Prepping for a Deep Freeze…

, , , ,

 It’s about to get really cold…

Desert Southwest

Well, cold in this area of the desert southwest.  Temperatures are predicted to dip into the 20s for a few days, which is quite cold for zone 9a.

As a result, I am being asked by quite a few people about what they should do to prepare their semi-tropical plants for the cold temperatures.

The best thing you can do is to cover your frost-tender plants.  This helps to trap the heat that rises from the ground, which raises the temperature by a few degrees around your plants.

Earlier this week, I wrote about how to protect your plants during a normal winter freeze (30 degrees and above).  You do have the choice to protect your plants or not.  I mentioned that I only protect my high-profile Lantana near my front entry.

But, when temperatures are forecast to fall into the 20s for a few days, I start pulling out all my old linens, including my kid’s old character bed sheets…

semi-tropical plants

I cover most of my semi-tropical plants, including my other lantana, young citrus tree, yellow bells, bougainvillea and pink trumpet vine.

The reason for this is that I don’t want my plants killed to the ground by the frost, which can happen when temperatures dip into the 20s for a few days.

You see, frost damage can be cumulative with each additional night of freezing temps, creating more damage to plants.

So, if you have frost cloth – use it.  If you don’t, then start raiding your linen closet and pull out towels, sheets, tablecloths, etc.  Believe it or not, even newspapers can provide some protection.  Just anchor it down with rocks to keep it from blowing away.  (I once used canned foods from my pantry to anchor frost blankets 😉

What you shouldn’t use is plastic.

Also, if you want to protect your plants – you have to do better than this person did…

What they ended up with was plants with green areas, surrounded by brown, crispy frost-damaged growth.  You need to cover the entire plant with no gaps.

Watering your plants at dusk also helps because water releases heat into the night.

If you have columnar cacti, then protect the ends using styrofoam cups.

Young citrus trees should also be protected.

If freezing temperatures persist, you can keep the coverings such as towels, sheets, and blankets on your plants for at least a week. If freezing temperatures last longer, uncover plants for a few hours during the middle of the day when temps are over 45 degrees to allow them to get needed sunlight. *If you use frost cloth, it is permeable and doesn’t need to be removed.

So what do you do if you don’t protect your plants and they look like this afterward?

semi-tropical plants

Relax, first of all.  More than likely, it is still alive at the base and will grow back once spring arrives.

Whatever you do, DON’T prune them now!  That can damage or even kill your plant.  I know it is ugly, but it is only until spring when you can prune all the frost-damaged foliage away.

**Even if you protect your plants from frost, there can still be some frost damage that occurs.  It all depends on the severity and duration of the cold.  But covering them increases the chance that they will recover once temperatures warm up in spring.

Got Heat-Stressed Plants?

, , , , , , , , , , , , ,

Do you enjoy the summer heat?

I’m going record to state that I’m not a huge fan. I prefer to endure the intense heat indoors in the comfort of air-conditioning.

However, the plants in my garden don’t have that option. They are stuck outside no matter how hot it gets.

I always feel sad when I see plants struggle in the heat of summer. If I could bring them indoors to cool off I would 😉. But, let’s face it, that isn’t realistic or really what is best for plants.

For that reason, you will find the plants around my home are fairly heat-tolerant.

If you think that heat-proof plants are boring (and if I’m being honest, some are), many are attractive and beautiful.

One of my clients has a great example of an eye-catching entry that is fuss-free and shrugs off the heat of summer.

Artichoke agave (Agave parryi v. truncata), golden barrel cacti (Echinocactus grusonii), and lady’s slipper (Euphorbia lomelii), and yucca create a living sculptural landscape with their unique shapes.

As you can see, you don’t have to settle for a blah garden or one filled with heat-stressed plants. In fact, I loved this example so much that I featured it in my book, “Dry Climate Gardening” which is available for pre-order.

You know that I don’t care for fussy plants – I prefer plants that look great with little effort on my part and this succulent garden is a great example, don’t you agree?

I invite you to take a walk through your garden to see what plants may be stressed from the heat. It may be time for you to switch them out for more heat-tolerant ones.

Tips to Save Money When Shopping for Succulents

I enjoy attending plant sales hosted by botanical gardens. Why? Because you can often find the newest plants (even hard to find ones) at them. Of course, you can also find old favorites as well.

Smart Succulent Shopping: Tips to Save on Succulents

Succulents, including cacti are a great way to add texture and interest to the garden at a fraction of the maintenance and water that other plants require. However, they tend to be more expensive than shrubs, vines, and perennials. But, don’t worry – I’m here to help you save money on succulents with these tips…

Shopping for Succulents

1. Choose Wisely: Avoid purchasing agave in 15-gallon containers or larger.

Why?  Well, almost all species of agave will flower toward the end of their life and then die.  That is what agave do.

Flowering is triggered by the age of the agave. In addition, different agave species live for differing lengths of time – some live less than 10 years. If you buy a 15-gallon or larger boxed agave – it is safe to assume that they are much older then those in smaller pots and will flower and die much sooner.

So my advice is to purchase agave in 1 or 5-gallon sizes – they will last much longer and you’ll save a lot of money.

*BONUS: Look for succulents that have more than one plant growing in the nursery pot. Sometimes, you can find more than one – that’s like getting 2 for the price of 1!

Better yet, ask a friend or neighbor for a volunteer (pup) from their agave.  Many agave species produce volunteers that can be transplanted.  To learn how, click here.

2. Size Matters – Buy smaller cacti rather then larger.

Columnar cacti are beautiful, but expensive. The price is usually based on the height of the cactus. Saguaro cacti are priced based on each foot high they are plus the height of each arm.

The price for a 1 ft. high Totem Pole cactus was $48.

The reason that I recommend starting out with a smaller columnar cactus such as Mexican Fence Post (Pachycereus marinatus) or ‘Monstrose’ Totem Pole (Lophocereus schottii ‘Monstrose’) is that they will begin to grow at a faster rate once planted in the ground.

Smaller Plants are Smarter Plants

In fact, smaller plants have an easier time becoming established then larger ones.

Many columnar types of cacti grow faster in the landscape then in the wild due to the presence of water – that includes saguaro cacti as well.

Cacti from Cuttings

Like agave, you can start some species of columnar cacti from cuttings.

I planted this Mexican Fence Post cactus in my garden 11 years ago.  It started out as a 2 foot cutting given to me by a client from their large cactus.

Look how much it has grown! You can ask a neighbor or friend if they would mind you taking a stem (or pad) off of their cactus so you can start your own.

Many cacti can be started as cuttings. Simply take a piece of cacti, and place it in a dry, shady spot for two weeks and then plant it in the ground or in a pot. Wait a month before watering. For a new cactus cutting, it’s a good idea to water it once a month through its first year.

3. Plant with Care: Handling Prickly Succulents

If you hadn’t noticed, many succulents are prickly. So, it is a good idea to plan on how you are going to plant it. Decide whether you can do it yourself or if you will need to hire someone to plant it for you.

For small cacti, you can use a towel to help you plant them without getting pricked. See how here.

For larger cacti, you can use pieces of carpet or rubber straps. But when in doubt about whether you can plant it yourself, hire an expert.  

Teddy Bear Cholla (Opuntia bigelovii)

*Years ago, as a golf course horticulturist, I used to transplant Teddy Bear Cholla (Opuntia bigelovii) from areas that were to be built upon.  I would use rubber straps to carry the cholla and regular kitchen tongs to pick up the pieces that dropped off.  I would then plant them elsewhere.

4. Look for Discounts: Keep an eye out for discounted plants.

Often, not all plants will meet the high standards of the nursery.  Sometimes, this can be mostly cosmetic damage, but occasionally you will see a succulent that has not been watered correctly or placed in too much or too little sun.

This can be a great way to save money and provide a little TLC to new succulents.  Research online how to care for that particular plant and soon you will have a healthy succulent growing in your garden that cost you a lot less.

I hope that these tips will be helpful to you the next time you are shopping for succulents.

Succulents: Great Alternative Container Plants

, , ,

Did you know that one of the great things about living in the Southwest is the fact that we aren’t limited to just growing flowering annuals in our pots – succulents make great alternative container plants!

Last year, I replaced all of my flowering plants with succulents and I haven’t looked back.  They look great and take very minimal care, which fits into my busy life perfectly.

Recently, I visited the Desert Botanical Garden in Phoenix and saw some great examples of potted succulents, which I thought I’d share with you…

As you can see, there are so many options when you decide to use succulents in containers.

Whether you live near the Desert Botanical Garden or even if you don’t – you can visit your local botanical garden for some alternative ideas for filling your containers.

Growing succulents in pot is easy – the most important thing is that they are well-drained, so it’s important to use a planting mix specially formulated for succulents.

Purple, Prickly and Gorgeous!

If anyone asks me what is on my list of succulent favorites, Santa-rita prickly pear would be near the top.

This beautiful prickly pear is also often referred to as ‘purple prickly pear’.

I love how the its gray/blue pads become gradually tinged with purple as the temperatures get cold.

Southwest Gardener’s May Checklist

September Gardening Tasks

, , , ,
summer is beginning

There are some signs that summer is beginning to fade and that fall is around the corner.  The stress that the high temperatures of summer bring has caused many plants to slow down their growth.  

However, the slightly lower temperatures in September bring on a flush of new growth for many trees, shrubs, and succulents in the garden.  I enjoy being out in my garden this time of year and seeing many of my plants rejuvenated.

With the somewhat cooler temperatures, I am now seeing many gardeners venturing outside and taking stock of the condition of their landscape.  Fall is a busy time in the desert garden because it is the ideal time to install many types of plants, which will be discussed in a separate post in early October.

SHRUBS: I just finished lightly pruning my ‘Rio Bravo’ sage (Leucophyllum langmaniae).  Summer flowering shrubs that are cold-hardy look their best when lightly pruned at this time to help reign in rangy, sprawling growth. This should be only done with hand pruners only.  Do not use a hedge trimmer and shear your shrubs.  They should have a pleasing natural shape when you are finished.  Do not prune back frost-sensitive plants at this time.

summer is beginning

ANNUALS:  Although the local nurseries are abundant with winter annuals, I don’t recommend planting them now.  The temperatures are still quite hot, and there is a good chance that they will not make it.  

In the past when mid-September came, I would load up the truck with 100+ flats of annuals to plant around the community where I worked as the horticulturist.   I would then spent the next four weeks making repeated trips to the nursery to replace dead plants that just could not handle the heat of early fall.  From then on I would wait until October to change out summer annuals and replace with winter annuals.  As a result, we suffered very little plant loss.

summer is beginning

TREES:  Mesquite and Palo Verde trees that are overgrown can be lightly easily pruned back.  Resist the temptation to heavily prune at this time.  January and February is the time for heavy pruning to occur for these trees.

summer is beginning

SUCCULENTS:  Cacti, agaves and other succulent plants do best when planted when soil temperatures are warm, which makes September a great time to install them before cooler temperatures arrive.   Prickly Pear cactus can be pruned back this month if needed.  Problems with agave may show up this time of year. 

summer is beginning

If your agave suddenly collapses, there is a good chance that they have gotten an infection with agave snout weevil.  There is no cure and the agave should be removed, it will be smelly due to the decay the weevil causes – and not just a little stinky.

One of my (least) favorite memories happened years ago when I worked as a horticulturist on a golf course.  One year, we had to remove countless agaves throughout the landscapes due to a large infestation – the smell was awful.  If this happens to your agave, do not plant another agave in the area – use another type of plant instead.

Roses

ROSES:  Roses should be lightly pruned and fertilized this month (see earlier post for details).

citrus trees

CITRUS:  Make sure to fertilize your citrus trees if you have not already done so (see earlier post for details).

NEXT MONTH – get ready for planting and wildflower garden preparation!
