To test whether the garden soil is optimal for planting, dig a 12x12 inch hole that is about 18 inches (46 cm) deep. Fill it with water and let it drain, and then do it again and time how long it takes the water to drain. The water level in well-drained soil goes down about one inch per hour. [3] X Research source
When you are weeding, grip the weed as close to the soil as you can. You want to try to remove the entire root section of the weed as well as the part above the ground, or else the weed will grow back.
As you are turning over the soil, make sure to break up any clumps and remove any rocks or pebbles you find.
If you are growing marigolds in a pot outdoors, you should wait until after the last frost to begin the process.
Make sure the pot you are using has drainage holes in the bottom. This will allow water to pass through the pot naturally as it does in the ground. You may want to put a board or plate underneath the pot to catch any excess water or soil that comes out of the drainage holes. [11] X Research source
If you are growing marigolds in a pot outdoors, keep them in direct sunlight.
Water at the roots, and avoid getting the blooms, leaves and stems wet.
When you are picking a spot to transplant, find one that receives a lot of sun.
Also be sure to water at the base instead of over the top of the plant. This could lead to mildew. [21] X Research source In times of drought, water marigolds more consistently. Especially if you live somewhere that has a hot, dry climate, consider putting some mulch on top of the soil at the base of the plants in order to keep the soil appropriately moist.
