Perennials
Swedberg Nursery has many perennials for you to chose from for a beautiful addition to your yard. Perennials are a must for your flower garden or landscape. Unlike annuals that need to be replanted each year, perennials go dormant in the winter and bloom again each spring.
Frequently Asked Questions
-
What is the difference between an annual and a perennial
An annual will liver for one growing season and need to be replanted every year. A perennial will dia back to the ground at the end of each season and come back from the root. Think annual needs to be replaced annually.
-
How much should I water my new tree?
Trees should be watered in thoroughly when they are planted. This will help remove any possible air pockets made around the roots. On average, a 2” caliper tree requires about 15-20 gallons of water per week. Keep the soil moist around the plant. To check this, dig down 2”and feel the soil, if it is moist you don’t need to water. Lawn sprinklers will not water deep enough for a new tree. Remember sandy soil drains water quickly so it requires more water than clay soil.
-
What are the red bumps on my Maple leaves?
These bumps are known as galls. They are caused by small insects called mites that bite leaves in the spring. Galls on the leaves rarely hurt the tree and there is no treatment that will remove them from the foliage once they are there. Using a dormant oil spray in the spring, right after the foliage has emerged, will help reduce gall formation.
-
When can I plant a tree/shrub?
Trees, shrubs and evergreens can be planted in the spring once the ground has thawed. If it’s spring and you can dig a hole, you can plant a tree.”
-
How much grass seed do I need?
One pound of grass seed will cover 250-300 sq.ft. New lawns will require more seed so figure one pound per 200 sq.ft. for a new lawn.
