Can you use some help on how to grow squash? Summer reminds me of fresh air, planting seeds, pulling weeds, and harvesting vegetables for several months. There is something awesome about growing your own food, and squash is one of my favorite vegetables. Mark is not fond of it, but I love it!

Summer squash is super easy to grow even when you start with seeds. Yes, you can buy plants, but I will tell you this, my seeds grow so fast I quit buying plants years ago. I still buy a few tomato plants, but way less than I used to buy. This is where I buy my seeds: SeedsNow

Summer vs. Winter Squash

Today I’m talking about summer squash. The main difference between summer and winter squash is this, you pick summer squash when it is tender. Winter squash, you let the rind harden on the vine. We all laugh when we see those zucchini grow into torpedoes, right? It’s crazy, you check the garden today and tomorrow those tiny squash are 8 inches long and ready to pick. The most popular summer squash varieties are zucchini, yellow straight neck, and yellow crookneck.

Soil Amendments

Before we get started with the planting seeds, let’s be sure your soil is ready. Here are my tips for soil, I do this every Spring and Fall.

The first thing we need to do is pull any weeds that have come up since the last time you turned over the soil. Dig out any leftover crops that you may have missed the last time you harvested. Turn the soil several times and add the following amendments, if you need them.

Soil pH Levels

What Does The Term pH Level Mean

Are you wondering what the term pH level is when gardening? Each plant prefers a different level of acidity to grow the very best harvest. The level of acidity desired varies between each plant variety. Therefore, you can adjust the pH of your soil by adding lime or sulfur to bring it up or down depending on what your soil needs. You can have your soil tested, possibly by your state extension service, or try and do it your self with a soil tester. pH Tester

How To Hand Pollinate

All you need is a paintbrush. If you need to hand pollinate because you are not seeing any fruit develop here is something you may want to try. You do this by removing the male blossom (male blossoms do not have fruit behind them). They produce pollen leaving the center covered in the pollen to collect with the brush. Use a “brush” to apply the pollen you collected to the center of the female flower. This works for squash, melons, and cucumbers every time.

Plant Squash Seeds

Summer Squash: zucchini, crookneck, and straight-neck (harvested in the summer before they reach maturity).

Winter Squash: pumpkins, butternut, spaghetti, and acorn squash (harvested in the autumn months after they reach maturity).

When you plant the seeds, test the soil to make sure it is at least 60 degrees F. before sowing your seeds. They need full sun exposure. They need loamy soil rich in nutrients. The soil must drain properly. Plant the seeds in hills (2-3 seeds each) one-inch deep. Space them 2-3 feet apart. Thin as needed to produce the strongest plant. Use a cloche to keep the plants warm in case of cool weather. Mulch the plants to keep them moist and weed free. When the first blooms appear, fertilize the plants.

Water deeply at least one inch of water per week. The soil needs to be moist 4 inches down. If your blossom ends turn black and rot, then you have blossom rot. It’s usually caused by uneven moisture in the soil. It could be a calcium problem. Water must be consistent and frequent for the fruit to produce. If the fruits are misshapen they may not have received enough water or fertilizer. Check for fruit you can pick daily, they grow faster than you may think.

pH level for Squash: 5.5-6.8

Squash Problems

Squash Bugs

You may have seen these small, tiny, flat, brownish-gray bugs underneath the leaves and near the crown of the plant. They lay copper-brown colored eggs. The bugs are about 1/2 inch in size. Keep an eye out for a full-blown infestation. We have to keep on top of this pesky bug. The eggs hatch every ten days, you can scrape the eggs off with a butter knife. Dispose of them in a bag tied tightly in the garbage. You can use row covers to try and keep from getting them. You roll out the cloth and place rocks or bricks to keep the cloth in place.

Powdery Mildew

It makes the leaves look like they are dusted lightly with flour. You will see blotchy white patches spread out on the leaves. It mainly shows up on the upper leaves but may show up underneath the eaves as well. I have used white vinegar mixed with water to spray the fungus. I use 2-3 teaspoons vinegar (5% acidic) to one gallon of water in a spray bottle. Spray often.

Poor Soil

Summer squash needs good soil, if you use good organic compost and mulch you should be fine. I use 2 cups of 16-16-8 fertilizer per 50 square feet of garden.

Blossom End Rot/Vine Borer

Inconsistent watering may cause blossom end rot. If they don’t get enough water then a calcium deficiency may occur. If the plants suddenly die, it may be the vine borer. Keep an eye on the main center section of the plants. The vine borer eats through the stock and you will see sawdust like crumbs. They fly in the day and are black and red with dark wings.

Lack Of Water

Here you walk a fine line, don’t water too much, but water enough so the plants thrive. They need about an inch of water each week. If you dig down in the soil about 3-4 inches check the soil, if it’s dry, it’s time to water the plants.

Not Enough Sunshine

Squash needs a minimum of six to eight hours of full sun each day. If the plants are lanky and stringy they are lacking the sun they need. If the leaves are a very pale green color that is another indication of needing more sunshine each day.

Final Word

I hope today I get you excited about growing a garden. The last three years I have had trouble growing squash, as in zucchini. I thought to myself, no one on earth has trouble growing zucchini. Well, I did. But not anymore once I learned why my plants were not producing. They needed my help by pollinating them by hand. Yes, it’s easy and you can do it too! All you need is a sable paint brush. It’s all about being self-reliant. May God bless this world, Linda
