24. Pear, water shortage and competition with grass

The tree is suffering from acute starvation and continuous drought, caused by competition with grass. Grass is the worst enemy of young fruit trees. The clearest possible evidence is the appearance of black leaves on the pear trees. This shows that the trees are on the point of giving up all together. To save trees that have reached this stage, remove immediately all grass around the trunks of each tree, one square meter as a minimum. This clear area has to be maintained throughout the year, for at least the next 3 years. To alleviate the shortage of minerals and organic substances, apply well rotted straw-based farmyard manure. In March, apply “Grow More” fertilizer evenly spread over the clean soil area around each trunk of the trees. Follow the recommendations on the packet, do not over dose.
