Is it advisable to use root hormone to speed up growth of strawberries?

Strawberry    None Given

Question posted on behalf of Mwaura Gathuka from Kenya.
I have been using root hormone to speed up growth of my strawberries. Is this advisable? The root hormone i have been using is AZATONE hormone. i usually deep the root end in a solution of the rooting hormone for 24 hours before planting.

Please tell us the name of the root hormone please so we can provide a detailed answer.

Rooting hormone is usually a powder, liquid or gel containing indole-3-butyric acid (IBA), a plant hormone which promotes the formation of plant roots. It is therefore commonly used in plant propagation, particularly to encourage the growth of roots on stem cuttings.

The use of IBA on your strawberry plants is likely not necessary if you are growing up plants which have been obtained by splitting the crown as the plant should already have been cut with some root. However, rooting using IBA may be beneficial if you are propagating from runners. Runners, or stolons, are strawberries way of reproducing. The mother plant sends out a horizontal stem from the base (called a runner; see diagram) and a new daughter plant grows, setting down root where soil conditions are favorable. The daughter plant will generally have no problems doing this but speeding the process with rooting hormone can be beneficial as the quicker the plant becomes established, the less susceptible it is to certain diseases. Indeed, some rooting hormones also incorporate a fungicide which will give the plant some extra protection while they establish.

Are you able to provide us with any additional information on the type of rooting hormone you have available to you? It would be very helpful for us to know what you have available to you in your area so that we can help others.

As Lindsay indicated above, indole-3-butyric acid (IBA) can improve rooting. However, typically strawberries are very quick to grow new roots, so in commercial production of transplants, we do recommend the use of growth hormones to improve rooting. Meeting the plants basic needs, such as supplying sufficient moisture and controlling weeds, is likely to have an equally (or greater) positive effect on yields from the time of rooting to harvest, and at a lower cost. You also may want to consider whether you might want to save the rooting hormone for other plants that might be more difficult to root. If AZATONE contains a different growth hormone than IBA, it's possible that it could actually inhibit rooting at the wrong concentration, and the acceptable concentration could be quite narrow. One last point is that there may be regulations governing whether this is an acceptable (i.e., legal) use on strawberries, as the time from rooting to fruit production is relatively short. Can you provide the active ingredients in AZATONE? As an example, this may appear on the label as something like "Indole-3-butyric acid 0.4%".
