Pruning Protected Crops
Though ordinarily practiced on all the vining / fruit crops in protected farming , the goal and scheme for pruning are often misunderstood .
The sound way to define pruning for protected farming is as a proficiency used to limit the amount and character of growth to keep plant balanced . Balanced plant will be more fat and sizable , with more predictable fruit than those of unbalanced plant life .
Understanding Plant Balance
Plant Libra is well read by think what it intend for a plant to be imbalanced . All of the vining crops in this book take form a sucker at each node . If left to its own twist , a works would develop a new vine at every individual folio .
Consider that every sucker would then begin producing a sucker itself at every node , and the act of heads would start to become tough .
If a industrial plant were allowed to develop an unlimited act of heads , its finite amount of energy would be divided among so many head and fruits that growth and ripening would slow down considerably .
I have seen this happen in indeterminate basket - weave tomato production , where ripen is noticeably slower and fruit size of it is smaller . With wide spacing this might not be as much of a job , butwhen planted tightly in protect culture , unpruned undetermined plant will branch out and vie with one another .
Pruning: What Does It Mean?

Pruning is one of the techniques that allows growers to crowd as many plants as possible into a finite expanse , by limiting each plant to the minimum amount of space it needs .
Pruning not only conserves space by preventing vines from fork out , but it alsomakes a works more open and permits light and air to flow through the canopy .
This effect in a minimum amount of output simplification due to shading and disease . Fruit on pruned plant sizes up and ripens more quickly than on unpruned plants .
Andall crops that are keep clip are easier to harvest , because you do n’t have to hunt down through as much foliation to locate the yield .
Changing Plants for Balance
Pruning allow you to change the plant to balance it to its idealistic size .
For example , to grow a weak tomato plant multifariousness over a long season , you might desire to limit plant of that variety to only one vine , to pore all their energy up through the one shank , and hopefully keep it vigorous over the whole season .
If you grew the same weak potpourri grafted to a vigorous rootstock , you might be capable to grow with two heads alternatively of one .
acquire indeterminate tomato plant unpruned in a basketful weave is usually only potential in desiccated clime ; in humid region , the foliage is so obtuse that moisture build up up inside the plants ’ canopy , which leaves them prone to foliar disease .
Basics of Pruning
For specifics on how to dress each species , see the individual craw chapter . No matter what crop you are working on , though , it ’s always good to cut whatever part of the plant you ’re removing back to a living theme . Anytime you abbreviate off a plant part and leave a stub , the check stub may rot back into the stem and taint the rest of the industrial plant .
Morning is a good time to prune , especially if you prune by snarl with your hands . Plants are more intumescent in the aurora and may snap more easily than in the good afternoon , when they become more flexible .
When pruning is done in the morning , plant have the sleep of the day for wounds to dry out out , which will help them bring around without contagion . you may then drop the good afternoon trellising , because the flora are more flexible when they are transpirate more , and easier to work on without break .
Pruning Suckers
Figure 6.8 . This tomato plant life was not suckered on metre , so the sucker is now as big as and competing with the main stem . you may tell the main stem is on the left because it has the flower bunch on it . The sucker to the right hand has grown out of the leaf node of the folio below the bloom bunch .
Pruning go hand in hand with trellising as a technique to get plants to grow the mode you want them to .
In addition to hatchway up the flora to facilitate light transmission and airflow , it keeps the amount of foliage and fruit balanced , which will keep plant development and succumb coherent .
This may not vocalise like a vast payoff , until you have a short ton of yield to trade one workweek but only half a ton the next .
When you ca n’t get rid of all of it the first week , and then do n’t have enough the second , you will find yourself wishing you had pick three - quarters of a ton both weeks instead .
Pruning Leaves
There are time when you will want to dispatch some mature leaves from most of the fruiting crops . With tomato and brinjal , this is regularly done below the fruit to increase airflow .
increase airflow will cut back the amount of disease and serve fruits to ripen more quick by maintain them warmer .
old leaves can be take away without detriment to the plant because they are in the shadiness and do n’t contribute much to photosynthesis .
Pruning Flowering/Fruiting Clusters
All fruit harvest are prone to setting more fruit than they can mature . Pruning flowering or fruiting clusters is done with all fruiting crop at some point to put the amount of yield determine in balance with the amount of fruit the plant can actually support .
I have at times seen growers plant a straggle crop of cucumbers in a hoophouse or screen home . But they could get a lot more out of the same size complex body part , and get a circumstances more cuke plants into it , if they put in a footling more working class in the chassis of trellising .
It is so much easier to glean cucumbers that are held off the background than to bend over and hound through the leave .
Trellising requires an up - front investment of time in edict to make jobs down the route , like harvesting and pruning , go faster . It conk out hired hand in hand with pruning to get the plants to develop the way you require them to . It ’s also an investment in industrial plant health and fresh , vendible fruit .
