Applied too early (and April is too early in Massachusetts), the mulch will slow down your garden by acting as a blanket, preventing warming and keeping the soil colder than the air. Later on, those 2 to 3 inches of mulch will keep down weeds and dress your garden.
The soil around your home and garden is just coming out of its winter hibernation of alternate freezing and thawing. Right now, the top few inches of soil is exceptionally airy, and every time you walk over it, you compress some of the air out. By the end of April, the soil should be ready for gardening but, for right now, avoid doing damage to your soil by walking on it too much.
Everyone likes to prune in April, but follow these guidelines: Prune spring blooming trees and shrubs only after the flowers are finished. Don’t be in a hurry to prune off brown areas on evergreens. They often will regrow the needles that have suffered winter kill. A light scratch with your fingernail on the branch will show green if the wood there is still alive. If you have fall-flowering shrubs, this is your last call to prune them.
The Drought Monitor issued at the beginning of April shows some danger for New England. Portions of the region are ‘unusually dry’ and Vermont and a small area of New Hampshire is in Stage 1 drought. No area rates ‘severe’ or ‘extreme’. But the same map at the beginning of March showed no drought at all in southern New England. The NOAA’s Climate Prediction Center shows a 50% probability for higher-than-average rainfall for April to June for New England; it also shows a 60% probability of above-average temperatures. Keep these forecasts in mind (and watch for updated ones) as you go through the season.
The ground may still be frozen, but planning your 2021 garden should be well underway. If your flower and vegetable seed order hasn’t been sent in, do it quickly. When they arrive, check seeds packets for advice on when to start each variety of seed. Starting them too early often leads to leggy or weak seedlings from having spent too long waiting indoors for warm weather to arrive. Use only sterile soil mixes to prevent damping off (fungal growth) on seedlings.
Give your houseplants room to grow. Not every day is good for outdoor gardening, so now is a good time to do some work indoors. Transplant houseplants in March to prepare them for a spring growth spurt. Always use a clean pot. Scrub salt and dirt from old pots and rinse out new pots before using. Remember to never put a plant into a pot more than one size larger than its current pot. Otherwise, it will disappoint you by spending more energy growing underground than up top. Prune dead or circling roots to encourage new ones to form. Always remove dead leaves, old flowers, and any salt that have built up around the stem of the plant or on top of the soil. And don’t forget to wash the leaves to remove dust from them. Finally, water thoroughly but do not let the pot sit in the water that has drained through.
