Bloem Living supplies retailers with plastic containers and garden goods, and this summer their distinct and attractive colored pots showcased some of our own distinctly designed combos.

NEW FOR 2024: MYP EMPLOYEE COMBOS

For the first time ever, MYP’s talented and dedicated employees showcased their design expertise in our employee combo display area, and garden visitors then weighed in on their top pick from our employees’ masterpieces! This year’s “Employee People’s Choice” honor goes to Mike Wilcox, MYP’s Lead Maintenance Tech – Peach Ridge. “When the idea came out about making our own combo, I wanted to participate but had no idea what to mix together. As I walked around the greenhouse each day at work, I found varieties that I really liked and noted them down to put in my combo. I took those preferred varieties and followed the diagram to come up with my combo.” Look for this popular trial category in next year’s trial garden!

YOU ASKED, WE TRIALED: 2024 FEATURE TRIALS

Each year our staff selects issues of interest to our customers and trial garden visitors for our annual features trials. The 2024 feature trials were designed to address several questions growers have posed to our trial garden staff: How many plants per pot do you use? How much fertilizer do you feed them? How much sun can foliage houseplants take?

FEATURE TRIAL: PLANTS PER POT

Trial garden visitors have often asked how many plants are grown in each of our pots, assuming that we use more than is typical or feasible for many growers to use. For one of this year’s feature trials, we selected some top varieties in a range of genera and grew them out in our standard 16” stone planters with either 3, 4, or our standard 5 plants per pot. We grew out these varieties side by side and tracked their development with photos at designated intervals throughout the summer. Here’s what we found:

1.

Some genera exhibit significant differences between 3 and 5 plants across the growing period, such as Begonia Adora™ Satin Rose and, surprising to us, Ipomoea Marguerite. These plants grew significantly larger as a 16” container with 5 plants in them than they did with 3 plants in them.

2.

Many varieties showed very little difference between 3 and 5 plants per pot. Varieties like Coleus Talavera™ Moondust and Geranium Calliope® Large Dark Red grew nearly identically with 3-5 plants per pot throughout the entire growing season.

3.

Planting 4 plants in our 16” pots seemed to provide consistently strong results. When 5 plants are potted, they may compete for resources which may weaken those plants. If there are just 3, then they can share the fertilizer and water and grow into strong and long- lasting planters for homeowners. How many plants a grower puts in a pot can also be a function of how long they want that pot to grow before it is saleable. When timing is key for growers, 5 plants per pot will fill in more quickly and be saleable sooner. In those cases, a grower might choose more plants to get faster turns on their benches.

4.

FEATURE TRIAL: FERTILIZER RATES

Visitors often inquire about our feeding protocols. We designed this second feature trial to educate growers and retailers alike, and with our first-ever open house for homeowners this year thought they would also benefit from learning about the importance of fertilizer. This trial featured top-selling varieties across many genera at 3 different fertilizer levels: 1) Our standard daily liquid fertilizer at 150 ppm N 2) Just clear water but planted with some slow release fertilizer in the pots 3) No fertilizer and no slow release, to mimic homeowners who only ever water without feed Here’s what we found: Across all the varieties, the line that got the garden’s standard and daily feed performed the best and grew into beautiful, large plants. These results confirm what we expected: regularly fertilized plants perform better and look better for longer in the growing season. Homeowners looking to grow large, healthy, and long-lasting plants are advised to install a fertilizer injection system and feed their plants daily this way. 1.

Slow-release fertilizer in the pot does help. In the photos of petunias, verbena, and lantana the pot which received the slow release grew for about the first month and stayed in flower looking relatively good. As the summer wore on and they were watered every day with just hose well water, that slow release gave out and did not carry that pot through the entire summer.

In recent years, consumer interest in tropical, foliage, and houseplants has steadily grown. Houseplants and tropical plants are very different types of plants, but homeowners following the houseplant trend don’t always know the difference between shade-tolerating or filtered-light tolerant houseplants such as African Violets or Peperomia and tropical variety houseplants which tend to prefer high light. We conducted this trial to evaluate which tropical, foliage, and houseplant varieties can tolerate growing in full sun. What we learned: There are many tradescantia varieties, and these are often considered indoor foliage plants. After growing out multiple varieties of these, we learned that some performed very well in our full sun trial and would work well mixed in with annuals in combination planters, such as Nanouk, Purple Bridal Veil, and Sillamontana. These varieties all feature different leaf shapes, sizes, color, and even texture that we are looking forward to mixing in some 2025 combos. 1. FEATURE TRIAL: FOLIAGE IN FULL SUN

Pothos, typically used indoors but also considered a tropical plant, also performed well. When plant moves from the indoors or even from in a greenhouse to outside in full sun, it will need to acclimate and may experience some foliar burning, but once that acclimatization occurs, then the plant will grow new leaves that are fully sun tolerant. We liked both the variety Golden and Jade in our trials. 2.

Monstera, featuring a leaf with holes in it, is a very popular houseplant which also exhibited tolerance for sunlight. The variety Minima performed well in sunlight as well. 3. Not all trialed plants tolerated full sun, but we were pleased identify several multifarious varieties. At MYP, one of the ways we use the trial garden results is to identify plants to include in our program the following year. This foliage trial will impact what varieties we are offering in our ’25-’26 catalog.
