Germination Guide

▼

Seed Preparation

Contents: 4 fresh, viable seeds. Pre-treatment: Soak seeds in warm water for 48–72 hours to soften the seed coat and promote faster sprouting. Change water daily to prevent fermentation and maximize germination potential.

Sowing Medium

Use a blend of 50% coarse sand or perlite and 50% cocopeat or quality germination substrate. Ensure free drainage to prevent root rot during the germination stage. Excellent drainage is essential for healthy seed development.

Planting Depth

Plant each seed approximately 2–3 cm deep. Lightly cover with medium and maintain evenly moist conditions without overwatering. Ensure consistent moisture for optimal germination success.

Temperature & Humidity

Optimal Range: 28–32°C for best germination results. Humidity: Keep medium humidity (70–80%) using a plastic cover or mini-greenhouse setup. Provide ventilation weekly to prevent fungal development.

Watering & Light

Keep the substrate moist but not soggy. Overwatering slows germination and can cause fungal issues. Use a spray or misting bottle for controlled moisture application. Provide bright, indirect light initially; gradually introduce stronger light as seedlings emerge and develop.

Germination Timeline & Transplanting

Typical germination occurs within 1–4 months, sometimes longer depending on ambient temperature and moisture stability. Once seedlings form their first true leaves, transplant them into individual containers with a rich, well-draining mix. Handle carefully to avoid damaging the tender taproot.

Plant Care Guide

▼

Light Requirements

Young Plants: Prefer bright, filtered sunlight until acclimated. Mature Palms: Thrive in full sun for optimal trunk color, crown development, and overall vigor. Gradual transition from shade to sun prevents leaf scorching.

Soil Requirements

Prefers deep, fertile, and slightly moist soil with excellent drainage. A blend of sand, loam, and organic compost is ideal for vigorous growth and healthy root development. Avoid compacted or poorly draining soils.

Watering & Fertilization

Water: Provide consistent watering during the growing season. Do not allow soil to dry out completely, but avoid standing water around the roots. Fertilize: Use a balanced palm fertilizer (e.g., 12-4-12 + Mg + Mn) every 2–3 months during active growth to maintain lush leaves and a healthy trunk.

Temperature & Hardiness

Roystonea borinquena thrives best in warm climates between 20–35°C. It tolerates short periods of cool weather down to about 5°C but should be protected from frost to ensure healthy growth and development.

Pruning, Maintenance & Container Growing

Pruning: This palm naturally sheds old fronds as it matures. Remove only brown or damaged leaves near the base to maintain a clean appearance. Container Growing: Young plants are well-suited for large containers for decorative use on patios and courtyards. Repot every 2–3 years to allow for root development and refresh soil nutrient content.

Pests & Diseases

Roystonea borinquena is generally resistant to pests, but occasionally monitor for scale insects and mealybugs. Use neem oil or insecticidal soap if necessary. Maintain good cultural practices including proper watering and air circulation to prevent disease issues.

Durable
Color: S6-muti-color
The balls are great for chewers. The squeaky didn’t last long but they are perfect for the ball launcher.

The squeeker isn't durable, but the balls themselves are.
Color: S6-muti-color, Color: S6-muti-color
I have two 70+lb, ball obsessed dogs (a field bred Golden Retriever, and an Old Time Scotch Collie), and these balls are living up to the abuse they're receiving. In the fall we always lose a ball or two in the yard due to getting lost in leaves or longer grass, so I always try and buy a multi pack at the start of the season, so went with these this year. I'm glad I did. Great price for a 6 pack, they fit the medium Chuck-It launcher (a little loosely, but they throw just fine), have great bounce, they FLOAT (which means I didn't lose any at the beach), and they're super durable to the dreaded "mouth squish." The squeaker dies pretty quick, like, within a day, but it isn't the kind that can fall out or choke your dog, so no worries there. The boys are happy, I'm happy, my wallet is happy - I've already ordered another pack.

Great Value for a ball my dog loves!
Color: S6-muti-color
I wish these ball were in the subscription program! My dog gets sooo excited by the new ball, but her interest in things lasts for a few days. She kills the squeak within 11minutes, but the squeaker stays in place rather than becoming a chocking or swallow hazard, and she still loves to chew it. Next, we must throw the ball approximately 723 times the first day, possibly 496 times on day 2, and just 3- 4 on day 3, at which point she will chase the ball before hollering "it's over here if you need it," while she checks on the chipmunk den. We currently have 17 of these balls in our yard (because we have given several leftovers to a less discriminating doodle next door). These balls hold up really well, get her extremely active for the first couple of days, and are a much cheaper than doggie daycare (after an active morning with a new ball, she is happy to chew on it and sleep much of the day). I always have these on hand!
