Siram rumput pada waktu awal pagi. Ini memberi masa untuk air meresap ke bawah dan boleh di ambil oleh akar rumput bila matahari mula panas di waktu tengahari. Bila siram, siram secara banyak dan sekali sekala (deeply and irregularly): ini akan mengajar akar rumput untuk tumbuh panjang ke bawah untuk mencari air. Jangan siram secara berjadual, contohnya setiap pagi tiap tiap pagi. Check sedalam dua inci dan lihat jika tanah masih basah; tak perlu siram.
Untuk penjaga rumput yang di potong pendek dan terdedah kepada matahari seperti green padang golf dan orang yang memotong rumput menggunakan mesin galas belakang: amalkan ‘syringing’ atau siraman ringan pada waktu tengahari. Ini akan menyejukkan permukaan atas tanah. Cukup sekadar dua putaran sprinkler atau satu nyanyian lengkap “Negaraku” sewaktu menyiram.
Penjaga rumput juga patut menggunakan ‘soil wetting agent’ untuk membantu air tembus ke bawah. Ingat: ‘SOIL’ dan bukan ‘leaf wetting agent’ atau ‘plant wetting agent’. Kita boleh juga melakukan penebukkan tanah sedalam seinci dua untuk membantu aliran air terutamanya di kawasan kering. Tapi awas, kalau tak cukup siraman air, kawasan di tebuk itu akan kekeringan di bibir atasnya.
Akhir sekali, Tuhan telah jadikan rumput akan menjadi dorman dan coklat bila cuaca panas berpanjangan dan tak cukup air. Bila air ada, ia akan kembali hijau. Ini untuk rumput sihat dan spesis tertentu Bermuda dan Zoysia serta Cowgrass dan Serangoon.
Water your grass (golf course, field, lawns etc) very early in the morning. This will allow the water to be soaked into the ground before the sun can evaporate the water and the grass has available water when in the heat of the afternoon. Watering in the evening may mean you are watering dead/dying/dormant/suffering grass: You’re too late! Plus water in the ground at night may cause diseases and algae.
The catchphrase for watering grass is “deeply and irregularly”: this will train the grass to grow longer roots to search for water. Watering like clockwork every morning will encourage shorter roots and may waste water, especially for shaded areas. Before watering, poke the ground and check, if the soil is moist; take a chance and skip watering. Another test is if you can see your footprints on the grass, that means there is no moisture in the leaf and you need to water there and then. When you water, water until you judge water has penetrated at least two inches of soil (does NOT mean two inches of water). Newly planted grass will have shorter/no roots and needs to be watered more often, not with more water. For example; newly planted stolons/seeds may need watering every hour with just enough water to ensure the stolons are moist in this weather. Water too much and you have runaway seeds/stolons.
Professional grass managers should look at using soil wetting agents; it will increase water penetration – among other things. For sun-exposed grasses that are cut at low cutting heights such as golf course greens and lawn owners who cut their grass once a month with back pack cutters (especially if you use nylon strings: you guys should try artificial turf) there is this thing called syringing aka very light watering in the afternoon heat. Yes at 12pm. Two full turns of the sprinkler or sing one Negaraku song till finish; complete watering. Forget the theory that the water droplets will act as lens to focus the sun’s rays: the heat will evaporate it before any damage is done. Syringing will help to cool down the top inch of the soil. Hot soil will injure the grass’ roots.
Dried out. But the long-term benefits will outweigh this short term aesthetic issue.
We can also do shallow spiking, slicing or solid tines with small diameter tines just to provide areas for water to penetrate. Or just poking with anything sharp for one or two inches in dry areas, will help. But not enough watering will cause the edges of the slits/holes to dry out.
Lastly, don’t fret that your grass has turned brown. Most healthy grasses will go dormant when faced with prolonged dry weather and will green up again when there is adequate water. This goes for Cowgrass, Serangoon and most hybrids of Bermuda and Zoysia. Yours didn’t last year? That’s what you get when you buy new types of grass you don’t know enough. Your grass is not healthy? Its usually due to poor maintenance. Let it die and switch to artificial grass next year. No I don’t sell artificial grass, I just sympathise with poorly managed living grass.

1. Untuk rumput yg baru ditanam, berapa kerap penyiraman perlu dilakukan?
2. Bagaimanakah cara untuk meratakan rumput yg dilihat agak tenggelam kesan daripada pijakan semasa proses penyiraman dilakukan?
Terima kasih.

Siram sikit tapi selalu. Umum nya, hari pertama sejam sekali. Hari kedua 2 jam sekali. Hari ke3 3 jam sekali. Hari ke 4 hingga 14; 4 jam sehari. Lebih kurang camtu bergantung cuaca.
LEPAS rumput dah establish, selalu nya sebulan, lakukan topdressing. Sedikit tapi selalu jugak.
