TOP 5 TIPS for Summer-Planted Landscape Plants
Spring and fall planting has the least amount stressors for new trees, shrubs and perennials IF we have mild weather, and rain. Planting in the summer, with the peak sun, searing heat, and drying winds are just added stressors to new plants but it doesn’t mean you can’t plant. With a few extra precautions you can make it work and your plants will do fine!
1.MOST IMPORTANT! – WATERING
Proper watering is vital to the plants survival. Proper watering doesn’t mean watering everyday. At least 1″ of water a week spring through fall season is the recommended amount. Frequency will vary in the type of soil you have. In clay soils, infrequent yet thorough deep watering is needed. This is because the water doesn’t percolate quickly through the soil. However in a sandy soil, water percolates easily. This requires lower volume and more frequent watering.
A slow stream of hose water for 5 min-10 min should give you a deep thorough watering of trees and shrubs. We like to use one 5 gallon bucket every week to two weeks, with 1/8th holes drilled in to slowly drip.
Perennials should be watered every 3-7 days depending on soil type and weather.
Check the soil regularly by pushing your finger a couple inches into the soil before you water, EACH TIME. You can also insert a screwdriver into the soil and if it’s easily penetrated, the soil is moist. If the soil is moist, wait to water. Remember, even drought tolerant plants need a couple of years to fully mature and need deep thorough watering. Searing heat and windy days can require you to water more often as well since your plants are losing more moisture.
2. PROPER PLANTING TECHNIQUE
Make sure to follow our planting guide (See image below) on the back of our Winter Hardiness Warranty Slip that comes with all trees and shrubs. Mix in compost and slow release fertilizer with beneficial fungi, bacteria, and nutrients, like Bio-Tone, into your native soil to help get your newly planted shrubs, trees, and perennials off to a strong start!
Use 2-3 inches of mulch around your plants to help retain water and keep soil cool during hot and dry days. Mulch around the root zone and keep the mulch 2-3 inches away from the stem of the plant.
4.READ THE LEAVES
Summer-planted plants may wilt regularly if you are under-watering or from heat stress. More water sensitive plants, especially new perennials with shallow root systems, will tell you if they need more water. If there is slight wilting during the day yet they have moist soil, they may be succumbing to heat/light stress if no other signs of pests or disease are present. If they are still wilting after the sun is going down, they are most likely under-watered if the soil is dry or the roots have already been stressed from over-watering. The best method to quickly learn how much water you plant needs is to check it regularly. You’re plant will start establishing it’s roots and watering frequency may decrease.
5. PLANTING TIME
Planting on a cloudy day is also less stressful for them. If the cloudy day is followed by a day or two of rain, all the better! You can also plant in the evening, deeply water, and that give it half a day before it gets blasted with the summer sun.
