Soil for roses can be improved by adding organic matter, and adjusting the texture and PH of the rose soil.
By creating the best possible condition for your rose plants, you will ensure better roses. Roses will grow in any reasonably good soil, but they will thrive in improved soil.
The best soil for roses, is fertile, moisture retentive, rich in organic matter, and of a texture that freely allows air and water to penetrate. Soil is made up of particles of silt, sand and clay, in varying proportions. The largest particles are sand, while clay are the smallest. Silt falls in the middle. The size of the particles determines the soil structure.
Sandy soil cannot hold water.(or fertilizer), so plants must be fed and watered often. It does however provide needed aeration, good for root growth.
Clay soil holds water and nutrients well, but has poor drainage. Aeration is also poor.
Silt has booth good drainage, and is easy to work. The best soil for Roses is Loam Which is a mixture of 30-50% sand, 30-40% silt, and 8-28% clay. This perfect mix will drain well, while retaining enough water to promote growth. The aeration is good, so roses can absorb needed oxygen.
To improve the soil structure, you can add organic matter (compost or humas). This can be a valuable amendment to the soil. When added to clay soil, it will make the soil coarser, more airy, and fast draining. Organic matter also provides food for earthworms, which help with aeration.
Sphagnum peat moss, shredded and composted leaves, dehydrated manure, and composted kitchen or garden waste, are wonderful sources of organic matter to add to your soil. The amount you add depends on the condition of your soil. An ideal amount would be 25% of organic matter. Other things that you can add to your soil to amend it are perlite, vermiculite, and pumice. They help improve soil structure but won't adjust the ph. Gypsum will improve clay soil that does not drain well. When worked into the soil, it helps to break up the clay. You can purchase Gypsum in garden centers.
Liquid Wide Range pH Test Kit It's easy to test the ph of your soil with an inexpensive test kit.
The best soil for roses is a ph of 6.0 to 6.5. They grow best in this slightly acid ph, where most of the nutrients they need to thrive are readily available.
If your soil test indicates a low ph, you can raise it by adding limestone. The best type is ground dolomitic limestone (calcium magnesium carbonate), because it contains magnesium. Magnesium is an essential element for plant growth.
If your soil test indicates that your ph is to high, you can lower it by adding agricultural sulfur.
Symptoms of ph that is either to high (or) to low are similar: Yellowing leaves, the plant does not grow well, flowering is not good. The best time to improve the texture of the soil for roses is one to six months prior to planting. The Fall is a good time for preparing the planting beds. The soil will have time to mellow and settle before the roses get planted.
Improving soil should be done on soil that is in workable condition: Dry and friable. To test this, pick up a handful, and squeeze it into a ball. If it sticks together, it is too wet. Wait a few days and try again. Workable soil should crumble in your hand when you try to squeeze it.
