oncidium ornithorhynchum plant in flower

Oncidium ornithorhynchum is a fragrant and easy plant to grow. See how this specimen plant has developed over 50 orchid bulbs (psuedobulbs) over a number of years feeding with triplantanol products. This plant makes an ideal beginners orchid plant if you love fragrance. They are available as a houseplant each winter.


Simple feeding of Orchids with Tgrowbags.


Tgrowbags work especially well for feeding orchids, especially the tropical pot plant orchids that are so widely available in the houseplant market in temperate climates. Here orchids are the number one plant in the marketplace.

Tgrowbags have been specially developed from our Triplantanol Orchid feed as an easy and convenient way to feed and care for your orchid plants.

Tgrowbags N.P.K. 17-3-9 + organic growth regulators.


Rate of use: Use x1 Tgrowbag / 12cms. (500ml. volume) pot.

When watering your orchid plants do consider a number points.

  • For temperature sensitive plants such as Phalaenopsis (moth orchid) make sure the water temperature does not chill your plant. Make sure it is above 18degC. A chilled Phalaenopsis orchid will die very quickly!

  • Phalaenopsis are grown commercially at 28degC which is the optimum temperature for quick growth, aim to to keep your plants approaching those temperatures. Phalaenopsis like warm conditions so they are very well adapted to centrally heated houses. They do not like to be in houses where the are subject to a chill at night. A drop below 10degC puts your plant at risk of dying.

  • Make sure your orchids do not dry out. Water when moisture is required.

  • Different Orchids require different conditions. For detailed information research your plants on the www or from good reference books.

  • Do not completely rely on the guidance labels produced by the growers to market their plants, as these often have abbreviated and generalised information.

  • Not all orchids are warm growing, so some will thrive in a cool room or a cool conservatory. Odontoglossum, Cymbidium, Zygopetalum and some intergenric hybrids last better in flower, in cool conditions. If your house is not warm you can easily find cool growing plants that are better adapted to your conditions.

  • Flower production is dependent upon cultural conditions including correct seasonal feeding.

  • Orchid require good quality water to thrive. Avoid watering with hard water (you can easily determine this if your kettle has calcium deposits). Rain water is usually best, but make sure it is suitably warmed.

  • Natural soft water with low mineral contents is usually suitable.

  • NEVER use water from a water softener as it will kill your plants. For customers living in countries that derive the water from desalination, this should NOT be used for watering orchids.

  • If your plants have roots that are dying, repot in suitable fresh orchid compost and allow roots to start to re grow before feeding with Tgrowbags. A sick plant or a plant that had experience a cultural shock or has stale compost should be repotted and brought back to health before feeding. There is much information on the internet regarding orchid cultivation. Look up the information for your particular orchid type and proceed according. Orchids have evolved as tough plants to survive their habitat conditions and they respond quickly to good cultivation conditions.

Orchid plants put a lot of energy into producing flowers. In Phalaenopsis it can be seen that often when the plant is in flower, it does not grow any new leaves and root growth is minimal. However when flower production has stopped, either due to the end of the flowering cycle or flower stem pruning, vegetative root and leaf growth resumes.

If your plant is growing well, there is a good case for feeding with Tgrowbags to help with building up the plant for the next flowering season. Although Phalenopsis plants are not heavy feeders, they can grow continuously when condition of heat and light are good. They do not store their energy in storage organs like many epiphytic orchids, so need to be supplied with a constant nutrient source.

Tgrowbags can be used to feed Phalaenopsis, Paphiopedilums, Odontoglossums, Oncidiums, 'intergenerics' Zygopetalums, Cymbidiums and many other orchid genera.

We would urge some caution in feeding some small tropical epiphyte orchids as they are sometimes particularly sensitive to salts with their fine root system. Always proceed with caution with these genera and be sure not to over feed your plants.

You can also combine normal liquid feeding at half dilution strength with Tgrowbags, to improve growth and regulate the vegetative or flowering growth, through the seasons.

Tgrowbags were especially developed for feeding tropical pot plant orchids. These are the most widely available plants in the houseplant market and provide exceptional value for money and flower power.

We are confident that if you can grow your orchids well, the addition of a Tgrowbag feeding regime will help you produce results better than ever before.

We urge all customers to keep digital records of the effect of Tgrowbags to show how your plants have thrived! Do send us your pictures, as we always enjoy seeing plants grow and what can be achieved!

Phalaenopsis, Paphiopedilums and Zygopetalums grow especially well with Tgrowbags.
