“My, what big eyes you have!” I say this nearly every time I encounter a Spicebush Swallowtail (Papilio troilus) caterpillar, like the ones shown below. Those aren’t eyes, though – that’s just what the caterpillar wants me to think. Instead, they’re a clever form of defense known as “eyespots”, and many caterpillars, butterflies, and moths use them.

Jill Staake Spicebush Swallowtail (Papilio troilus) caterpillars use eyespots for defense in the butterfly garden.

Eyespots are pigmented areas on an organism’s body designed to look like big eyes, in an attempt to fool predators into thinking a creature is much larger than it really is (Spicebush Swallowtail caterpillars are sometimes known as “snake caterpillars”). The actual eyes of those Spicebush Swallowtail caterpillars are about the size of a pinpoint, and are located lower down on the head, closer to the mouth. The eyespots are much bigger, and when the caterpillars are on a leaf of the same green shade as their bodies, the eyespots are the first thing a predator will see. With any luck, it will cause them to back off and seek a meal elsewhere.

Common Buckeye (Junonia coenia) butterflies are only a couple of inches across, but their eyespots can make them look much bigger to predators.

Adult caterpillars and moths use eyespots too, but they display them on their wings instead. Large eyespots can fool a predator into thinking they’ve disturbed a bird as large as an owl, rather than a small a relatively defenseless butterfly. Even if they don’t avoid the butterfly or moth entirely, the predator may be fooled into attacking a wing instead of the body, injuring the insect but still leaving it able to fly away and live another day.

Water is vital to a garden.  However, areas throughout the entire United States has been affected at one time or another with periods of drought.

Wouldn’t it be nice if your garden could weather dry periods with little impact to your plants?  It isn’t just possible, it is part of a movement toward more sustainable gardening, which includes strategies for conserving water while still having a beautiful, drought tolerant garden.

As a native Californian who now lives and gardens in the desert Southwest, periods of drought are not unknown and I have learned some helpful tips that have allowed me to enjoy a beautiful garden by following these helpful hints:

1. Water in the early morning.  Believe it or not, the time of day you water can make a difference in conserving water.  By watering in the cooler period of morning, there is less evaporation occurring.  Avoid watering in the afternoon, when much of the water can be lost to evaporation.  It is also wise to avoid watering in the evening when the moisture can foster fungal diseases.

2. Mulch around your plants.  Once you water plants, water begins to immediately evaporate from the soil’s surface.  By adding a layer of mulch, you help to limit the amount of water lost to the atmosphere.  In addition, mulching helps to keep the soil moister longer while keeping soil temperatures down in summer and warmer in winter.  Organic mulch such as shredded bark, leaf mulch and pine needles also adds nutrients to the soil over time.

3.  Use native plants when possible.  Wouldn’t it be nice to have a garden filled with plants that needed little to no supplemental water?  Native plants are specially adapted to survive on natural rainfall amounts.  In times of drought, they may need some supplemental water, but not as much as those that are not adapted to your local climate.  Another bonus is that native plants are generally more pest resistant, need little to no fertilizer and are lower-maintenance then those that aren’t native.  If you decide to plant some non-natives in your landscape, be sure that they are well-adapted to your climate without needing excess amounts of water.

4. Group plants with similar watering requirements together.  A drought tolerant garden will have higher water use plants grouped together toward the house where they can be watered easily.  Toward the outer areas of the landscape, more drought tolerant plants are planted next to each other.  For a list of drought tolerant plants, check out “40+ Drought Resistant Flowers and Plants”.

5. Use compost when adding new plants.  In the planting hole, mix 1 part compost to 1 part native soil.  The compost will help the soil to hold onto water for a longer length of time while not allowing it to become waterlogged.  Compost also adds nutrients to the soil.

Making your own compost is easy to do or you can purchase it at your local nursery.  Here is a great resource to get you started, “DIY Compost Bin”.

6. Allow grass to grow longer.  By letting your grass grow to a height of 3 inches, it will shade the roots thereby decreasing the amount of evaporation.  In addition, a higher mowing height will also help keep weeds from growing.

7. Decrease the amount of grass in your landscape.  A lawn uses a large amount of water – an average of 55 inches a year.  Beds filled with perennials will use much less water and provide a welcome spot of color in the landscape.  If you opt to take out your entire lawn, there are countless ways to create a beautiful garden that needs little to no supplemental water.  I recommend the book, “Lawn Gone” by Pam Penick, which is filled with landscapes that will inspire you along with guidelines on how to get rid of your lawn.

8. Use porous materials in your landscape such as gravel or sand-set step stones instead of concrete.  Rain water is able to seep through these porous materials, thereby watering nearby plants.

Drip irrigation

9. Install a ‘smart’ irrigation controller and/or drip irrigation system for plants that require supplemental water.  Wouldn’t it be nice if your landscape received supplemental water only when it needed it?  ’Smart’ irrigation controllers uses real time weather data and only waters your plants only when they need it, which can save 30 – 70% of water used for supplemental watering.  The Irrigation Association has more information about smart controllers and where to purchase one for your garden, which you can find here.

In addition to a ‘smart’ irrigation controller, a drip system is the most efficient way to get water to the root zone of plants right where they need it without wasting water.  Small drips of water permeate the soil without any water lost to runoff.  This is also the best way to water plants deeply, which is best for plant growth.  The roots of plants that have been watered deeply grow down deep into the soil where it is moister and cooler.  Hand-watering can be inefficient because water can runoff before it can penetrate the soil deeply.  If you don’t have a drip-irrigation system, you can water individual plants via drip by creating your own drip irrigation system using an empty milk jug.

10. Harvest rainwater.  When rain does fall, it is important to harvest and direct it toward our garden instead of allowing it to runoff.  There are a variety of ways to harvest rainwater including creating rain gardens and using cisterns or rain barrels.  On Friday, we will look at different methods for harvesting rainwater for our gardens.

Question: How do you save water in the garden?

Not long ago, I bought a cool little gadget that allows you to turn a plastic soda bottle into a DIY bird feeder, with the intention of doing this project with my nephews when I visit them next month. In the meantime, though, I discovered that this adapter can also be used on glass bottles, and decided to try a project for myself instead! This DIY bird feeder is made by wrapping twine around a glass bottle, held in place with double-stick tape. Here’s how I did it.

Twine-Wrapped Bottle DIY Bird Feeder Supplies

• Soda Bottle Feeder adapter (shown below)
• Glass bottle (be sure your bottle fits the adapter)
• Jute twine (I got 3 rolls for $1 at the dollar store) in color(s) of your choice
• Double-stick tape
• Metal corner bracket (found at your local hardware store)
• Superglue, scissors

Twine-Wrapped Bottle DIY Bird Feeder Directions

• Wrap a few inches of the bottle with double-stick tape. I found it easiest to work one section at a time, rather than wrapping the whole bottle at once. I used a very wide double-stick tape to make the process a little faster.

• Begin wrapping twine. Tuck the end underneath the first few rows as you work for a neater appearance. Keep each row of twine very close to the next, pushing it firmly into place as you go.

• Continue wrapping. Change colors as desired, wrapping the end of the old color beneath the new color as you work.
• Wrap until you’ve covered as much of the bottle as desired. Be sure to cover all visible tape. Use a dot of superglue to hold the final bit of twine in place.
• Glue the metal bracket to the bottom of the bottle and add twine to hang. (See this project for more info.)
• Fill your DIY bird feeder, add the bottom feeder piece, and hang!

One note: I haven’t tried this feeder out in very rainy conditions yet – I wouldn’t be surprised to find that it doesn’t hold up to intense rain very well. Still, it was fun to create, and cost only a few dollars. It will be great for the drier winter months here in Florida, and I can always bring it in if it we have lots of wet weather in the forecast.
