Specialist Plants and how they grow and benefit from Triplantanol feeding.


The list of plants that respond well to a Triplantanol feed is ever increasing as we build up a database from our trials and customer feedback.

Find out information about the following specialist plants

  • ROSES,

There are a number of specialist plants cultivated by enthusiasts with a passion for either their challenge in growing or the range of varieties available.  Many of these plants benefit from good feeding regimes.

Some of these specialist plants are listed below with some specific information.

HOSTAS benefit well from Triplantanol feeding.


They are highly responsive to feeding. Best results can be expected from green or blue leafed cultivars. Some of the plants with yellow leaves may be particularly sensitive to excessive feed. We suggest both autumnal feeds prior to dormancy and feeding before shoots form in the spring. Use at standard feeding rates and expect multiple crowns to increase year on year.

ROSES especially benefit from Triplantanol feeding.


Roses are known to be heavy feeders and with this in mind adopt a program of feeding with standard rose food in combination with Triplantanol powder. Applications of feed should be made throughout the summer and into the autumn with a standard feeding program. Feeding with Triplantanol can also be continued throughout the winter adopting the standard 6 week cycle.  Following feeding, when growth starts in the spring there will  be a noticeable increase in basal shoot formation, allowing the development of multiple breaks and the development of a good framework for growth and flower production during the summer months. Roses often also respond by increasing the production of flowers throughout the season, when fed with Triplantanol. Feed at standard rate for of 25 gms of Triplantanol per square meter of plant.


FUCHSIAS responds well to feeding with Triplantanol.


in the UK these plants are classified as either hardy or non-hardy. Both types benefit from the Triplantanol  application. It is suggested feeding starts at the beginning of the growing season along with application of normal feeding regime. Expect increased basal branching and production of multiple shoots. Switch mid season to flower inducing fertiliser which will work in conjunction with Triplantanol to produce abundant flower buds.

DAHLIAS should be fed throughout the growing season.

Start feeding after shoots have started to emerge from their tubers and rooting has begun. Plants in pots, tubs or in the ground will all benefit from Triplantanol feed. It is generally acknowledged that Dahlias are heavy feeding plants. Adopt a standard program of feeding in combination with Triplantanol powder throughout the summer growing season. Switch to a flower boosting fertiliser in mid summer with continued 6 week applications of Triplantanol powder. In healthy plants expect good shoot and foliage development along with abundant production of buds. Adopt bud thinning if required. Feeding should be continued all season to allow the building up of  tubers for winter dormancy. For soil grown plants feed at standard rate for of 25.gms of Triplantanol per square meter of plant.

LILIES are the most popular flower in the UK and they can flower even better when fed with Triplantanol.

Lilies can be bought as either dry bulbs or growing in pots. Usually they are bought for seasonal colour and to enjoy their long lasting flower display. A good display of flowers makes large nutrient demands on the bulb. To achieve the best flowering results lily bulbs should be fed from planting throughout their foliage stage and during flowering. We suggest application of Triplantanol powder at bulb planting time followed at 6 week intervals throughout the growing season to flowering. For best results this can be supplemented with standard plant fertiliser after shoots have emerged from the soil. Following flowering,  we suggest removal of old flowers and another application of Triplantanol. Allow the foliage and plant to carry on growing to the end of the season. For pot bought Lilies we suggest applying a top dressing of Triplantanol powder as soon as possible and allowing the root system to establish out of their pots. Unfortunately much of the UK's lily stock,  offered by either catalogue or in garden centres, is virus infected. The blame can be clearly laid at bulb marketing industry which is in almost universal denial of the problem. Indeed the code of silence on the matter allows the spread of infected plant material through the UK through ignorance and misinformation.  Purchases of pot grown plants can give some level of visual control and identification of the problem, at point of sale,  where symptomatic expression occurs.  Pot grown lilies are often produced from small bulbs. To over winter and re flower from such stock requires good levels of nutrients. Virus infected plants should be destroyed and burnt as they will deteriorate over the years despite all best efforts to provide optimal nutrition.Stargazer Lily

CITRUS are becoming increasing popular with the growth of conservatories and the range of cultivars available. For reliable flowering and fruiting it is always suggested to grow commercial cultivars rather than pip raised plants that will take many years to mature. To achieve best results within the UK a strict feeding program should be adopted. In spring and summer plants should be fed with a high nitrogen liquid fertiliser. Plants should also  be fed with Triplantanol at 6 week intervals throughout this period. Monitoring for excessive growth accordingly. From mid to late summer a high potash feed should be adopted. Plants should be given good light levels throughout the summer and winter. For fruit to develop and ripen in the winter, plants should be have a minimum of 10. degC with maintained humidity. Triplantanol powder produces large numbers of flower on Citrus plants, providing either winter fragrance of fruit development according to conditions.

Ornamental citrus provide flowers and perfume during the winter.

DAY LILIES have been found to respond particularly well to Triplantanol powder feed.

Flowering performance varies between variety. To achieve abundant flowering, free flowering varieties should be selected and plants should receive good levels of sunshine in the UK. Triplantanol leads to an increase in basal shoots and plant development.   Feed with Triplantanol throughout the growing season and a suggested autumn feed will build up the plant for next seasons production of shoots. Feed at the standard 6 week rate at a volume of 25. gms per square metre of plant.Stafford flowers in profusion when fed with Triplantanol

STRELITZIAS are not difficult plants to grow but they do have quite exacting requirements to achieve flowering. Using Triplantanol can help with their growth

All Strelitzia plants are seed raised and are either the standard size, which is also used as a cut flower,  or the smaller dwarf form developed in Holland and sold as a smaller flowering plant. The dwarf form is quicker to mature. Flowering maturity in both types is achievable when the plants have 12-18 leaves per crown. For flowering in the UK, plants are usually tub grown and stood outdoors in a sunny position for the summer. They are only brought indoors for protected cultivation after they have been subject to nighttime drops in temperature to around 8 degC. Plants are heavy feeders and should be fed with a standard liquid fertiliser for the early spring months. Mid summer this should be switched to a high potash feed. Triplantanol powder feed should be applied throughout the growing season at 6 week intervals. Plants are highly responsive to such feeding and it is not unusual for plants to produce buds from each flowering crown and flower repeatedly each year.

ORNAMENTAL GRASSES are generally not known as heavy feeders, but all the same respond well to Triplantanol feeding. As clumps mature they make demands on nutrients.  Large clumps of Cortaderia, Miscanthus and Arundo all respond to feeding with Triplantanol powder. Used at the standard rate of 25. gms per square meter of plant at the start of the growing season.  For extra large plant growth combine this with a slow release lawn feed. Container grown grasses respond well to high nitrogen liquid feed during the growing season combined with Triplantanol powder at the standard rate.

BAMBOOS respond very well to a good nutrient supply. The large stemmed bamboos all respond favourably to a good feeding regime by the production of larger culms and clump expansion. Feeding of bamboos should be modified according to geographical location around the world, indeed in warmer climates with fertile soils extra feeding may not be necessary or desirable. For the bamboo enthusiast who wishes to see larger plants Triplantanol can be used enthusiastically across the geographic zones from  temperate to tropical climates.  In the UK there are positive benefits from feeding either clumping forms or running forms of bamboo according to the constrains of where they are planted. Feed with a high nitrogen lawn food after the spring culms have sprouted and expanded fully. At the same time feed with Triplantanol at the standard rate of 25 gms per square meter. Feed every 6 weeks during the summer growing season. This will improve the general quality of foliage and cane production. However the greatest benefit will be seen the following season. Culm numbers should increase and so should their diameter and height. Judicial thinning may be necessary to favour development of the best placed canes.
