Hydroseeding works very well when you have tough conditions.
A monsoonal burst of more than a week, over 100mm of rain in less than 2 hours initially, continued ongoing heavy rain during the week [ more than 250mm], relatively short sunny breaks and lots of heavy cloud..........
Yes, a small amount of washout, but very small areas affected.
And at nine days from sowing when seedlings first appeared ..........was .looking very promising.
A true minimal cultivation operation based around a spray with glyphosate [ Roundup], a quick respray to kill off a few small missed spots after 4 days, hydroseeding with fibre mulch and zoysia seed after 7 days, when all plants were dead.
The recommended option of a short period of irrigation several times each day during sunlight hours was used [3 x 10 mins each time] to keep the surface damp - raining or not, with a slightly longer period early each morning to ensure adequate moisture at the surface - both VERY critical. This irrigation started once sown, and monsoonal conditions did not start for several days after sowing. Conditions at sowing were very hot - days around 34-35C, nights at 27-29C.
By day nine it was establishing very well. Yes, a few legume weeds were emerging which can be hand weeded, but will most likely be spot sprayed in a week or so.
There will be more of the story to come in the next two months as it develops.
So far it is a very promising early establishment.
|hydroseeding with seed, fertiliser and mulch|
|Completed hydroseeding of oval - green from fibre mulch|
|seedlings at 11 days from sowing|
|yes - a few weeds too among seedlings at 11 days|
|A bit of washout but still plenty of seedlings - at 11 days|
|general view at 11 days from seeding -- plenty of seedlings emerged - sun needed to boost growth|
