Though white clover seed can be planted in a wide array of soil types, it thrives best in moist substances such as clay. It grows well in a medium pH mixture. In addition to ample moisture, it needs lots of drainage in order to sprout properly. It should be allowed to grow to about 4 to 8 inches (10 to 20 cm) before it is mowed for the first time. The seeds grow best in moderate temperatures as warm summer weather can dry up much-needed moisture.
White clover seed is typically mixed with grass seed in order to help fill out lawns in areas where grass alone struggles to take root. It is also occasionally used to help ward off erosion. For this reason, finding a good balance between the grass and clover plants is key to the survival of both. As nitrogen can cause an overgrowth of grass that can overcome clover, it is best to avoid fertilizers with this ingredient.
Though it is possible for white clover seed to thrive close to the surface of the soil, it is best to plant seeds approximately ¼ inch (6.35 mm) deep. Newly-planted seeds need to be kept moist. Once sprouts appear, it is typically best to reduce watering so the roots can develop. Fully-grown white clover plants do not need large amounts of water and have even shown to be somewhat tolerant to drought.
Once the white clover seed has sprouted leaves, the plants can be fertilized. An all-purpose product is usually sufficient. After fertilization, it is typical to see fully-developed plants within approximately two months.
White clover seed can also be started in a pot or tray. Seeds should be planted in moist soil and kept in the shade until they sprout leaves. Then the plants will thrive in full sun. The plants will be ready for transplantation when the roots have fully developed, which can be detected when they start to grow out of the bottom of the starter containers.
Whether kept in a planter or grown in the ground, white clover thrives best when it is regularly watered and fertilized. It is a perennial plant which will go dormant during colder months and reappear in the spring. Once it takes root, the plant will develop a system of runners that give it stability and the ability to spread easily. It will tend to blossom best in the sun, while shady areas will generate more leaves than blooms.
