Past Articles Library | Rose Replant Disease



If you want to plant some new roses this spring or summer, that's great, but be aware there is something called Rose Replant Disease.

It's not hard to avoid this problem, but you need to be aware of it so you don't have any problems with your new roses.

Here's what it's all about.

Whenever people talk about planting roses, they always assume you are planting in a brand new area, but that is not always the case. Sometimes you may want to replace an old rose with a new one, and therein lie potential problems.

Any soils that have had roses grown in them for 10 or more years need to have the top soil replaced. So if you want to replant an old rose bed that has had roses growing in it for years, or replace old roses with new ones, be careful, because the soil is very likely to be "rose-sick".

The causes of rose sickness are somewhat complicated and are still not fully understood, but what happens is when new roses are planted in the same soil that other roses thrived in for years, they will do poorly and may even die.

How To Avoid This Problem

The best thing to do is to remove as much of the old soil as you can by digging out a hole 2 feet (60 to 65 cm) in diameter and 1.5 feet (45 to 50 cm) deep for each new plant.

Dig in plenty of new organic matter and mix it with soil from other parts of your yard where roses have not grown recently. Take the soil from the old rose bed and spread it in other areas of your yard or garden. Don't worry, the old soil is perfectly safe to use in other areas, it just can't grow roses again for a while.

Lastly give the soil where you will plant your new roses a good dressing of kelp and hydrolized fish fertilizers to help reduce the effect of replant disease.

Note: If you love roses but don't know if you can grow them, an article in our Gardening Idea Blog talks about the top 20 easy-to-grow hybrid tea roses for beginners. They do well in poor soils and less than ideal conditions. Easy To Grow Hybrid Tea Roses

Rotate Certain Crops

Avoid planting potatoes and tomatoes where they grew last year. They carry the same diseases, so it's best to rotate them.

You'll have much healthier plants, and more successful crops.
