How often should I fertilize my plants? - Ward's Nursery & Garden Center? ›

Vegetable gardeners can fertilize their garden beds about once a month with a quick-release fertilizer or about once a season with a slow-release fertilizer. Some gardeners prefer to feed their flowers and plants with a liquid-soluble plant food once every one to two weeks.

When they're more actively growing in the spring and summer, they benefit from a little liquid fertilizer mixed into their water about once a month. If you're not one to remember to do that, go for slow-release granules or a nutrient tab you can just push into the soil every few months or so.

Use with water-soluble fertilizers, follow the mixing instructions, and water the soil at the plant's base with a watering can or hose attachment. This is good for feeding container plants and vegetables. This approach is similar to base application, but the water is applied to the leaves rather than to the soil.

"Fertilizer can easily burn young plants, so I generally use organic matter, such as aged compost, to amend the soil before planting," she says. Two to three weeks after planting, you can spread fertilizer around the soil just below the outer canopy of the plant.

Always follow the manufacturers recommended rates and application methods. Fertilize outdoor plants in the coolest part of the day, such as early morning or late evening, especially in hot summer weather. Always water in fertilizers well to distribute nutrients throughout the soil profile and to prevent burning.

Mid to end of APRIL – spring fertilizer – 32-0-6 slow release (fast acting) Early to mid JUNE (6 weeks later) – early summer fertilizer – 25-0-5 – 50% slow release. Mid to late JULY (6 weeks later) – late summer fertilizer – 25-0-5 – 50% slow release.

Whether gardeners choose Miracle-Gro brand fertilizer or some other brand or type of fertilizer, it's important to understand that over application can lead to poor plant health, and even death.

Over- fertilization can lead to sudden plant growth with an insufficient root system to supply adequate water and nutrients to the plant. Poor root structure reduces the number of flowers and fruit production, and can result in plant growth spurts that won't be supported or sustained.

In general, fertilize plants when you start to see new growth - leaves, buds, roots, etc. - and when planting transplants. Don't fertilize when plants are very dry or drought-stressed. Water the root area before fertilizing.

What perennials not to fertilize? ›

Perennials that require no fertilizer: Included are ornamental grasses, false indigo, ground covers, butterfly weed, bee balm, coneflowers, black-eyed Susans, sea holly, dianthus, asters and veronica.

It's important that the soil is evenly moist before adding the fertilizing liquid. Water until water drips from the pot into the saucer. Be sure to discard any water left in the saucer after the pot is done dripping. Our Grow-How® Team recommends watering a day or two before you'd like to fertilize.

Vegetable gardeners can fertilize their garden beds about once a month with a quick-release fertilizer or about once a season with a slow-release fertilizer. Some gardeners prefer to feed their flowers and plants with a liquid-soluble plant food once every one to two weeks.

Morning watering is actually preferable to evening watering as the plant has time to dry before the sun goes down. At night, water tends to rest in the soil, around the roots, and on the foliage, which encourages rot, fungal growth, and insects.

Most perennials would be happy with a good, all-purpose flower food or organic fertilizer; however, others may have specific preferences or needs. In general, using a natural, organic fertilizer is the preferred method because there is very little chance for burning your perennial plants.

Too much fertilizer (applied too often or too much) can burn or desiccate roots, ultimately killing the plant.

Miracle-Gro® Water Soluble All Purpose Plant Food instantly feeds vegetables, trees, shrubs, and houseplants to grow bigger and more beautiful than unfed plants. Simply feed them every 1-2 weeks. The formula is safe for all plants, and is guaranteed not to burn when used as directed.

Once you've applied your first application in early March or late April, wait 6-8 weeks before giving your lawn a second feeding to avoid over-fertilizing and burning your lawn.

Too much fertilizer can potentially cause a chemical burn on the roots of your plant. In severe cases, it can also cause the whole plant to wilt and die. This is something that you might see happen within a few days of fertilizing. You'll need to act quickly if your plant has been overfertilized.
