How Tos
In monastic order to keep down the prospect of inadvertent crossing , all squash varieties should be embed at a minimum isolation distance of 1/2 knot aside . Where this isolation length is unsufferable , manus - pollination of squash ensures that the plants bring forth honest - to - type seed and that the blossom are not contaminate by the pollen from another assortment .
Because the large manlike and female blossoms are easily distinguished , hand - pollinating squash can be wanton for gardeners of all acquirement levels .
Female squash flower
The hired hand - pollenation process motley among species . With plants that farm unisexual peak like squash , the unpolluted pollen from manlike flowers is carry to the un - pollinated stigma of distaff flowers .
Once the pollen is transpose , the female flower is covered to prevent pollinators that may be carrying foreign pollen from contaminating the stigma .
greenback : Squash varieties only require to be hand - pollenate or isolate if being grown for seeded player saving .
Squash Species
In total , there are four coarse species that gardeners recognize as squash ; all of which are pollinated by insects :
Though the species do not broadly produce fecund materialization when they pass over , occasionally they do ( see diagram below ) ; thus it is secure to take steps to isolate all squash varieties from each other , irrespective of species .
How to Hand-Pollinate Squash
Materials
Identifying Blossoms
The male ( pollen producing ) and distaff ( seed producing ) mash flower can be easily distinguished from each other .
When to Pollinate
Hand pollination can not set about until both male and distaff flowers are present in planting . In the eve before pollinations are perform , identify male and distaff peak that are start to show a chickenhearted flush of coloring , particularly along the wrinkle of the heyday petals . This designate that they will be quick to start the next day ( Figure 1 ) .
Figure 1.Female and male lowers will begin to show a xanthous flush of color at the tips of the petals the sidereal day before they will be quick for pollination .
These flowers are call “ tomorrow flowers . ” Generally , there will be few female “ tomorrow efflorescence ” than male . This is good because it is upright to pollinate each female with more than one manly flush . Though one male flower has more than enough pollen to pollinate one distaff peak , pollinating female with three or more different male will help to enchant more transmissible variety .
Female squash flower
Do not work with tomorrow bloom that have holes in them or that are part opened at the tip as they may be contaminated by strange pollen .
Although crush plants flower continuously over the course of the growing time of year , each flower opens for just one mean solar day , and hand - pollination demand some preparation and attention to timing .
The mental process of hired man - pollinating a squash vine heyday occurs on two sequential day . The process begins in the late afternoon of the first sidereal day , when flowers that will start the following day are identify and procure shut , and is complete the next cockcrow , when the flowers are pollinate manually .

Covering Blossoms
Seal the tips of the male blossoms close using 3/4 ” masking tape recording , dress pivot , or drooping taping ( Figure 2 ) , and tie the backsheesh of the distaff blossoms close using flagging magnetic tape ( public figure 3 ) . As the time of year progresses and the vines become progressively vigorous , it is helpful to also use tag flag to mark the location of taped flowers .
physique 2.Tear a piece of tape off roughly 4 ” long , position the tape recording half - elbow room down the petal , and fold over . Give a good press to the side that you just stuck together so the seams are completely sealed , being deliberate not to damage the flush .
cipher 3.Tie distaff flowers far enough down the flower petal that the top is altogether sealed but not so far that the stain is hurt by the tie .
Preparing Flowers
Return the keep an eye on morning after the dew has dried to locate the male and distaff blossoms that were taped , pinned , or draw exit the premature eve .
build 4.When ready , deplumate the flower petal from the harvested manlike flowers in readiness of pollinating the female .
Figure 5.When using sag to tie distaff flowers , remove the flagging or tear the petals just below the flagging when quick to hand pollinate .
bod 6.Once male and female flowers have been opened , shape promptly to fill in the handwriting pollination to preclude unwanted insect visitant .
Pollinating
Working quickly , use the manlike flowers as brushes and swob the pollen - continue anthers of the male flush onto each of the three lobe of the stigma of the female flower ( chassis 7 ) . Repeat this with the remaining male heyday before moving onto the next distaff flower .
Figure 7.Carefully rub the stamen over the pistil in the distaff flower , transfer as much pollen as possible .
Taping Female Flowers
straightaway after pollenation , magnetic tape , link , or pin the female prime shut again ( human body 8) . If using tape , treat the fragile petals mildly to avoid tear . At this point , do n’t adjure too hard , or twist around the flower at all , or it may fall off the flora .
Figure 8.Carefully record the petal of the distaff flower , making sure to varnish the tape tightly .
Flagging Pollinated Flowers
Loosely tie a piece of music of flagging tape around the stem of each female pollinated straightaway after pollination ( Figure 9 ) . This marker may simply function as a visual reminder that this fruit is for seed not for eating , but it may also include useful information , including variety and hand - pollenation particular date .
Figure 9.At the end of the hand - pollination process , distaff flowers should be taped so that no extra pollen can achieve the stamen and flag with drooping tape for identification .
Next Steps
Learn how to grow and save squash semen
To ensure workable seeds , keep seeds from at least 1 industrial plant . When maintaining a mixed bag over many propagation , write seed from 5 – 10 plants . If you ’re make unnecessary seeds for transmitted preservation of a rare variety , pull through seed from 25 plants or more .
Assessing Seed Maturity
At seed maturity , summer squash rackets will be much magnanimous than their market- mature size , and they typically undergo a color variety . Fruits are quick to harvest when the rind is too unvoiced to dent with a fingernail and the stem is teetotal .
Winter squash are typically matured when fruit are unremarkably harvested for eating : after they vary color and yield stems are dry .
Harvesting
All types of squash welfare from a period of post - harvest ripening during which the seed carry on to mature . Fruits are typically confine for at least 20 day beyond fruit adulthood before their seeds are extracted .
Although they can further ripen on the vine , squash are susceptible to disease and sunscald , and it is generally recommended that fruits be harvested and moved to a shady position or indoors for post - harvest ageing .
commercial-grade seed agriculturalist process winter squash after 20 days , but seeds can be extracted from squash by and by in the winter instead , when the fruits are used for cooking .
Cleaning Seeds
To remove squash cum from the fruits , simply split the squash racquets in one-half by shallowly cutting through the rind from top to bottom on both sides and part the two halves . tailor through the center of the fruit can damage seminal fluid .
Next , scoop out the seeds , massaging them gratis from the pulp as much as possible . Transfer them to a wide - mesh strainer — or any other container with initiative large enough for flesh and chain to perish through — for rinse off .
Running the seed under a stiff stream of water will help dislodge the seeds from the pulp magazine . When sour with mixture whose semen are hard to separate from the flesh , soaking the seed for a few time of day can ease cleaning . Large screens made from quarter - inch hardware cloth work well for cleaning and rinsing big batches of ejaculate .
Immediately after cleaning , rinsed seeds should be spread out to dry out in a thin layer on screen door , if possible .
Squash seeds , the two germ show on the right of this simulacrum , are fully dry when they can easily be snapped in one-half .
Processing Seeds
pour can be a good way to dissever viable seeds from lightweight and developing seeds . Decanting simply mean pouring out the smorgasbord of piddle , pulp , and immature seeds off the top of the liquid , while keeping the mature , viable seed at the bottom of the glass . This method acting is only good for some types of squash rackets because even the viable source of many potpourri will float , rather than sink .
Alternatively , winnowing can aid separate lightweight and developing seeds once the seeds are dry .
When fruits are processed individually – such as when winter squash seeds are distil as a meal is prepared – the seeds should be clean and then mix in in and lay in with source of other fruit from the same planting , in ordering to maintain the genic multifariousness of the seed harvest .
Storage and Viability
When store under nerveless , teetotal conditions , squeeze seeds can be expected to remain viable for six years .
