Cereus peruvianus showing the boosting effect of Triplantanol feeding

A pot of Cereus peruvianus showing the growth boosting effects of Triplantanol feeding.

This plant has put on a very distinctive spurt of growth on its terminal shoots. This is a result of feeding with Triplantanol last growing season. You can see how the combination of fertiliser, alfalfa, triacontanol and other growth regulators have worked together to produce cell expansion and greater growth.

Tgrowbags contain a special mix of Triplantanol for feeding houseplants including cacti.

Cacti and succulents are becoming increasingly popular worldwide. They have a number of advantages commercially with regard low heat input and toughness. They also provide the customer with plants that are relatively easy to grow and can withstand a level of abuse without dying. They are often the plant that starts to get people enthusiastic about growing plants on the windowsill and around the home.

Traditionally cacti and succulents were grown with very little attention to feeding. However nowadays most people feed their cacti and to get good results a feeding regime needs to be adopted for the life of the plant. With no food plant will deteriorate and it is more susceptible to disease and will not be a 'thing of beauty'.

It is a myth that cacti can survive in the natural habitat with no food. The reality is that in the natural habitat there is always food available which the plants survive on and grow bigger over the years. They do not simply survive on sunshine!

Tgrowbags provide a good and easy way to feed your plants.

Cacti and succulents are usually fed when they are in active growth. Active growth is usually associated with watering. Tgrowbags feeding is an easy method to achieve feeding during this cycle.

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


Watering and feeding from above.

Simply place a Tgrowbag onto the surface of the pot growing your plants. Position it away from the plant to the edge of the pot. If there is restricted space you can roll the Tgrowbag into a tube and position it. When watering from above, ensure that the bag is wetted with each watering.

This method of feeding has the advantage that food is readily available with each watering, however the expanding organic mix is kept away from the main growing stems. Nutrients will dissolve and pass thought the free draining potting mix.

Watering and feeding from below.

Place your plant into a deep saucer, which is big enough to hold sufficient water for a single watering. As a guide, the saucer space should be bigger than the standard watering space below the pot rim to the potting compost level, for a newly potted plant.

Ensure the plant pot has a good sized hole or multiple drainage holes that are not blocked off by roots. (Some root emergence through the drainage holes can be tolerated, especially if there are multiple holes) Importantly the pot should not be crocked or have drainage material that blocks water diffusion or creates an air gap.

  • This method of feeding is used when no moisture is required at the surface of the pot. Many cacti and succulents benefit from watering from below.

  • It allows roots to develop deep into the base of the pot as they search out water.

  • For plants with swollen bases or caudex forming succulents, the potting mix surface is not disturbed with watering and so display is better achieved.

  • Large rosette forming Echeveria often leave little space for watering from above.

  • Some spreading Mamillaria and Rebutia plants quickly cover the complete pot surface so watering from below allows a more even application of water and food.

  • Echinopsis, Trichocerus, Lobivia and Chamaelobivia are grown by this method extensively in the cooler parts of Europe.

Schlumbergera Samba Brazil is one of the most exciting new hybrids to emerge in recent years

Schlumbergera Samba Brazil is an outstanding new variety introduced from Denmark for the European pot plant market. Its colour combination is unique.

Included are Schlumbergera, Rhipsalis and the various inter generic hybrids. Commonly known as Thanksgiving, Christmas and Easter Cactus in various parts of the world,

These plants require a moisture retentive compost and reasonably high levels of humidity when in active growth. Their origins are from the Brazilian rainforests where they grow as epiphytes.

Watering and feeding should be when plants are in active growth which is usually the spring and summer months. Although plants should not be allowed to dry out at the roots, it is well known that after flowering a period of no water should be adopted for 2-3 weeks. This is to ensure a the plant recovers from the flowering. Some growers will feed when he plants are in flower so that the plants are not nutrient deficient as they slow down for winter. The effect of growth boosting triacontanol can allow the greater formation of new shoots in the spring.
