Growing Pomegranates in Containers
Hi my name is Byron Martin here at Logee’s green houses today we’re going to be talking about pomegranates particular pomegranates that grow in pots and can be grown in pots for fruit and for flowers so there are a couple things that restrict us growing pomegranates here in New England one is our temperatures are much too cold for the winter times pomegranates can take it down into the twenties maybe even the teens but not here in New England we go below zero and also we need to have the ability to winter them over and then give them the critical chill that allows them to produce fruit.
So in the world of pomegranates there are pomegranates that will actually flower in tropical areas there are some large fruiting varieties but the fruit is really almost inedible it’s mostly seed and very little flesh around it and then there are pomegranates that need fairly long chill periods of 400, 600, 800 hours of temperatures below 40 degrees during the dormancy in order to get a flower production on them and that really is the critical thing in growing them the warmer ones generally don’t have good quality fruit however there are some what we call low chill varieties that have worked here.
For us in New England and this particular one which is called Big Red came out of South Florida it has a fruit that gets almost as big as that which is in the store a little bit smaller probably would if it was in the ground and remember pots do restrict plants a little bit this has delicious sweet fruit on it fruit gets very red inside it has quite a low chill it’s probably the lowest chill edible variety that we found and you can see it’s got one, two, three, four, five, six a plant like this you probably not grow any more than six fruit.
Being that it’s in a container in the root system is restricted so this plant actually which has come out of dormancy in the springtime covers itself with orange flowers the first flowers are not the ones that carry the ovaries or are female it’s the later ones that actually produce the fruit so you’ll get an abundance of flowers in the beginning and then later there’s this other crop of flowers that come out that actually contain the fruit so don’t be concerned if all your flowers are falling off and no fruit is being held this plant here.
Goes into a dormancy like most pomegranates in the fall drops all its leaves it’s deciduous and then we put it into a cold greenhouse where temperatures are kept just about at freezing, a little bit below freezing and reliably this one Big Red and another variety called Eve has been very good at producing fruit for us, edible fruit in the north in growing container pomegranates we use the standard potting mix for them we do fertilize them during the growing season with a balanced fertilizer on pretty much a constant basis you can use a liquid feed or you can top dress.
And then it’s just a matter of managing the water on them throughout the growing season they’re actually a pretty easy to grow plant, they really are very few pests that affect pomegranates really their root systems are very strong so disease is not an issue there are some problems with the fruit in the North here we have a lot of humidity they kind of get a browning or Calyx rot on the fruit which can actually damage the fruit before it ripens and we also have problems sometimes with them splitting and that’s really a water issue. too much, too little water as they grow in containers.
So thank you for watching today there’s a little bit of information on growing one of our most famous antioxidant fruits the pomegranate and if you’d like a little more information on this you can go to our website at Logees yeah.
