Take Time and Effort Out of Watering Pumpkins in Hot Weather With This Surprisingly Simple Trick
This clever watering technique helps keep plants hydrated when temperatures rise
June is a traditional time for gardeners to plant pumpkins and squashes out into the vegetable garden. What is vital to success is that the crops need consistent soil moisture around the roots, and I have two tricks that I have found make a difference when watering these plants.
Neither of these hacks is complicated. One is to plant a pot in the soil next to the plant, so you water into the pot and it delivers moisture to the roots. The other is to mark where you planted the crop, so you know exactly where to water, as it can get confusing when pumpkins produce all their vines and foliage.
When you are growing pumpkins or squashes, it takes mere seconds to dig a pot in the ground and mark the spot with a short bamboo cane. These two simple tricks help with watering pumpkins in hot weather. They make a big difference to how efficiently you water the crop, and give you a plentiful harvest.
Why Pumpkins Need Regular Watering
Pumpkins and squash plants need consistent watering to develop their vines and produce fruit. Many common issues growers experience throughout the season can stem from watering problems – but there are ways to alleviate them.
The plants have two particular traits that contribute to their need for regular moisture throughout the season.
Firstly, plants have shallow roots. Pumpkin roots inhabit only the top 12-18 inches of soil (it can be just 6-12 inches for squash plants), making them more susceptible to drought stress than crops with deep roots that can access moisture deeper in the soil.
The crops need the top zone of the soil to be moist, and those top inches can dry out quickly during hot summer days. Also, the plant’s large foliage actively loses moisture on hot days.
For an abundant harvest of pumpkins to pick, they require an inch of water weekly, though this demand jumps to two inches when the summer heat escalates, or fruits begin to swell. If you have any aspiration to grow a giant pumpkin, feeding it lots of water and nutrients is essential as the fruit develops.
Maintaining consistent soil moisture is vital for the overall health of your crop; a lack of hydration often results in stunted vines, wilting foliage, or yellowing pumpkin leaves - a clear distress signal that your plants are struggling.
That is where any aids for watering pumpkins in hot weather come in handy.
How Does It Help With Watering Pumpkins in Hot Weather?
The ideal way to water pumpkins is to water the soil. Soaking the ground rather than the foliage gets essential moisture to the roots, where it is needed the most.
This can be done with a drip irrigation or a soaker hose, but these mean forking out for a new kit. However, you can put in an efficient watering system using materials most gardeners have lying around in abundance.
Digging a pot into the soil when planting pumpkins is an efficient way to direct the water to the roots. It doesn’t need to be a big pot; I have done it with a four or five-inch-wide plastic container. You can get suitable nursery pots at Amazon if you don't have any spare in your shed.
When you water plants, simply pour water into the pot to fill it up. The water will slowly soak out of the drainage holes into the soil (it might sound obvious, but make sure you use a pot with drainage holes) around the roots and efficiently hydrate the plant.
Delivering the water to the root zone is always better than watering from above. Wetting the foliage can lead to fungal diseases on pumpkins. This includes powdery mildew – a common issue that causes pumpkin leaves to turn white as fungal growth coats the top surface of foliage.
This pumpkin watering technique also works superbly for growing squash plants, which have shallow roots, too. That includes growing butternut squash, delicata squash, acorn squash, and other winter and summer squash.
As the season progresses, watering pumpkins can potentially get confusing, especially if you have a packed patch with lots of plants. A mass of vines and foliage can be disorientating. You know you need to water or fertilize the center of the plant, but how can you find it among all those sprawling vines?
That is where the simple task of marking each plant with a cane comes in super-handy. You can find the center of the plant easily, even when it grows lots of vines and foliage, and you know the perfect place to water and fertilize pumpkins. A simple marker also allows you to use a soil moisture meter in the perfect place to check the water levels in the root zone.
Just use a bamboo pole, wooden markers, metal plant stakes, or more decorative markers, depending on your preferred aesthetic or what you have to hand. Personally, I have only used a basic bamboo pole (you can get a range of bamboo stakes at Lowe's), but these decorative pumpkin stakes at Wayfair look attractive and can add a more personal touch to your plot.
To retain moisture in the soil and regulate soil temperature, mulching around pumpkins and squash plants after you put them into the kitchen garden is beneficial. Use organic types of mulch, such as compost, leaf mold, or bark chippings (such as this bag of pine bark mulch at Lowe's), and spread them in a layer 2-4 inches thick around the plant.
What to Shop
This liquid feed has an NPK ratio of 3-3.6-5.1 and contains minerals and seaweed. Mix the product with water and apply it when you water plants during the summer.
This collection has seed packets for growing four different types of pumpkins: Fairy Tale, Jack O Lantern, Small Sugar, and Casper.
This soil moisture meter helps you avoid watering issues with your pumpkins. Insert the probe into the ground near the center of the plant to see how wet the soil is.
Growing pumpkins can be simple, but there are always challenges along the road. You can spend time watering pumpkins in hot weather, feeding plants, and weeding the crop, but there remains the risk of pests that may trouble the crop.
A great form of natural pest control I recommend is companion planting. You can use the likes of chamomile, marjoram, catnip, and nasturtiums for companion planting with pumpkins. These flowers and herbs repel many typical pumpkin pests, as well as attract beneficial insects to naturally deal with them.
