No Flowers on My Hydroponic Tomato Plants

I'm growing tomatoes in an hydroponic Aerogarden in my house. I have great plants, but no flowers. I've checked with the company and still I have no flowers after doing everything they recommended. Can anybody help?

You may have to prune off some leaves. This will force the plant from a vegetative state to a generative (fruiting) state.

I have not had a hydroponic "garden" for many years but I do remember that some plants do not "self pollinate" and will not fruit if this is not done by hand.

  • Hydroponic plants usually need about the same care as their sister outdoor plants but maybe handled or applied in a different way.
  • It seems tomato plants need more space in a hydroponic system than most plants so that is one consideration.

  • When you started adding nutrients could be another problem (if you are adding bloom nutrients?).
  • Pollination may be the biggest problem. Tomato plants grown in this kind of system will have to be hand pollinated or you can use a very gentle fan to distribute the pollen.
  • I would check out some sites that have good instructions on hydroponics as I would not rely just on instructions from the Aerogarden company.
  • Here is a site that might have some additional information.
  • Maybe just read and see if you notice anything that you have not tried.

Hydroponic tomatoes sounds like fun! It's been a little while since we had some, but I'll try to tell you what I remember....You may want to make sure that your nutrients promote bloom. You can also trim some back and make sure that your plant doesn't have any suckers. The suckers are the spindly shoots coming out from the joint of the main plant and the leaf stems. The blossom stems will also be coming out of the main stem like the leaf stems.


Sometimes it can be tricky to catch when they bloom because the blooms will fall off if not pollinated fairly right away. Most tomatoes do not self pollinate so you either have to have bees of some sort to pollinate or you must hand pollinate. I used to use a small brush to gently brush some pollen from 1 blossom to the next and I would do it a couple times around to be sure I spread it well so I didn't get odd looking fruit.
Good Luck! I hope your plants start blooming and producing for you!

Some Hydroponic tomato plants will flower sooner than others. But basically you'll need to trim these plants and use some fertilizer to help promote flowering.


Being an indoor plant you'll need to work out a system to pollinate the flowers once they bloom on the plant. Otherwise, you won't get tomatoes off of these at all.
