Bringing indoor art and style outside

txaas_masthead

dog sculpture in gardenThe current trend to create “rooms” in our gardens is opening doors to incorporating more art into our landscapes. Garden design has taken on a new sophistication in recent years, evolving from the traditional whiskey barrel planters and gnomes of old.

Today, art is being used to bring color, texture and contrast into our outdoor rooms. From gazing globes and bottle trees to metal sculptures and pottery, art can add interest and depth to your landscape. How magical it can be when visitors to your garden discover a small sculpture or stepping stone slipped in among your flowers and foliage.  Or when you can draw them down a garden path to a beautiful gazing ball.

Now, the popularity of indoor decorating with items from nature also carries over and makes that possible in the garden. Home stores like Pier 1, World Market, Home Goods and other larger retailers are adding outdoor-themed decor to their shelves. Stone or ceramic irds, iron scrollwork and small statues have become staples, available for both indoor and outdoor use.  A variety of stores also offer all-weather paintings that can brighten up a fence or front porch. A few carefully-selected items and you can add a new twist to your garden rooms.

Gardeners are always looking for ways to extend the color in their landscapes as the seasons change. Colorful art in the garden can also add a pop of interest when plants lose their blooms or go dormant. A bright blue bottle tree will brighten up a brown winter landscape.

Bringing art into our landscapes is also another tool in the raging battle against the drought. Replacing grass or beds with hardscapes and art creates new focal points – focal points that don’t need to be watered.

How to find the right art for your garden, style and budget.

Sometimes finding the right accent for your garden is as simple as bringing your indoor decor outside. Perhaps you have some lovely metal lanterns or candleholders on your bookcase – a few more placed on your porch can create a cohesive feel.

Think about your personal style and think about traditionally-indoor home decor items for use outdoors if they are weatherproof or can be placed in a protected area. You may want to find a place for something that’s special to you, or you might want to find something for a special place in your garden.

Or do you want to place a little treasure in some secret spot in the garden to surprise visitors to the garden?

Be sure to choose an item or items that match the scale of your garden – a grand, life-sized sculpture might overpower a small cottage garden. Something too small could get lost, so think about the right balance for your space.

And, finally, art in the garden is intended to be the finishing touch.  Don’t overdo it – the objective is not clutter, but creating a sense of purpose. People should appreciate your garden, not your “stuff.”

Your choices should compliment your garden design and your personal style, and, most of all, make you happy.

November Tip: When winter arrives, there are many things you can do protect plants from frosts or freezes.

protect-plants-from-freezeIt is that time of year, when we play chicken with Mother Nature. Will it really get that cold? Am I in a little pocket that’s warmer/colder/somehow different than the forecast? Whenever winter arrives, there are many things you can do protect plants from frosts or freezes.

First, water moderately before the freeze. Water loses its heat more slowly than air throughout the night. Combined with covering plants or even a heat source, watering can help make a real difference by a few critical degrees.

Sheets, blankets and heavyweight row cover can all help protect plants. But it’s not the cover that keeps the plant warm, it’s the radiant heat coming up from the ground that is held in by the cover. Drape the cover all the way down to the ground and secure it like a tent with rocks, bricks or my favorite – canned vegetables (lighter than rocks, easier to find in a pinch, and they don’t mess up your sheets and blankets).

Do not, however, drape something over the top of the plant and tie it around the trunk like a giant lollipop. This is pointless, because you are actually keeping the heat away from the plant. If you have plants that can’t withstand the weight of a blanket or sheet, you can use tomato cages, boxes or PVC hoops or frames – really, anything to hold up the cover.

For particularly tender plants or a really cold night, you can also add a droplight or Christmas lights under the cover to create additional heat. Be careful not to let the bulb touch either plant or cover.

If temperatures rise above freezing – remove covers the next day to allow the plants to absorb the next day’s heat and recover as necessary.

So, plan now – collect your sheets and blankets, find some tomato cages, lights and canned goods and you’ll be ready to go when a surprise weather forecast sets you scurrying at 5 p.m.

Keeping tender plants under wraps protects them from freeze…

It is that time of year when we play chicken with Mother Nature.  Will it really get that cold?  Am I in a little pocket that’s warmer/colder/somehow different than the forecast?  Some of us are in perpetual denial, while the rest (like me) run around like Henny Penny thinking the sky is falling.
Depending on the source you check, the average first frost here in Austin is said to be anywhere between November 28 and December 5.  We didn’t follow the norm this year – with one of the earliest freezes for some areas last week.  Regardless of when winter arrives, there are many things you can do protect tender plants from frosts or freezes.
First, water moderately before the freeze.  Water loses its heat more slowly than air throughout the night.  Combined with covering plants or even a heat source, watering can help make a real difference by a few critical degrees.
Sheets, blankets and heavyweight row cover can all help protect plants from a freeze.  But it’s important to note that it’s not the cover that keeps the plant warm, it’s the radiant heat coming up from the ground that is held in by the cover.  Drape the cover all the way down to the ground and secure it like a tent with rocks, bricks or my favorite – canned vegetables (lighter than rocks, easier to find in a pinch, and they don’t mess up your sheets and blankets).
Do not, however, drape something over the top of the plant and then tie it around the trunk like a giant lollipop.  This is pointless, because you are actually keeping the heat away from the plant.  If you have plants that can’t withstand the weight of a blanket or sheet, you can plan ahead and use tomato cages, large boxes or PVC hoops or frames – really, anything to hold up the cover.
For particularly tender plants or a really cold night, you can also add a droplight or the large-bulb Christmas lights under the cover to create some additional heat.  Be careful not to let the bulb touch either plant or cover.
When temperatures rise above freezing – remove covers the next day to allow the plants to absorb the next day’s heat and recover as necessary.
Protecting container plants is a little trickier.  Their roots are much less insulated than plants in the ground and will get much colder.  To protect them, you can group them against your house and use the same techniques as you would for in-ground plants.  Even the littlest radiant heat from the house can help make a difference on a cold night.
Having spent years putting big pots of plants in the garage, this is also a great way to overwinter them, with a few conditions.  Remember, plants need light, and overhead light won’t cut it.  If you don’t have windows in your garage, make sure you open the garage door to let in sunlight and fresh air when temperatures allow.  In the garage, some plants will go dormant for the winter reserving their energy in their roots for the next spring.  Water them sparingly and let them rest for the winter. Once indoors, these plants require less water since there is no wind, and winter
daylight hours are shorter and lighting levels lower. When their leaves drop, don’t worry and don’t fertilize them to try to push them into growth while they are inside.
So, plan now – collect your sheets and blankets, find some tomato cages, lights and canned goods and you’ll be ready to go when a surprise weather forecast sets you scurrying in the dark at 6 p.m.

Early freeze means plants need TLC today…

Our first freeze here in Austin is usually the first week in December, so we are ahead of schedule today, with a freeze warning for the next two nights.

After a month of delicious rains, Austin gardeners are beaming with the resulting bursts of bloom and growth. 

But that’s about to come to a screeching halt if the weather forecasters are right.  The outlying areas of the Hill Country will certainly see a freeze, but Austin proper temps are usually a little warmer.  We’ll see.

Unlike most years, I got my plants into the greenhouse in time.

I’m still taking cuttings from tender plants throughout the garden, so space is filling in quickly.  I will admit that a few large pots/plants just didn’t make the cut this year so I could have room to walk into the greenhouse and to reach the ceiling windows in the back.

Many of the plants got a good clean up and a haircut.  A few of the plumerias that were towering over me were pruned to fit and the new stalks planted up in smaller pots.  After the heat of our dry and blistering summer, I get weary of potted plant care – every single day.  The cooler temps were invigorating and it was really fun to have my hands in the soil again.

The temperatures are dropping through the day today as the cold front hits.  I’ll turn the heater on late afternoon and keep them toasty warm through the night.

They look cozy in there together, don’t they? 

Now I just have to cover the peppers, pick the tomatoes and the basil, take more cuttings and water.

Guess I only thought I was ahead of the game!

Are you ready for winter?

October: Indispensable tools for easy gardening

There’s nothing worse than a dull pruner that leaves you twisting and yanking stems because it just won’t cut it. It’s frustrating, it’s time consuming, and frankly, it’s really bad for your plants.

Starting with a set of well maintained, essential tools can make your gardening a happier and healthier experience for both you and your plants. Check out our article, “The right tools make gardening easier” for a list of my personal favorites.

The right tools make gardening easier

Gardening is hard work. Digging, lugging and pulling can take their toll on you. But the right tools and techniques can transform a seemingly insurmountable job into a more manageable chore.

I used to buy garden tools wherever I could find them on sale, paying no attention to the brand or the style. With years of gardening trial and error behind me, I am a now a garden tool snob — with good reason.

Carry around a good soil knife to cut through clay soil.

There’s nothing worse than a dull pruner that leaves you twisting and yanking stems because it just won’t cut it. It’s frustrating, it’s time consuming, and frankly, it’s really bad for your plants.

After watching a television ad for a pruning saw a few years ago, a Black & Decker Cordless Alligator lopper found its way onto my Christmas list. Purported to make easy work of pruning with a mid-range rechargeable power tool, I was eager to try it. Imagine my horror when the blades started whirring and churning as it literally chewed through my shrub.

Tools do make a difference.

Start with good garden tools to make the work easier. These are some of Diana Kirby’s and including a child’s rake, … read more

IMG_1780These are some of the tools I wouldn’t garden without.

Soil knife. Great for cutting, digging in small spaces and trenching, I am never in the garden without my soil knife in hand. The sharp point and serrated edge make penetrating clay soil much easier work. It’s great for digging small holes. It can cut through weed barrier, remove small agave pups and little roots that might be in your way. If I were stuck on a deserted island, this would be my one garden tool. My soil knife is from www.gardenersedge.com.

Telescoping pruners. I’ve always had loppers — long-handled pruners for reaching in to trim shrubs or small trees. But my latest pair is expandable — with handles that unscrew and lengthen to reach just a little bit farther without having to get a ladder. At 5-foot-2-inches and with a fear of heights, anything that keeps me off of a ladder is a good thing.

Tomato cages. If you plant indeterminate tomatoes, you know they can grow up to be top-heavy monsters that can literally lay down a traditional round tomato cage. Then I discovered the extra-tall tomato towers by Gardener’s Supply Co. They are square, so they are sturdier than a 3-legged, cone-shaped cage. The extra tall ones can easily handle a vigorous grower, and they fold flat for storage — a real plus. They’ve recently added a new feature — coating the metal so they don’t rust. They are from www.gardenerssupply.com.

Rechargeable blower. Gardening is messy. You’ve got to have a broom, and a blower. I have three blowers. I started with the standard electric model, but the cord was always too short or in the way. So a few years later I bought the lightest-weight gas blower I could get. That was a mistake. Always messing with the pull cord and the primer and the fuel mix … ugh. The third one was just right. It has a little less power than the others, and the battery charge doesn’t last a long time, but it lasts long enough to clear off my front porch, sidewalk and really long driveway on one charge. It’s lightweight and easy to handle — so much that I gave one to my 83-pound mother-in-law, who loves it.

Bypass pruners. There are a lot of good pruners on the market — Fiskars and Dramm to name a few of the top brands — but I am a Felco girl. Yes, they are expensive, but they work. They handle well and have at least a dozen models that are specifically designed to fit your hand, no matter what size it is. They even have a full line of pruners for left-handers. With chronic tendonitis in both my arms, an easy-to-handle pruner that fits my hand makes a big difference.

Compact pruners. You need those curved bypass pruners, but you also need a pair of straight ones for deadheading and for cutting softer stems that tend to get bent in pruners for larger stalks. This little tool makes quick work of the snip, snip, snipping of spent blooms. There are many different brands of small and straight-edged pruners — my favorite pair is from Dramm.

Weeder. You can’t just pull weeds. Not in this kind of Central Texas soil. (Although our recent rains have made it easier, if only temporarily.) The clay and limestone we live with gets a death grip on weed roots and all your work will be for naught if you don’t take the time to pry a little of the root. My favorite tool for this is the CobraHead. Because of the way it’s made, the angle at which you use it is so much more comfortable for my hands and arms. Instead of holding a straight weeder with your thumb on top, pressing down and trying to pry upward, you can use the real power of your body to smack it down into the soil to pry loose the weeds.

Children’s tools. I have two different children’s garden tools on my rack in the garage — a hoe and a tiny rake. These are not well-made, but they often make working easier. The small hoe can come in handy in the vegetable garden where plants are often planted very close together. It’s also much lighter weight than a full-sized version. The rake is great for getting leaves out from between perennials and shrubs in garden beds.

Trowel. You might think a trowel is a trowel. Not so. When I first got my Fiskars “big grip transplanter,” I thought it was really heavy-duty and I didn’t know if I would really need that thing. That “thing” is great. Like the soil knife, its beveled, sharp, pointed end is perfect for slicing into unforgiving soil. And it’s big – it holds a lot of soil for a trowel and works well for digging a hole too large for the soil knife.

When I discover fabulous tools, I give them as gifts to my gardening family and friends. You can find the soil knife, tomato cages, pruners and blower at my parent’s house and my mother-in-law’s house. Other tools have found their way into friends’ Christmas stockings!

My motto: when you find something that really works, buy two.
