Butternut Squash Seeds.

Filed under: unusual veg — Tags: , , — TopVeg @ 6:23 pm

The time to sow Butternut Squash seed is when both the air and the soil
have noticeably warmed up and the risk of frosts is past. But it is
possible to start squash seed indoors 4 to 6 weeks earlier.

The seed will only germinate in temperatures over 60F, & the shoot will
take between 1 & 2 weeks to emerge.

If starting off indoors:

* plant 3 seeds in a plant pot (10cm in diameter), point bit facing up.
* Cover with some clingfilm and put on a frost-free window sill.
* Remove the weakest seedlings to leave the strongest 1 or 2 in the pot.
* They will be ready to plant out when they have 3 leaves.
* Don’t rush because squash like warm soil and will be killed by frost.
* Introduce them to outside conditions gradually, by putting the
pots outside during the day for a bit, so they harden off.

  1. Hi
    I have planted a butternut squash seed in a pot in my kitchen on the window sill. I now has many leaves and is growing too big for the window sill, Is it too early for me to put outside? I do have a summerhouse but its not warm. Thankyou for the tips on your web site
    Pamela.

  2. Hi Pamela

    It is really not warm enough for the squash to go out yet. It is obviously happy on your kitchen window sill – perhaps the summer house is the best bet – as long as it has plenty of light, & if you can protect the plant from frost – buckets of water in the room may help keep the temperature up be a few degrees if frost is forecast.
    It is a real dilemma in this country, as butternut squash need a long growing season to fruit. So starting them off indoors gives them a headstart.
    Have a look at the post ‘How to Grow Butternut Squash ‘ (http://topveg.com/2009/10/how-to-grow-butternut-squash/
    which may help.
    Can you start another seed off in a few weeks, just in case this one does not make it?
    Good luck TopVeg
