If so, separate them with your fingers. This will stimulate root growth and help the plants to establish quicker. This should be a soilless mixture especially formulated for container planting. These mixes are weed-free and often contain added nutrients to help plants grow. A peat mixture that contains perlite or vermiculite usually is a good choice.
Fertilizer is especially important when growing plants in wire baskets.
Because the baskets are open-sided, a lot of the water will seep out. You will need to water them more often than you would solid-sided containers. All this watering leaches nutrients. Midway through the season, if you notice that plants aren't producing blooms, add a water-soluble fertilizer high in potassium. Water-retaining polymer crystals help keep the baskets hydrated.
