The crocus plant is a planted as a bulb, which will grow to produce flowers. The correct care of a crocus plant will mean the difference between flowering and not flowering. If the plant does not have the correct lighting, watering and soil type, it will become prone to pests that can damage the plants leaves and root system inhibiting the plant, which means that it will not flower.
Keep the plant in a location where it will receive indirect sunlight. The best locations are on the west, east or south side of the building. The location should be bright, but direct sunlight will cause the soil to dry quickly and the plant will show signs of wilting.
Keep the crocus in a soil that has good drainage, but holds water. A good potting soil with a little sand mixed in will make a good combination soil for this plant. It is a good idea to repot the plant every two to three years in new soil. The old soil loses it texture and ability to hold water after a few years. Note: When planting or transplanting the bulb, make sure that it is down in the soil twice as deep as the size of the bulb. If the bulb is 1 inch tall, plant it 2 inches down in the soil.
Place the potted plant in a tray with gravel so that the water that drains out of the pot will provide medium humidity to the plant and the pot will not sit directly in the water.
Water the plant to keep the soil wet, but during the summer, water less because the plant will become dormant. Keep the soil moist and not wet. Note: This is an autumn flowering plant. For other crocus plants, water during the spring and summer and reduce watering in the fall and winter months.
Control pests with mild soapy warm water. The plant is prone to mites, mealy bugs, scale and whiteflies. Wipe the leaves with the soapy solution and a washrag. Make sure to get underneath the leaves. Repeat this process until all signs of pests are gone.
