How to Plant Colorful Flowering Shrubs: Azaleas and Rhododendrons

A yard without shrubs is like a completed puzzle, minus one piece. The look is almost perfect, but something is missing! Shrubs work wonders — especially ones with bold, colorful flowers. These easy to care for plants instantly fill in gaps in your garden landscape and look fabulous every season. Complete your garden by planting a shrub or two today! Azaleas and rhododendrons are some of the most popular flowering shrubs. Blooming from late spring to early summer, these shrubs thrive in almost any garden. Plus, they come in virtually every color of the rainbow — from bold pinks, purples and reds to soft, muted yellows and whites. As an added bonus, hummingbirds and bees cannot get enough of azaleas and rhododendrons.

For Established Shrubs: Spring feeding helps develop new growth and the production of new flower buds. Sprinkle one cup of Holly-tone per foot of branch spread now. Holly-tone is long-lasting so you’ll only need to fertilize twice in a season. Don’t wait too long, or you risk encouraging green vegetative growth at the expense of flower bud development. Once now, and again in the fall will ensure a perfect Rhody!

For New Shrubs: Spring is the perfect time to plant so pick your favorite color and variety. Before buying, check the plant tag to see if you have enough space for a full-grown shrub. Azaleas and rhododendrons can range from 2 feet to more than 20 feet tall! If planting shrubs in a row, ensure you have enough space to plant 2 feet to 6 feet apart depending on how big your shrubs will get. Now, before you start digging, choose a spot for your shrub and envision the great impact these plants will have on your landscape! Both these flowering shrubs like to hang in the shade and do not grow well in full sunlight. So, make sure you’ve selected a perfectly shaded spot!

Before you start digging, plan for growth. If planting shrubs in a row, ensure you have enough space to plant 2-6’ apart depending on how big your shrubs will get. These flowering shrubs are so easy to care for because most of the work is done before planting. Keep azaleas and rhododendrons bursting with beautiful blooms by picking the right spot and ensuring you’ve got ideal soil for growing. Don’t forget to test the soil! These acid loving shrubs need a soil pH of 4.5-5.5. If your soil test reveals a higher pH, your soil is alkaline. Solve the problem by amending with Espoma Organic Soil Acidifier.

Once your soil is ready, it’s time to plant! Dig a hole as deep as the root ball and twice as wide. Then, remove the shrub from its original container, loosen the roots and dip in a bucket of water. Next, arrange the shrub in the hole, so the top of the root ball is slightly about the ground’s surface. Fill half the hole with compost, peat moss or humus, and mix in 1 cup Holly-tone fertilizer for better blooms. This organic plant food is specially crafted for acid loving plants, like azaleas and rhododendrons. Feeding new shrubs with an organic fertilizer now keeps them well-fed for months, spurs deep evergreen color and dynamic blooms. Fill half the hole with Espoma Organic All Purpose Garden Soil. Now finish planting your shrub by filling the hole with Espoma Organic All Purpose Garden Soil, and add 2-3” of mulch. Water now, and tomorrow, too.
