which will help, and our weather this spring was unusually bad. An improvement back to the norm would have a big impact.
I am planning on doing this article each year as we try new seeds. I’m also going to be doing a post on the five easiest seeds to start. Happy gardening!
