Young zucchini plants often produce only male flowers for the first week or so, resulting in no fruit set. .
Zucchini Flowers but No Fruit! – The Veggie Lady
It’s very frustrating to see the hope of future produce, only to be greatly disappointed when your vegetables don’t grow to maturity.Cucurbits include zucchini, courgette, summer and winter squash, pumpkin, melons, cantaloupe and of course cucumbers.Successful pollination of the male and female flower is imperative for the plant to produce fruit that will grow and mature for you to pick and eat.While it might look like you have some little fruit developing, it doesn’t continue to grow and will soon turn yellow and die.Make sure you always have lots of flowers, with different shapes, different sizes and different colours all year round.And don’t forget to watch out for other problems you can have with leaf eating ladybirds on your cucurbits. .
The Secret to Success With Zucchini
Believe me, it can be frustrating if every gardener you know is moaning about their zucchini glut when you've only managed to produce a few fruits late in the summer!Zucchini can't cope with cold temperatures, so don't start them off too early - check recommended sowing and planting out times for your location in our Garden Planner.For zucchini to be highly productive they need plenty of fuel in the form of nutrients from the soil and sunlight to help them photosynthesize efficiently.My theory is that this draws in insects such as bees who will return to the plants once the female flowers are produced, and this will enhance successful pollination.Stressed plants may also abort their fruits, so make sure you keep them well-watered and protect them with fleece or similar if the weather turns cold.Zucchini may also be affected by powdery mildew in hot, dry weather, which is fortunately simple to prevent by using a diluted milk spray.I like them best roasted along with other vegetables and added to pasta, but they can also be grilled, fried, baked, stuffed, grated into sauces as a thickener, sliced thinly into salads, or made into fritters or zucchini bread.If you have any tips for growing a great crop of zucchini, or for using up a glut, we'd love to hear them - please share them in the comments below. .
Zucchini Not Producing
A customer came into the store last week, concerned that she wasn’t getting any zucchini from her summer squash plants.Although it does occasionally happen that a summer squash will produce all or mostly male blooms, if you have more than one plant it’s unlikely that this is the reason for the lack of production.If you’re using a sprinkler, water deeply every five days so that on the other mornings the bees have access to your squash flowers.Sometimes there are female blooms that are getting pollinated but because the plants are getting watered daily the young squash rots before it develops.The guys are just anxious to get things going, I guess… patience usually ends up paying off, however, and the female flowers appear as the plants get older. .
Why Is My Squash Not Fruiting?
Most squash are monoecious, meaning that a single plant produces both male and female flowers.Recall that female flowers have a small bulbous growth at their base, which will eventually develop into the squash fruit.Locate female flowers and gently dust inside them, as if you were a buzzing bee.Squash don’t always produce male and female flowers at the exact same time.If there has been unusually high amounts of rain or cold weather, this can delay the emergence of the female flowers by a bit.This sort of subpar weather can also impact the activity of pollinators, which is another reason to hand-pollinate squash. .
How to Pollinate Zucchini by Hand
Blossoms drop differently, depending on whether they’re a male or female flower.Other reasons for plants dropping their blossoms include too little or too much water and poor soil conditions.(If you prefer, you can also leave the male flower in place and use a cotton swab or small paintbrush to make the pollen transfer.).Before long, you’ll have to get busy and use your hands in another way–to start picking the bushels of fruit and using them in the kitchen. .

11 Common Zucchini Growing Problems
Zucchini are nothing if not prolific, and while you’re more likely to see a vine take over half your garden than you are to see one struggle and die, they still have their share of potential problems.They can cause problems ranging from a little leaf discoloration to a completely dead plant.The most common signs that things have gone awry with your crop that you’ll see involve problems with the leaves and blossoms.Here are some things to watch for, including potential causes and workable solutions.At planting time, make sure to work plenty of organic matter into the soil.Damping off is caused by a variety of types of fungi – most commonly Pythium, Rhizoctonia, and Fusarium species.If your plants succumb to damping off, with any luck, you will still have time to start a new crop this season.You’ve managed to get your seeds to germinate, but now your little seedlings aren’t looking so good.Damping off in seedlings is caused by the same fungus or mold – typically Pythium, Rhizoctonia, and Fusarium – that can attack seeds and prevent them from germinating.It’s important to keep your tools, hands, and containers clean to avoid introducing any of these pathogens.It can also be spread by fungus gnats, so either cover seedlings, or keep a close eye out for tiny bugs flying around your plants.When zucchini leaves start to curl or become otherwise deformed, the first thing you should look for are aphids.Aphids are tiny, pear-shaped, yellow, pink, brown, gray, green, or black bugs that congregate in groups on the undersides of leaves.They suck the sap out of the stems and leaves, causing stunted growth and deformity.The first step in getting rid of these pests is to blast your plants with a strong spray of water from the hose.Often, if you knock aphids loose, they might not survive the deluge or they’ll move on to other plants.Finally, if your plants are still struggling, apply a neem oil spray every two to three days for two weeks.Since the virus can overwinter in weeds in the soil, make sure to clean up your garden bed at the end of the year.If this disease strikes early in the season and you live in a warm climate, you may still be able to get another crop in the ground in time to produce a harvest.If part of your zucchini plant is growing as happy as ever while other random sections are wilting, you likely have a pest problem on your hands.These little pests look like fat, white worms with brown heads, but you’ll only spot them if you slice open an infested vine.Squash bugs, Anasa tristis, are another pest that can cause wilting leaves.Typically, these bugs cause other, more obvious damage, like ragged holes and yellow or brown spots on the foliage.In addition to causing leaves to wilt, they can stunt plant growth and reduce fruit yields.I find the best way to tackle vine borers is to sprinkle diatomaceous earth around plants.But if you know these pests have been a problem in the past, get a jump-start on them next year and apply Bt as a preventative measure.If you find adult squash bugs in the garden, place cardboard on the ground around plants and leave it out for one night.The next day, grab the cardboard and crush it between two flat surfaces, wrap it in a plastic bag, and dispose of it in the garbage.You can also use pesticides containing permethrin, carbaryl, bifenthrin, or esfenvalerate, though this works best right around the time the eggs are starting to hatch.To tackle cucumber beetles, use yellow sticky traps or just go outside and vacuum your plant.If you step outside to check on your garden, only to find that your entire zucchini plant looks decidedly wilted, there could be a few problems that you’re facing.Try giving your plant a good soak with the garden hose and cross your fingers that it perks up.As mentioned earlier, they’re light brownish-gray as adults, and the females lay egg clusters in orderly rows on the undersides of leaves.A little powdery mildew isn’t a big deal, but if it spreads, it can kill the leaves of the plant and reduce the final fruit yield.This common disease is caused by a fungus, Podosphaera xanthii, and usually shows up in mid- to late summer because it likes warm, humid weather.Once you find your plants have it, the most surefire way to tackle powdery mildew is to apply a sulfur-based fungicide according to the manufacturer’s directions.You can also use neem oil or a biological fungicide like CEASE, available from Arbico Organics.Keep a close eye on your crops, so you can tackle the problem before it spreads, if powdery mildew rears its ugly head again.You head outside to check on your thriving zucchini plant, only to discover that the blossoms that looked so healthy yesterday have fallen to the ground.The most common cause of flowers falling off the vine is that they are male blossoms that have already done their job.It’s hard to tell the difference between what might be evidence of poor pollination versus a normal pattern of male flowers falling off.As mentioned earlier, zucchini plants produce both male and female flowers.A pollinator carries the pollen from the male to the female blooms, and a little while later, a baby zucchini is born.If pollinators don’t visit your plant, the best solution is to take a cotton swab or small paintbrush and do the job yourself.If you did it right, within a day or two you’ll see a thick green bulb form at the base of the female flowers.Blossom end rot is caused by a calcium deficiency, but tossing a bunch of eggshells in the garden after you notice signs of a problem isn’t going to help.Supplementing your plants with calcium after the fruit has already formed and started to show signs of a deficiency won’t work.But you can prevent this disease from destroying future fruits on the same plant if you have a long enough growing season.You don’t need a fancy tool to gauge this, just stick your finger into the soil, 2 inches down. .
