Where can I plant Hydrangeas?
With so many Hydrangeas on the market, from large shrubs to compact varieties, there aren’t many places these plants can’t go. For location, our advice is to plant them where they well receive morning sun and afternoon shade. Here are some ideas for where you can plant Hydrangeas:
- Shrub borders
- Potted plants on the patio
- Large containers
How do I plant Hydrangeas?
Our potted Hydrangea plants can be planted straight away upon arrival. Here are our step-by-step planting instructions:
- Plant in Spring or Autumn.
- Plant in well-drained soil (if soil is heavy, add roughage such as pine bark mulch).
- Dig a planting hole 2 feet wider than the plant (keep the depth of the hole consistent with the size of the plant so your plant sits level with or just higher than the surrounding soil).
- Do not over water, esp. in clay soil. This can lead to root rot.
How do I care for Hydrangeas?
- Water at a rate of 1 inch per week throughout the growing season. Deeply water 3 times a week to encourage root growth. Big leaf and smooth hydrangeas require more water, but all varieties benefit from consistent moisture. Watering in the morning will help prevent hydrangeas from wilting during hot days.
- Add mulch underneath your hydrangeas to help keep the soil moist and cool. An organic mulch breaks down over time, adding nutrients and improving soil texture.
- Apply fertiliser based on your specific hydrangeas. Each variety has different needs and will benefit from different application timing.
- Big leaf hydrangeas need several light fertiliser applications in March, May and June.
- Oakleaf and panicle hydrangeas do best with two applications in April and June.
- Smooth hydrangea plants only need fertilisation once, in late winter.
- Prune in late winter and early spring. Prune as far back as you want right above the first leaf joints. It will grow from that point onward, getting larger each year.
