1.Siram Nepenthes Setiap hari agar kelembaban terus terjaga..untuk nepi yg menyukai sinar matahari langsung..pilih pot yg ada nampan air. kalo tidak ada bisa beli nampan plastik di tempat orang jualan ember dsb harga sekitar 18ribu/lusin (lebih murah dan awet) 2. cara memilih nepi yg mempunyai bakat kantong merah adalah dengan melihat pinggiran daun nepi (kadang ada sedikit warna merah), kemudian bisa di liat dari batang (agak kemerahan) .meskipun nepi tersebut kantongnya masih hijau tapi ada kemungkinan pas sudah gede dan perawatan yg baik nanti akan berkantong merah.
di tunggu tips2 tentang nepenthes dari rekan-rekan forum ;D
agar nepenthes terlihat rimbun & berkantong banyak (bisa sampe -/+20 kantong dalam 1 pot) ada 2 cara yg biasa saya lakukan yaitu : 1. menanam dua individu tanaman nepenthes dalam satu pot atau 2. pemangkasan pada pucuk saat tanaman masih kecil , sehingga muncul tunas dan cabang2 baru dari ruas daun (jadi dengan begitu satu tanaman nepenthes mempunyai 2-4 cabang tapi tetap satu akar)..saya udah terapkan cara ini pada n.mirabilis, n.ampullaria, n.grasilis,n.ventrata di rumah
-rata-rata penjual nepenthes lokal di daerah saya mengikuti cara no1 (lumayan tiap beli 1 pot dapet dua nepenthes)
pada dasarnya hampir mirip stek..kalo stek satu ruas biasanya tunas yg muncul cuman satu...tapi kalo stek 2-4 ruas tunas yg muncul bisa 2-4 tunas juga....nah perbedaannya tanaman yg sudah tumbuh ini kan sudah punya akar, cuman karna di potong bagian atas pucuknyanya maka muncul tunas2 baru dari ruas2 daun....(cocok buat rencana jangka panjang)
-pengaruhnya tanaman lebih rakus menghisap air -antar satu cabang & cabang lain besar kantung berbeda tergantung jumlah serangga yg masuk ke cabang yg bersangkutan..contoh misalnya kantong cabang A lebih banyak makan serangga maka kantong-kantongnya bakal lebih gede dari cabang yg lain (cabang bukan daun)..meskipun mereka satu akar.
ini ada juga Tips dari Exotica Plants : NEPENTHES GROWING TIPS
Nepenthes grow in a wide range of environments and conditions, nearly as many as there are species. It is very difficult to summarize these growing conditions in a few words to suit all species and /or hybrids. What follow are basic guidelines to give the hobbyist or the serious collector some helpful information based on our years of cultivation in and out of greenhouses. Improvements can be made to these to suit the specific needs of specific species. Your growing environment will also influence any further beneficial modifications. Most of these will be trial and error. The basic requirements for plant growth are Light, Moisture, Humidity, Temperature, Nutrients and a suitable growing medium; this is the case for all plants including carnivorous plants such as Nepenthes. It is the ratios of these together to suit the specific plant needs that give optimal growth. Bearing in mind that the cultivation needs of plants are usually different from their requirements in their natural habitat.
In our experience this factor is one of the most important in producing optimal pitcher size and coloration. Providing there is enough relative humidity (RH) and moisture in the potting medium there can be enough light to give a tinge of red/burgundy to the leaves. Plants can be acclimatized to partial sun in the right environments, with good results. This they do quite quickly, with any damage usually limited to older pitchers burning or dehydrating but the plant remaining healthy. The next new pitcher has usually adapted and the plant will settle in. Moisture must be maintained at all times, especially in drying winds and on hot days. As a guide a bright position is acceptable with high indirect light. If plants are grown under shade cloth, a level from 50% up to about 80% produces good results. If under polyfilm, the white colours are preferred. On saying the above though, the length of the daylight hours also has a bearing on the amount of light your plant receives. In most areas the plants tolerate the loss of light hours but growth is a bit slower and watering may need reducing. Although Nepenthes do not have a dormancy period like a lot of other carnivorous plants, the lack of light does slow them down. A good indication that your plant is receiving the right amount of light is, as mentioned above, pitcher size and coloration. Another alternative if your plants are suffering from the reduced day length is to provide a couple of hours of artificial light, that is, if your situation enables you to do so.
It is important that moisture levels are maintained at all times when growing Nepenthes. Unlike a lot of the other carnivorous plant species, which like to be kept quite moist to wet during their growing season, Nepenthes like to be kept moist only. Damp is probably the best term to describe their needs. Water quality is another issue in growing carnivorous plants (CP) where Nepenthes differ. Although all CP appreciate good quality water, that is low in dissolved salts and minerals, Nepenthes are quite forgiving in this case. It is not that they don't appreciate good quality water or if available, rainwater, but we have witnessed them growing well with white mineral deposits on their leaves!
When cultivating Nepenthes it is most often advised to grow them in very high humidity, in the vicinity of 70-80% or higher. In our experience this high humidity can cause more harm than good in the greenhouse environment. Unfortunately a lot of disease and harmful bacteria also thrive in these greenhouse microclimates. We find that the humidity around the plants is usually maintained to an acceptable level by their moist potting medium with the plants growing well with the fluctuating humidity levels that normally occur during the day. These levels usually range from 50-70% during the day and up to saturation, 100%, at night. While plants growing in an outside environment will experience lower levels than this, as long as the potting media is kept moist there seems to be little detriment.
In our opinion, this is another factor that has had limits that are too strict set on it. While there is limits that specific plants will not tolerate, such as high temperatures in the case of the strict highland species/hybrids and very low temperatures with regards to the lowland varieties, again these plants are quite tolerant of temperature fluctuations. In the plants natural habitat the temperature fluctuates daily, even moment-by-moment. One has only to spend a few hours in a highland Nepenthes habitat to experience these quite dramatic temperature, humidity, light, and moisture fluctuations. One moment it could be bright and sunny, next it is cloudy with low light and 100% humidity and next it is pouring with rain, only to bathed in bright sunshine a couple of minutes later. The high ultra-violet radiation due to the high altitude and reflections from the water droplets on all the wet surfaces is the next factor to assault these plants. On the other end of the scale I have been told (pers. com.) and seen photos of N.rafflesiana growing in pure sand which was that hot in the middle of the day it would have burnt the soles of your feet if you were to walk on it. So as can be expected Nepenthes are quite tolerant and hardy.
We would suggest, with a few exceptions, an environment with some heating and some cooling to cope with any temperature extremes that may be experienced in the area that the plants are to be housed, will grow most of the species and hybrids of Nepenthes. An average temperature range of 15oC - 35oC(60oF-95oF) with some air movement will grow most Nepenthes species successfully. While the many cultivars and/or hybrids we produce here in our nursery will tolerate temperatures from 5oC - 35oC(40oF-95oF) and many have experienced extremes down to 1.5oC(35oF) without any ill effect. Higher temperatures can also be tolerated with these cultivars and the lowland species provided a high humidity is maintained.
Most growers have their preferred growing medium and one will work in one environment and one in another. The basic factor to keep in mind when selecting a potting medium is that it must be both open enough to allow good drainage but also be able to hold sufficient moisture for the plant in it's environment. Some of the commercial bark blended potting mixes available for Cymbidium and Dendrobium Orchids are suitable for Nepenthes as long as they do not contain fertilizer. We use both our commercial bark based medium and pure Long Stranded Sphagnum moss with good success. If we had to recommend one we would always choose the sphagnum moss. This gives us not only good success in growing the plants but it is also a good indicator of the plant's environment. In a lot of cases the highland species of Nepenthes grow naturally in live sphagnum moss so when the moss starts growing in our cultivation houses this is a good sign that the conditions are correct. Both the lowland and highland species grow well in Sphagnum moss. The only problem I have heard with regards to growing in Sphagnum is the tendency for it to slime up and break down quickly in areas where the water contains some minerals. A simple but effective way to overcome this is to cover the top of the pot with a layer of bark or similar material.
The basic thing to remember with the nutrient requirements of Nepenthes is that they are carnivorous plants and best results are obtained giving them the insects or small animals they have evolved to digest for their needs. We have seen plants solely supplied insects on a regular basis and their quality, size and hardiness is evidence enough.
We hope that the above tips help in the cultivation of these marvellous plants or at least have pointed you in the right direction. Above all though, if your plants don't seem to be growing well don't be frightened to experiment with the above factors as the plants usually respond quickly to the right conditions.(Exotica Plants)
