Spaghetti Squash Growing Stages

When you are growing your spaghetti squash, it is vital to know its growing stages so that you can cross-check your plans to see if they’re doing well. Let’s look at the stages of growing spaghetti squash.

Stage 1 – Starting Spaghetti Squash From Seed

    • To start your spaghetti squash seeds, you will need to wait for the warm climatic conditions to set in early spring. You will require a long growing season with one climatic condition that will include warmth when planting. That said, the spaghetti seeds should be sowed after the last frost date has passed.

    • Most gardeners have a standard way of starting their spaghetti squash seeds indoors as they wait for the frost date to pass and the soil to warm up.

    • If you start your seeds indoors, ensure you do so a month to the last frost date in your area. Your seedlings will germinate and at least get some leaves in a month. Use large containers when starting them indoors instead of small seed trays.

    • Put 3 to 4 seeds in each container that has the size of about 3 inches wide. Sow each seed at a depth of 1 inch under the soil. Place your pot’s location where it warms up to help with proper germination when sprouting.

Stage 2 – Transplanting Your Spaghetti Squash Seedlings

    • After the frost is over, you will have to wait for at least 15 days to transplant your seedlings.

    • If you have cold weather conditions, you can lay back a black plastic on the ground of your garden to warm your soil before transplanting.

    • You may also consider growing spaghetti squash in hills or raised beds.  You can grow your squash vertical to save you space, but spaghetti squash is not a good idea. The fruits of the spaghetti squash are not too big and don’t look good if you offer support to them on the vine when they’re hanging mid-air.

    • When you are ready to transplant, ensure that your soil is loose enough to take in a sibling and add some aged compost manure before planting. Squash labs soil has a good amount of nutrients as it is a heavy feeder.

    • Ensure the location that you are transplanting your spaghetti squash has full sun and space them at least 3 feet apart per hill. If you experience too much sun, it is advisable to provide them with at least 6 hours of sun and partial shade.

Stage 3 – Care And Maintenance When Growing Spaghetti Squash

Once you have planted your spaghetti squash seedlings, it is time to take care of them.

    • After the hot summer has passed, you will need to take off any new flowers produced by the squash vines. This is because there isn’t sufficient time for them to reach maturity, and the plant’s resources will be used in a better way to grow the squash that is already developed on the vine. By doing this, your squash will be growing in the complete season.

    • Provide good mulching or lids for your fruit to protect it from the rot that comes from being laid on the soil.

    • Keep your spaghetti plants well-watered and free from weeds as the leaves develop. Once the leaves are completely grown, they will start shading the soil surrounding them, eliminating the weeds without your help.

Care And Maintenance When Growing Spaghetti Squash
    • To help save your space, try to plant a variety of squash as a bush. Select the types that do well as a bush or vines, depending on the amount of space you have.

    • If you are growing your spaghetti squash in a large pot provided with at least five gallons of water every day for every plant.

    • Provide your spaghetti squash with a bit of feeding during the growing season to replenish any nutrients the soil may not be providing.

    • The most common pests that affect spaghetti squash are cucumber beetle and squash bugs. These are sufficiently big and can be taken of your plants using your hand immediately you spot them. Ensure that you check the lower and upper sides of the leaves, looking for pests.

    • Remove every weed as it commonly encourages mildew if the climatic conditions are damp. Mildew looks like white powder dust on the leaves and affects the development of your plant. Use fungicide sprays to help clear this mildew, and you can also prevent it by watering your squash plants at the soil base rather than sprinkling water leaves.

Your plant should be growing well at this stage.

Stage 4 – Harvesting Spaghetti Squash

    • Push your nails into the external skin to check if your spaghetti squash is ready for harvest. The skin of a spaghetti squash needs to be sufficiently tough to tolerate your fingernail full stop; if the skin is light and gets punctured quickly, your squash needs more time to grow.
