Now that poinsettias are safely tucked into their prop trays and the threat of Erwinia (Pectobacterium) is almost over, it’s time to think about other poinsettia issues.

Root rots, nutritional issues, environmental stress and PGR mistakes can all be costly in this high-value crop.

Read on for common pitfalls and how to avoid them, and for some great video resources on poinsettia production.

This post on poinsettia problems was contributed to by Drs. Chevonne Dayboll and Sarah Jandricic.

When poinsettias get problems,  they always seem to hit hard and fast. Things like whitefly, Lewis mite, root rots, and nutritional issues can all quickly derail a quality crop. This is why scouting might be more important in this crop than any other.

Here’s a month by month guide on what you should be looking for to prevent small problems from becoming big issues.

Choose the right soil analysis for in-ground cut flowers

This post was contributed to by Lauren Vanderlingen, OMAFRA Summer Student and Christoph Kessel, OMAFRA Soil Fertility Specialist – Horticulture.

If you are using Saturated Paste Extract (SPE) to assess soil nutrients for in-ground grown cut flowers, you may be underestimating plant available nutrients and applying fertilizers that aren’t needed.

Many greenhouse growers use SPE analysis when testing growing media in the greenhouse for nutrient levels. Typically, SPE tests are used in soilless or peat-based growing substrates, the kind we usually see used in potted plant production. However, if you are growing cut flowers in a mineral soil, either in the greenhouse or outdoors, SPE is not giving you a complete report on nutrients available to your crop.

Both greenhouse and outdoor soils that produce cut flowers should be tested on a regular basis.

Garden Mums – 2019 Production and Protection Tips

This post was contributed to by Drs. Sarah Jandricic and Chevonne Dayboll.

Summer is in full swing, and so too are garden mums.  As you get ready for the next few months, here are a few tips to keep your crop on track.

Drip line irrigation can be a more efficient way of delivering water and nutrients to outdoor crops.

Irrigation method matters!

There are plenty of options for irrigation in potted outdoor crops, but not all are created equal if you are trying to maximize your water efficiency.  Overhead irrigation by boom, or sprinkler is not efficient if your pots are not spaced tightly.  Canopy sizes in the later months of production may make this impossible, especially if you choose to go with final spacing when pots first move outside.  These methods of irrigation can also lead to pots that are too dry (not watered) or too wet (over watered). Plants can only use water that makes it into the pot, so low volume drip line or tape is a more effective way to delivering usable water to your outdoor crops.
