Get the Seeds
First things first, you need to get your hands on some hollyhock seeds. You can buy them online, at garden centers, or harvest them from existing hollyhocks.
If you’re harvesting, just let the flowers dry on the plant, then collect the seeds.
Prepare the Soil
Hollyhocks love well-draining soil that’s rich in organic matter. Mix in some compost to give those seeds a nutrient boost.
Make sure your planting area gets plenty of sunlight, as hollyhocks thrive under the sun!
Sow the Seeds
Plant your hollyhock seeds about 1/4 inch deep in the soil. Space them around 18-24 inches apart.
This gives them enough room to grow without competing for nutrients and sunlight. Water the area gently after planting.
Water and Wait
Keep the soil moist but not waterlogged. Check daily and water as needed, especially in dry periods.
Germination usually takes 1-2 weeks, so be patient. Soon, tiny sprouts will start to pop up!
Thin Out Seedlings
Once your seedlings are about 2 inches tall, thin them out. Keep the strongest plants and remove the weaker ones to avoid overcrowding.
Aim to maintain that 18-24 inch spacing.
Fertilize
Hollyhocks aren’t heavy feeders, but they do appreciate a little extra love. A balanced, slow-release fertilizer can work wonders.
Just follow the instructions on the fertilizer package for the best results.
Stake the Plants
Hollyhocks can get pretty tall, sometimes up to 9 feet! To prevent them from falling over, stake the plants once they reach about 2-3 feet.
Bamboo stakes or garden canes work well and are easy to find.
Pest Control
Keep an eye out for pests like aphids and rust. A mild soapy water solution can help with aphids.
If you spot rust (yellow-orange spots), trim off the affected leaves and avoid watering their foliage.
Enjoy the Blooms
In their second year, your hollyhocks will reward you with stunning blooms. Enjoy the sight of their vibrant colors swaying in the breeze.
They can also make for lovely cut flowers to brighten up your home!
