A simple trick makes phalaenopsis orchids this big

You can ensure that your orchids are fertile by choosing quality seeds or buying mature plants that have already flowered.

Orchids need about 60% sunlight, so it's important to place them in a location with moderate sunlight exposure.

You should repot your orchids when the roots start to outgrow their current pot. It's best to use a larger pot to allow for better root development.

There is no set schedule for watering orchids. It's best to water them when the planting medium is dry, usually every other day or every three days.

You should use a growth fertilizer with a higher nitrogen content than phosphate and potassium. Avoid using sowing fertilizers or flowering fertilizers.

You can use insecticides and fungicides once a month, preferably in the afternoon to avoid scalding the leaves. It's also important to maintain good air circulation to prevent diseases.

To ensure the health and fertility of your orchids, place them in a location with moderate sunlight, repot them when necessary, water them appropriately, fertilize them with a growth fertilizer, and control pests and diseases. Good air circulation is also important for their well-being.
