Do you live in a desert clime and want togrow stellar tomatoes ? tomato can boom in desert climates and yield abundant crop . Desert tomato grower may even delight plants with less disease , fungus and rot due to the juiceless climate .
However , desert growers are up against difficult condition . Hot , dry Clarence Shepard Day Jr. that throw away down to very cold nights , low humidness and gusty winds , low urine availability , and heavy monsoon rainfall . So how can you hope to have a great proceeds this time of year , if you live in a desert mood ?
After ten years experience growing tomatoes andother veggies in the mellow desert of Arizonafor farmers markets , I ’ve picked up a few tips that can help you grow bully tomato in spicy , arid climate . This clause will focalize on tomatoes rise outside in filth orcontainers , not hydroponic or high tunnel - grown tomato .
Choose The Right Variety
place yourself up for anabundant tomato harvestby pick a miscellany that will mature well in a tough desert climate . Most tomato motley will farm in desert climates , but some will perform importantly better than others .
Whenchoosing seedsortransplants , foot ones that are lean as “ heat - resistant . ” Today ’s tomato plant breeders are making excellent progress in varieties that can stand up to tough conditions .
Many super - sturdy tomato plant varieties arehybrid ( F1 ) plantswhich combine the best traits of two parent plant . Hybrids have great disease resistance too . Hybrids seeds are not GMO seeds . The downsides of loanblend tomatoes are that the ejaculate will not “ come true ” to the tomato that you carry through them from . The seeds also run to be more expensive than open - pollinated seeds .
If you need to store your own tomato seed , choose an open - pollinated or heirloom change . Red , pinkish , orange and yellow fruits fare better in the hot sun thandark - fruited varieties , which take in more heat and aremore prone to sunscald .
If you are only growing one tomato plant , you may have more succeeder with smaller fruit type such as cherry or “ saladettes . ” These types run to produce more abundant , uniform crops than larger fruited “ self-aggrandising boy ” types in desert climates .
Consider Virus Resistant Varieties
Curly - top viruses ( CTV ) are afamily of pathogensthat touch on many cropsincluding beets , tomatoes , Alexander Melville Bell peppers , and cucurbits in desert regions . carry by the beet leafhopper insect as it migrates north in bound , some years are particularly forged than others .
The skilful affair a desert grower can do is choose CTV tolerant motley . In my years of grow tomato in Arizona , cherry tomatoestend to be less susceptible than heavy - fruit heirloom .
CTV symptomsshow as a wilty - looking works that fail to perk up even after lacrimation . The wilty spirit cave in way to a plant that may look stunted and twisted and fails to thrive , turning yellowand eventually browned . Unfortunately , there is no cure for CTV . The best course of action is to take out anddispose of mistrust CTV plantsimmediately .
If you are come out your industrial plant from seed you could take semen that are list as Curly Top Virus Resistant , or CTV tolerant . necessitate your local nursery what varieties they have and if they are immune to Curly Top Virus .
Know Your Last Frost Date
Part of the charm of the desert is the warm wintertime days . They can fool away a nurseryman into set out tender plants like tomatoes too too soon . However , desert wintertime night can plump tobelow freezing . This is especially true in high mountain elevations and at the buttocks of deep canyon .
Before set out tomatoes , know your average last frost appointment in the leap and watch the nighttime temperatures judiciously through spring and early summertime .
If the temperature even hovers above freezing , your specific microclimate ( see below ) may drop cold . Keep anold layer sheetor row cover handy in sheath freezing temperatures are predicted after you have embed love apple .
Observe Your Microclimate
desert have mesmerizingly wide-ranging terrain and flora that create unique microclimates . Daily and seasonal temperature swings can be utmost , due to the dry gentle wind which holds less moisture and warmth .
Microclimates can work in a nurseryman ’s favor , such as a southerly exposure in wintertime that warms earlier in spring . Trees that produce cloud shadowiness in the summertime alsoimpact your microclimate . Microclimates can also stimulate frustration , such as a low - dwell garden where freeze determine during fountain long after other position are rime - free .
Observe the area you have available to grow your tomatoes . Ideally , it would be matte , but not the lowest point of the surrounding terrain , withgood sun exposure . insensate atmosphere sinks , so the dispirited points of your property are potentially the frostiest .
Heat bank such as enceinte rocks can work in your favor in former spring to temper cold . But , they can also be scorchingly hot in summer . Access to a gentle breeze or air circulation is always good to reducediseases . blowy spot may also freeze out last ( depending on the type of hoarfrost ) .
Plant Extra Tomato Plants
you could always give away redundant homegrown tomatoes , but the saddest horticulture mean solar day is seeing your lone tomato flora die a untimely dying . Many thing can happen – under - tearing , over - watering , tomato hornworm decimation , gophers or animal equipment casualty , Curly Top Virus – so be ready .
Plant one or two extra love apple plants . you could alwaysprune them backif you are swim in too much mature fruit . plant also enjoy each other ’s company andhelp create a more humid microclimateamongst themselves .
Water Deeply When Soil is Dry
cryptical , veritable wateringwhen the dirt is teetotal down to the first knuckle joint is best practice for most harvest in most climates , and tomatoes are no elision . Deep watering encouragesdeep root outgrowth , rather than frequent , shallow lacrimation which encourages lateral increment .
try the dirt for moisture by touch first rather than watering on a strict agenda . Water deeply , but do n’t keep the dirt saturated at all times . Plant roots need oxygen too , andwater - log soilhas little atomic number 8 .
Harvest Before Watering or Heavy Rain
Before you irrigate deeply as mentioned above , harvest any tomato plant that aremore than ⅔ ripe . The tomato flavor will be most saturated when harvest from a plant life in penury of lachrymation .
Most significantly , large measure of pee can cause hairline cracks in very advanced tomato , which drastically reduce their post - harvest life . Some large - fruited or lean - skinned variety are more prostrate to cracking than others , so take this into consideration when choosing kind to develop .
Add Compost to Increase Organic Matter
Soil organic subject is a gardener ’s atomic number 79 , it is where the complex soil web lives , decays and create food for other plant life . Desert soilsnaturally tend to be low in organic thing , specially when compared with rich , saturnine soils of the midwestern United States . Desert soils can beextremely rocky , sandy , or heavy in clay which can make show a garden tricky .
Low organic subject does not have to be a death knell for your plant – remediate with compost ! If adding huge amount of compost at one clock time is cost prohibitive , it is fine to build up organic matter slowly over prison term ( mulching facilitate build constitutional issue too ) .
Choose to amend only the immediateplanting area with compost . If your garden territory is rock - strong or mostly debris , try build above - land beds with soil and compost take in .
Mulch the Soil Around the Plant
Mulching has been shown to economize water , build constitutional matter in soils , and avail even out utmost everyday temperature swings . Wheat or oat drinking straw is a widely available , relatively inexpensive mulch that works well for tomato . Other options include composition board with wood chips on top , alfalfa hay .
Mulching may have the downside of encourage slug if the filth underneath stays wet always . get hold abalance between mulching and tearing , where the soil is not overly squiffy , and keep an optic out for slug damage .
Alwaysavoid using bermuda smoke hayfor your garden or you may end up with an aggressive Bermudas smoke plague .
Use Supports When Plants Are Small
Trellis organisation or tomato plant cages are critical tokeep your tomato plant from put directly in the soil . Unsupported plant will easy pick up soil pathogens that get disease and rot yield . There is no absolute right field or wrong way to support a tomato plant , and you could get creative .
The near time to place a love apple John Milton Cage Jr. or put in stakes foreventual trellising of your tomatoesis on planting day . If that is not possible , get your backup scheme in before the works is articulatio genus - high .
hold back to trellis or order a tomato cage until the industrial plant is large , branching , and even rig yield will be a huge headache . Plus , working to lift up floppy tomato stem risks damage the industrial plant and knock off green tomatoes .
If your trellis or cage is in place on planting day , you’re able to trim it as needed as the plant grows into the trellis , urinate for a more manageable plant over the season .
Watch Out For Tomato Hornworms
Hornworms are a family of large caterpillar with conspicuous horns on their can , and the bane of gardener around the country , even in the desert .
Tomato hornworms(also calledTobacco Hornworms ) are almost inconspicuous when they are small , but give the babies two or three days of munching on your love apple plant and they will be as fat as your index finger’s breadth . Hornwormscan do a orotund amount of damageto the leaves and fruit very chop-chop .
honour your plants closely , and learn to look for signs of hornworms – rough cutting leave of absence , black or brown frass ( poop ) that face like dust when low and is about the sizing of a pepper when from tumid caterpillars .
seek to arrest the hornworms when they are small . Hand removal of the hornwormsis the best non - chemical option , plus it is spare and extremely efficient .
Harvest or Prune in the Morning
The skilful time to ferment in your plants is when theleaves are ironical . This is true for pruning , harvesting , or adding more strings or musical accompaniment to a trellis .
sour in wet flora spreads disease well and is broadly uncomfortable . Harvesting dew - extend Lycopersicon esculentum is wet and tricky oeuvre . Plus , the harvested fruits tend to have less rich flavour later as some of the H2O is absorb through the skin .
The prime time to harvest tomato is in the morning after the Lord’s Day has dry the dew , but before the tomato fruit starts to absorb the sun ’s heat . as luck would have it , good morning dew be given to dry out quickly in desert climates
Don’t Panic if Your Tomato is Not Setting Fruit
Your tomato plant life is lush , thriving , and even flower ! You anticipate get wind green baby fruit before long , but after a while you still see no fruit . What could be awry ? First , do n’t panic ! Desert agriculturist in particular are up against the most likely perpetrator : unfavorable daytime ornighttime temperatures .
Tomato fruit set is temperature sensitive , and doesbest with temps between 70 to 85 degrees . The blossoms will not determine fruit if the daytime temps are very hot , especially if your days have been in thehigh 90s or 100s Fahrenheit . Likewise , yield sets will not occur reliably with temperature under 55 degrees , which could occur in desert dark even in the summer . In fact , day / night temperature cut between the L and 90s is plebeian in the desert .
What can you do about this ? Be patient . love apple continuallymake new blossoms , and have the driving finish to procreate yield as much as you want to harvest homegrown tomatoes ! Wait out the temperatures until they become more favorable , and keep observing .
The other option is to modify the produce microclimate for your tomato . This could take shape as add together shade material above the plants to reduce daytime heat . Be sure there is still good air flow to the plants . If the tomato are implant in containers , moving them into a more shaded field until the extreme heat pass could serve cool down down their microclimate .
Conversely , if night temporary worker have been too cold , trycovering the plantslate in the day to economize some of the heat and ward off cold overnight . You most potential would need to uncover the plants in the morning . This method adds one more “ to - do ” on your lean , but should hopefully only last for a few nights , particularly in summer .
Temperature variation are the most potential reason for lack of or low fruit set on tomatoes . Other reasons admit drouth - try plants ( increase body of water ) , or overfertilization with nitrogen(do not bring any more fertiliser ! ) Most of all , do not panic and be patient . The tomato industrial plant ’s destination in life is to procreate via delicious , beautiful yield , so trust the plant is render !
Final Thoughts
Tomatoes are one of the most rewarding crops for desert gardeners to uprise . The dry mood serve reduce andimprove the flavors in the yield , so much so that “ dry - farmed ” tomatoes are in demand . The plants are in the main tough enough towithstand raging daysand dry tune , and with new tomato breed continually improving , hardy variety are becoming stock . By survey these 13 tip , desert Lycopersicon esculentum cultivator chance for success are high !
