Rhubarb is a beautiful vigorous plant that comes up faithfully every spring and gets bigger and bigger each year. It will send up a huge stalk with a not very pretty bloom on it but you shouldn’t let Rhubarb bloom. Cut back the blossom stalks to the ground to keep the plant vigorous and producing. Also, the leaves contain high levels of oxalic acid and are considered toxic. So when you cut the stalk to eat be sure to cut the leaf off immediately since the poison will travel into the stalk once cut. Actually the leaves can be simmered in hot water to make an insecticide.
The stalks are delicious in pies and you can dip the raw stalks in sugar and eat like celery. This is really good and kids love it. It is high in Vitamin C and Calcium.
Rhubarb is one of the most carefree plants to grow. It does best where the winter temperature goes below 40′ and the summer highs average around 75-80. Don’t harvest any stalks the first year and only a few the second year. But after that you can harvest up to 1/2 the plant. Stop harvesting though when the stalks become thinner because it means the roots are getting weaker.
Since we really enjoy more tropical settings than we are able to have where we live, it’s fun to use some plants that look tropical, like the rhubarb with its big, leathery leaves. We are even trying to grow some palm trees, but I think that is pretty optimistic of us. Maybe some of them will make it though, if we can have a few milder winters until they can get established.
Thanks and happy planting!
