How Rainy Days Help Fertilize Plants

The rain actually fertilizes your plants.

Do you like rainy days?

Chances are, if you live in the desert Southwest, you rejoice when the clouds roll in, and the rain begins to fall.

After the rain stops, have you ever noticed that plants look fresher and have a brighter shade of green?

If so, it’s not your imagination. The rain actually fertilizes your plants.

Take a moment and think back to your days in high school when you learned that the Earth’s atmosphere is made up of oxygen and nitrogen.

When rain falls, it brings some of the nitrogen down from the atmosphere straight to plants. This form of nitrogen is easily absorbed by plants and fertilizes them as well as the soil.

How cool is that?

So the next time you enjoy a rainy day, it’s nice to know that your plants do too!

Reading The Leaves: Diagnosing Common Plant Ailments

Did you know that you can often tell what is wrong with a plant by looking at its leaves?

It’s true.

Diagnosing Common Plant Ailments

‘Reading the leaves’ to diagnose common plant ailments isn’t hard to do if you know what symptoms to look for.

Problems such as iron or nitrogen deficiency are fairly easy to identify as is salt and sunburn damage.

A Summer Edible Garden: Part 2

,

I hope you enjoyed the grand tour of my edible garden that I created in my side yard.

Today, I would like to show what is happening in my original vegetable garden…

my edible garden

As you can see, there is a lot growing in this area.

Among the vegetables is a giant sunflower, pots filled with ornamental plants AND vegetables and hollyhocks that have finished flowering can be seen alongside the garden.

Off to the right side, you can see my container corn.

And yes, those are plastic patio chairs inside my vegetable garden.  (I’ll explain why later.)

This edible garden is actually made up of three parts.  My original vegetable garden was a fenced in square space.  Like many gardeners who like to grow their own food, I realized that I needed more space – so we added on an extension a couple of years ago…

The third part of my edible garden consists of vegetables growing in containers along with ornamental plants…

I currently have zucchini growing in the closest pot along with a jalapeño plant, parsley and sweet potato vines.

The middle pot is filled with a Thai pepper plant, chives, cucumber, celosia and kangaroo paw.

The third (and my most favorite container) has a bell pepper plant, cinnamon basil, green & purple sweet potato vines, dianthus and angelita daisy growing inside.

The outer vegetable garden is filled with sunflowers and bush beans.

Our family loves to eat ‘string beans’.  They are easy to grow and to freeze for later.

Here is something that you may not know about growing beans.  “They make their own nitrogen, so you don’t need to add any nitrogen fertilizer.”

In fact, if fertilize them with a fertilizer that contains nitrogen – it can cause them to grow beautiful leaves, but not beans.  That is because there needs to be a balance between the other major nutrients – phosphorus and potassium.

If you do apply a fertilizer, make sure that contains a low amount of nitrogen.

I have lots of cucumbers growing in the original vegetable garden along with a couple of pumpkin plants.

As a child, I grew up calling cucumbers ‘gurkens’, which is what they are called in German.  I spent some time when I was young, in Germany, visiting my grandparents while my grandfather was working over there.

I love cucumbers and we eat them 3 or 4 times a week.

It can be a little hard to spot ripe cucumbers.  Most of my cucumber plants are growing up onto the trellis, but sometimes you can find cucumbers growing on the ground.  You need to move the leaves aside to see them.

I like to eat cucumbers with salad, using my grandmother’s ‘top secret’ salad dressing recipe.

I only wish that I could grow cucumbers and leaf lettuce at the same time….

Okay, back to the patio chairs sitting in my garden.

Why on earth would I place chairs in my garden?

Well, they are an easy way to provide shade for vegetables that quickly wilt in the full sun.

And so, that is what is going on in my edible gardens this summer.

**I am excited to share with you a gardening video that I made for Troybilt as a part of my involvement with the ‘Saturday 6″.

I’ll debut it for you on Monday 🙂

Fall Citrus Tree Care

, ,
Citrus trees

In the Desert Southwest, we are fortunate to be able to grow citrus.  In early fall, your citrus tree probably looks like the one pictured, with green fruit that is getting ready to ripen in this winter.

It is time for the third fertilizer application to your citrus trees if you have not already done so.  Mature citrus trees require three applications of fertilizer – around Valentine’s Day, Memorial Day and Labor Day.

Citrus trees require nitrogen more than any other nutrient.  I recommend using a granular fertilizer specially formulated for citrus because, in addition to nitrogen, they also contain micronutrients, (iron, zinc, manganese), that are vital to the health of your citrus tree.  Citrus fertilizer spikes are also an option.

If you choose to use only organic fertilizer for your citrus, there are some natural products available, or you can use composted cow manure, working it into the top few inches of soil and watering it in afterward.

GENERAL GUIDELINES:

– Fertilizer should not be applied to newly planted trees – wait until they have been in the ground for one year.

– Water the soil around the tree before and after you apply fertilizer.

– Follow the directions on the fertilizer bag.  Be sure that you divide by three the annual amount of fertilizer needed by your tree – do not apply all at once!

– When in doubt, apply slightly less fertilizer then you think you need.  You don’t want to over-fertilize and end up with fertilizer burn.  Smaller trees require less fertilizer than larger trees.

– Apply granular fertilizer around the perimeter of the tree, extending just past the drip line.  Work into the top few inches of soil.

– Do not apply a foliar fertilizer when air temperatures are 85 degrees F or above because there is a danger of burning the foliage.

– For mature Grapefruit trees, (over six years old), apply only 1/2 the amount of fertilizer recommended on the fertilizer label because high amounts of nitrogen promote a thick rind (peel).

Get ready to enjoy the fruits of your labors this winter and get ready for March when we will discuss the correct way to prune and plant citrus.
