Dear Bill: When is the best time to fertilize most trees and shrubs?
|
|
Most plants will benefit from a spring and fall application of fertilizer. We recommend using GroMore's custom blended plant foods, which contain slow release nitrogen, sulfate of potash and micronutrients. Choose GroMore Flowering Plant Food for flowering trees and shrubs and GroMore Tree & Shrub Food for evergreens and shade trees.

Dear Bill: Should shrubs and trees be watered after they are planted?
|
|
Yes, all plants should be watered thoroughly after they are planted, and then as needed to keep them healthy. How often you water may vary depending on factors such as the size of the plant, where it is growing, and how much natural rainfall we receive. You will need to monitor your plants water requirements by checking the moisture level of smaller plants every 2-3 days and larger plants and trees every 3-4 days to determine how dry or wet it is to know when it is time to water again.

Dear Bill: When is the best time to fertilize annuals and perennials?
|
|
Annuals will generally benefit from frequent applications of fertilizer throughout the entire growing season. Using GroMore's Flowering Plant Food every 4-6 weeks will keep your annuals growing and blooming all season. Perennials do not require as much fertilizer as annuals. Fertilizing with GroMore's Flowering Plant Food one time in early spring will promote strong blooming.

Dear Bill: How often should plants in containers be watered?
|
|
Plants growing in containers have a limited about of soil and therefore a limited amount of moisture for the roots to tap into, and therefore, need to be watered more frequently than plants growing in the ground. Monitor your container plantings daily and water as needed. During the hot and dry summer months, you may need to water your container plantings every day. Using a water-grabbing polymer such as Soil Moist can help reduce the frequency of watering.

Dear Bill: When should you prune shade trees??
|
|
We recommend pruning shade trees in March/April. This is also a good time to feed them with a good quality, slow release fertilizer. We recommend GroMore Tree and Shrub Food, which contains slow release nitrogen, sulfate of potash, iron and other micro-nutrients.
