Grow at Home: How to harvest pumpkins. Is my pumpkin ripe?

Is my pumpkin ripe?

multi_coloured_pumpkinWhat colour is a ripe pumpkin?  The answer is ususally orange but they can come in shades or grey, blue or white and some are even stripey.

But generally colour is a pretty good indicator - if it is orange all the way round then it is pretty likely to be ripe.  However, it you've grown something a bit different then it is important to hold on to the seed packet so you know what colour to expect.

Whatever colour it is there are other ways to check if your pumpkin is ripe though.

  1. The Rind - the rind will be hard if the pumpkin is ripe. To test its readiness try to pierce the skin with your fingernail.  It should be strong enough to resist puncture so if the skin dents but doesn’t puncture, the pumpkin is ready to pick.
  2. The Sound - a ripe pumpkin will sound hollow.  So try tapping it.  Listen for a hollow sound and that will tell you that it is ripe.
  3. The Stem - when the stem above the pumpkin becomes hard this is another indicator that your pumkin is ripe.

How to harvest Pumpkins

Harvesting correctly is important if you want to store the pumpkin for later use. There are some key steps.

  1. Try and harvest when it is ripe.  Pumpkins harvested too early will still ripen but are more prone to rot.  You may want to harvest early if there is a chance of frost but otherwise try and leave them until they are ripe
  2. Pick a dry day - pumpkins harvested when wet are agian more likely to rot.
  3. Use a sharp knife so you do not leave a jagged cut on the stem.  A jagged cut will allow disease to get into your pumpkin which could cause it to rot.
  4. Leave at least several inches of stem attached to the pumpkin.  Again to prevent disease.
  5. Clean the pumpkin - after you harvest the pumpkin, wipe it down with a 10 percent bleach solution to kill any organisms on the skin. You might want to rinse it before eating but the bleach solution will evaporate in a few hours so will not be harmful.
  6. Store in a cool dark place out of direct sunlight.  Pumpkins will continue to ripen once off the vine (see section below) so if yours is already ripe it needs to be out of the sun.

Will a pumpkin ripen once picked?

If you wondered, do pumpkins ripen after picking? Then the answer is Yes.  If your pumpkins are still green, there are a few things you can do to ripen them.  Especially useful if you want them nice and orange for Halloween.

The speed a pumpkin ripens at - both on and off the vine - depends on the temperature and the amount of sun it gets. Its fairly logical: quicker when its warm and the sun is out and slower when it is cold and dull.

Sun

So even after pumpkins are picked they need as much sun as possible.  The best place to put them is an open space facing South.

Make sure the pumpkins are kept free from dust and dirt by wiping them occassionally.  You don't want anything blocking the suns rays, especailly if those are few and far between.

Make sure that the sun gets to the whole pumpkin by rotating them every day.

Temperature

Another problem with ripening pumpkins is the weather. Temperature drops will cause ripening to slow.  If possible, move your pumpkins inside the house on nights when temperatures drop below freezing. Returning them back outside if the weather is set to be sunny.  Or, if there is no sign of good weather store the pumpkins inside in a warm, airy room with large windows and plenty of direct sunlight. This way the pumpkin will continue to ripen.

The best storage temperature is a cool 10-12° C (50-55° F)

A healthy, disease free pumpkin can be stored for 8 to 12 weeks.

Your traditional Halloween Jack-o-lanterns don't last as long though.  Possibly due to the size but you are looking at a week to 10 days for these.  As an aside, if you are carving and not eating them then giving them another 2 minute soak in bleach solution once carved will also prolong your art work over Halloween.
