Hollyhock


QUICK REFERENCE PLANTING GUIDE

1. Light/Sun Exposure - Full to partial sun.

2. USDA Hardiness Zones - 3 to 8.

3. Planting Distance - 2 to 3 feet apart in ground.

4. Mature Height/Spread - 2 to 3 feet tall by the second year. Will form heavy clumps within three years.

5. Bloom Time - Early summer to fall.

6. Planting Instructions - Dig a hole twice as wide and twice as deep as the roots of each plant. Form a small mound of dirt in the bottom of each hole and spread the roots of each plant over same so that the crown of the plant will be 1½ -2 inches below the surface of the soil after planting. Refill all holes with soil mixture. Firm the soil around the plant with your fingers. Water thoroughly.

GET THE MOST ENJOYMENT

Although Sidalceas are an heirloom perennial native to the U.S. our collection is the result of modern hybridization. While Sidalceas resemble and are related to hollyhocks our new hybrids are much more showy and are more diminutive, manageable plants that bloom all summer long and do not need staking. These selections grow only 2-3 feet tall. They're great for the middle or front of the border in groups or in mass. However, their more diminutive mature size gives them a space in any garden for that charming Old World Hollyhock appeal. From a basal clump of foliage they branch into many flower spikes covered with bright pink, rose red, and white single flowers. They prefer full sun to part sun and do well in any well-drained garden soil that is not allowed to dry out. They are excellent for cutting for indoor bouquets. Cutting also encourages a new flush of buds from lateral shoots. The varieties in this collection will bloom from summer to autumn and are generally free of problems. Suitable for planting in Zones 3 through 8.

SOIL PREPARATION

Although these plants will perform well in average garden soils of all types, we recommend having your soil tested periodically by the local County Extension Office.  These tests can determine if the soil needs any amendments to enhance your plants' growth and performance.  See below for our recommended practice to improve your soil without any additional testing:

1.  Spade or till the soil to a depth of 12-18 inches.

2.  To provide nutrients and improve drainage, add organic matter to your soil by mixing in a 2 to 4-inch layer of dehydrated manure, garden compost, shredded leaves, and/or peat moss.

3.  After active growth begins, periodically feed with Cottage Farms' water soluble Carefree Bud-N-Flower Booster. Plants in containers need more frequent watering and feeding, especially when in active growth and bloom.

CONTINUING CARE

Water - Your plants require 1" of rainfall (or equivalent watering) each week when planted in the ground.  Do not allow plants in containers to dry out.  In a container that is exposed to full sun, water it well at least once every other day, and possibly every day, during periods of intense summer heat.  You may wish to temporarily move containerized plants to an area where they are shielded from the hot summer sun (i.e., in the shade of a tree, on a porch near an overhang).

Mulching - Apply a 2-4 inch layer of shredded bark, compost or other organic mulch around your plants to promote moisture retention, maintain even soil temperatures, and to discourage weed growth.

Weeding - Keep the area around your plants free of weeds. Weeds compete with all plants for food, water and light. Walk around the garden periodically and pull weeds, including the roots, as soon as you see them.

Grooming - Clip off dead or unsightly growth to maintain attractive form and shape.  Deadhead or remove flowers when blooms have faded, leaving as much foliage as possible.  As long as the foliage remains green it will gather sunlight and transmit energy into the root system for the following growing season.

Feeding - Feed your plants once every 2-3 weeks during the growing season with a water-soluble fertilizer such as Cottage Farms' Carefree Bud-N-Flower Booster. Discontinue feeding after September 1st so your plants can harden off for winter dormancy. Resume fertilizing when new growth appears in the spring.

Winterizing - The time to protect your plants in the garden is after the ground has frozen. At that time, apply a winter mulch of evergreen boughs, straws or leaves to prevent lifting of the plant's roots during alternating periods of freezing and thawing.

For container planting, move plants next to your home's southern foundation for added warmth and protection. They may also be moved into an unheated, protected area such as a garage or cellar. If moved to a protected area be sure you water them well once every 7 to 10 days.

In spring, remove the mulch from in-ground plantings.  Also, bring containerized plants back out into the garden sunlight where they will immediately begin to repeat their yearly garden performance.  

 

CAUTION: Not all plant material is edible. Though most plants are harmless, some contain toxic substances which can cause headaches, nausea, dizziness, or other discomforts. As a general rule, only known food products should be eaten. In case of ingestion, please contact your local poison control center at once and advise them of the plant ingested. Keep out of reach of children.
