I think my San Marzano tomatoes are one of our most highly anticipated crops, and also probably the most difficult to grow so far. Last time I posted I mentioned how they had just started flowering, and fruit was beginning to develop, as well as how we were fighting an edema issue.
The tomato bushes are now massive – actual bushes. I cant even get a proper photo of the entire plant in my grow room; the camera doesn’t have a wide enough lens.
Can you believe that I cut off a whole armload of branches off this plant every couple days?! Its insane just how fast they grow new leaves.
Fighting Blossom Drop
The tomato is still flowering, a lot. The biggest issue is I have blossom drop. There are a couple reasons for blossom drop such as incorrect temperature and humidity, or that they are not pollinating correctly.
I have checked my temperature, and the grow room is sitting in the ideal range. So I suspect that perhaps the flowers aren’t pollinating as well. I did get sick and stop using the electric toothbrush method as often, so in the future I am going to be a bit more precise in application – vibrate those leaves until you can see the pollen dust emerging from the flower heads.
In the last post we had the subtle-hints of fruit emerging. Well it’s safe to say that they have emerged!
We have about 14 tomatoes growing so far. Not as many as I had hoped for, but as mentioned above we had an issue with blossom drop. There are plenty of flowers on the plant with many more emerging regularly, so hopefully we will be getting more fruit over the coming weeks.
