Basic Ways on How to Plant and Care for Purple Flowering Shrubs

For first timers, this next short list is all about DIY planting flowering shrubs.

Step 1 - Gather necessary tools.

You need the essential tools to begin planting any of the purple flowering shrubs as listed above. These include shovel, trowel, garden hose, as well as water, mulch, and of course, your choice of shrub varieties or species.

Tools:

Materials:

  • Water
  • Mulch
  • Shrubs

Step 2 - Select the right location

You must have some space where to grow shrubs. Remember that this type of plant grows really high and spreads wider than others. Another consideration is the view. Does it give a more attractive look or block the beautiful from a distance? The keypoint here is that you need to find the best location that serves its main purpose, and as long as it is situated in a soil with the right condition.

Step 3 - Dig a hole

The normal measurement of a hole to make must be 2 feet to 3 feet wide. This allows the root ball to have enough room that eventually assists in growing and spreading. Ensure that the height and depth must be equal.

Step 4 - Place the shrub into the hole

Once you make the perfect hole, place your chosen shrub. Check if you need to loosen the roots. If it’s looking good, fill the hole with native soil (the same removed from digging). Firmly and gently press the soil.

Step 5 - Water

Right after planting the shrub and covering the hole with soil, it’s very important that you water it. Doing this hydrates the plant and minimizes the shock of the roots during transplanting. Apply the needed amount of water to keep its moisture depending on the requirement throughout its growing process.

Step 6 - Add mulch

Around the base of the shrub must be at least a 2-inch layer of mulch. It helps retain moisture on the soil and also prevents the presence of weeds. But do not place at the base of the trunk or this can cause a problem later on. Add more mulch if the previous batch starts decomposing.

Growing purple flowering shrubs is manageable even for beginners. With the basic knowledge and gardening skills, this activity can become fun. You will soon embrace the regularity of taking good care of plants like flowering shrubs.
