Lavender bushes (Lavandula spp.) , hardy in U.S. Department of Agriculture plant hardiness zones 5 through 10, and white roses like “Iceberg” roses (Rosa “Iceberg”), hardy in USDA zones 4 through 9, possess a few comparable conditions for healthy development. Both plants favor well-draining soil and full sunlight. But there are two critical ways that these plants are considerably different. Roses prefer acidic soil with a pH of approximately 6.5 to 6.0, whilst lavender requires its soil pH to drop between 6.4 and 8.1. In addition, roses need soil that is not too wet nor too dry, whilst lavender likes soil on the dry side once established. When landscaping a corner using these two good plants together, they ought to separated by means of a pathway or gap at the garden that allows them to live healthy but somewhat separate lives.
Preparation
Decide on a corner of the yard that sees full sunlight and contains well-draining soil.
Designate one place in your preferred corner for white roses and one place for lavender. If the corner falls on a slope or a incline, the roses need to be set below the lavender to ensure that water runoff and fertilizer from the roses does not contaminate the lavender’s growing area.
Check the soil pH in the chosen places with a meter purchased from a local nursery or garden center.
Dig a hole to the root ball of every plant, separating the two types of plants by at least 2 feet. Consider putting a barrier like a bench or a huge landscaping stone between the two sorts of plants. This makes the division seem natural.
Planting Roses
Amend alkaline soil with peat moss in the place where you plan to plant your “Iceberg” roses, to make it more acidic. Peat moss lowers soil pH by 1 unit for every 2.5 pounds applied to every square yard. Peat moss also enhances drainage.
Sprinkle 1 cup of superphosphate into the hole where the roses will be implanted, unless the roses to be planted are bare-root roses, in which case you need to sprinkle the superphosphate above the ground after the roses are in the ground.
Set the increased root ball at the hole.
Fill the hole around the rose root ball with amended soil, and quit about halfway.
Water the rose with a half gallon of starter alternative or root stimulator.
Fill in the remaining portion of the hole using the amended native soil.
Water the rose having an additional gallon of root or starter stimulator.
Planting Lavender
Amend acidic soils with agricultural lime to raise the soil pH to approximately 7.0. The total amount of agricultural lime used depends upon your current soil pH and the sort of soil you have. It is possible to use roughly 6 pounds per 100 square feet to raise the soil pH by one unit. Utilize more lime for clayey soils, and less lime for sandy soils.
Insert the lavender root ball into the hole.
Backfill the hole.
Water the lavender greatly with 1 gallon of water.
