Rhizopon has been marketing growth regulators since 1940. Currently, we provide three types: 3‑IAA, 1‑NAA and 3‑IBA. Each of these is available in powder form (in various concentrations) or as water‑soluble tablets. Even the smallest order is always sent to the customer with the greatest of care.

For the past 15 years, our marketing strategy has been based on looking for methods to perfect the commercial cutting process. As a result of our efforts, we’ve been able to make a significant increase in the number of cuttings that grow into mature plants at our customers’ nurseries. The main key to our success has been to pay attention to the biological needs of the cuttings. Needless to say, increasing the number of successful cuttings means that profits increase, too.

Again and again, taking into account the biological needs of cuttings improves results. What we are proposing, then, is a revolutionary approach: propagators ‑coddle your cuttings!

Coddling your cuttings is easy

As a modern propagator, you already have all the equipment you need to meet the biological needs of your cuttings. You may have all the necessary knowledge, too. Now all you need to do is devote a bit of attention to fine‑tuning your process by adjusting your methods to the biological needs of your plants.

Why coddle your cuttings?

The main reason for coddling your cuttings is to allow them to develop good roots. You already know the importance of good rooting, but let’s refresh your memory about why it’s so important.

‑ Roots provide a plant with water. Water, combined with light and air, enable the plant to make its own food.

‑ Ideally, every vascular bundle in a plant’s stem has its own root. So the more roots a cutting develops, the more vessels have their own supply of water.

‑ The sooner a cutting has roots, the less it has to rely on its limited, previously stored food supply.

‑ A well‑rooted cutting can react to its surroundings; a well‑rooted cutting is ready for delivery. Easy ways to help your cuttings Simply give your cuttings the best chance to form roots. With good roots, the cutting will help itself. First, however, you have to give your cutting the best possible parent plant.

‑ The best parent for a cutting is a healthy, well cared‑for plant that has stored an abundant food supply.

‑ The best cuttings from a good parent plant come from the biologically immature part of the parent plant which is actually the oldest part of the plant physiologically. This ‘cone of juvenility’,  is a cone‑shaped section of the plant located low on the stem. (Actually, this is the part of the plant that is least likely to start flowering. Since flowering always takes place on the outside and upper side of the plant, the inside of the lower part of the plant is the ‘cone of juvenility’.)

You can ensure obtaining the greatest number of shoots for cutting purposes by pruning back the outer tips of the plant. By removing the growing points from a plant, it produces more new shoots.
‑ Prevent dehydration, but don’t make the substrate soggy. Provide a good supply of water to the roots, but supply good drainage as well. Adding coconut fibre to the substrate often improves drainage.
‑ Root initiation takes place best when the substrate is between 20 and 30ºC. When the root tips become visible, the temperature of the substrate should be decreased to 20ºC. Meanwhile, keep the air temperature a bit cooler.
‑ The ideal surrounding temperature for the cutting is the same as that for a mature plant.
‑ The night‑time temperature should be 5 degrees lower than the daytime temperature. This slows down food consumption at night when no light is being supplied to produce food. A hungry cutting is not a happy cutting!
‑ Use growth regulators to encourage the cutting to develop roots all around its base instead of just at certain points.
‑ Later, spray the cutting with growth regulators now and again to slow down the growth of the cutting temporarily, thus allowing it to develop better roots.
‑ By supplying an atmosphere with 800 p.p.m. of carbon dioxide, the cutting will develop more and healthier roots.

Why haven’t you been coddling your cuttings before?

We don’t know. It’s easy and profitable, and businessmen usually don’t neglect anything that’s easy and profitable. Maybe you thought coddling was something only nannies do. Now you know it’s also for sensible businessmen like yourself. (P.S.: Wise businessmen also coddle their wives, their personnel, their customers, their inventory, etc.)
