Climate Change and Gardening

by Stephanie Suesan Smith on December 3, 2017

Climate change can make gardening frustrating.  Techniques that you have followed for years no longer work.  Favorite plants die.  Rainfall has changed and you are either in a drought or a monsoon.  What can you do to cope?

You can continue gardening.  You just need to make some changes.  First, you may cautiously expand your plant selections to plants from the next warmest zone.  Plants that the growing season was too short for may now change.  Others that always froze out may now grow.  Some of your regular vegetables and ornamentals may be able to adapt to the warmer weather and you can still grow them.

Late freezes cause trouble.  You may find that late freezes kill many of your plants.  In North Central Texas this year, we have not had a hard freeze.  It is close to 80 degrees F as I write this.  Many plants are flowering out.  Many others never went dormant.  This not only means the grass still has to be cut often, it means if there is a freeze in January or February, our really cold months, flowers will be frozen and plants that are not dormant may die.

No cold, no fruit.  Some plants, such as fruit trees, need a certain number of hours of cold, called chilling hours.  If the plants do not get the chilling hours they need, they do not bloom.  No blooms means no fruit.  Some of our fruits will become increasingly hard to grow.  Orchards will have to move north to continue to produce.

Pests may thrive. Foreign plants and animals that are adapted to the new weather conditions may move in and thrive.  Problems such as fire ants, that have been kept in check by cold winters, may now spread to new places because of the lack of sufficient cold.  Finally, predators and prey may get out of sink with because of the new weather conditions.  This could allow pests to grow in number because of a lack of predators.  Even good animals can become pests if they have no prey (look at deer and gardens.)

Heat stress.   Plants that could formerly grow in your area may face a new foe.  The summer heat may come early and be more intense.  This means onions and cole crops such as cabbage and broccoli will bolt early.  They may bolt so early they do not make a crop some years.  Other plants may wilt in the extreme heat of summer.  Perennials that are unable to take the heat may have to be treated as annuals and be replaced each fall so they bloom in the spring before dying in the summer.

Drought.  You may have to choose carefully when planting because of limited water.  In some areas, outdoor watering bans caused lawns to die.  In others, you could only water certain days of the week between the hours of ten and six.  It may be necessary to plant slower growing, drought resistant plants, including vegetables.

Floods.  An intense rain event is calculated by the National Weather Service as one that brings more than two inches of rain in forty-eight hours.  These events are increasingly the way people get rain in many parts of the country.  This leads to root rot problems and can kill many plants that do not tolerate wet feet well.  This is especially problematic when you have drought interspersed with heavy rains.  The plants that do well during the drought generally do not do well with lots of water.

How to cope.  You can cope with these changes, although you may have to give up some old favorites among your plants.

  • Use plants from the next warmer zone.
  • Move up plant dates to take advantage of longer growing seasons.
  • Use longer spring temperatures to grow cool weather crops before it gets too hot for them.
  • Stay in touch with your Extension agent to find out about new pests and ways of dealing with them.
  • Use raised beds to prevent “wet feet” during prolonged rain events.
  • Plant frost resistant perennials so a late frost won’t kill them.

Gardening is great exercise, a way to improve your space, and a way to save on grocery bills.  All of these things are still possible.  Just make some adjustments to account for climate change.

Join in the Big Bug Hunt to Beat Garden Pests

by Stephanie Suesan Smith on March 19, 2017

BigBugHunt logo

How much would you give to know when bugs and other garden pests were coming so you could take preventive measures?  The Big Bug Hunt is asking for your help to develop an app that does just that.  Since gardeners are the ones who generally find new bugs first, the Big Bug Hunt is asking for your help.  They need you to report every bug you see in your garden.

What is the Big Bug Hunt?

  • The Big Bug Hunt is an international research project to track when and how garden bugs spread.
  • Participants are helping to create a pest-alert system that will warn gardeners when pests are heading their way.
  • Anyone can take part and reporting a bug takes seconds.  The more reports received, the quicker the pest-alert system can be developed.
  • Now, in its second year, The Big Bub Hunt has already identified patterns in the way some major pests spread.  Additional reports will improve accuracy and speed development of the pest-alert system

BigBugHunt.com is the website where you can report any bug sighting.  An app that you can use on your phone to report bugs is coming.  Any type of insect can be reported, from beneficial insects such as bees to insects such as aphids which are damaging plants.  Once you report a bug, the report is entered into a computer and analyzed to see patterns in how bugs spread.  Gardeners in the path of the bugs are then sent an email warning them the bugs are coming.

Knowing the bugs are headed their way, organic gardeners can use preventive measures to head off the coming invasion.  More conventional farmers and gardeners can also take preventative measures to protect their crops.  Reporting when the bugs appear will help scientists to develop more accurate predictive data.  This will allow gardeners in the path of the swarm to take measures to protect their crops, such as putting up hoops over their plants.

These bug alerts will be more and more valuable in pinpointing where pests are headed as the number of bug reports increases.  Growing Interactive is working with world class universities to design the app.  Of course, for the app to work properly, it needs data from gardeners on the ground.  That includes you.  Take a minute out of your busy day to enter the bugs you have seen in the BigBugHunt.com database.  You will be helping improve the app and will be more likely to benefit from it.  If you need help identifying the bug, the website has detailed pest identification guides that will help you identify the bug.  It even has effective treatment and prevention ideas for the bug you found.

Once you go to BigBugHunt.com, you can sign up for updates, bug-busting emails, and free downloadable charts.  You do not have to sign up for anything to register a bug sighting.  In fact, you can send the report while remaining completely anonymous.  It just takes a minute to report a bug, so do so with every bug you come across at BigBugHunt.com.  Thank you for your help.
