Romaine hearts growing in water. I have 6 hearts growing on my window sill.

I love it! Do you add any nutrients to the water? How do the hearts taste comparative to the first head?

Heck, I had them growing in the garden from when I harvested the Romaine. I never tried to eat them though. I figured they would be bitter.

They are not bitter, especially coming from the center of the heart. This will grow up to be "Baby Romaine" like you see in fancy salads. If I plant them into the ground the leaves will get bigger. I might try it. We eat enough Romaine that I have enough to experiment with. However, it needs regular water in our heat and I am not sure I have the time to give it right now. I think if they get bigger they will get bitter.

Does the water need to be completely changed out now and again??

I change it out every other day or even every day. I do the same with green onions. Pic on that later.

I've read the same can be done with celery also.

Actually there are about 15 veggies you can regrow and reuse, some quicker and easier than other. Let's see if I can name them: pineapple, celery, Romaine, green onions, sweet potato, carrot tops (Though you must have a acquired taste for carrot greens), avocado (Got patience?), onion, garlic....I guess I can't name them all.

I never knew you could eat carrot tops but just Saturday at market one of the vendors told me she puts them in her baked goods. I knew she used chard and spinach, but not carrot. She makes "healthier" baked goods and you can't even taste it!

Beet tops are good if prepared right, as are turnip greens. Kale is becoming ever so popular, too. Greens are healthy for you, and easy to grow. Plus, with some greens you get to have the root veggie part to eat, too! SCORE!

Yes, we sell a lot of baby beets for both the root and people are juicing them. Luckily they aren't all full of holes this year!

I usually just let the romaine go to seed and collect the seed for the fall as it's too hot here in the summer for romaine.

Jan, now you can grow fresh Romaine on your window sill during the hot summer months! I hesitate to plant these starts outside right now. We got 100* or close to it in the summer. It's 90* in the shade!

I will try it next season. My birds miss it when it's out of season here too.

Actually, Jan, you can grow Romaine in water anytime of year as long as you have a bright, not necessarily sunny window sill. Start with a store-bought head of Romaine and you are set to go.

Never thought of that. Thanks

Are you starting with store bought lettuce which was hydroponically grown and still has roots attached?
or just regular romaine?
By the way, I love your 'onions in water' idea!

I just started with regular Romaine and made them hydropotonic for their next life. Roots will grow, the heart will shrivel up. I haven't tried to give it a third life after "harvest". The hearts just don't look as good but I might. I haven't seen hydroponic Romaine, but have seen Butter Lettuce. Might have to try that!
