Hot Water And Plant Growth: Effects Of Pouring Hot Water On Plants

Garden lore is full of interesting methods of treating and preventing diseases that no sane gardener would actually try at home. Even though treating plants with hot water sounds like it should be one of those crazy home remedies, it can actually be very effective when applied properly.

Hot Water and Plant Growth

You’ve probably heard a lot of really unusual home remedies for pests and plant diseases (I know I have!), but using hot water on plants is actually something that works quite effectively on certain pests and pathogens. Unlike various pesticides or home remedies, hot water baths for plants can be quite safe for the plant, environment and gardener alike, provided you’re careful how you apply the water.

Before we get started in all this hocus-pocus, it’s important to note the hot water effects on plant growth. When you add water that’s too hot to plants, you’ll end up killing them – there’s no two ways about it. The same boiling water that cooks your carrots in the kitchen will also cook your carrots in the garden, and there’s nothing magical about moving them outdoors that changes this.

So, with this in mind, using boiling water to kill and control weeds and unwanted plants can be very effective. Use boiling water to kill the weeds in sidewalk cracks, between pavers and even in the garden. As long as you keep the boiling water from touching your desirable plants, it makes a wonderful, organic way to control weeds.

Some plants are more tolerant to hot water than others, but trust me on this: before you attempt to heat treat your plants, get a very accurate probe thermometer to ensure you know the water temperature that you’re dumping on your plants.

How to Heat Treat with Water

Heat-treating plants is an age-old way of dealing with a variety of soil-borne pests, including aphids, scale, mealybugs and mites. In addition, many bacterial and fungal pathogens are destroyed within seeds left in water heated to the same temperatures required for killing pests. That magic temperature is just about 120 F. (48 C.), or 122 F. (50 C.) for seed disinfecting.

Now, you can’t just go around pouring hot water on plants willy-nilly. Many plants can’t tolerate hot water on their leaves and above ground parts, so always be careful to apply the water directly to the root zone. In the case of insect pests, it’s usually better to submerge the entire pot in another pot full of water in that 120 F. (50 C.) range and hold it there for five to 20 minutes, or until your probe thermometer says the inside of the root ball has reached 115 F. (46 C.).

As long as you don’t overheat the roots of your plant and protect the leaves and crown from the heat, watering with hot water will have no harmful effects. In fact, it’s better to water with hot water than it is to water with very cold water. But generally, you should use water that’s room temperature so you protect both your plant and its delicate tissues from scalding.

How to Water Plants in Winter

Plants don’t need as much care in winter as they do in summer, but it’s important not to neglect watering your plants over the winter. Some ice or wind damage is unavoidable, but a lot of cold weather damage to plants’ cells is caused by dehydration. In many regions, normal winter precipitation is enough for plants because their cold weather watering needs are considerably less. However, making sure your plants have adequate hydration is the best way to protect them harsh weather.

Water your garden thoroughly in the fall, and deeply water newly planted saplings and shrubs. Plan to give the garden a deep watering every two to three weeks until the first frost.

Mulch your garden with leaves and compost in the fall after pulling spent annuals and cutting back perennials. Mulch protects your topsoil and helps it retain water. It also nourishes roots and keeps them warm. Spread at least an inch of mulch over the ground. Pile up some extra mulch around any new saplings or plants that have been planted within the last year.

Prepare for sudden fall frosts by checking your local weather report. Watering your plants before a frost will protect them from damage caused by freezing. The roots need a chance to absorb the water before it freezes, so try to soak them at least 24 hours before the frost.

Avoid getting water on the plants’ stems and leaves when you water in the winter. Ice sitting on foliage can kill it or cause it to break off. Water woody plants like shrubs and saplings away from the trunk because ice can damage the bark.

Water plants during the winter only after long dry spells of two weeks or more. Plants are inactive during the winter so they don’t need much water, but if the soil completely dries out they risk damage from wind and dehydration.

Water your garden even when the ground is frozen during a long winter dry spell. Watering helps aerate the soil and warm the roots, and plants can’t get enough moisture from the soil when it’s frozen. Do the watering mid-day to give the plants a chance to absorb the moisture before night temperatures freeze the water.

Watch sunny parts of your garden for shallow-rooted plants that have heaved, or raised out of the soil due to repeated freezing and thawing. If you see a plant has heaved, push it back into the soil as soon as possible and give it some extra mulch to keep it shaded and prevent the soil from thawing.

Winter Watering Tips for Your Garden

It’s Freezin’ Season (and your Landscape is Thirsty!)
Winter has arrived in full force. And while your landscape has entered a state of dormancy, it still gets parched every now and then. Let’s discuss how to keep your plants alive in winter with some winter watering tips. (Hint: Watering is mandatory!)

Simple Tips for Gardening in Cold Weather
Despite the fact your plants are dormant and brown, they should still be watered periodically. Plants that remain dehydrated in winter months often don’t survive until spring. Not only does this create extra landscaping costs in warmer months, it can actually damage your plumbing. How so? Plants that receive insufficient winter hydration search for water on their own. The most frequent target? Your wastewater pipes. Roots will attempt to penetrate underground pipes, causing messy, costly repairs.

Creating Watering Schedules for Winter Gardening

  • Choose a warm day with air temperature above 40 degrees Fahrenheit.
  • Ensure that the soil is unfrozen.
  • Try watering at mid-day — when temperatures are higher—so it can soak in before it freezes at night.
  • Water your landscape once or twice per month from November to April.
  • New roots form in the months of March and April. It is most critical to water during these months.

What to Water When You’re Gardening in Cold Weather

  • Newly planted lawns, trees, shrubs and flowers require the most attention in winter gardening.
  • Established turf and trees, especially those in sunny, windy, or exposed areas should be a high priority. Watering prevents them from drying out due to unique environmental conditions.
  • Established shrubs, flowers, ornamental grasses and groundcovers will also benefit.
  • Do not water cacti, succulents, or buffalo grass.

More Tips for Winter Watering

  • To prevent freeze damage, most automatic sprinkler systems are turned off during the winter. To combat this inconvenience, use a hose-end sprinkler or watering wand.
  • Remove the hose from the spigot after watering. Leaving the hose attached can cause water to freeze in your pipes, causing expensive damage.
  • Water for short periods, allowing it to soak in before re-applying.
  • Ensure that the ground doesn’t stay soggy for long periods after watering. This may cause root rot, killing your precious plants.
  • To determine how long to water, place cups in your yard to catch some of the water. Water until you can measure 0.5 to 1” deep in the cups. Once you reach this threshold, you’ll know how long to water in future sessions.

Don’t Neglect These Tips for Winter Watering!
When it comes to having a lush landscape in spring, the importance of winter watering can’t be overstated. Follow these tips for gardening in cold weather, and your garden will show its gratitude when warm weather rolls around.

Does Boiling Water Kill Weeds?

Today we’re going to show you another way of killing weeds. We’re going to boil them. The theory here is that we are not only going to kill the plants above the ground but that the water and the heats can transfer down and kill the roots as well.

Boiling water is certainly an appealing alternative to toxic herbicides: it’s free of harmful chemicals, it’s cheap, and it kills weeds. Yet, piping-hot water isn’t the best weed killer in every situation, because the super-hot liquid kills not only weeds, but also any vegetation surrounding it.

Even if you cover your other plants with a plastic cup to shield them from the scalding water, you can’t protect them underground. For this reason, reserve the boiling water for weeds growing out of cracks in the pavement or driveway, far from desirable plants.

Things You’ll Need

  • Kettle
  • Water

Step By Step To Kill Weeds From Boiling Water

Step 1: Surveying

Survey your sidewalk and driveway to identify the weeds you can cook without running the risk of killing other plants.

Step 2: Boiling

Boil water in a kettle with a narrow spout so when you pour your hot water on the weeds, it doesn’t splash on anything else.

Step 3: Pouring

Pour boiling water to cover the weed and to penetrate the ground to the plant’s root zone.

One reason I really like boiling water to kill the weeds is that there’s no chemicals that you can actually drink. Water it’s so safe and cheap so that you can have another free and easy way to deal with weeds problems.

We Plant and Water, God Causes the Growth

As I have written about previously the house that we live in had something going on unknown to us. For years and years tree roots were growing under the ground, growing ever closer to the outgoing sewer pipe of our house. No one living in this house over the years knew what was taking place, it was all incognito. But then that fateful Saturday came when the water would not go down and the sewer started to come back. With some investigation it became clear that roots had grown into the pipes and the pipe had to be replaced to restore service. Last time I pointed out that this biblically illustrates the eventual result of not resisting temptation.

This time, however, I would like to use this experience as a very positive illustration of biblical truth that this whole experience has revealed. A few weeks ago I (and three of my children) started working on planting new grass where the pipe had been replaced. First we filled some dirt in where there had been settlement. Second, we leveled out the dirt and picked out the many rocks on the surface. Seed was then planted, fertilizer was applied, and straw was spread over the newly planted seed. When we completed all that work there was no grass-not even one fresh blade. For the next two weeks I daily watered the area or it rained. For two weeks it looked like nothing was going on. But then I heard the good news, my wife told me that she had leaned down closely to the ground and saw tiny shoots coming up. We were elated, but for the last few days before the first blades were spotted I have to honestly say I was starting to wonder if there would be any grass.

Just like our previous grass looked fine and yet there was a problem brewing below the surface, so with this newly planted grass there were things taking place below the surface that I could not see or appreciate until the blades showed up. Consider a parallel image that Paul uses in his letter to the church at Corinth:

I planted, Apollos watered, but God was causing the growth. So then neither the one who plants nor the one who waters is anything, but God who causes the growth. (1 Corinthians 3:6-7).

Paul was dealing with a church that had become focused on who it was that was ministering rather than on the fact that it is God that brings about spiritual fruit. But in so doing He reminds us that we plant and water but God causes the growth.

If you are a child of God through faith in Jesus Christ then you have been called to spread the message of Jesus Christ to all those around you. One of the main reasons that born again Christians can become discouraged in this privilege of spreading the seed of the gospel is the lack of response. I want to encourage you though with this principle of planting, watering and growth. You may be faithfully planting the seed of the gospel in the lives of your children, your spouse, extended family, friends, co-workers etc. and the results may look just as our yard did after 10 days. In fact, not only did our yard look barren and dirty, it actually looked worse than it did right after we planted the seed because some of the straw had blown away. And yet, under the surface the soon growth was on its way. Things were happening below the surface that could not be seen by the naked eye.

We often concern ourselves with whether or not “the grass is going to grow” rather than being focused on doing what God has called us to do. We need to think through some implications of this truth.

1. We are not responsible to cause spiritual growth in the lives of those we minister the Word of God to. If we think we are we will go about spiritual ministry in an unspiritual way trying to force something that only God can do.

2. We do not see all that God is doing below the surface of someone’s life as we minster God’s truth to them. If we assume that we see all that is going on we will get discouraged and become hopeless in spiritual ministry. But if we recognize that God is the one that brings growth and He is at work even below the surface we can keep watering that seed in faith.

3. We must not doubt the potency of the Word that we scatter in spiritual ministry. If we are shaken in our estimation of the seed of God’s word we will turn to other means to try to bring about spiritual growth rather than the regular watering means that God has given (E.g. the Word, Prayer).

4. We must not define success in spiritual ministry as spiritual growth but faithfulness in our responsibilities. If we are called to plant and water and only God can give the growth then we must focus on the planting and watering and believe that in God’s good time the seed of the gospel will bear fruit.

5. We must never presume upon God’s sovereign grace in spiritual ministry through neglecting His means of planting and watering. Yes God sovereignly causes spiritual growth, but He sovereignly does so through the means of the gospel spread, the Word communicated and the petitioning for spiritual growth.

6. We must patiently plant and water knowing that all growth takes time and God is sovereign over the timetable of spiritual growth as we plant and water the truth.

We can be sure of this. If we are faithful at planting and watering God’s Word in God’s time and in God’s way it will bear fruit. Do not assume you know all that is taking place under the surface. It might just be that you are two days away from seeing some blades of grass, two weeks away from having to mow grass, and months away from having a yard full of think grass. Spiritually, if you do have a yard full of grass in the future, it will not be because you planted and watered (though you must do that!), it will be because God in His grace caused growth through your planting and watering. Be encouraged, plant and water believing in the God who causes growth, even if you cannot see that growth as quickly as you might desire.

Top 10 best-ever tips for watering your garden in summer

To prevent your plants from hanging their heads in summer they need plenty of water. But how much or how often should they be watered? And is it better to water from above or below? Continue reading and you will find some smart and helpful facts for watering your plants.

1. Keep evenly moist

Most plants depend on even moisture. Slight drying out, however, before watering can promote root growth in plants.

2. Water more seldom but then thoroughly

In the flower bed, one to two watering sessions per week is usually sufficient. It is better to water occasionally but with plenty of water rather than a little water often.

3. Water late in the evening or early in the morning

When you water cool soil in the evening less water evaporates than when watering hot soil during the day. Watering of an evening or early morning also allows plants to sufficiently supply themselves with water before the next day’s heat.

4. Keep leaves dry

Wet leaves can become diseased leaves. Kept wet overnight, leaf-mould may result. Leaves that are wet in the sun can develop slight burn marks (burning glass effect of the water droplets).

5. Give the right water quantity

Requirement-suited watering means that the water must sufficiently reach the roots. Too little water will only cover the upper soil centimetres or may not even reach them at all ( e.g. when there is mulch covering the soil).

6. Give larger water quantities in parts

Water needs a moment to seep into the soil. To prevent precious water in the bed flowing away unused it’s better to water repeatedly in sections.

7. Water with a target but distribute

Always watering at one root point only leads to onesided root growth and thereby to poorer nutrient absorption from the soil. Therefore, always water around the plant and covering the entire irrigation area.

8. Irrigate in a way that saves water

Water as much as necessary and as little as possible. This can be simplified with an automatic irrigation system with moisture sensor located in the garden bed, on the balcony and on the lawn.

9. Avoid waterlogging

Waterlogging suppresses the breathing air of the roots out of the soil and the root cells drown without oxygen.

10. Use quality, clay-rich soil

Plant soil rich in clay minerals has better expanding properties and can therefore hold water in the soil much better and in a more even way. In wet summers and in winter ensure adequate water drainage to prevent waterlogging.
