Creating a lush and vibrant hanging basket display is a rewarding gardening project. However, the real challenge lies in maintaining its beauty after planting. Proper care, including watering techniques, climate considerations, and timely fertilization, is crucial for the longevity and visual appeal of your hanging baskets. In this detailed guide, we'll explore the best practices for nurturing your hanging baskets to ensure they remain a stunning feature of your outdoor space.
After planting your hanging basket, the first step is to water it thoroughly to help the compost settle around the plant roots. Place your basket in a sheltered area, ideally in a heated greenhouse with a minimum temperature of 16°C (60°F), to promote root development. Avoid additional watering until you notice the plants beginning to wilt, which signals the need for a good soak. Establish a regular watering routine from that point on.
In the UK, the risk of frost dictates the outdoor placement of hanging baskets containing tender plants. It's generally safe to hang them outside from late May in southern regions to early to mid-June in the north. To get a head start and extend the display season, prepare your basket in late March to mid-April and nurture it in a frost-free greenhouse. By the time the frost threat subsides, your basket will be lush and ready to impress.
The frequency of watering your hanging basket depends on its location and the weather. Expect to water daily, and during particularly hot days, you may need to increase this to twice or more. If you've incorporated slow-release fertilizer, consider supplementing with a soluble fertilizer later in the season for an extra boost. For acid-loving plants like surfinia petunias and pansies, use an acidic soluble fertilizer.
Mid-season, it's beneficial to prune back plants like surfinias by up to half to encourage fresh growth. This rejuvenation will give your basket a new lease on life within a couple of weeks. However, be cautious with plants like impatiens that are sensitive to overfeeding and high salt levels.
From August onwards, monitor baskets with slow-release fertilizer for signs of nutrient deficiency, such as dull or yellowing leaves. If noticed, start liquid feeding every three days to maintain performance until frost ends the season.
When frost damages your tender perennials, such as geraniums and fuchsias, remove them from the basket for overwintering in a frost-free environment. This is also an ideal time to propagate new plants from cuttings. Baskets with suitable lining material can be reused the following year by cutting back foliage, removing debris, and storing in a frost-free area with minimal watering.
In spring, when new growth emerges, create holes in the compost with a stick and add fresh slow-release fertilizer. Top up the compost and care for the basket as if it were new.
By following these guidelines, your hanging baskets should thrive and provide a beautiful display throughout the season.
