AeroGarden tomatoes must be pruned early and often in order for them to grow full and bushy, as well as to flower prolifically. If tomatoes are not pruned early enough in their growth, they will grow tall with lots of leaves and flowers at the top, but no growth on the lower stems.
Here are before-and-after pictures of an overgrown Cherry Tomato Seed Kit. In the first photo you see the overgrown plant before being cleaned up and pruned. In the second photo, the right rear plant has been removed (it was dead), and the other two plants:
As your tomatoes begin to send new shoots out at the top, prune them off again. When pruning the tops, look for the newest, smallest leaves, and make sure you remove these. The growing tip is not the actual highest part of the plant, but just a little below that, in the V where one stem branches off from another. The next photo shows the growing tip (in the V), with the pencil pointing to where the plant should be pruned.
Keep pruning the new growth off the top about every two weeks, making sure to remove the growing tip. After the plant determines that growing upward is not an option, it will send out new branches lower down on the stem. Keeping the tops pruned down also allows more light to reach the new leaves that will form at the base.
Keep training it this way until the plant has developed a more compact shape, and it will then begin to flower throughout its height. Here are two photos of the middle plant that was pruned above. The first was taken one week after pruning the top, and the second photo was taken three weeks after the pruning. Note how much new growth there is at the base of the plant.
Below is a photo of the same tomato plants shown in all the photos above, five weeks after being pruned and moved into an AeroGarden Extra Elite (Pro 200):
Below is the same AeroGarden, 14 weeks after the meristems were pruned (at approximately 30 weeks of age). It yielded 163 tomatoes off the two plants. These are our regular Golden Harvest Cherry Tomatoes (not the Mega Cherry):
