How do I save butternut squash seeds to plant next year?

Wash the seeds to remove any flesh and strings. Cure the seeds by laying them out in a single layer on a paper towel to dry. Store them this way in a place that is dry and out of direct sunlight. Once thoroughly dried, in 3 to 7 days, store them in an envelope in a cool dry place with the rest of your seed supply.

How long do squash seeds take to germinate?

7 to 10 days

Why won't my squash seeds germinate?

Your Soil Is Too Cold Or Too Dry Another reason your squash seeds are not germinating has to do with soil conditions. If the soil is too cold, then your squash seeds might not sprout right away (whether you are growing indoors or outdoors). They may sprout when conditions improve and the soil warms up.

Is it better to start squash seeds indoors or outdoors?

I start some seeds indoors in 4 to 6-inch pots in the last half of April, about 2 weeks before Salem's average last frost, which is in early May. Then, I plant some squash directly from seed outdoors. Squash seeds germinate best when the soil temperature is at least 70 degrees F.

Do I need to harden off squash plants?

Heat loving plants like tomatoes, peppers, and basil, need particular care before transplanting, but hardening off is a sensible step to take with ALL seedlings. We recommend hardening off seedlings over the course of at least several days to one week.

How long does it take to harden squash plants?

about one week

How can I harden my plants without a cold frame?

If you don't have a greenhouse or cold frame, just set your plants outside for increasingly longer periods of time. Towards the end of the hardening off period you can use fleece or row covers to protect foliage against the chill of night.

How do I harden my plants before transplanting?

An intermediate home, such as an unheated greenhouse or cold frame, is a great tool for hardening off. Place seedlings and plants into the structure for a couple of hours on the first day, then gradually increase the length of time they are in place by two or more hours per day.

Should I fertilize after transplanting?

Apply Milorganite fertilizer over the soil surface. Wait a year after planting if you decide to use another type of fertilizer. High nitrogen fast release fertilizer can injure tender roots and encourage excessive top growth limiting root development.

Do you need to harden off plants from greenhouse?

In northern climates, cool spring temperatures, strong winds and bright sun can be very stressful to plants that have been grown in a greenhouse. To minimize these risks to tender plants a process known as “hardening off” is required.

How do I make my seedlings stronger?

Put a small fan next to your seedlings on a timer so that the plants are blown in the breeze for a couple of hours a day and gently passing your hand over the tops of seedlings a few times every day to stimulate stronger growth. Some leggy seedlings can be saved with modified transplanting techniques.

How long can seedlings stay in trays?

around 3-4 weeks

Do seedlings need direct sunlight?

Yes, most seedlings need direct sunlight between 10 – 13 hours each day. If you're growing your seedlings indoors, it's important to grow them in containers and place them in a sunny, south-facing window where they can get adequate sunlight.

How long should seedlings be on a heat mat?

Question: After I've sown the seeds and turned on the heat mat, do I leave it on all night? Answer: Yes. Leave the heat mat on and set to the same temperature 24 hours a day until the seeds sprout.

How big should seedlings be before potting on?

The general rule of thumb is that when a seedling has three to four true leaves, it's large enough to plant out in the garden (after it has been hardened off). When you plant a seed, the first leaves to emerge are the cotyledons. These leaves will look different from leaves that will grow later.

Can you start seeds in egg cartons?

You can use egg cartons as a seed-starting tray! Depending on the type of carton you have, you can even cut apart the individual sections and plant them, as the carton will biodegrade. Be sure to poke small holes for drainage, and put the cartons on a tray or in a shallow pan to catch any residual water.
